General

ECO Plus 2
Hub cap / ECOMETER
BPW trailer axles with the ECO Plus 2 Unit have hub caps
(and ECOMETERS) with a bayonet ﬁ tting.
The bayonet ﬁ tting replaces the previously usual threaded
connection.
A 120 mm installation spanner (BPW part number
03.339.05.02.0, see also BPW tool catalogue) is needed
for ﬁ tting or removing the new hub caps with the bayonet
ﬁ tting.

 An impact driver must not be used for

ﬁtting / removing hub caps or ECOMETERS
with a bayonet ﬁ tting!

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.

Dismantling

Assembly
The seal between the hub cap and the wheel hub takes Assembling
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
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
ﬁ tting, before assembly.
Corresponding markings in the hub cap and on the hub
make it easier to ﬁ t the hub cap.
The ﬁ gure shows the hub cap in the correct position for
ﬁ tting, 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 ﬁ rmly in place when the position shown
in Fig. (arrows) has been reached.
