Inspect Parts For Wear
1.
Clean and dry all parts thoroughly before inspection. It
is not necessary to inspect seals. They will be placed as
new items.
2.
Check drive shaft spine for twisted or broken teeth,
check keyed drive shaft for broken or chipped keyway.
No marks or grooves on shaft in seal area, some discolor-
ation of shaft is allowable.
3.
Inspect drive gear shaft and idler gear shafts at bearing
points and seal area for rough surfaces and excessive wear.
4.
Inspect gear face for scoring or excessive wear. If face
edge of gear teeth are sharp, they will mill into the bear-
ing blocks. If wear has occurred, parts are unusable.
5.
Inspect bearing blocks for excessive wear or scoring on
surfaces in contact with gears. Inspect bearings for
excessive wear or scoring.
6.
Inspect area inside gear housing. A clean ”wipe” on
inside surface of intake side is normal. There should not
be excessive wear, deep scratches, or gouges.
