TABLEBOARD

The tableboard can now be mounted on the pedestal using four screws, adjusting the nuts so the top of the
tableboard is flush with the top of the machine bed plate.

BOBBIN WINDER

The bobbin winder should be secured to the table top so that its pulley will be located directly in front of the
sewing machine belt and will bear against the belt when in operation. The base of the winder has two
elongated attaching holes, which allow the mechanism to be moved closer to or farther away from the belt
as needed. The pulley of the winder, when in operation, should exert only enough pressure against the belt
to wind the bobbin. Regulation and operation of the bobbin winder is described under "Winding The
Bobbin", under "Instructions For Operator's".

BELTS

These machines are equipped to use either #1 "Vee" or round belts.

LUBRICATION

CAUTION! Oil has been drained from the main reservoir before shipment and the reservoir must be filled

before starting to operate.

Lubricate machine thoroughly, in accordance with instructions which follow, and run slowly for several
minutes to distribute the oil to the various parts. Full speed operation can then be expected without
damage.

RECOMMENDED OIL

Use a stainless water-white straight mineral oil of a Saybolt viscosity of 90 to 125 seconds at 100° Fahrenheit
in the main reservoir. This is equivalent to Union special specification No. 175. Fill main reservoir at plug
screw (B, Fig. 3) and check oil level at gauge (C): oil is at maximum level when needle is in yellow band
marked "FULL". Oil should be added when needle is in yellow band marked "LOW".

It is recommended that a new machine, or one that has been out of service for an extended period, be
lubricated as follows: Remove the head cover and directly oil the bearings of the needle bar link, the take­up and its lever and needle bar. Replace end cover, as no further hand oiling will be required.

Oil may be drained from main reservoir by removing plug screw (D, Fig. 3).

OIL GAUGE

The oil gauge is set at the factory to show the proper oil level in the reservoir. Should and adjustment
become necessary, the following steps should be followed:

1. Place the machine upright on a level table or bench.

2. Remove the reservoir plug screw (located below the handwheel and near the bottom of the

machine).

3. Oil should be added or removed so that the oil level is approximately 1/8 inch below the bottom edge

of the hole.

4. Loosen lock nut (E, Fig. 3) on the calibrating screw (F), and turn screw left or right so the gauge needle

rests on the yellow band marked "FULL" on gauge (C).

5. Tighten lock nut and replace plug screw.

SELF-PRIMING HEAD OIL SIPHON

Class 63900 machines are equipped with a self-priming head oil siphon. When the machine is started, oil
splashes on the priming cup felt, filters through the felt and trickles down the vertical oil tube, thus priming
the siphon. Once the prime is established, it is maintained, unless the felt is removed. The siphon operates
twenty-four hours a day, removing oil at the rate of six to twelve drops per minute, which, of course, far
exceeds the rate at which oil collects in the head.

INSTALLING AND MAINTENANCE OF OIL SIPHON

A newly installed siphon starts its action within three to five minutes after the machine is operating. However,
it may be twenty minutes or so before all the air is removed from the line and the siphon is in full operation.
Within an hour, there should be a distinct reduction of the oil in the head sump. If the siphon does not
function, determine if the siphon intake tube, located in the head, is inserted in the felt block and that the
plastic tube is connected at both ends. If the above two items do not correct the siphon, replace the siphon
felts as described below.

The felt in the priming cup is designed for a specific purpose. This felt, No. 666-237, is to meter the flow of
priming oil and to prevent the entrance of air. The felt also acts as a filter and keeps the siphon clear of lint.

If the priming cup felt and the intake felt (666-214) becomes contaminated with an excessive amount of lint,
it may be necessary to replace the felts. The priming cup felt is replaced by removing access plug at back
of machine and replacing felt 666-237. For the best initial self-priming condition, the felt of the siphon should
be installed dry. The intake felt is replaced by removing the end cover.

However, if for some reason the priming cup felt has been oiled before installing, the siphon may fail
because air is trapped in the felt. As a precaution, remove felt from cup. Then, while squeezing the felt
between the fingers, saturate it well with oil. In other words, squeeze out the air and replace it with oil. This
prevents the trapping of air, and no trouble should be experienced when starting the siphon.

