2. Remove the screws that secure the centering housing assembly to the
insertion head, then remove the centering housing assembly.
3. Loosen the screw that secures the tension arm against centering drive
belt and secure the tension arm away from the belt.
4. Loosen the screws that secure the collar clamps on the centering cam
shaft then remove the collar clamps and centering cam shaft assembly.
5. Manually rotate the chains at the chain to chain assembly so the master
links are accessible at the insertion head.
6. Install the chain spreader tool between the idler sprockets in the chain
idler assembly, then extend the chain spreader to relieve tension on the
chains. Removing the top center cover of the machine facilitates ac-
cess to the chain idler assembly.
7. Remove the master links and move the chains back off the upper chain
sprockets.
8. Remove the screws that secure the chain clip guides to the upper idler
shaft then rotate the chain clip guides down.
9. Using the spring hook, remove the springs from the shear blade pins.
10. Hold down the shear blade pins and using the 5/16 allen wrench, rotate
the pinion until the flat surface is positioned toward the driver bodies.
11. Raise each driver body while pushing down on the shear blade pins.
This frees the detents from the tooling and allows the driver bodies to
slide up from the housings.
12. Loosen the two screws that secure the left idler plate tension on the
idler belt. Remove the screw that secures the left spring holder then re-
move the left spring holder and the compression spring.
13. Manually rotate the span axis assembly and move the tooling housings
fully closed.
14. Disconnect the pneumatic lines to the lift cylinders on the tooling hous-
ings.
15. Loosen the set screws that secure the coupling to the lead screw, then
remove the three screws that secure the motor to the housing. Remove
the motor, motor bracket and coupling.
16. Loosen the set screw that secures the collar clamp on the lead screw.
Unscrew the collar clamp from the lead screw while holding the lead
screw so it does not turn.
17. Remove the three button head screws and slide the duplex ball bearing
from the main housing and from the shaft.
18. Disconnect the head drive motor electrical connections.

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.
