Preventive Maintenance
Remove the crankcase breather from the engine and wash the steel mesh pad (element) in fuel oil and dry it with
compressed air. Reinstall the breather assembly.
Clean the breather cap, mounted on the valve rocker cover, in clean fuel oil every time the engine oil is changed.

Inspect the blower screen and gasket assemblies every 1,000 hours or 30,000 miles and, if necessary, clean the screens
in fuel oil and dry them with compressed air.
Reinstall the screen and gasket assemblies with the screen side of the assemblies toward the blower. Inspect for
evidence of blower seal leakage.
Item 14
The electrical starting motor is lubricated at the time of original assembly. Oil can be added to the oil wicks, which
project 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 15
Lubricate the alternator bearings or bushings with 5 or 6
drops of engine oil at the hinge cap oiler every 200 hours
or-6;000 miles.
Some alternators have a built-in supply of grease, while
others use sealed bearings. In these latter two cases,
additional lubrication is not necessary.
The slip rings and brushes of an alternator can be
inspected through the end frame assembly. If the slip rings
are dirty, they should be cleaned with 400 grain or finer
polishing cloth. Never use emery cloth to clean slip rings.
Hold the polishing cloth against the slip rings with the
alternator in operation and blow away all dust after the

cleaning operation.
