c. General Repair Precautions
1. To facilitate repair of the pump and before any work
is done, read and understand all of the steps used in
the disassembly and assembly instructions.
2. Perform procedures in a clean area. It is important to
service hydraulic equipment in as clean an
environment as possible.
3. If it becomes necessary to pry sections apart, be
extremely careful to avoid damaging the finely
machined surfaces. Excessive force used while
prying can result in misalignment and serious
damage to parts.
4. Match-mark the exterior surfaces of any housings
before separating the components. Use the marks to
return components to their original locations during
assembly.
5. Gears are closely matched sets that wear in
together. Keep gears together as sets when
removing them from a unit. Handle gears with care
to avoid damaging the journals or teeth. Avoid
touching gear journals. Always replace matched
parts as a set.
6. To help prevent damage, DO NOT grip machined
surfaces in a vise.
7. If parts are difficult to fit together during assembly,
tap gently with a soft hammer. NEVER use an iron or
steel hammer to tap parts.
8. NEVER hammer bushings into bores. Use an arbor
press and bushing drivers of appropriate sizes to
install bushings.
