Changing the grease in the wheel
hub bearings
– every 1,000 hours in operation (latest
annually) –
Jack up and secure the vehicle, and
release the brakes.
Remove the wheels and bearing caps.
Remove the split pin and unscrew the
axle nut.
Using a suitable retractor, withdraw the
wheel hub with the brake drum, the roller
bearings and the sealing elements from
the axle stub.
Label or mark the wheel hubs and bearing
cages so that they do not become mixed
up during re�assembly.
Clean the brake, check for wear, make
sure that it is intact and operates correct�
ly, and replace any worn parts.
The inside of the brake must be kept free
of grease and dirt.
Clean the wheel hubs thoroughly on the
inside and the outside, removing every
trace of old grease.
Clean the bearings and seals thoroughly
(diesel oil) and check to ensure that they
are suitable for re�use.
Lightly grease the bearing seats before
fitting the bearings, and then assemble
all the parts in the reverse order.
Carefully drive the parts into place on the
bearing shells, without tilting or damaging
them.
Coat the bearings, the wheel hub cavity
between the bearings and the bearing cap
with grease before re�assembly.
The quantity of grease should fill approxi�
mately a quarter to a third of the space in
the assembled hub.
Fit the axle nut, and adjust the bearings
BPW trailer axles
and the brake.
Finally, check that everything is in
working order and carry out a suitable
test drive, correcting any faults that
you may discover.
The wheel hubs must only be lubricat�
ed with BPW special longlife grease
(ECO Li 91) with a drop point above
190 °C.
Using the wrong grease or excessive
quantities may lead to damage.
Damage can be caused by the mixing
of lithium�based grease with sodium�
based grease, because of incompati�
bility.
