J 36850 TRANSJEL™


    Object Number: 20229 Size: SH

    Important: You must assemble the spacer between the two rows of needle bearings. In order to aid in the assembly of the needle bearings, place the spacer and the pinion gear onto the planet pinion gear pin (714).

  1. Install the pinion gear needle bearing spacer (713) onto the planet pinion gear (711).

    2. Object Number: 20230 Size: SH
  2. Place a thrust washer (710) on the bottom of the planet pinion (711) in order to retain the bottom row of needle bearings.
  3. Use J 36850 or equivalent in order to aid in the assembly and in order to keep the needle roller bearings (712) in the race.
  4. Install the needle roller bearings (712) one at a time into the planet pinion (711).

    5. Object Number: 20228 Size: SH
  5. Install the sun gear to final drive carrier thrust bearing (700) onto the final drive carrier (116). Retain the thrust bearing with J 36850 or equivalent.

    6. Important: Assemble the pinion gears (711) in the same direction that you removed the pinion gears in order to prevent noise due to changing the gear wear pattern.

  6. Assemble the pinion gear thrust washers (710) and the planet pinion gears into the final drive carrier (702).
  7. Install the planet pinion gear pins (714) into the final drive carrier (702) in order to retain the planet pinion gears (711).

    8. Object Number: 20227 Size: SH
  8. Install the final drive carrier spiral retaining ring (701) in order to retain the planet pinion gear pins.

    9. Object Number: 20226 Size: SH
  9. Assemble the thrust washers (708) onto the differential side gears (709).
  10. Install the differential side gears into the final drive carrier (702).
  11. Assemble the thrust washers (706) onto the pinion gears (707). Retain the thrust washers with J 36850 or equivalent.
  12. With the thrust washers (706) attached, install the pinion gears (707) into the final drive carrier (702).
  13. Rotate the pinion gears (707) into position, and install the pinion shaf (703) through the final drive carrier (702) and through the pinion gears (707).
  14. Position the pinion shaft (703) in order to allow installation of the retaining pin.
  15. Install the retaining pin (704) through the final drive carrier (702) and through the pinion shaft (703) in order to retain the pinion shaft (703).
