Description

Overview

The equaliser rocker bush and pin kit services the main pivot in matching mechanical trailer suspension rocker assemblies. It combines the tapered bush with the heavy-duty pin hardware used through the equaliser, so the bush bore, pin diameter and overall pin length are the main checks before ordering.

Features

• Includes a tapered equaliser bush and heavy-duty rocker pin assembly.
• Pin assembly includes the matching nut and washer.
• Heavy-duty pin uses a 50mm shaft and measures 295mm overall.
• Bush measures 51.4mm inside diameter and 112.3mm long.

Specifications and Materials

The bush supports movement around the equaliser pivot while the forged pin assembly passes through the bush and hanger. Match the old bush profile and pin dimensions before installation.

Part number: 090.525.

Compatibility and Fitment

Check the removed rocker bush and pin before ordering. The important points are the tapered bush profile, 51.4mm bush bore, 50mm pin shaft, 295mm pin length and the suspension hanger arrangement. Similar mechanical suspension parts can look alike while using different pin or bush dimensions.

Related Parts

The bush and pin assembly can also be serviced individually where only one component of the pivot needs replacement.

Compliance and Safety

Inspect the equaliser bore, hanger faces and surrounding suspension hardware while the pivot is dismantled. Replace damaged mating parts before fitting the new bush and pin, then tighten the pin hardware to the suspension manufacturer procedure and confirm the rocker moves without binding.

Trailer Applications

The equaliser rocker bush and pin kit suits matching mechanical trailer suspension rockers using a tapered equaliser bush and 50mm heavy-duty pivot pin arrangement.

Why Choose ICS Trailers

Rocker pivots can wear through the bush, pin or both, so checking both pieces while the suspension is apart can prevent a new component from running against a worn mating surface. ICS Trailers can compare the old bush profile, pin dimensions and suspension photos when the original numbers are difficult to read.

• Measure the bush bore and pin shaft before ordering when the old parts are unmarked.
• Check the rocker bore and hanger condition during the same repair.
