DANGER:
THE PROHIBITED SOLVENTS ARE:
CHLORINATED SOLVENT
(TRICHLORETHYLENE,TRICHLOROETHANE) WHICH
BECOMES ACID
FUEL-OIL (EVAPORATES TOO SLOWLY)
GASOLINE CONTAINING LEAD
BENZINE (TOXIC)
After cleaning ensure that the bearing becomes perfectly
dry.
Fill the bearing with the new grease.
Re-assemble the cage and the parts, which have been
dismantled, filling them with grease (2/3 of the empty
spaces must be filled with new grease)
Use a grease pump to complete the bearing lubrication
(while machine running)
5.3.3 Cleaning bearings assembly area
Bearing life is directly impacted by the cleanliness of the
lubricant. The dirt must not enter or pollute the bearings.
Excess of grease must be removed before operation in
order to avoid pollution of the environment as well as the
alternator
Periodically:
clean the labyrinth seals outside face. Remove the excess
of grease which may appears onto the shaft.
Remove the excess of dry old grease from the bearing
exhaust channel (use a clean blade)
After removing the old grease check that a small fresh
volume of grease will plug the exhaust channel (to avoid
pollution coming back to the bearing)
5.3.4 Bearing removal
The inner bearing race is mounted, shrunk onto the shaft.
The outer bearing race is free, or slightly tightened, on the
hub (depending on the type of bearing). To remove the
bearing from the shaft, it is necessary to use a dedicated
hub-puller to avoid damaging the surface of the shaft.
Typical bearing drawing assembly is joined in chapter 10
CAUTION:
CLEANLINESS IS IMPERATIVE
NOTE:
Heat the bearing during the pulling operation is
recommended to prevent the shaft from being scored.
