1. Put the five O-ring seals in position on surface (1) of the transmission. Put O-ring (2) in position on the transfer gear case.2. Fasten a hoist to the transfer gears. Align the spline teeth on shaft (4) with the spline teeth in the transfer gears. Put transfer gears (3) in position on the transmission, and install the bolts that hold it. 3. Put shaft (5) in position in the transmission input shaft. Make sure the spline teeth are engaged.END BY:a. install transmission and transfer gearsb. install transmission electronic speed sensorDisassemble Transfer Gears
START BY:a. remove transfer gears 1. Remove bolt (1) and retainer (2) that holds yoke (3) in position. Remove the O-ring seal from under the retainer.2. Pull yoke (3) off the spline.3. Remove bolts (4) that hold bearing cage (5) in position on the case.4. Remove bearing cage (5) and the shims from the case. If necessary, use two 1/2"-13 NC forcing screws to remove the bearing cage from the bore in the case. 5. Remove O-ring seal (8) from bearing cage (5).6. Remove lip seal (6) and bearing cup (7) from the bearing cage with tool (A). 7. The weight of gear (9) is 39 kg (85 lb.). Install a 5/8"-11 NC forged eyebolt in the end of gear (9) as shown, and fasten a hoist to it.8. Remove gear (9) from the case, and remove the eyebolt from it. 9. Use tooling (B) as shown, and remove the bearings from both sides of gear (9). 10. Remove bearing cup (10) from the case. 11. The weight of bearing cage (12) is 30 kg (65 lb.). Use two persons when removing it from the case. Remove bolts (11) and bearing cage (12) from the case. If necessary, use two 1/2"-13 NC forcing screws at location (X) to remove the cage from the case. Remove the shims from between the cage and case. 12. Remove the bolt and clamp (16) which support tube assembly (14). Loosen fitting (15) and the end of the tube assembly. Remove the tube assembly and fitting.13. Remove bearing cone (13) from bearing cage (12) with tool (A). 14. Remove gear (17) from the case. 15. Remove the bearings from both sides of gear (17) with tooling (B). 16. Remove bearing cone (18) from the case with tool (A).Assemble Transfer Gears
1. Lower the temperature of bearing cup (2). Install it in case (1) with tool (A) until it is against the bottom of the counterbore. 2. Heat two bearing cones (3) to a temperature of 135°C (275°F). Install a bearing cone on each side of output gear (4). Make sure the bearing cones are against the shoulders of the output gear after installation.3. Install output gear (4) in the case with lower bearing cone (3) in location on bearing cup (2). 4. Lower the temperature of bearing cup (6). Install bearing cup (6) in bearing cage (5) with tool (A) until it is against the bottom of the counterbore.5. Install tube assembly