THREAD

While the direction of the twist in the bobbin thread is immaterial, the direction of the hook rotation favors
the use of a left twist thread in the needle. To determine the direction of twist, grasp a short length of thread
between thumb and forefinger of each hand. Turn the thread away from you with your right hand. If the
strands unwind, it is a left twist, if not, it is a right twist.

REMOVING THE BOBBIN CASE

To remove the bobbin case, turn handwheel in operating direction until
needle reaches its highest position. Using the left hand, reach in under the
throat plate at left end of machine, open the bobbin case latch (A, Fig. 5),
and pull the bobbin case out of the sewing hook.

Opening the latch retains the bobbin in the case. When the latch is closed,
the bobbin is released and can readily be removed.

WINDING THE BOBBIN

Thread the bobbin winder by leading the thread from the supply down
through the eyelet (A, Fig. 6), down between the tension discs, and
under the tension post. Press an empty bobbin on the winder shaft (B),
up to the stop, wind the end of thread around the bobbin a few turns
in a clockwise direction and press downwardly on hand lever (D) until
pulley is moved into contact with machine belt, and is locked in that
position. When the machine is operated, the bobbin will be rotated
and filled until the thread engages the automatic throw-out member,
which disengages the pulley. The extent to which the bobbin is filled
can be varied by regulating the screw (C).

The tension post bracket is mounted on the winder base, and can be
shifted from left to right by loosening screw (E) so that any tendancy
of the bobbin to wind unevenly may be readily corrected.

The purpose of the bobbin winder is to assure an operator of a full
bobbin at all times. When the bobbin in the machine is used up,
replace it with the full one, and begin to wind the empty on immedi­ately. Bobbins can be rewound while the machine is sewing.

THREADING THE BOBBIN CASE

The bobbin case (A, Fig. 7) should be held between the thumb,
forefinger and second finger of the LEFT hand.

The bobbin (B) itself should be held between the thumb and forefinger
of the right hand with thread coming off the bottom of the bobbin.

11

THREADING THE BOBBIN CASE (CONT.)

Place the bobbin in the bobbin case. In one continuous motion, with thumb and
forefinger of right hand, draw the bobbin thread through diagonal slot in bobbin
case (A, Fig. 8) under the tension spring (B) and into self threading slot (C) on case.
Mote direction of the rotation of the bobbin as the end of the thread is pulled when
looking at the bobbin case from the back. The bobbin should rotate counterclock­wise.

REPLACING THE BOBBIN CASE

Have the needle bar at tis highest position, allow about two and one half inches of

thread to hang free. The bobbin case latch should be opened with the left hand,
and by reaching under the throat plate and through the bed plate extension, it should be placed part way
into the sewing hook. the latch should then be released and bobbin case into position.

INSERTING THE NEEDLE

Insert the needle into the needle bar as far as it will go, with the spot (sometimes called scarf)
towards the right, facing the handwheel. Tighten the nut securely.

The cross hole in the needle bar, about 1/4 inch from the end (A, Fig. 9), is to show the operator
when the needle has been inserted as far as it will go, and to provide a means for cleaning the
accumulated lint from needle hole so the needle will seat properly.

THREADING THE NEEDLE

Threading diagram (Fig. 3) shows the places where the needle thread passes. Please note that
the needle thread passes through the needle eye from left to right.

PREPARATION FOR SEWING

With your left hand, hold the end of the needle thread, leaving it slack, and turn the handwheel in operating
direction until the needle moves down and up again to its highest position. Pull up the needle thread and
the bobbin thread will come up with it, through the needle hole in the throat plate. Draw both threads under
the presser foot.

TENSIONS

A perfect stitch is one in which the needle thread and bobbin thread are locked
together in the center of the material being sewn. A stitch of this kind is secured by
regulating the tensions on both threads.

BOBBIN THREAD TENSION

The tension on the bobbin case is applied by means of a set screw (A, Fig. 10) which

regulates the tension spring (B). The tension on the spring is correct when it is just
sufficient to hold the bobbin case and bobbin suspended by the bobbin thread. The thread should not be
in the eyelet for this adjustment check.

12

BOBBIN THREAD TENSION (CONT.)

Remove the bobbin case from its holder and turn set screw in spring
in a clockwise direction to apply more tension or counterclockwise
to release tension.

When the bobbin thread tension is correct, it rarely becomes nec­essary to make any changes as varying the needle thread tension
will usually attain a good stitch.

