INSPECTION:
The importance of careful and thorough inspection of all parts cannot be over- stressed. Replacement of all parts showing indication of wear or stress will eliminate costly and avoidable failures at a later date.
BEARINGS
Carefully inspect all rollers and cages for wear, chipping or nicks to deter- mine fitness of bearings for further use.
After inspection, dip bearings in clean light oil and wrap in clean, lintless. cloth or paper to protect them until installed.
Inspect for engraved numbers along outside diameter of bearing cups and cones. Match numbers and bearing components together for reassembly.
HOUSINGS
Inspect housings to be certain they are thoroughly cleaned and that mating sur- faces, bearing bores, etc., are free from nicks or burrs. Check all parts care- fully for evidence of cracks or conditions which would cause subsequent oil leaks or failures.
Bearing cartridges should be inspected for cracks, scoring etc. that may have resulted from wear or improper assembly. If signs of wear are found, replace with new.
OIL SEALS, GASKETS AND RETAINING RINGS
Replacements of all 0-rings, oil seals, gaskets and back-up/retaining rings are more economical when unit is disassembled than to risk premature failure of these parts at a later time. Loss of lubricant through a worn seal can result in failure of other more expensive parts of the assembly. Sealing members. should be handled carefully, particularly when being installed. Cutting, scratching or curling under of lip seal seriously impairs its efficiency. At reassembly, lubricate lips of seal with hydraulic oil or transmission fluid.
SHAFTS
If Magna-Flux process is available, use to check parts. Examine teeth and ground or polished surfaces on all gears and shafts carefully for wear, chip- ping, nicks, cracks or scores. If cracked or show signs where case hardening is worn through, replace with new. Small nicks may be removed with suitable hone. Inspect shaft to make certain they are not sprung, bent or splines twisted and that shafts are true.
CASE PARTS AND MACHINED SURFACES
Inspect bores and surfaces for scratches, wear, grooves and dirt. Remove any scratches and burrs with crocus cloth. Remove foreign matter. Replace any parts that are deeply grooved or scratched, which would affect their operation.
Repair if possible or replace any housings or other case parts that are cracked
