Countershaft Assembly: Inspection

  1. 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.
  2. 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.
  3. 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.
