5. Remove spark plugs using a 5/8” spark plug socket
with an extension.
6. Inspect electrodes for wear and carbon buildup. Look
for a sharp outer edge with no rounding or erosion of
the electrodes.
7. Clean with electrical contact cleaner or a glass bead
spark plug cleaner only. CAUTION: A wire brush or
coated abrasive should not be used.
8. Measure gap with a wire gauge. Adjust gap if
necessary by carefully bending the side electrode.
9. If necessary, replace spark plug with proper type.
CAUTION: Severe engine damage may occur if the
incorrect spark plug is used.
10. Apply anti-seize compound to the spark plug threads.
11. Install spark plugs and torque to specification.
12. Install the plug caps to the appropriate cylinder by
referencing the MAG and PTO spark plug wire decals.
Ensure wires are pushed down all the way so they
engage onto the spark plugs.
13. Reinstall the cargo box access panel.
STEERING
Steering Inspection
The steering components should be checked periodically
for loose fasteners, worn tie rod ends, ball joints and
damage. Also check to make sure all cotter pins are in
place. If cotter pins are removed, they must be replaced.
Replace any worn or damaged steering components.
Steering should move freely through the 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: Check front end alignment whenever
steering components are replaced.
Steering Wheel Freeplay
Check steering wheel for specified freeplay and operation.
1. Position the vehicle on level ground.
2. Lightly turn the steering wheel left and right.
3. There should be 0.8”-1.0” (20-25 mm) of freeplay.
4. If there is excessive freeplay or the steering feels
rough, inspect the following components.
• Tie Rod Ends
• Steering Shaft U-Joints
• Steering Gearbox
Recommended Spark Plug:
Champion RG4YCX
Spark Plug Torque:
7 ft-lbs (10 Nm)
Inspect electrode for wear and buildup
Spark Plug Gap:
0.03" (0.75 mm)
Due to the critical nature of the procedures
outlined in this chapter, Polaris recommends
steering component repair and adjustment be
performed by an authorized Polaris MSD
certified technician.
