ATV Swingarm Bearings

SAFETY FIRST: Protective gloves and eyewear are recommended at this point.

Note: These instructions are very general, and you should have a service manual for your particular vehicle to get a better understanding of your particular setup and have factory recommended torque levels and specifications on hand.

Check out the Additional Service Information Resources for more information on finding service information for your specific vehicle.

This guide shows instructions for replacing the swingarm bearings for a shaft drive ATV. For some chain drive models the Motorcycle Swingarm Bearing Installation Guide may be more applicable.

Prep

Thoroughly clean the vehicle to make the job easier and prevent contamination of the new components during installation.

Get your swingarm bearing rebuild kit from ALL BALLS RACING.

Remove the contents of your ALL BALLS RACING swingarm rebuild kit. Layout the components in an organized manner for easy installation. Note: wait to do this until the old parts are removed and you are ready to begin installing the new components.

AB-trx350_0036

Remove the pivot lock nut with the special lock nut wrench.

Remove the bearing grease holder.

AB-trx350_0053

Clean away all of the old grease, grime, and rust from the bearing bores.

AB-trx350_0054

Inspect the bearing bores for wear and damage. Make sure the bores are free of damage or burrs that may cause the new bearings to hang during installation.

 

Bearing Replacement

AB-trx350_0055

Install the bearing grease holder.

AB-trx350_0056

Install the bearing race.

AB-trx350_0057

AB-trx350_0058

Lubricate the new bearing with grease.

AB-trx350_0059

Install the swingarm bearings into the races.

AB-trx350_0060

Apply grease to the lips of the dust seals.

AB-trx350_0061

Install the dust seals into the swingarm.

AB-trx350_0062

AB-trx350_0063

Use a driver that matches the outside diameter of the dust seal to push it into place if needed.

Installation

Take care to properly support the vehicles frame and swingarm so the vehicles weight is not applied to the swingarm until its fasteners are installed.

AB-trx350_0039

Apply a light coat of grease to the swingarm pivot bolts. Install the swingarm to the frame. Tighten the pivot bolts to specification.

AB-trx350_0036

Hold the pivot bolt and tighten the locknut to specification with the special locknut wrench.

AB-trx350_0038

Install the swingarm pivot caps.

AB-trx350_0040

Assemble the vehicle and tighten the fasteners to specification.

To make your bearings last longer- avoid pressure washing around the bearing seals for extended periods of time. Pressure washers will push water right around seals causing premature rusting of the bearings.
