Product Specifications

Designed for Galbreath Side Roller Assemblies

The Galbreath 38KP-300 cotter pin is used to retain side roller components on compatible Galbreath roll-off hoist systems.

Side rollers help guide the roll-off container during loading and unloading operations. Properly secured roller components are important for reliable equipment operation.

This cotter pin is used with the following Galbreath roller assemblies:

• Galbreath 381AO: 4-inch side roller assembly with pin.

• Galbreath 386AO: 3-inch side roller assembly with pin.

These assemblies also use the Galbreath E660 side roller washer, which works with the cotter pin and mounting hardware to retain the roller.

When replacing a side roller or roller pin, inspect the washer and cotter pin and replace worn or damaged retaining hardware as needed.

When Should You Replace a Side Roller Cotter Pin?

Cotter pins are generally intended as single-use retaining fasteners and should be replaced after removal.

Common reasons for replacement include:

• Bent, broken, or damaged retaining ends

• Excessive corrosion or deterioration

• Missing retaining hardware

• Loose or improperly secured roller pins

• Damage during roller disassembly

• Routine replacement during side roller maintenance

Never reuse a damaged or previously bent cotter pin when servicing a roll-off hoist roller assembly.

Why Proper Side Roller Retention Matters

The side roller assembly is an important part of the roll-off hoist's container guidance system.

The roller, mounting pin, washer, and cotter pin work together as a mechanical assembly.

Using the correct retaining hardware helps keep these components properly assembled during operation.

When replacing a cotter pin, verify the mounting hole dimensions, fastener length, and original manufacturer specifications.
