Valve Sealing Test; Valve Clearance Adjustment (Intake And Exhaust); Cylinder / Piston Removal And Inspection - Polaris Ranger 500 2x4 2007 Service Manual

6. Place retainer on spring and install valve spring
compressor. Compress spring only enough to allow split
keeper installation to prevent loss of spring tension. Install
split keepers with the gap even on both sides.
7. Repeat procedure for remaining valve.
8. When all valves are installed, tap lightly with soft faced
hammer on the end of the valves to seat the split keepers.

Valve Sealing Test

1. Clean and dry the combustion chamber area.
2. Pour a small amount of clean, high flash point solvent into
the intake port and check for leakage around each intake
valve. The valve seats should hold fluid with no seepage.
3. Repeat for exhaust valves by pouring fluid into exhaust
port.
Valve Clearance Adjustment
(Intake and Exhaust)
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 the valve stem
and adjuster screw(s).
Feeler Gauge for Both Valves
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 500 engines
valves.
NOTE: Both feeler gauges should remain inserted
during adjustment of each exhaust valve.
VALVE CLEARANCE

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.
