CAUTION
When special measurements for shimming are made on parts or as-
semblies prior to their installation in the next higher assembly, these
parts shall be tagged as measured components of the higher assem-
bly (clutch serial number) and kept with that assembly. If annular ball
bearing (25) is replaced all measurements which included that part
shall be repeated using the new bearing.
CAUTION
Do not oversize seal. If seal becomes oversized, remove seal and re-
place with a new one. Once seal has been properly formed apply a
small amount of Mobilgrease28 to seal surfaces and install rotating
flange (17) into seal to retain its shape.
CAUTION
Use caution not to damage plain encased seals during disassembly
NOTE
Ensure that all clutch parts and assembly tools are cleaned prior to assem-
bly. Wipe all surfaces with a clean lint free cloth.
NOTE
Lightly coat all surfaces of shafts that mate with seals and packings, with
Mobilgrease28.
10.1 Gently wipe down plain encased seal (18) using a clean, lint free cloth or cotton swab. Encased seals
take firm set after being formed. If deformed during the cleaning process replace seal. Once deformed from
its original set do not attempt to reform seal.
