MAINTENANCE AND LUBRICATION
Oil Change (400/500)
7. Place shop towels beneath the oil filter. Using an oil filter wrench,
turn the filter (1) counterclockwise and remove.
8. Lubricate the gasket on the new filter with a film of new engine
oil. Check to make sure the gasket is in good condition. Also
make sure the gasket from the old filter is not still on the engine.
9. Install the new filter and tighten by hand 1/2 to 3/4 turn after
gasket contacts the engine.
10. Approximately one cup of engine oil
will remain in the crankcase. To
drain, remove the drain plug on the
lower right side of the crankcase.
NOTE: The sealing surfaces on the
drain plug and crankcase should be
clean and free of burrs, nicks or
scratches.
11. Reinstall the drain plug and torque to
14 ft. lbs. (19 Nm).
12. Remove the dipstick (2) and add two quarts (1.9 l) of the
recommended oil. Reinstall the dipstick. NOTE: If the sump is
not drained, add about 1 3/4 quarts initially.
13. Place the gear selector in neutral and set the parking brake.
14. Prime the oil pump using the procedure below. Then stop the
engine and inspect for leaks.
15. Recheck the oil level on the dipstick and add oil as necessary to
bring it to the recommended level on the dipstick.
16. Dispose of used filter and oil properly.

Oil Pump Priming

This priming procedure must be performed whenever the oil hose
connection between the oil tank and pump inlet has been disconnected.
1. Clamp or pinch off the vent line (1)
approximately 2I from the oil tank
(2), between the end of the oil tank
vent fitting and the vent line's
pressure relief slit (3).
2. Run the engine for 10-20 seconds.
3. Remove the vent line clamp. If the
line is bled properly, you should hear a
rush of air, indicating that the line is properly primed and ready for
operation. If you do not hear air, the line has not bled, and you'll
need to repeat the priming procedure.
