Description

Overview

Ringfeder 50mm Coupling Repair Kit restores key wear components inside Ringfeder automatic trailer couplings, so the coupling closes and locks with the correct feel. It suits workshop major services on 50mm couplings where guide bushes, wear pads and locking hardware have started to loosen or bind. Because these parts work together, replacing them as a set helps you avoid chasing recurring play or uneven wear.

Features

Compliance and Safety

A coupling repair affects a primary safety connection, so only service it if you have the correct tooling and procedures for heavy trailer coupling hardware. Also check the coupling body for cracking, elongated holes, or damaged retainers before you fit new parts, because fresh bushes will not fix a worn housing. After assembly, verify positive locking and safe release function, then re-check after the first period of use.

Trailer Applications

Ringfeder 50mm Coupling Repair Kit suits dog trailers and drawbar combinations that use Ringfeder 50mm automatic couplings in Australian road service. It also suits fleets that schedule preventative maintenance, because the kit supports repeatable servicing across common coupling models. If you are unsure which coupling you have, confirm the coupling type plate or casting marks first, then match the service items to the correct maintenance routine.
