CAM PULLEY/CRANKSHAFT/PISTON/ CYLINDER BLOCK

CAM PULLEY DECOMPRESSOR INSPECTION
1. Rotate the flywheel until the cam pulley decompressor
weight slot faces out.
2. Carefully inspect the weight position and confirm that it is
fully retracted. If it is not fully retracted, replace the cam
pulley (P. 10-1).
3. If the weight is fully retracted, operate the decompressor
by very slowly moving it to the opposite end of the slot
and gently releasing. Repeat several times. If the weight
fails to completely return on its own at any time (by spring
force), replace the cam pulley
CAM PULLEY INSTALLATION
1. Turn the crankshaft so that the long crankshaft key
groove (PTO side) faces up as shown.
The two woodruff key grooves will face down.
2. Install the cam pulley on the timing belt so that the cam
pulley alignment marks are in line with the cylinder head
cover mating surface.
Install the cam pulley on the timing belt with care not to
turn the crankshaft.
3. Apply oil to a new O-ring and install it on the cam pulley
shaft.
4. Install the cam pulley shaft in the cylinder block.
5. Hold the cam pulley alignment marks in line with the
cylinder head cover mating surface. Check again that the
crankshaft key groove is facing up.
6. If the key groove is not facing up, repeat the procedure
from step 1.
