Maintenance

improper alignment in the following steps.

6. Install bolts loosely in the gearbox and push the drive

dogs of each coupler together to check for proper

alignment.

7. Align the gearbox so that the sides of each coupler

are parallel with each other, and then check the height

difference between the two couplers. Check the

misalignment with a straight edge and a feeler gauge,

and shim as needed (use optional shims in addition to

the 14ga shims installed on the machine).

8. After the correct shims are installed hand tighten the

gearbox bolts (M16) in a star pattern and recheck to

make sure the couplers are still aligned. Unit requires

763434 (5/8 washer) and 726702 (5/8 Lock Washer)

Note: if no shims are needed, install 2-1/2” washers (in
addition to 763434) to prevent dust from entering the holes.

9. Check the coupler a second time. If it is still aligned,

torque the gearbox bolts in a star pattern to 120 lb-ft.

10.Insert the spider into the coupling and insert the drive

dogs into the coupling leaving an equal gap between

them (~0.020”).

11.Check alignment and torque the locking bolt (3/8 HEX)

to 45 lb-ft with “Blue” med strength Loctite.
