REMOVING PLANETARY REDUCTION GEAR6. Remove the bolts securing the ring gear to the housing and, using two forcing screws, remove the ring gear.
REMOVING THE PLANETARY RING GEARPlanetary Reduction Gear Installation
Before installing the reduction gear, inspect all gaskets and replace if damaged.The guide pins, installed for removal, should be used to pilot the reduction gear when it is being installed.Planetary Reduction Gear Disassembly
PREPARING TO DISASSEMBLE PLANETARY REDUCTION GEAR
1-Retainer. 2-Bolts (six). 3-Coupling.1. Remove bolts (2) securing coupling retainer (1) to carrier shaft (4).2. Lift the coupling (3) from the carrier shaft (4).
REMOVING COUPLING
4-Carrier shaft.3. Remove the bolts securing the seal retainer (6) to the cover (7).4. Install two 3/8"-16 (NC) forcing screws in the bearing retainer (6) and separate it from the cover (7).
REMOVING SEAL RETAINER
5-Seals. 6-Bearing retainer. 7-Cover.5. Inspect the seals (5) and O-ring seal for damage or wear and replace as necessary.6. Using a 1H3107 Push Puller, 1H3108 Rods, FT866 Plate and a suitable Hydraulic Pump Group, push the carrier shaft bearing off the shaft and out of the cover.
REMOVING BEARINGS FROM CARRIER SHAFT When the bearings are being removed, it is necessary to change the FT867 Rods as the bearings are pushed off the shaft. As each set of legs reaches its limit of travel, the next longer set of legs must be used. When the FT867 Rods are changed, it is necessary to use 1H3109 Legs, 5F7366 Screw. 5F7353 Washer, 3H466 Nut and an 8B7561 Step Plate with the 1H3108 Push Puller and 7F9540 Hydraulic Puller to push the bearing off the shaft.7. Using a steel bar or rod and a suitable hoist, lift the planet carrier out of the cover.8. Block the planet carrier (9) so the planet gear shaft (8) can be removed.9. Remove the bolts (10) and locks securing the planet gear shafts (8) and remove the shaft.

8-Planet gear shaft. 9-Planet carrier. 10-Bolts (six). 11-Planet gear.10. Remove the planet gears and washers from the carrier.11. Inspect all parts for damage and wear.Planetary Reduction Gear Assembly
1. Install washers, planet gears (11) and planet gear shafts (8) into planet carrier (9). Secure all parts with the locks and bolts (10).2. Position the carrier shaft (4) in a vertical position.3. Lower the reduction gear housing over the carrier shaft before installing the roller bearing races. Heat the taper roller bearings in oil, not to exceed 275° F (135° C), to facilitate installation.4. Install the first tapered roller bearing on the shaft with the small end of the taper upward.5. Install the outward forward bearing race, small end downward. The outer bearing races are a slip fit in the housing.6. Install the spacer for the outer races into the housing.7. Install the spacer for the inner races on the carrier shaft. Lubricate the seal rings and the sealing surface to facilitate installation.8. Install the remaining bearing outer race, tapered roller
