1. Remove tube assembly (1) from the rear of the reduction gear and planetary housing.2. Use a 1/2"-13 NC forged eyebolt, a hoist and a nylon sling as a support for the reduction gear and planetary. The housing of the reduction gear and planetary is sealed with liquid gasket material. 3. Remove twenty-two bolts (2) from the reduction gear and planetary housing (3). Use a soft hammer to make a separation of the reduction gear and planetary and housing (5).4. Use a hoist and sling to pull the reduction gear and planetary off the planetary group sun gear (4) and from the housing (5). Weight of the planetary reduction gear and planetary is approximately 900 lb. (410 kg).Install Reduction Gear And Planetary
Before the installation of the reduction gear and planetary is made put 7M7260 Liquid Gasket Material on metal surfaces that make contact with each other. 1. Use a hoist and sling to install the reduction gear and planetary on guide pins (1) and the planetary group sun gear (2). 2. Fasten reduction gear and planetary housing (4) to housing (3) with bolts (5). 3. Install tube assembly (6) to the rear of the reduction gear and planetary housing.end by: a) install oil filterb) install selector valvec) install oil pumpd) install oil manifoldDisassemble Reduction Gear And Planetary
start by: a) remove reduction gear and planetary1. Remove ten bolts, nuts and lockwashers (1) from the companion flange (2). 2. Remove the companion flange (2) with a hoist. Weight of the companion flange (2) is approximately 200 lb. (90 kg).3. Remove five bolts and a lock (3) that hold the coupling (8) to the carrier shaft (7). 4. Remove washer (4) and gasket (5). Inspect the gasket (5) for damage and make a replacement if it is broken or damaged. 5. Use a hoist to lift the coupling (8) from the carrier shaft (7). Weight of the coupling (8) is approximately 160 lb. (72 kg).6. Inspect the seals (6) for damage and make a replacement if they are broken or damaged.7. Remove fourteen bolts and lockwashers (9) that hold the bearing retainer (12). 8. Install two 3/8"-16 NC forcing screws in the bearing retainer (12) and make a separation from the cover (11) and the bearing race (10).9. Turn the reduction gear and planetary over and make a support with blocks as shown in the illustration. 10. Use tooling (A) and a 8S8033 Electric Hydraulic Pump Group to push the carrier shaft bearing assembly off the carrier shaft (7) and out of the cover (11). 11. Use a steel bar or rod and a hoist to lift the planet carrier (13) out of the cover (11). Weight of planet carrier (13) is approximately 150 lb. (68 kg). 12. Put blocks under the planet carrier (13) so the planet gear shaft (15) can be removed.13. Remove bolts (14) that hold the planet gear shafts (15). Remove the shafts.14. Remove the planet gears (16) from the carrier (13). Inspect all parts for damage