NEEDLE THREAD TENSION

The needle thread tension is varied by turning the tension regulating
nut (G, Fig. 3). Turning the nut in a clockwise direction increases the
tension, while counterclockwise decreases it. This should not be
done when the presser foot is in its raised position, but is generally
done while the machine is sewing on a piece of scrap material.

CHANGING THE STITCH LENGTH

Unless otherwise specified machine Styles 63900AM, AML and AT will
be equipped with upper feed regulator gear No. 63949-39 and
lower feed regulator gear No. 63949-41 to produce 9 stitches per
inch (S.P.I.), while Styles 63900AW, and AAE will be equipped with
upper feed regulator gear No. 63949-37 and lower feed regulator
gear No. 63949-43 to produce 10 S.P.I. Other gears are available and may be ordered separately. Refer
to "Gear Chart" below for the gears necessary to produce S.P.I. other than previously described.

GEAR CHART

S.P.I. UPPER GEAR LOWER GEAR
6 63949-47 63949-33

7 63949-44 63949-36
8 63949-41 63949-39
9 63949-39 63949-41
10 63949-37 63949-43
11 63949-36 63949-44
12 63949-33 63949-47

To remove feed regulators gears, first remove feed drive gear cover located under arm of machine. Now
loosen screws (A and B Fig. 11) and slide gears (C and D) off their respective shafts. Replace with gears for
desired stitch length. After new gears have been installed be sure to reset needle feed stitch length to
agree with the continuous turning roller feed.

13

TIMING THE NEEDLE FEED WITH THE CONTINUOUS TURNING ROLLER FEED

Open top cover (A, Fig. 12) in the head of the machine and loosen needle
frame drive segment locking nut (B). Set connection stud (C) to point of
maximum number of stitches per inch of needle feed. This would locate the
connecting arm at letter "S".

Loosen two set screws on the needle frame drive eccentric (D). Rotate the
handwheel until the needle bar is at the bottom of its stroke. Rotate the
eccentric only, until the timing line (2) on the connecting arm and the
eccentric hub coincide. Tighten all screws, on every thick seams that
cause thread breakage advance needle feed timing slightly.

Rotate handwheel until the needle bar is at bottom of its stroke. The needle
bar should be vertical. If it is not, loosen clamp screw (F) and move needle
bar frame forward and backward until bar is vertical. Tighten screw,
making sure allside play is removed from between the needle bar frame
and the segment.

To set needle feed with roller feed loosen needle frame drive segment
locking nut. Set connection toward higher designated letter on segment
for approximate setting. Vary the needle travel so as to obtain the least
amount of needle deflection when the needle enters or leaves the thickest
section to be sewn.

PRESSURE ON MATERIAL

The presser spring (A, Fig. 17) should exert only enough pressure on the feed
rollers to make the work feed uniformly. To increase the pressure on the
preser foot, turn presser spring regulator (B, Fig. 17) in a clockwise direction.

Turning the regulator counterclockwise decreases the pressure.

SETTING THE NEEDLE BAR TO HEIGHT

The three lines engraved on the needle bar are used in setting needle
bar to height, and are referred to as TIMING LINES.

Th middle and lower lines are used for Styles 63900M, T, and W. For
63900AM, AML, AAE, AT and AW the upper and middle lines are used.

When the needle bar is at its lowest position the upper timing line (B, Fig.

13) should be EVEN with the lower edge of the lower needle bar frame
(A).

To change the position of the needle bar, turn handwheel until the bar
is at its lowest position. Then, loosen the clamp screw (C) and move the
bar to the proper timing line. Keeping the needle bar line at its lowest
position, tighten the screw securely.

14

TIMING THE HOOK

Remove throat plate. Loosen three set screws (A) in the hook, and
hold the hook and the bobbin case holder in such a position as to
prevent interference with the needle. Turn handwheel in operating
direction until the needle bar is at its lowest position, and continue
to turn the handwheel until the needle is ascending and the middle
timing make (Fig. 13) used in setting the needle bar is even with the
lower edge of the needle bar frame (A).

Turn the hook on the shaft until the point of the hook is even with the
center of the needle and as close to the needle as possible without
deflecting it. A spacing of .003 to .005 inch between the needle and
the point of the hook is satisfactory. With the hook in this position,
tighten the set screw opposite the hook point securely. Then,
tighten the two remaining screws securely, and recheck the timing
of the hook with the needle. At the hook timing position the top of
the eye of the needle should be about 1/64 inch below the bottom
of the hook point.

