Service Standards for Replacing Worn Parts
NOTE:
When parts exceed the standard, replace them. When there is conspicuous surface
damage, it is always safer to replace parts, whether standards are exceeded or not.
Inspect O-rings and oil seals very carefully for cuts, nicks, brittleness, softness or any other type of
damage or distortion, before final reassembly if any must be reused.
