Cam Chain/Camshaft Installation
Install the cam chain over the crankshaft.
CAUTION: Serious engine damage may re-
sult if the camshaft is not properly timed to
the crankshaft.
IMPORTANT CAMSHAFT TIMING NOTE: In order to
time the camshaft to the crankshaft, the piston must be
precisely located at Top Dead Center (TDC).
Camshaft Timing
1. Apply Polaris Premium Starter Drive grease to the
camshaft main journals and cam lobes. Lubricate
automatic compression release mechanism with
clean engine oil. (To install the compression
release mechanism, refer to page 3.57).
2. Install the camshaft with the lobes facing
downward and the sprocket alignment pin facing
upward.
3. Disconnect the wire from the cam chain and rotate
the engine to align the single (TDC ) timing mark
(Top Dead Center) on the flywheel with the notch
in the timing inspection window. Be sure to use
the single TDC mark when installing the cam. Do
not use the advance marks. See Ill. on next page.
