The NDR38 DISC 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)
counterclockwise (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, checking 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):

(L).

in counterclockwise to rise the sliding.
