2. Apply silicone RTV gasket material to spider flange at hub mounting face. Use silicone RTV gasket application procedures as follows: a. Remove dirt, grease or moisture from both mating surfaces.b. Dry both of the surfaces.
Minor concentrations of acetic acid vapor may be produced during application of silicone RTV. Adequate ventilation should be provided when silicone RTV is applied in confined areas.Eye contact with these silicone RTV gasket materials may cause irritation. If contact with eyes takes place, flush eyes with water for 15 minutes and have eyes examined by a doctor.
c. Apply silicone RTV in a continuous thin bead, 2 to 3 mm (.09 to .12 in) diameter, completely around flange surface and around the inner edge of all fastener holes. Use the typical application pattern (1) shown to assure complete sealing.d. Assemble the components immediately to permit silicone RTV gasket material to spread evenly. Failure to use appropriate gasket material will cause axle to leak. 3. Start the spider and pinion assembly (2) into the wheel hub, aligning teeth of planet gears with the teeth of sun gear and ring gear.4. Align the match marks on the spider flange and the wheel hub as previously marked at disassembly.5. Align hub holes with spider holes and push spider assembly against hub.6. Install spider lockwashers and bolts (3), and tighten evenly to specified torque.7. Rotate the wheel end to position the fill/level plug (4) at the horizontal centerline of the axle. If vehicle is on blocks, lower the vehicle until wheel is on the ground or until axle is level again.8. Remove the fill/level plug from the flange of the planetary spider assembly.Reference: For correct type of lubricant and capacities, see the RR-250 Operation and Maintenance Guide, Form No. KEBU0637, or the SS-250 Operation and Maintenance Guide, Form No. KEBU0636.9. Fill the wheel end with the correct lubricant until it is level with the fill hole. Wait for lube to distribute evenly throughout planetary. Check lube level and add more lube if necessary.10. Make sure magnetic fill/level plug has been cleaned of any metal particles. Replace plug and tighten securely.End By: a. install wheelDisassemble Planetary Spider Assembly
Start By: a. remove planetary spider assembly1. Remove the setscrews holding the planet pins in the spider. Setscrews are located at the small diameter ends of the planet pins. 2. Support spider assembly in a press, flange side down, and block up as required. To avoid damaging the pins, place a block of wood under the press to cushion the fall of the pins as they are pressed out. If a press is not available, use a brass drift and mallet to tap out the pins.
Do not strike the planet pins directly with a steel hammer or personal injury from chips or splinters may result.
3. Press the planet pins (3) out through the spider (1) and planet gears (2). 4. Remove the planet gears (2) and their respective thrust washers (4). Thrust washers are designed for opposite sides of planet gears and
