REPAIR AND REPLACEMENT PROCEDURES
(Sheet 3 of 3)
Packing seals and O-rings (preformed packings) should always be replaced if they are removed from the mated part. To prevent leaks, put a coating of the same
lubricant being sealed on seals before putting them on the part.
Always use the tools listed in the manual to work on gears. Always watch for damaged or worn teeth on gears.
Burs and rough spots should be removed with a honing stone or crocus cloth before putting gear in place. Lubricate mating surfaces before pressing gears on
If a shaft does not come out easily, check that all nuts and capscrews have been removed. See if other parts are in the way before using force.
Shafts fitted to tapered splines should be very tight. If shafts are not tight, disassemble and check tapered splines. Discard parts that are worn. Make sure tapered
splines are clean, dry, and free of burs before putting them in place. Press mating parts together tightly.
Clean off rust compound from all machined surfaces of new parts.
Replace worn, damaged, or defective parts with new parts.
