Removing the bearings

REMOVING THE BEARINGS

• Separate Fig. I the hub from the stub axle :
  • extractor FACOM U53 T2,
  • bridge FACOM U53 S2,
  • adaptor 8.0520 H2.
• Remove Fig. II, the bearings (3) and (5). The oil seals will be removed at the same time. Whenever the bearings are removed it is essential to renew the bearings and the seals.
• Retrieve the spacer (4) and the adjusting shims (7).
• Clean all the parts.

REFITTING THE BEARINGS

• Fit the outer bearing tracks (3) and (5) Fig. II and III into the stub axle.

  Use the adaptor 8.0531 A2 and the mandrel A3 Fig. III

ADJUSTING THE END FLOAT

The bearing end float must be 0,025 to 0,10 mm
Incorrect end float will quickly destroy the bearings.

Preparation

• Place in the inner end of the stub axle :
  • the inner bearing assembly (6),
  • the adaptor 8.0531 A1 and the threaded rod B1.
• Place in the outer end :
  • the spacer (4) between the shims (7) centred by the adaptor 8.0531 A1,
  • the inner bearing assembly (2),
  • the adaptor 8.0531 A2 and the ring B2.
• Tighten the nut (1) to 1 m.daN (7 lbf ft).
• Rotate the assembly to settle the bearings.
