Compact bearings
– every two years –
Compact bearings are recognizable by
their cylindrical cap shape.
Compact bearings comply with the latest
durability requirements. They are mainte
nancefree due to permanent lubrication
and are designed for high mileages.
The brakes are accessible more easily.
With the ECO hub system (up to manufac
ture in 6/97) the entire bearing system with
hub can simply be pulled off the axle stub
with the integrated axle nut and re installed
again.
With axles manufactured after 6/97, first
dismantle the axle nut. The brake drum
with the compact bearing can then be
pulled off the axle stub.
Tightening torques:
SW 36 M = 280 Nm
SW 41 M = 330 Nm
(no bearing play adjustment)
If noticeable bearing play is felt, the
compact bearings should be replaced.

Taper roller bearings are recognisable by
the conical profile of the rollers.
Lever off hub cap. Remove split pin from
axle nut and tighten so that rotation of the
wheel is slightly braked.
Turn back the axle nut to the next possible
split pin hole, by a maximum of 30 degrees.
Insert split pin and bend ends slightly
outwards.
Check wheel rotation, fit hub cap.
Important:
The grease in the hub cap and bearing
must not be contaminated with dirt during
this work!
