Camshaft Installation - Timing Method 2. Refer to Illustration, Page 3.86
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 3.48).
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 .slo.Q.l.e (TOC ) timing mark
(Top Dead Center) on the flywheel with the notch
in the timing inspection window. Be sure to use
the single TOC mark when insta:ling the cam. Do
not use the advance marks. See III. on next page.
4. Loop the cam chain on the cam sprocket with the
dots on the sprocket facing outward and the
alignment pin notch facing directly upward.
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 directly in line with the
crankshaft/camshaft centerline.
6. Install the sprocket on the camshaft. Apply Loctite
242 to the cam sprocket bolts and torque to
specifications.
7. Apply Loctite 515 or 518 Gasket Eliminator, or 3
Bond 1215 to the camshaft end cap and install
using a new O-Ring.
8. Check all cam timing marks to verify proper cam
timing, and install the cam chain tensioner body
with a new gasket.
9. After tensioner installation, rotate engine at least
two revolutions and re-check marks/timing.
