    Object Number: 748220  Size: SH

    Notice: Never clamp propeller shaft tubing in a vise. Clamping propeller shaft tubing in a vise could dent or deform the tube, causing an imbalance or unsafe condition. Always clamp on one end of the yokes and support the shaft horizontally.

    Important: Prior to disassembly, mark the positions of the driveshaft components relative to the driveshaft tube. All components must be reassembled in the same relationship to maintain proper balance.

  1. Remove the propeller shaft.
  2. Remove the snap rings.
  3. 2.1. Pinch the ends of the snap ring together with a pair of pliers.
    2.2. If a snap ring does not readily snap out of the groove in the yoke, tap the end of the bearing cup lightly in order to relieve pressure from ring.

  1. Remove the bearing cups from the new universal joint journals.
  2. Coat the needle bearings in the bearing cups with a thin layer of grease that is present on the journal. Use your finger to apply the grease.
  3. Install one bearing cup partway into one side of the yoke.
  4. Turn the yoke ear toward the bottom.
  5. Install the cross into the yoke so that the trunnion seats freely into the bearing cup.

  7. With the trunnion seated in the bearing cup, press the bearing cup into the yoke until it is flush with the yoke ear.
  8. Install the opposite bearing cup partway into the yoke ear.
  9. Make sure that the trunnions are started straight and true into both bearing cups.
  10. Important: If the bearing cup seems to bind or hang-up, stop pressing. Check the needle bearings for misalignment in the bearing cup.

  11. Press the opposite bearing cup into the yoke ear.
  12. • Work the cross all the time.
    • Check for free unbinding movement of the trunnions in the bearing cups.
