Compact bearings
Compact bearings are maintenancefree
due to permanent lubrication and are
designed for high mileages.
Therefore, there is no grease change or
regreasing necessary.
Compact bearings are recognizable
by their cylindrical cap shape.
Axles, with compact bearing fitted, are
recognizable by a cylindrical hub cap.

Lubrication work
1 In the case of torsion bar axles:
lubricate the trailing arm bearing
– every 2,000 3,000 kilometres, or
annually –
Lubricate the grease nipples.
Grease quantity per grease point:
approx. 20 g.
2 Change wheel hub bearing grease
(does not apply to compact bearings)
– every year –
After every launch with boat trailers.
(Exception: Not necessary after every
launch if the axles have “Water Proof”
marked on their hub caps.)
Taper roller bearings and deep groove
ball bearing
Axles fitted with taper roller bearings
are recognizable by a tapered type
hub cap.
Remove wheels and wheel hubs.
Mark dismounted wheel hubs and
bearing races so that their identity is
not mistaken during reassembly.
Clean wheel hubs thoroughly inside and
outside. Remove old grease totally.
Clean taper roller bearings and seals
(using diesel oil) and check for re
useability.
Work BPW special longlife grease
ECOLi 91 into the cavities between the
taper roller and cage. Smear grease into
the hub's outer bearing race.
Fill the hub caps to 3/4 full with grease.
Fit wheel hubs, adjust the bearing play
and fit the hub caps. (Bearing adjustment
see page 14).
