A wheel with play, or one that turns roughly, damages the brakes, the drive and the handling. This kit groups the bearings and seals needed to rebuild the rear wheel, with the spacers when the model needs them.

Specifications

• Brand: PROX
• Manufacturer part number: 23.S114058

When to replace it?

• Side play when you rock the wheel top and bottom.
• Wheel turning roughly or unevenly, bearing noise.
• Damaged seals, rust or water in the hub.

Check the wheels for play every time you wash the bike. As a Cross-Mania guideline: replace every 40 to 60 hours of racing or muddy riding, about once a year for leisure riding, and straight away as soon as play appears.

Fitting tips

1. Remove the old bearings with a puller or a bearing drift, without damaging the hub bore.
2. Clean the hub, put the new bearings in the freezer and press them in on the outer race only.
3. Refit the central spacer between the bearings: without it, the bearings get crushed when the axle is tightened.
4. Fit the seals squarely, lips packed with grease.
5. Grease the wheel axle and tighten it to the manufacturer's torque, then check that the wheel turns freely.

Frequently asked questions

What does the kit contain?
The bearings and oil seals of the rear wheel, plus the spacers or collars when the model needs them. Compare with the photo and your original parts if in doubt.

Should both bearings be changed?
Yes: they wear together. Changing only one bearing brings the play back very quickly.
