Countershaft Assembly: Inspection
- Clean all parts with solvent. Dry parts using compressed air. Inspect bearings, races, thrust bearing and race, drive pinion and gears for wear or damage. Replace components as necessary.
- Measure inside diameter of planetary sun gear bushing. Standard diameter should be 1.173-1.174" (29.80-29.83 mm). Maximum inside diameter is 1.176" (29.87 mm). If clearance exceeds specification, replace planetary sun gear.
- Measure planetary pinion gear thrust clearance. Standard clearance should be .008-.020" (.20-.50 mm). See Figure. If clearance exceeds specification, replace planetary gear assembly.
