GENERAL INFORMATION
EXHAUST VALVE
CLEARANCE ADJUSTMENT
Feeler Gauge for Both Valves
NOTE: The exhaust valves share a common rocker
arm, and must be adjusted using two feeler gauges.
1. Insert .006 feeler gauge(s) between end of
exhaust valve stem and adjuster screw(s).
2. Loosen locknut(s) and turn adjuster screw(s) until
there is a slight drag on feeler gauge(s). The
Valve/Clutch Adjuster Tool (PA- -44689) can be
used to adjust the 425/500 engines valves.
NOTE: Both feeler gauges should remain
inserted during adjustment of each valve.
EXHAUST VALVE CLEARANCE
.006² (.15 mm)
3. When clearance is correct, hold adjuster screw
and tighten locknut securely
4. Re-check the valve clearance.
5. Repeat adjustment procedure if necessary until
clearance is correct with locknut secured.
STEERING
The steering components should be checked
periodically for loose fasteners, worn tie rod ends, and
damage. Also check to make sure all cotter pins are
in place. If cotter pins are removed, they must not be
re-used. Always use new cotter pins.
Replace any worn or damaged steering components.
Steering should move freely through entire range of
travel without binding. Check routing of all cables,
hoses, and wiring to be sure the steering mechanism
is not restricted or limited. NOTE: Whenever steering
2.28
components are replaced, check front end alignment.
Use only genuine Polaris parts.
500 Engine
Due to the critical nature of the procedures out-
lined in this chapter, Polaris recommends
steering component repair and adjustment be
performed by an authorized Polaris MSD- -certi-
fied technician when replacing worn or dam-
aged steering parts. Use only genuine Polaris
replacement parts.
One of two methods can be used to measure toe
alignment. The string method and the chalk method.
If adjustment is required, refer to following pages for
procedure.
