Inspection
1. Clean all parts in a solvent tank and dry with com-
pressed air prior to inspecting. Carefully inspect all criti-
cal areas for any surface finish abnormalities: Seal
grooves, bearing grooves, thrust surfaces, rod surface,
housing bore and gear teeth.
2. Inspect thrust washers (304) for rough or worn edges
and surfaces. Measure thickness to make sure it is within
specifications (Not less than 0.092” or 2.34 mm).
3. Inspect wear guide condition and measure thickness
(not less than 0.123” or 3.12 mm).
Assembly
1. Gather all components and tools into one location
before re-assembly. Use cut-away drawing to reference
seal orientations.
