The WR hubs are easy to maintain. To do it, proceed as follows:
FRONT HUB
The front hub does not require any particular maintenance.
For any extraordinary maintenance and replacement of bearings,
follow these simple steps:
• Remove the contact item (A) (Fig. 1)
• On the same side from which you removed the contact item,
insert a 12mm Allen wrench (M) on the hub pin and, using a
classic 17mm wrench (N), unscrew the contact item (B) counter-
clockwise (Fig. 2)
• Remove the axle from the side of the disc brake.
Once the axle has been removed, you can replace the bearings:
• Use a special puller for 17mm holes and remove both bearings (S)
from their seat (Fig. 3)
Once these have been replaced, proceed fitting the new bearings:
• Using a special tool, insert both new bearings in their seat, che-
cking the correct smoothness.
• Insert the hub axel (C) again and tighten the contact item (B) with
the 17mm wrench (N) at the tightening torque of 15Nm. (Fig. 2)
• If necessary adjust the hub by working on the ring (F) (Pic. 2):
• Unlock the grub screw (I) with a allen wrentch 2mm (L).
• Turn the ring in clock sense to drop the sliding, and in counter-
clockwise to rise the sliding.
• Lock the screw (I).
• Check the sliding of the wheel.
Please check that the hub is correctly tightened and closed, fai-
lure to do so could lead to a serious or fatal accident.
