1. Apply Polaris Low Temp Grease PN 2870577, or
molybdenum disulfide 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 3.18).
2. Install the camshaft with the lobes facing
downward and the sprocket alignment pin facing
toward intake.
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.
4. Loop the cam chain on the cam sprocket with the
dot on the sprocket facing outward and the
alignment marks parallel with gasket surface.
5. Before positioning the sprocket on the camshaft,
check the position of the cam sprocket alignment
pin. When the cam is positioned properly, the cam
sprocket alignment pin is facing to the intake side.
6. Install the sprocket on the camshaft. Apply Loctite
242 to the cam sprocket bolt and torque to
specifications.
7. Check all cam timing marks to verify proper cam
timing, and install the cam chain tensioner body
with a new gasket.
8. After tensioner installation, rotate engine at least
two revolutions and re-check marks/timing.
