Hubs, hub bearings 5

General

Hub cap / ECOMETER
BPW trailer axles with the ECO Plus 2 unit have hub caps
(and ECOMETERS) with a bayonet fitting. H
The bayonet fitting replaces the previously usual threaded
connection.
A 120 mm installation spanner (BPW part number K
03.339.05.02.0, see also BPW tool catalogue) is needed
for fitting or removing the new hub caps with the bayonet
fitting. N
+ An impact driver must not be used for
fitting / removing hub caps or ECOMETERS
with a bayonet fitting!

Removal
To remove the hub cap it is turned anticlockwise through
approx. 30 degrees with the installation spanner (Fig.).
When turned further, the hub cap lifts clearly away from
the hub seat.
The released position is also indicated by markings on
the hub cap and on the wheel hub (Fig. / Arrows).
In the released position the hub cap can be removed from
the wheel hub by pulling it away.

Dismanting
Assembly
The seal between the hub cap and the wheel hub takes
the form of an O-ring in the case of the ECO Plus 2 unit.
The O-ring is inserted in the groove on the hub collar of Assembling
the wheel hub, and is to be replaced every time. The hub
cap itself is to be given a thin coating of BPW ECO-Li Plus
special long-life grease inside in the area of the bayonet
fitting, before assembly.
Corresponding markings in the hub cap and
on the hub make it easier to fit the hub cap.
The figure shows the hub cap in the correct position
for fitting, with the spanner engaged. After been
placed in position, the hub cap is pressed onto the hub
and at the same time turned in clockwise direction.
The hub cap is firmly in place when the position shown
in Fig. (arrows) has been reached.
