Output Transfer Gears (1) Drive gear, (2) Shims, (3) Cover, (4) Idler gear, (5) Shims, (6) Bearing cage assembly, (7) Lip seal and (8) Lip sealAdjustment Procedure for Bearing End Play
Note: Bearing cups and cones must be seated in the housing before assembling the components. Use 0.038 mm (0.0015 inch) shim stock or a standard feeler gauge.
Assemble gears (1) and (4), bearing cages (3) and (6) and bearings without shims. Position the housing horizontally.
Space two bolts evenly in each cage (3) and (6) and torque to 2.25 N m (20 lb in). Rotate gears (1) and (4) three revolutions and torque cage bolts again to 4.5 N m (40 lb in). Again rotate gears (1) and (4) three revolutions and torque cage bolts to 4.5 N m (40 lb in).
Measure gaps (2) and (5) between the housing and the bearing cages. Measure gaps at each bolts.
Add the two measurements for each bearing cage. Divide the sum for each bearing cage by two. This is the average gap for each bearing cage.
Add 0.18 mm (0.007 inch) to the average gap measurement in order to determine the thickness of the shims.
Measure end play of gears (1) and (4) .
If end play is less than 0.05 mm (0.002 inch), add shims. If end play is greater than 0.11 mm (0.004 inch), remove shims.Note: The output shaft must have a minimum end play of 0.02 mm (0.001 inch).
