Description

Overview

McGrath Hutch Fruehauf equaliser pin supports the centre rocker connection in mechanical trailer suspension that runs 75mm wide springs. It carries the rocker through its pivot point, so shaft size, length and thread must match the existing hardware before installation. When the pin wears, the bushes can loosen, the rocker can move off line, and the suspension starts to knock or wear unevenly.

Features

• Fits McGrath, Hutch and Fruehauf mechanical suspension setups with 75mm wide springs
• 19mm shaft diameter, 162mm overall length and 16mm thread
• Suits two pin bushes in the rocker assembly
• Used in centre rocker service and suspension rebuild work

Specifications and Materials

This equaliser pin suits mechanical spring suspension layouts that use two pin bushes at the rocker. Match the 19mm shaft diameter, 162mm overall length and 16mm thread before ordering. Check the old pin for wear marks, ovality and thread damage, because those signs often show bush movement inside the assembly. Part number: SP1204.

Heavy trailer design and maintenance guidance sits in the Department of Infrastructure vehicle standards bulletins for broader workshop reference.

Compliance and Safety

Install the pin with sound bushes, matching locking hardware and clean mounting faces, because worn adjoining parts can shorten service life straight away. Also inspect the rocker bore and side faces while the pin is out, then replace any parts that let the assembly move off centre. After fitting, torque the hardware correctly and recheck the suspension for free movement before the trailer goes back to work.

Trailer Applications

McGrath Hutch Fruehauf equaliser pin suits trailer suspension repairs where the centre rocker runs on a 75mm spring setup and uses two pin bushes. It is a practical replacement when the old pin shows scoring, thread damage or bush wear, because those faults can create noise, uneven movement and fast follow-on wear through the rocker assembly.
