Start By:a. remove steering clutch hub couplingsb. remove pinion flangesc. remove drive shaft1. Remove the cover for the bevel gear compartment. 2. Remove nuts (1) from the bolts that hold the bevel gear on the shaft. 3. Remove the bolts that hold bearing cages (2) on the right and left sides of the bevel gear shaft. Install two3/8 - 16 NC forcing screws in the bearing cages. Tighten the forcing screws evenly and remove bearing cages (2) and shims. Keep the shims with their respective bearing cages for installation. 4. Remove the bolts that hold the pinion bearing cage assembly to the bevel gear case.5. Install two 3/8 " - 16 NC forcing screws in the pinion bearing cage assembly. Tighten the forcing screws evenly and remove pinion bearing cage assembly (3) and shims. Keep the shims with the pinion bearing cage assembly for installation. 7. Move the bevel gear shaft away from the bevel gear.8. Remove bevel gear (5) and bevel gear shaft (4).9. Remove the bearing cups, O-ring seals and lip-type seals from the two bevel gear bearing cages. 10. Remove the bearing cones from the bevel gear shaft with tooling (A). 11. Remove bolts (7) that hold the retainer on the pinion shaft flange (6). Keep the shims with the retainer for correct installation.
Typical Example12. Remove pinion bearing cage (8) from the pinion with tooling (A). Keep the puller attachment away from the inner bearing cone when tooling (A) is installed.
Typical Example13. Remove the O-ring seal and lip-type seal from pinion bearing cage (8).14. Remove the bearing cups from pinion bearing cage (8).15. Remove inner bearing cone (9) from pinion shaft (10) with tooling (A).Install Bevel Gear And Pinion
1. Lower the temperature of bearing cups (11). Install bearing cups (11) in the pinion bearing cage. 2. Lower the temperature of bearing cups (12). Install bearing cups (12) in bevel gear bearing cages (2). 3. Heat bearing cone (9) to a maximum temperature of 135° C (275°