Replace throat plate, allowing 1/32 inch clearance between the outside
edge of projection and the inside edge of bobbin case recess.

NEEDLE GUARD INSTRUCTIONS

In the hook, at the right side of the needle hole in bobbin case holder (B,
Fig. 15) is found a needle guarding surface (A, Fig. 15).

The purpose of this guarding surface is to prevent the hook point (C) from
coming in contact with needle (D) at loop-taking time, should the needle
be deflected toward the hook point. The needle guard will deflect the
needle slightly when needle is at bottom of its vertical travel if the hook is
properly timed. (At loop-taking time there should be little or no deflection
of needle by the needle guard.)

For additional needle clearance, especially with use of larger needles,
removal of some needle guarding surface may necessary.

Before metal removal from the guarding surface all related settings should be checked as follows:

1. See that the needle bar is set to correct height.

2. Check for proper hook timing.

3. Rotate the handwheel in operating direction by hand.

Check for excessive needle deflection beyond what is
cited on preceding page as a desirable condition.

4. If needle deflection is excessive, follow steps (A) and (B)

below.
(A) Remove bobbin case holder from hook.
(B) Remove excess metal from the needle guarding

surface. This may be done by using a diamond file
No. TT60 or fine emery cloth (#320), with one end secured to the bench, and rubbing the
guarding surface back and forth until sufficient metal is removed. When metal is being removed
from needle guarding surface, the bobbin case holder should be reinserted frequently and
tested until proper needle guarding is obtained.

15

NEEDLE GUARD INSTRUCTIONS (CONT.)

CAUTION! Damage to the hook point may result if too much metal is removed from the needle guarding

surface.
The bobbin case holder should be thoroughly cleaned before reassembly into the hook base.
When altering needle guarding surface, it is suggested that the hook NOT BE REMOVED or disturbed from its

timed position.
The bobbin case holder only may be removed by removing gib screws and gib and pulling on bobbin case

stem as the handwheel is rocked backward and forward slightly.

HOOK LUBRICATION

CAUTION! Do not run the machine without the bobbin case in the

hook as hook damage may result.

With the bobbin case in hook, run machine for a full minute. Place a piece
of white paper directly under the hook and continue running the machine.
After about five seconds, remove the paper and a definite and distinct
pattern of oil spots should be observed.

Should more or less oil be required, turn oil control adjusting shaft (H, Fig.

3), located on the front of the machine just blow the cloth plate surface,
in direction of the change required. After a change in the hook oil flow,
the machine should be run about one minute before checking for the
desired oil flow.

When locating presser bar guide (C, Fig. 17) presser foot must rest directly
against throat plate. Proper setting of guide is 5 3/64 inches between
underside of presser bar guide and the top of throat plate (Fig. 17). To
obtain this setting, remove pressure from the presser spring (A) and loosen
set screw (D). Tap on presser foot to insure it is down against throat plate.
Set guide to the 5 3/64 inch dimension, center foot by turning it so needle
enters the middle of its slot and retighten screw (D). Apply pressure to top

feed roller by turning regulator (E) clockwise.

Set needle thread pull-up bracket (F) so that underside of wire is 4
5/8 inches above throat plate (Fig. 17).

Presser bar conection (G, Fig. 17) should be set about 1/16 inch
below prese bar guide (C). Accomplish this by loosening lick nut (A,
Fig. 16), and relocating stop screw (B) on lifter lever bell crank (C),
located at the back of machine, under bed plate. turning stop
screw to right or left, properly sets presser car connection. Tighten
lock nut (A) to lock stop screw.

TENSION ASSEMBLY ADJUSTMENT

Test check spring tension (A, Fig. 18). There should be enough tension to
assure a good returning snap when the spring is depressed and released.
Should it require adjusting, loosen set screw in head located under arm
and to the right of tension assembly and remove tension assembly.
Partially loosen tension post set screw (B) in tension post socket (C). Turn
tension post (D) counterclockwise until check spring moves away from
upper stop (E) and has no tension on it. Turn tension post (D) in a
clockwise direction until spring again touches upper stop (E). Proceed
further in same direction approximately 1/4 turn until desired tension is
obtained. When correctly set, tension post set screw (B) should be drawn
up snugly, yet not forcefully. Further adjustment of check spring tension
can be made by inserting a screwdriver into slotted end of tension post
(D) and turning in required direction.

