6.4 X-Axis installation
Refer to Figure 5:
1. Move table to extreme left-hand position.
2. Remove jam nut, hand crank, dial nut, dial, dial
holder, bearing retainer ring, bearing flange,
etc.
3. Slide bushing onto lead screw.
4. Slide adaptor onto bushing.
5. Secure adaptor to the end of table with the
existing socket head cap screws.
6. Slide powerfeed onto bushing.
7. Secure powerf eed to adaptor using two socket
head cap screws provided.
6.4.1 Bevel gear
8. Remove protective cap from bevel gear, and
slide bevel gear onto lead screw. Manually
press and turn bevel gear against drive gear to
check for backlash, and make sure they mesh
snugly.
Leave the clearance between the two gears as
small as possible. If there is some clearance
left, place small shims one by one between
bearing and bevel gear until the gears are
properly fitted. Pack the gears with grease
before proceeding.
6.4.2 Dial and hand crank
9. After proper gear clearance has been set, slide
the dial into position to obtain 0.005” spacing
between dial and the face of the powerfeed
(this will prevent chips from entering gear
train.) Use the two solid and two laminated
large shims provided to accomplish the 0.005”
spacing. Use further shims if needed.
10. Install dial nut. Place key in shaft and install
hand crank. Add washer and locking nut, and
tighten locking nut.
13. Place the limit switch over the holes and
secure with two 3/8 x 1” socket head cap
screws provided. See Figure 6. If the actuators
are not symmetrical, grind them to obtain the
proper position.
14. Secure limit switch cord using the provided
clamp. Attach it to the right-hand side of chip
scraper with the screw provided. See Figure 6.
Figure 6
Never change direction of
power feed movement while machine is
operating, or damage to gear may result. Turn
direction control handle to OFF position and
wait for machine to come to a complete stop
before reversing direction.
IMPORTANT: Installing more than one powerfeed
on your machine may reduce table travel. For
example, the track assembly for the Y-Axis
powe rfe ed will pro hib it f ull tra vel of the lo ngit udina l
table on which the X-Axis powerfeed is installed.
These considerations should be carefully made
before installing multiple powerfeeds.
6.4.3 Limit switch
11. Remove the standard travel stops from your
machine. Install the travel stops prov ided with
your powerfeed unit. It is important that these
stops be firmly secured in the table track to
prevent them from sliding loose and causing
the table to travel too far and possibly damage
other parts of the machine. It is recommended
that you either place the standard stop s back
in position to block the new travel stops from
sliding; or drill a hole behind the table edge
and insert a screw through the travel stops
from behind.
12. Loosen and remove the two socket head cap
screws holding the T-shaped table stop
bracket. NOTE: Retain this original bracket
should manual table movement ever be
needed again.
6.5 Y-Axis installation
6.5.1 Y-Axis track
Drill and tap #10-24 holes in the right side of
machine base below the table, for mounting the TWay Track. See Figure 7.
Note: The limit sw itch mounting bracket provided
with your powerfeed is designed for most mounting
situations. However, the casting design of your
particular machine may require modifications to the
bracket system.

6.6.2 Z-Axis powerfeed
Refer to Figure 10:
1. Remove hand crank, clutch insert, dial, dial
nut, dial holder and bearing flange.
2. Install extension shaft by screwing it onto the
table elevating shaft.
Important:
• Shaft end must be against inner ring of
bearing.
• Inner shaft is 16 or 18 threaded UNC.
3. Tighten base to flange, then instal l powerfeed
and tighten it on the flange.
4. Remove protective cover from bevel gear and
install bevel gear. (Note: Do not install the key
yet.) Push and turn the bevel gear by hand to
check for backlash. If necessary, add a few
shims to obtain proper mesh with the drive
gear of the powerfeed unit.
Pack bevel gear with grease. Do not use
silicon-type grease. Replace gear then
push and turn to check again for backlash.
5. Remove the bevel gear. Install key, replace
gear, install dial and tighten dial nut. Add a few
shims if the dial is grinding the gear. Important:
Pack with grease before installing the bevel
gear.
6. Install clutch against bevel gear. Drill through
one hole of 5mm diameter, and drive t he roll
pin into the hole.
Important: Be sure you have followed each
step carefully and correctly before drilling
and installi ng the r oll pin.
Temporaril y install the hand crank and rotate
in clockwise direction to check for proper
shimming and to make sure there is no
binding action. Make any needed
adjustments before installing roll pin.
7. Install the spring and hand crank, and rotate
again to check for proper shimming and
smooth movement. Lubricate the opening in
the hand crank for smooth m ovement on the
shaft. Then tighten washer and screw at the

grounded outlet that looks like the one pictured in
A, Figure 11.
6.7.1 Grounding instructions
1. All Grounded, Cord-connected Tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having
an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a
qualified electrician.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
cond uctor with insulation ha ving an outer surface
that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or
replacement of the electric cord or plug is
necessary, do not connect the equipmentgrounding conductor to a live terminal.
Check with a qualified
electrician or service personnel if the
grounding instructions are not completely
understood, or if in doubt as to whether the
tool is properly grounded. Failure to comply
may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating less than 150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
11. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown
in C if a properly grounded outlet is not available.
The temporary adapter should be used only unt il a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not permitted in Canada. The green-colored rigid ear, lug, and
the like, extending from the adapter must be
connected to a permanent ground such as a
properly grounded outlet box.
Figure 11
6.7.2 Extension Cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. If an extension cord becomes necessary,
make sure the cord rating is suitable for the
amperage listed on the machine’s motor plate. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Use Table 1 as a general guide in choosing the
correct size cord. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier
the cord.
