Flywheel and Pilot Bearing Removal
TIMING GEAR ALIGNMENT
If the engine is not being completely
disassembled for overhaul and only the timing
gears are to be removed for replacement, make
sure that the camshaft is set at Top Dead Center
(TDC) for the No. 1 cylinder, before removing the
flywheel. If not, proceed as follows:
1. Using the flywheel turning tool, 9996956, bar
the engine over manually so that the
camshaft TDC mark is between the two lines
on the rear camshaft bearing cap. The
flywheel will be at 0° with the camshaft at
TDC.
2. The timing gears can now be removed. Use
care to not rotate the gears as they are
being removed so that the camshaft and
crankshaft remain in the TDC position.
FLYWHEEL REMOVAL PROCEDURE
The flywheel is heavy. Do NOT attempt to
remove the flywheel without the help of an
assistant or the use of a suitable lifting
device. Failure to heed this warning may
result in severe personal injury and
component damage.
1. Remove the retainer screw and remove the
engine speed sensor from the flywheel
housing.
2. If present, remove the transmission pilot
bearing and set aside.
3. Install two M10x100 screws in holes
opposite each other at the outer perimeter of
the flywheel. These screws are used as
handles to aid removal of the flywheel.

5. While supporting the flywheel, carefully tap
the flywheel, alternating from side to side, to
work it off the aligning dowel pin and remove
it from the crankshaft flange.
