Description

Overview

The camshaft bush washer circlip kit Rockwell axle restores firm support for the S camshaft on heavy trailer axles. This kit replaces the inner bush, thrust washer and circlip in one job, so you keep camshaft movement under tight control. As a result, brake response stays more consistent across the axle, even under loaded conditions. The design focuses on Rockwell style trailer S cam drum brakes where precise cam location matters for even lining wear.

Features

• Complete inner camshaft hardware set for one axle, including matched bush, washer and circlip.
• Suits Rockwell style S cam drum brake axles that use a 4 bolt inner cam bracket.
• Controls radial and axial camshaft movement to help maintain balanced braking side to side.
• Lets workshops service common wear items together instead of sourcing individual components.

Specifications and Materials

Compliance and Safety

Only trained personnel should work on heavy vehicle brake systems, as incorrect assembly can affect stopping performance. Always secure the vehicle, chock wheels and isolate the air supply before starting work on the axle. After fitting the camshaft bush washer and circlip kit, check for free camshaft rotation, correct shoe travel and proper slack adjuster function. Next, carry out a controlled road test and confirm the trailer brakes apply smoothly without pull or imbalance.

Trailer Applications

Use this camshaft bush washer circlip kit Rockwell axle on semi trailers, B double combinations and other on highway trailers with compatible Rockwell style S cam brake axles. Fleet operators can standardise on this inner cam kit where multiple trailers share the same camshaft and bracket configuration.
