5.1 DISASSEMBLY AND ASSEMBLY, DAF ENGINE PTO
Disassembling drive sprockets from flywheel
housing
1.
Remove the lower drive sprocket
attachment bolt and remove the sealing
plate on the rear of the sprocket shaft.

Place the flywheel housing under a hand
press and press the sprocket shaft of the
lower drive sprocket out of the flywheel
housing.
Note!
Before disassembling the drive
sprockets, note the mounting
direction in the flywheel housing.
This is to ensure that the
PTO housing fits when the
gearwheels of the drive sprocket of
the PTO housing are assembled.
3.
Remove the drive sprocket with inner race
and shim from the flywheel housing.
4.
Similarly, remove the upper drive sprocket
from the flywheel housing (the attachment
bolt has already been taken out when the
flywheel housing was removed).

If necessary, remove the inner race from the
sprocket shaft.
