General Service Recommendations
There may be more than one way to “disassemble” or “reassemble” a particular part(s),
therefore, it is recommended that the entire procedure be read prior to repair.
IMPORTANT: Read the following before attempting any repairs.
In many cases, disassembly of a sub-assembly may not be necessary until cleaning and
inspection reveals that disassembly is required for replacement of one or more compo-
nents.
Service procedure order in this section is a normal disassembly-reassembly sequence.
It is suggested that the sequence be followed without deviation to assure proper repairs.
When performing partial repairs, follow the instructions to the point where the desired
component can be replaced, then proceed to “reassembly and installation” of that compo-
nent in the reassembly part of this section. Use the “Index” (on back of section divider)
to find correct page number.
Threaded parts are right hand (RH), unless otherwise indicated.
When holding, pressing or driving is required, use soft metal vise jaw protectors or wood
for protection of parts. Use a suitable mandrel (one that will contact only the bearing race)
when pressing or driving bearings.
Whenever compressed air is used to dry a part, verify that no water is present in air line.
