GEAR HOUSING – SPINDLE SHAFT
Spindle shaft
The spindle shaft is driven by the intermediate shaft which in turn is dri-
ven by the electric motor. The complete spindle shaft contains a number of
moving parts, including axially moving gear wheels for the gear function.
Incorrect handling of the machine could, however, cause the actual shaft to
bend, or damage the tool bracket. In these cases, all units on the spindle shaft
must be removed to replace the actual shaft.
Service work
The complete intermediate shaft must always be removed first.
Only when the shaft is released from the components on this can the actual
spindle shaft be removed from the gear housing.
Note – images: Most images in this chapter are photographed with the
shaft removed for the sake of illustration.
The transmission in this machine is rarely the cause of any problems.
All work on the spindle shaft must be performed inside the gear housing.
Removing the spindle shaft
Remove the circlip.
Lift off the gear wheel.
Remove the gear knob as follows: Loosen
the lock screw. Press the gear knob out of
the housing. Remove the gear selector.
IMPORTANT – thread locking
When refitting the locking screw, thread
locker must be applied to the threads,
Loctite 243.
Lubricate the O-ring.
Lift off the gear wheel.
