Before assembly of components, make sure bearing cups and cones are seated in the housing. A piece of 0.038 mm (.0015 in) shim stock or a standard feeler gauge should not go between the cup or cone and its respective seat.1. Assemble gears (2) and (6), bearing cages (4) and (8) and bearings. Position housing in a vertical position.2. Install two cage bolts evenly spaced in cage (4) and (8). Tighten the bolts to a torque of 2.25 N m (20 lb in). Rotate gears (2) and (6) three revolutions. Tight cage bolts to 4.5 N m (40 lb in).3. Measure gaps (3) and (7) between housing and bearing cages.4. Add shims required to obtain 0.08 0.03 mm (.003 .001 in) end play.5. Measure end play of gears (2) and (6).6. If the end play is less than 0.05 mm (.002 in), add shims. If the end play is greater than 0.11 mm (.004 in), remove shims.7. Apply 7M7260 Liquid Gasket on seal bore surfaces (11) and (15) in the case. Let dry before installing seals.
