Description

Overview

Heavy duty equaliser rocker pin assembly supports the equaliser or rocker in mechanical trailer suspension. It forms the main pivot through the equaliser bush, so it carries suspension movement and load transfer at the hanger. Because this point sees constant articulation, wear on the shaft or thread can create movement, noise and poor bush support. Replacing the pin assembly restores the correct bearing surface and helps the rocker move properly again.

Features

• Forged pin assembly with matching nut and washer
• 50mm shaft diameter for heavy suspension applications
• 295mm overall length
• 25.4mm thread size, commonly matched as 1″ UNF

Specifications and Materials

The forged construction follows the original design for this suspension style. The main selection points are 50mm shaft diameter, 295mm overall length and 25.4mm thread size, so match the pin against the old assembly before fitting. This pin runs through the equaliser bush and hanger assembly, and it supports the equaliser pivot in heavy mechanical trailer suspension. Part number: SP1201HD. For equaliser shaft installation and torque guidance on a matching mechanical suspension family, see the TMC 75 suspension service manual

Compliance and Safety

Inspect the equaliser bore, bush condition, washer faces and locknut seating during installation. If the old pin has worn a step into the shaft or damaged the bush sleeves, replace those parts at the same time so the new assembly does not run against worn mating parts. After fitting, tighten the assembly to the suspension maker specification and confirm that the rocker moves freely without bind.

Trailer Applications

Heavy duty equaliser rocker pin assembly supports the equaliser or rocker between the hanger plates in mechanical trailer suspension. Workshops commonly fit it during repairs for worn pins, loose rocker movement or bush replacement on freight and fleet trailers. It also suits jobs where the original pin, nut and washer need replacement as one complete assembly instead of separate hardware pieces.
