BPW specialist tools: what is needed for axle and hub service
BPW is one of the most common trailer axle manufacturers fitted to semi-trailers in UK operation. The ECO-Plus axle assembly uses a compact hub unit rather than conventional tapered roller bearings, which means the standard tool approach for hub and bearing service does not apply. Dedicated BPW tooling is required to extract and fit the ECO-Plus hub unit without damaging the axle stub.
The hub unit on the ECO-Plus axle is a sealed, pre-adjusted assembly. It threads onto the axle stub rather than being pressed on, so the correct adaptor is needed to torque it correctly during fitting. Under-torquing leads to premature hub failure; over-torquing risks thread damage. BPW publish specific torque values for each axle variant.
Frequently Asked Questions
Do I need specific tools to service a BPW ECO-Plus axle?
Yes. The ECO-Plus hub unit requires a dedicated adaptor to install and remove the threaded hub assembly correctly. Standard bearing removal tools will not provide the correct drive point and may damage the hub or axle.
Where can I find BPW ECO-Plus hub units and axle parts?
BPW axle parts including hub units, bearings, and brake components are available from Truckstop Group. Call us on 01527 598 000 with the axle serial number or trailer details and we can confirm the correct specification.
Are BPW tools compatible with SAF trailer axles?
BPW and SAF axle systems use different hub designs and the tooling is not cross-compatible. If you service both makes, you need separate tool sets for each. SAF axle parts and tools are also available from Truckstop Group.
How do I identify which BPW axle is fitted to a trailer?
The BPW axle type and serial number are stamped on the axle beam. BPW publish a cross-reference table on their website that maps serial numbers to axle specifications. The trailer manufacturer's build plate may also list the axle specification.
