Designed for Dragon Roll-Off Trailer Side Rollers
The Dragon 805-0090 cotter pin is listed in Dragon's replacement parts catalog alongside the side roller retaining components.
Side rollers help guide roll-off containers during loading and unloading operations. The roller assembly includes mechanical components that must remain properly retained during equipment operation.
The cotter pin passes through an appropriately sized retaining hole, and its split ends are bent after installation to help prevent the retaining hardware from backing out.
When servicing a Dragon side roller assembly, inspect the cotter pin, retaining washer, roller shaft, and other mounting components for wear or damage.

When Should You Replace a Side Roller Cotter Pin?
Cotter pins are generally intended for single use and should be replaced after removal during equipment maintenance.
Common reasons for replacement include:
-
Bent, broken, or damaged retaining ends
-
Missing cotter pins
-
Excessive corrosion or deterioration
-
Loose or improperly secured retaining hardware
-
Damage during roller disassembly
-
Replacement of side rollers, mounting shafts, or retaining washers
Important: Do not reuse a cotter pin that has already been bent during installation. Replace it with a new fastener of the correct size and specification.
Why Proper Side Roller Retention Matters
A properly assembled side roller helps guide the roll-off container during loading and unloading.
The cotter pin works with compatible mounting hardware to help retain components in their intended positions.
Using the correct cotter pin diameter and length is important for proper installation.
Before replacing a cotter pin, verify the retaining hole size, overall pin length, and equipment manufacturer's installation requirements.