Replace tension assembly with check spring about 3/8 inch above thread take-up bracket (A, Fig. 19).
Replace tension post assembly while presser foot is resting on throat plate.

TENSION RELEASE

Tension release should be set so as not release when sewing over seams
or when presser foot is raised. Adjustment of tension release cam (H, Fig.

17) and in and out position of tension assembly are required for proper
operation.

The in and out position of the tension assembly is correct when the
tension discs are in line with the check spring eyelet (B, Fig. 19). Set the
stop screw (C, Fig. 19) so that when the flange of the tension assembly
rests against it, this position is maintained. Tighten the tension assembly
set screw.

The tension release cam (H, Fig. 17) should now be positioned by
loosening set screw (J) and then rising or lowering cam (H) to suit the
sewing conditions. The average release point is between 1/4 and 5/16
inch of presser foot lift above the throat plate. Tighten tension release cam set screw securely.

THREAD CONTROL

Check the adjustment of tension assembly (A, Fig. 20) and
check spring tension. There should be enough tension to insure
a good returning snap when spring (B, Fig. 20) is depressed and
released. The check spring tension is adjusted from about 1 to
1 1/4 ounces when measured with a postal scale, No. 21227DN,
(C, Fig. 20). This is measured when the check is 1/32 to 1/16 inch
from the stop. The tension post set screw should be drawn up
snugly but not forcefully tightened (B, Fig. 18). The tension
release pin should move freely in the tension post (D, Fig. 18).
The check spring eyelet (B, Fig. 19), located just below the
tension discs, should be set for correct height as follows:

With a thread running from the tension post to the thread take­up bracket (A, Fig. 19) in a straight line, the check spring eyelet
should be set 1/16 to 1/8 inch below the thread line (Fig. 19). Be
sure the eyelet is set close to the tension discs so that the check
spring will pass freely over it without obstruction. After making this setting, proceed to thread machine as
per threading diagram (Fig. 3).

17

THREAD CONTROL (CONT.)

Sew slowly on a piece of material and observe the action of the check spring. The thread from the check
spring to the take-up bracket should be taut when the take-up is at the bottom if its stroke. Slight changes
in needle thread tension may necessary at this point, but a reasonable tension should be used to maintain
a uniform and consistent stitch. The machines are sewn off with 4 to 8 ounces maximum needle thread
tension on T120 or similar thread, using a postal scale (A, Fig. 21). Depress check spring when checking
tension. The check spring will feel heavy to you, but this is a required setting for Class 63900, and as a result,
the tension on the discs can be reduced.

BOTTOM COVER

Before removing bottom cover, place machine on bench so that the plug screw is accessible from
underneath. Remove this plug screw and catch reservoir oil in some convenient container. Tip machine
back, loosen and remove the two cover screws. Cover should be tapped free with a wooden block or
mallet. Do not pry the cover loose with any sharp instrument as the gasket may become damaged.

CAUTION! When the bottom cover is removed, care should be taken not to mar or scratch the gasket

seat area of the machine bottom.

Before replacing cover, the machine gasket seat should be wiped clean and free of all lint and dirt. The
cover gasket should also be inspected for damage and cleaned of dirt. Two additional gaskets are used
to seal the bolts and must be cleaned before assembly. Carefully set the cover in place and tighten the two
bolts securely.

To replace a damaged cover gasket, proceed as follows:

1. Clean cover gasket recess of any foreign matter.

2. The gasket in cross section is triangular in shape with a groove in the top or widest part. With the cover

resting as it does in the machine, oil distributing plate to your right, begin inserting in the middle of the
back recess. The grooved wide edge of the gasket should be up and the ling sloped edge inward.
Continue pressing the gasket into the cover recess until gasket is in place.

The bolt sealing gaskets may have a tendency to fall out when the cover is being installed and may be
temporarily cemented in place by applying grease to their recesses. Torque to 72 inch lbs.

HOOK SHAFT

The hook shaft (A, Fig. 22) is held in
position by the pinion (B) and collar
(C) thrusting against hard steel wash­ers (D) between the long left hand
bushing (E) and the short right hand
bushing (F).

