Item 11 - Coolant Filter
If the cooling system is protected By a cool 0il filter and conditioner, the filter element should be changed every 500 hours
(15,000 miles). Select the proper coolant filter element in accordance with the instructions given under Engine coolant in
this section. Use a new filter cover gasket when installing the filter element. After replacing the filter and cover gasket,
start the engine and check for leaks.

through each bushing and contact the armature shaft, by removing the pipe plugs on the outside of the motor. The wicks
should be lubricated whenever the starting motor is taken off the engine or disassembled. The Sprag overrunning clutch
drive mechanism should be lubricated with a few drops of light engine oil whenever the starting motor is overhauled.
Item 13 - Air System
Check all of the connections in the air system to be sure they are tight. Check all hoses for punctures or other damage
and replace, if necessary.
