After 100,000 km (60,000 miles) it is advisable to renew the
wheel bearings even if they appear to be serviceable when
examined.
Drive out wheel bearing and shaft sealing ring outwards.
Check seating faces of wheel bearings for traces of slip
on the hub.
Drive in outer ball bearing to fullest extent.
Only use C3 bearings.

Determine distance B.

Measure A = length of spacer sleeve.

To determine thickness of spacer ring C.
Example: A 63.5 mm (2.500")
B 58.6 mm (2.307")

-----------------------------
4.9 mm (0.192")
- D 0.1 mm (0.004")

------------------------------

-C 4.8 mm (0.188")
D recommended end float = 0.05 - 0.1 mm (0.002 - 0.004")
Fit wheel bearing with spacer ring C as calculated and 35 g
(1.2 oz.) Retinax A per wheel beraing.
The space between wheel bearing and shaft sealing ring must
be free of grease. On the other hand the sealing lips
should be packed with Retinax A.