Should hook shaft setting be dis­turbed, the left and right position can
be determined by measuring from the
hook end of the hook shaft to the
point of a new needle (G) and read­ing 9/16 inch on a scale.

18

HOOK SHAFT (CONT.)

To reposition the hook shaft, loosen the set screws of the pinion and collar and establish the 9/16 inch
dimension. Move the pinion and thrust washer against the left bushing, and after making certain one of the
set screws in on the shaft FLAT, tighten both screws securely. Liberally coat the collar and its washer with
oil and press the collar away from the pinion so as to remove all end play and tighten both set screws
securely.

Hook oiling is accomplished by a high speed rotary pump on the end of the hook shaft. The quantity of oil
supplied to the hook is regulated by the longer or shorter path the oil is required to travel through the
metering felt of metering cup (G, Fig. 23). (Increase or decrease of oil supply is controlled by a dial (P, Fig.

23) with an arrow marked "INCREASE", found below the cloth plate.) The hook oil feed roller (A, Fig. 23) which
rests against the metering cup felt serves not only to feed oil to the unit from the oil reservoir, but filters the
oil as well.

REMOVAL OF OILING DEVICE

The following steps are necessary to remove hook oiling device:

1. Remove hook oil feed roller (A, Fig. 23).

2. Remove hook oil control finger (B).

3. Apply finger pressure to hook oil control shaft (D) to prevent loss pump disc pivot pin (E); using Allen

wrench, loosen set screw (C). Move assembly slowly to right, being careful not to drop pivot pin
located on the end of the hook oil control shaft. When pivot pin is clear of pump disc (F), disc is free
to fall.

4. Remove metering cup (G) along with oil supply felt (K) and air seal felt (J).

5. Remove cop (H) from hook oil control shaft.

19

REASSEMBLY OF OILING DEVICE

Before reassembly, the end of the hook shaft, its spiral groove and the pump disc should be thoroughly
cleaned. Remove any end play found in the hook shaft and determine that the 35/64 inch dimension has
been maintained (Fig. 22).

The following steps are necessary to reassemble the hook oiling device:

1. Remove and separate the air seal felt (J, fig. 23) from oil supply felt (K).

2. Make sure small end of air seal spring (R) is located on boss of metering cup behind felt attached to

cup. Position the metering cup (G) and air seal spring on the hook shaft (S) with open end toward
handwheel end of the machine (Fig. 23).

NOTE: The hook shaft should pass through hole of felt attached to metering cup.

3. Position oil supply felt (K, Fig. 23) on the hook shaft, making certain the felt's projection extends into

dovetail of metering cup.

4. Position air seal felt (J) on hook shaft.

5. Insert pump disc (F) into assembly tool No. 21227BY, with the stop pin on the spring side of tool, 180°

from handle. Insert disc approximately half way into the spring and center in tool (Fig. 25).

6. Insert hook oil control shaft (D, fig. 23) and its bushing (L) part way into its boss which is located directly

behind the hook shaft, being careful NOT TO DROP the pump disc pivot pin (E).

20

REASSEMBLY OF OILING DEVICE (CONT.)

7. A clearance cut on the edge of the metering cup, located between the dovetail and the long

horizontal slot, has been provided for the pump disc tool and should be facing you (Fig. 25).

8. With the fork of the tool in line with the meter-

ing cup clearance cut and centered about
the hook shaft end, press felts to the left with
tool until the pump disc is in contact with end
of the hook shaft.

9. Press hook oil control shaft bushing (L) to the

left until control shaft (D) is approximately 1/
16 inch away from pump disc (F). Make sure
the control shaft pivot pin (E) seats in the
depression at the center of the pump disc.
Tighten set screw (C, Fig. 25) and withdraw
assembly tool. Be sure sir seal felt (J) has
seated against the pump disc.

10. Turn the hook oil control shaft (D, Fig. 26) until

screw hole (M) is accessible. Manually rotate
pump disc (F) so its stop pin (N) is 90° above screw hole.

11. Rotate metering cup so the short slot (T) is 180° from stop pin (N). Now, install hook oil control finger

(B) by first hanging the hooked portion of finger over the stop pin and lowering to insert the projection
at bottom left into the short slot of the metering cup. Tighten the finger in place by means of screw
and washer, making sure the hook oil control finger
does not bind or distort metering cup.

