Description

Overview

The repair camshaft bush outer spider supports the S cam at the spider end of Fuwa style trailer brake axles. This repair camshaft bush outer spider locates the camshaft in the outer bracket so the cam head runs true inside the brake shoes. As a result, you maintain more consistent brake response and reduce uneven lining wear on heavy trailer axles. Fleet workshops can use this bush during routine brake overhauls or targeted repairs when spider end support shows excess play.

Features

• Dedicated repair camshaft bush outer spider for Fuwa style drum brake trailer axles.
• 38mm internal diameter, 48mm outside diameter and 38mm length to match common Fuwa spider housings.
• Helps control camshaft radial and axial movement at the outer end of the S cam.
• Supplied as a single bush so you can replace only the worn spider location during service.

Specifications and Materials

This repair camshaft bush outer spider suits Fuwa pattern cam spiders used on heavy trailer axles with S cam drum brakes. The 38mm internal diameter matches the S cam journal size at the spider end, while the 48mm outer diameter and 38mm length match the correct housing bore on compatible Fuwa K-Hitch style axles. Part number: FB2244. For detailed technical guidance on heavy vehicle brake system setup and inspection, refer to the heavy vehicle brake standards bulletin issued by the NHVR.

Compatibility and Fitment

Use this repair camshaft bush outer spider on Fuwa K-Hitch and equivalent trailer axles where the outer spider bush supports the S cam near the brake shoes. Always clean the spider housing and measure the bore and cam journal to confirm the 38mm by 48mm sizing before pressing in the new bush. Replace bushes in axle sets where possible so cam support stays consistent side to side and brake balance remains even. This cross-reference listing means this part is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required.

Compliance and Safety

Only competent personnel should service heavy vehicle brake systems, because incorrect camshaft support can affect braking performance. Always secure the trailer, apply park brakes, chock wheels and isolate the air supply before removing any brake components. After installing the repair camshaft bush outer spider, check camshaft rotation by hand, verify end float, and confirm correct slack adjuster operation. Then carry out a controlled road test and monitor drum temperature and brake response to ensure the axle performs as expected.

Trailer Applications

Typical applications for this repair camshaft bush outer spider include semi trailers, B double combinations and other highway or regional haul trailers running Fuwa K-Hitch drum brake axles. Fleet operators can standardise on this bush where multiple trailers share the same spider and camshaft configuration. In addition, workshops can keep several bushes on hand so they can complete urgent roadside repairs or workshop overhauls without delay.
