Drive Shafts
Removal
1. Support the drive shaft being removed so it does not fall
when disconnected. If removing the coupling shaft or the
forward slip shaft, support the other shaft also.
2. If removing the coupling shaft, free its bearing from the
frame by removing two bolts, two locknuts, and four
washers.
3. Remove the bolts from the bearing cap on each end of
the drive line. Note the lengths of the bolts and if they
have lockwashers. Remove the drive line.
Installation
1. For any drive shaft which has mating marks (arrows),
align these mating marks to ensure proper phasing of
coupler yokes.
2. Position the drive shaft between the couplers on the two
components it is joining.
3. For the coupling shaft, secure its bearing to the frame
with bolts, locknuts, and washers.
4. Secure the drive shaft to the coupler with bolts. Torque
the bolts to 110 to 120 lb-ft (149 to 163 Nm).
Lubrication
The drive line slip joints require lubrication. Refer to
Lubrication, page 9-1.
CAUTION
Do not disassemble drive lines when removing them from
the crane. Dirt can enter the spline and cannot be purged.
In addition, the drive lines are assembled in a specific
orientation when manufactured and can easily be
incorrectly reassembled.
