Description

Overview

This camshaft washer and circlip kit Fruehauf suits heavy trailer S-cam brakes on 1 5/8″ camshafts. It helps keep the brake cam correctly located in the hardware stack. In addition, it supports consistent cam end float so the S-cam runs smoothly and delivers predictable brake response.

Features

This kit combines a camshaft thrust washer and matching circlip so you can replace worn hardware in one go. The parts suit typical Fruehauf style 1 5/8″ S-cam shafts common on many trailer axles, which simplifies workshop stocking. The simple design also makes inspection and replacement quicker during routine brake service.

Specifications and Materials

Part number: FB3109.
This camshaft washer and circlip kit Fruehauf typically fits 1 5/8″ S-cam brake shafts on heavy trailers. A thrust washer and circlip retain the cam at the spider end. Manufacturers use durable steel for the components to handle repeated brake applications and high clamp loads.

Compliance and Safety

Correct camshaft retention supports reliable foundation brake performance, so inspect the washer seat and the camshaft groove before fitting the circlip. Also confirm cam end float against the axle or brake manufacturer recommendations. Replace any other worn S-cam hardware at the same time so the brake system is more likely to hold adjustment and deliver stable braking.

Trailer Applications

Workshops typically use this camshaft washer and circlip kit Fruehauf during brake relines and drum changes. It also suits general S-cam overhaul work on heavy trailers, including fleets running Fruehauf style axles with standard 1 5/8″ camshafts. Because these camshafts can be used across multiple axle positions, the compact kit is easy to keep on hand in the workshop. Technicians can replace damaged retainers instead of reusing worn parts, which supports more consistent service results.
