I changed the head gasket and now I need to set the cams in the right way. If you know how to do that please tell me how to do that and what do the little marks on the gears mean?2003 polaris predator 500 cams?
This should answer your question
1. Remove ignition timing inspection plug from recoil
housing. To position crankshaft at Top Dead Center
(TDC) on the compression stroke.
2. Rotate engine slowly in the direction of rotation
watching intake valves open and start to close.
3. Continue to rotate engine slowly, watching for the
cam shaft sprocket marks and the %26quot;T%26quot; mark in the
timing inspection hole.
4. Align the %26quot;T%26quot; (TDC) mark on flywheel with the
indent in the inspection hole and the cam
sprockets marks (facing upward) aligned with the
dots at the 12 o'clock and 9 o'clock positions.
NOTE:
The cam lobes should be laying flat and
the valves have clearance at thispoint.
Place the thrust washer on to the crankshaft with
the chamfered side in ward. Install the crankshaft
cam sprocket onto the shaft. Note the double
spline for ease of installation. The alignment mark
should face outward.
Position the chain for correct timing by aligning the bottom cam timing
mark with the brass colored bottom chain link.
Keep tension on the chain so as to not lose chain
alignment at the crankshaft sprocket during cam
installation.
5. Next, install the intake cam, positioning the upper
cam chain for correct timing by aligning the
remaining brass colored chain link with the 12
o'clockdotonthecamsprocket. Timing is in phase
when all three brass colored cam chain links align
with all three sprocket timing marks and the
secondary cam gear marks are at approximately
the 9 o'clock position,with the exhaust cam timing
mark slightly advanced.
NOTE: Failure to align marks in this fashion will
cause valve---to---piston interference, resulting in engine damage
