Failure to properly assemble parts or failure to follow established procedures can lead to damage of the parts and assembly. To avoid damage to parts, always identify and mark the parts so that they can be installed in the same location. Ensure that gear surfaces align. Never force parts during assembly. |
Note: Replace all seals when you reassemble the gerotor motor. Align the sections of the motor with the marking that was made during the disassembly procedure.
- Clean all parts and inspect all parts. If any parts are worn or damaged, use new Caterpillar parts for replacement.
- Lubricate the seal with clean hydraulic oil.
