19. Loosen the two set screws in the drive motor coupling on the pinion
shaft side of the coupling.
20. Remove the four cap screws that secure the drive motor mounting plate
to the housing and remove the drive motor, coupling and mounting
plate as a unit.
21. Remove the three button head screws that secure the drive pinion shaft
ball bearing clamp to the right side of the housing.
22. Loosen the two set screws that secure the left side ball bearing clamp to
the pinion drive shaft.
23. At the left side of the housing, gently tap the end of the pinion drive
shaft until the ball bearing clamp on the right side of the housing be-
gins to move out of the housing.
24. Ease the pinion drive shaft and all the attached components through the
right side housing ball bearing clamp mounting hole.
25. Loosen the set screws that secure the upper and lower shafts.
NOTE
The lower shaft set screws are located under the main housing and are
not visible from the front of the insertion head.
26. Support the tooling housings then slide the upper and lower shafts to
the left and remove the shafts.
27. Remove the tooling housings and lead screw as a unit.
28. Manually rotate the lead screw to move the tooling housings apart
thereby providing access to the screws that secure the flanged bush-
ings to the tooling housings.
29. Remove the screws that secure the flanged bushings to the tooling
housings.
End of procedure.
Ball Bushing Shaft Checks
The following procedure describes checks to be made to the ball bushing
shafts.
1. Check both upper and lower shafts for any scoring.
2. If the shafts are loose or badly scored, replace both ball bushings and
shafts.

Ball Bushing Preload Adjustment
The following procedure describes adjustment to be made to the shaft to
bushing clearance. Slide the ball bushing shafts through the bushings. If the
shafts pass through the bushings with any grinding or binding, bushing re-
placement is necessary. When replacing the upper bushings, no preload ad-
justment is necessary. Simply press out the bushings and replace them.
Replace the lower bushings as follows.
1. Insert the shaft through the two ball bushings.
2. Tighten the preload set screw until drag is felt when sliding the shaft
back and forth.
3. Loosen the set screw until the drag is just eliminated.
4. Repeat the procedure for the second ball bushing.
Lead Screw Flanged Bushing Checks
The following procedure describes checks to be made to the lead screw
flanged bushings.
1. Thread the lead screw into the flanged bushing.
2. Clamp the housing, which supports the sleeve, so the lead screw is in a
vertical position. Hold the upper end of the lead screw shaft and pull
upwards. If any movement is detected in the vertical direction, the
sleeve must be replaced. Side to side play in this vertical position does
not indicate a bad flanged bushing.
Inside Former Check
The following procedure describes the check to be made to the inside form-
ers.
1. Remove the kick out arm assemblies from the tooling housings.
2. Clean the area between the housing and kick out arms where they pivot
then check the inside former and O-rings for wear and replace if neces-
sary.
3. Lubricate the cam surfaces and pivot hole of the kick out arm assembly
with Kluber Syntheso D32. Install the kick out arm assemblies. En-
sure that each arm is free to pivot and that the screw is tightened
against the dowel pin.

CAUTION
Failure to use Kluber Syntheso D32 oil as stated in our machine
maintenance schedules leads to reduced tooling life and/or failure.
Syntheso D32 is a special blend specifically designed for high speed
moving and mating metal parts. No other oil is recommended.
Shear Block Check
The following procedure describes the check to be made to the shear blocks.
1. Remove the shear blocks from the kick out arm assemblies.
2. Check the shear block for wear and replace if necessary.
3. Using Loctite 222 on the threads of the screws, install the shear blocks
and secure in position with the screws.
End of procedure.
