Description

Overview

The BPW ECO Plus hub cap closes the threaded outer end of a grease-filled ECO Plus wheel hub and protects the wheel-end bearing area during service. This version uses an M136 x 2.5 internal thread, 140mm outside diameter and 70mm depth, making thread size and hub generation the main ordering checks.

Features

• M136 x 2.5 internal thread for matching ECO Plus hubs
• 140mm outside diameter and 70mm overall depth
• 110mm across-flats hex for the correct service tool
• Steel screw-on construction for grease-filled wheel ends

Compatibility and Fitment

Match the removed cap’s M136 x 2.5 thread, 140mm OD and 70mm depth before fitting. BPW changed earlier M135 x 2 hub-cap threads to M136 x 2.5, so check the thread marking on the old cap rather than relying on appearance alone.

Related Parts

Check these wheel-end parts when the hub is open for service.

Compliance and Safety

Clean and inspect the hub thread before installation, then start the cap square to avoid cross-threading. BPW specifies 800 Nm for this steel ECO Plus hub cap. Use the correct 110mm A/F tool and replace the cap if the thread, seating surface or hex is damaged.

Trailer Applications

Workshops fit the BPW ECO Plus hub cap during wheel-end service on compatible grease-filled trailer hubs, particularly when the original cap has damaged threads, impact damage or no longer seats correctly.

Why Choose ICS Trailers

ECO Plus hub caps from different generations can look very similar, while thread size and depth determine whether the cap will seat correctly. ICS Trailers can help compare the old cap marking, M136 x 2.5 thread, 140mm diameter and wheel-end details before you order.

• Match surrounding ECO Plus wheel-end parts during hub servicing.
• Cross-check old part numbers and cap dimensions when identification is unclear.
