Cam Pulley/Crankshaft/Piston/ Cylinder Block - Honda HRR216PKA Manual

CAM PULLEY/CRANKSHAFT/PISTON/ CYLINDER BLOCK

CAM PULLEY DECOMPRESSION WEIGHT 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 (see "Cam Pulley Installation" below).
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 (see "Cam Pulley
Installation" below).
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.
