REMOVING EXISTING DRIVE
CAUTION
MAKE SURE ELECTRICAL POWER IS TURNED OFF.
1. Disconnect electrical wiring to drive unit.
2. Refer to page 2-4 of Service Manual for Modular
Dishwashers, for instructions on removing existing drive
unit.
3. Remove bolts and nuts securing drive to table and lower
drive unit to floor. Remove existing drive unit.
4. Remove both front and back drive supports (W-2-14148).
(See fig 1.)
INDEX
5. Using a grinder with a cutting disc remove the existing
chain guide (3/16" x 1/2" strip) welded outside the
tables. (See fig 2.)
INSTALLING NEW DRIVE UNIT
1. Determine if machine has clockwise or counter-clockwise
conveyor. Follow directions in fig 3 for drilling holes in
clockwise conveyor, fig 3A for counterclockwise conveyor.

Figure 4. Threading Rail Studs
3. Cut off the excess amount of each stud flush with the
nut. (See fig 8.) This must be done to provide clearance
for drive arm assembly (Item 80 on attached exploded
view).
2. Run additional threads on all four of the existing rail
studs AS CLOSE as possible to the bottom of the
table. Use the 3/8"-16 thread die (W-0-95576) provided
in the kit. A large adjustable pliers or pipe wrench can
be used to run the thread die up the studs. (See fig 4.)
(A) CLOCKWISE MACHINE
Pack a large amount of silicons sealant around
the 2 studs on the left. Place a split lockwasher
and nut on each stud and securely tighten.
(B) COUNTERCLOCKWISE MACHINE
Pack a large amount of silicone sealant around
the 2 studs on the right. Place a split
lockwasher and nut on each stud and securely
tighten.

4. Remove front and rear covers of type "D " drive and
place on lifting device. (See fig 6.)
5. Remove drive pawl assembly (Item 83 on attached
exploded view). (See fig 6.)

6. Lift new drive part way into place. (See fig 7.)
7. Reconnect safety limit switch (Item 10 of attached
exploded view). Connect to COMMON and N.O.
terminals. If flexible conduit is not long enough. you may
need a new section of 3/8" flexible waterproof conduit.
CAUTION
9. Attach drive arm pivot weldment (Item 7 of attached
exploded view) to front of table. Be sure Item 46 of
attached exploded view is placed under Item 7 before
attaching lockwashers and nuts. Apply liberal amount of
silicone sealant around top of hole before inserting bolts.
10. Plug unused hole with 3/8" x 16 truss head bolt. Apply
silicone sealant around hole before inserting.
BE SURE FLEXIBLE CONDUIT IS RETAINED BY BOTH
CLAMPS (ITEM 19 ON EXPLODED VIEW). THIS HOLDS
CONDUIT AWAY FROM GEAR REDUCER CRANK.
Figure 7. Lifting New Drive Into Place
8. Lift drive up to the table and fasten, using 3/8"-16 and
1/4"-20 S/S truss head screws as shown. Always apply a
liberal amount of silicone sealant around the hole before
inserting the truss head bolt. (See fig 8.)
11. Reinstall drive pawl assembly. (See fig 9.)
Figure 9. Reinstalling Drive Pawl Assy
12. Check for clearance between drive arm assembly (Item 80
of exploded view) and drive arm slide (Item 53 of exploded
view). You should be able to pass a business card (0.020
shim) between the arm and slide. (See fig 10.) To adjust,
place a shim on one side or the other of the drive arm pivot
weldment. (See fig 11.) Placing a shim as shown in fig. 11
will increase the clearance. Placing a shim on the other side
will decrease the clear-ance (hack saw blade(s) work very
well as shims).

accomodate heavier 1/2 H.P. motor of type "D" drive.
The kit contains overloads for both old and new style
control boxes and for both 208-230V and 460-480V, 3
Phase, power connections. Old style control boxes used
2 overloads, new style use 3. Select and change the
proper overload from the chart listed below. Use the
extra overloads for other service work.
Figure 12. Checking Drive Pawl to Roller Clearance
208-230 Volts Use 2 E34 Overloads
OLD STYLE CONTROL BOX
440-480 Volts Use 2 E26 Overloads
NEW STYLE CONTROL BOX
208-230 Volts Use 3 N-17 Overloads
440-480 Volts Use 3 N-11 Overloads
ADJUSTMENTS
1. Operate conveyor. When fully retracted, drive pawl
assembly (Item 83) wilt be approximately 1/2 inch in
back of roller. (See fig 12.)
The stroke of the drive is fixed at 6 inches. The
connecting rod (item 64, page 7) should be adjust ed so
that the drive arm assembly (item 80, page 7) clears
both sides of the drive equally. (See fig. 13.)
2. Setting Conveyor Overload Switch.
The following test should be performed on every
Flight-A-Round dishwasher service call, even when
there is no apparent conveyor problem. Machine
damage due to improper setting of the overload safety
switch adjustment nut is not covered under warranty.
Misaligned tracks or other binds in the track wilt make
the overload switch ineffective. Be sure conveyor
flows freely around the table before setting the
switch. Usually, conveyor misalignments or binds can
be easily located. In the event that they cannot,
remove the entire conveyor from the machine. Then
manually push a 4 foot section of conveyor around
the table to locate the obstruction. Fig 14 shows the
side of the drive with the cover removed, exposing the
compression springs.

Use a testing scale for conveyor overload safety

Testing Conveyor Overload Switch Setting
switch (Pan No. W-0-18410) or a 50 pound fish scale.
To hold the testing scale. Insert a 9-inch piece of 1/2
inch pipe or thinwall through the eyelet of the scale.
Test and adjust the overload safety switch setting as
follows:
(A) Press conveyor START switch.
(B) Position yourself at a curved section of the
Flight-A-Round table, preferably the curve
farthest from the conveyor drive assembly.
nut or loosen the spring compression nuts
until the conveyor stops. (Loosen both
nuts evenly.) Turn clockwise to increase
tension.
(F) Recheck overload safety switch setting and
repeat adjustment until conveyor stops
within the 40 to 50 pound ran ge. Lock the
adjustment nuts in position with the
lockouts. Recheck safety switch setting
after the locknuts have been tight-ened and
readjust if necessary.
(C) With conveyor running, insert hook end of
the scale around the last outboard spacer of
a carrier as shown in fig 15.
(CW Shown)
(D) Pull back on scale, noting scale reading.
Conveyor must stop when scale reading is
between 40 and 50 pounds with conveyor
empty.
FINAL ASSEMBLY
1. Install all covers and check all screws for proper
tightness.
2. Install 4-Inch section of carrier link shield over spot
vacated by type "C" drive cover. You will probably have
to customize here. Usually the carrier shields on both
sides of the drive must be removed, cut back and new
mounting holes drilled. This will provide a mounting
surface for the new shield. BE SURE TO RADIUS ALL
SHARP CORNERS. (See fig 16.)
3. If machine is equipped with one man cost control, it will
probably be necessary to reset the cost control timer.
Refer to Section 13-37 of your Service Manual for
Modular Dishwashers for complete recalibration
instructions.