12. Assemble the hook oil feed roller (A, Fig. 27), and

rotate the metering cup so that the roller contacts
the metering cup felt at point (U, Fig. 27). Turn the
oil control adjusting shaft (P, Fig. 27) in the increase
direction until projection stops against the stop in
(this is maximum oil supply) and install the cog (H,
Fig. 27) on the hook oil control shaft. After meshing
the teeth, tighten set screw securely.

13. Check for proper contact of the hook oil feed roller

and the metering cup by turning the oil control
adjusting shaft through its complete travel and ob­serve the feed roller turning as the metering cup
turns. With the oil control adjusting shaft set at
maximum, the feed roller point of contact with the
metering cup felt should be at the mid-point of the
slot that permits the metering cup felt to enter the
metering cup.

NOTE: The feed roller should be in contact with the metering cup felt through its complete travel.

UPPER MAIN SHAFT

In a high speed machine, the alignment of the take-up mechanism is extremely important and is controlled
by the left and right position of the upper main shaft. Should the main shaft position be altered, it is
imperative that the take-up alignment be checked before operating.

21

UPPER MAIN SHAFT (CONT.)

TO CHECK FOR ALIGNMENT

1. Remove the presser bar spring, washer and regulator screw.

2. Rotate the handwheel so that the needle bar is at the
bottom of its stroke. Loosen hexagonal head screw
on back of the presser bar roller bracket, and set
screw on left side or roller bracket. Then loosen screw
on presser bar guide and remove presser bar, presser
bar spring washer and presser bar guide.

3. Remove the upper left plastic plug on the back of the
machine and loosen screw in plug hole. Remove
take-up lever pin. With light inward finger pressure,
move the take-up lever to the take-up lever boss.
There should be a small amount of interference be
tween the lever and the boss. With light outward
finger pressure, move the lever across the boss face.
There should be clearance between the boss face
and lever. These two tests, in effect, are checking
the lateral play of the take-up and provide for opera­tion of the take-up in the center of the lateral play.
Now, line up the take-up lever hole in the lever boss.

Insert the oil wick about 1/2 inch in the bore of the take-up lever. With the oil groove up, insert the take­up lever pin in the lever, making sure the wick is in the groove and press the pin into its hole in the arm. There
should be no end play in the take-up lever after the set screw is securely tightened. Replace the plastic

plug.
Replace presser bar guide and presser bar spring washer

into position. Place presser bar into presser bar roller
bracket with flat on bar to the rear and tighten hex
head screw and set screw securely.

Line up needle hole in the presser foot with the needle
and tighten presser bar guide screw.

Assemble presser spring, presser spring washer and
presser spring regulator screw.

Refer to paragraph on "Presser Bar Guide" for proper
setting of the guide.

Should the alignment test show the main shaft is out of
position, the upper sprocket and handwheel should be
loosened and the shaft moved left or right as the
conditions indicate. Retighten sprocket and handwheel
so that there is no end play in the upper main shaft and

repeat the alignment check.

HANDWHEEL

The handwheel is constructed so as to minimize noise and is therefore isolated from the pulley by shock
mounts. If for any reason the handwheel is disassembled, the following steps should be used for reassembly.

22

HANDWHEEL (CONT.)

1. Using the upper main shaft as a mandrel, assemble the pulley thrust face down so that at least 1 1/2
inches of the shaft protrudes above it. Tighten the two set screws.

2. Place the rubber isolator ring on the pulley face and align holes.

3. Carefully slide handwheel down the shaft to contact the isolator and align the three holes.

4. Three plastic "O" rings are now inserted into their respective holes in the handwheel.

5. The outer isolator rings and cap are assembled.

6. Insert the three screws that are run through the complete assembly and tighten lightly.

7. Loosen the two pulley screws and slowly revolve the whole assembly several times for good alignment.
Now, gradually tighten the three screws, moving from one to the other until all are snug.

8. The assembly should run true as it revolves freely on the shaft. If any sidewise run-out is noted, it can
be corrected by slight changes of screw pressure in the three isolator screws.

CAUTION! When replacing the handwheel assembly on the main shaft, care must be taken not to
damage the oil seal located near the end of the shaft. The surface of the ring should be lightly oiled
and the handwheel worked over the seal gently.
