e) Engine Accessories Lubrication.
(1) Alternator.
Most alternators contain sealed bearings and require no periodic lubrication, however, check to
make certain there are no lubrication points on your particular alternator.
(2) Starter.
Most starting motors are lubricated at assembly and should be re-lubricated only when the starter
is removed and disassembled, however, inspect the starter to make certain it has no lubrication
points.
(3) Water Pump.
The water pump is packed at assembly and requires no periodic lubrication. Replace pump if
signs of lubricant leakage are found.
(4) Fan Pulley.
The fan hub is also lubricated at assembly and requires no periodic lubrication. Replace hub if
lubricant is leaking.
