Description
Overview
The Fuwa K-Hitch greaseless fifth wheel top is a fabricated steel Fleet Master coupling designed for heavy-duty B-double and road train applications. It features a 50mm adjustable single-piece jaw and supplied greaseless wear inserts, providing a low-friction contact surface for the trailer skid plate.
With a 195kN D-rating, this standard-width model suits demanding on-road and off-road transport operations. The top-only configuration allows replacement of the fifth wheel coupling without purchasing a complete mounting assembly.
Features
- Adjustable single-piece jaw accommodates normal king pin wear.
- Greaseless wear inserts reduce lubrication requirements across the top plate.
- Fabricated steel construction with a standard 915mm top width.
- Short operating handle and serviceable locking components.

Compatibility and Fitment
When replacing a greaseless fifth wheel top, confirm the existing coupling series, 50mm king pin size and mounting arrangement. In particular, check the pivot feet, bushes and mounting height because the top-only assembly must match the existing support configuration.
The Fleet Master range includes standard and extra-wide variants, so compare the existing top width before ordering.

Compliance and Safety
Follow the manufacturer’s mounting and jaw adjustment procedures before returning the coupling to service. Check the locking wedge, pivot security and jaw engagement, particularly after replacing the top assembly.
During coupling, avoid using the greaseless fifth wheel to lift the trailer because this can damage the wear inserts. Keep the locking mechanism correctly lubricated and inspect the pads for damage.
Trailer Applications
Fleet Master fifth wheels suit heavy transport combinations including road trains, B-doubles, stock crates, tankers and tippers. The fabricated construction and adjustable jaw support applications involving frequent coupling, varied road conditions and heavy trailer loads.
