Inspection and General Instructions for Reassembly
Before reassembling the transmission, the individual parts should be carefully checked to eliminate those damaged from previous
service. This inspection procedure should be carefully followed to insure the maximum of wear life from the rebuilt unit.
The cost of a new part is generally a small fraction of the total cost of downtime and labor, should the use of a questionable part
make additional repairs necessary before the next regularly scheduled overhaul.
Recommended inspection procedures are set forth in the check list which follows:
Bearings
•
Wash all bearings in clean solvent. Check balls, rolls, and races for pits and spalled areas. Check the bearing shields for
damage. Replace bearings which are pitted, spalled, or damaged.
•
Lubricate bearings and check for axial and radial clearances. Replace the bearings with excessive clearances.
•
Check fits of the bearings in the case bores. If the outer races turn freely in the bores, the case should be replaced.
Gears
•
Check the operating gear teeth for pitting on the tooth faces. Gears with pitted teeth should be replaced.
•
Check all engaging gear teeth both internal and external. Gears with teeth worn, tapered, or reduced in length from clash-
ing in shifting should be relpaced.
•
Check the radial clearance of the bushed gear. If excessive radial clearance is found, replace the bushing.
Splines
•
Check the splines on all the shafts for wear. If sliding gears or companion flanges have worn into the sides of the splines,
shafts, or gears they should be replaced.
Gray Iron Parts
•
Check all gray iron parts for cracks and breaks. Replace or repair parts found to be damaged. Heavy castings may be
welded or brazed providing the cracks do not extend into the bearing bores or bolting surfaces.
