Use the factory Yamaha service manual for instructions on removing and/or installing any and all factory parts on your TW. Refer to all safety precautions and fastener torque specs for safe and proper installation.
Step 1: Lift rear tire off the ground and secure motorcycle to prevent falling.
Step 2: Remove rear axle nut (22mm). Loosen chain adjuster cams. Remove rear brake rod wing nut. Remove top chain cover (8mm). Slide axle forward and roll chain off of rear sprocket. Remove rear axle and wheel assembly from the motorcycle. Keep up with the axle spacers on both sides of the rear axle assembly. Slide out the brake shoe assembly from the brake drum. NOTE: This is when you will need to decide if you want to tackle the OEM bearing spacer from the OEM axle/hub or just order a new one. The Yamaha part number is 90560-17305-00. You will be required to remove the axle bearing on the brake drum side of the assembly and slide the spacer out. Removing this bearing is the hardest part of this job. A blind bearing puller works best for this application.
Step 3: Using a saw blade or grinding wheel, completely remove the lower chain guard bracket from the lower left inside of the swingarm. Use all safety precautions when doing this. Touch up with silver paint if desired. Next, remove the rear bolt (10mm) from the rear lower outer chain guide and place the 2 supplied washers under the bolt head, then reinstall.
Step 4: Carefully remove the sprocket side axle bearing seal from the OEM axle tube (small pry bar). This can be reused if desired in the new axle. Remove the rear drive sprocket (14mm). Remove the rear brake drum assembly from the OEM axle assembly (12mm). At this point you will need to install the supplied axle bearings and axle spacer. Make sure to use the proper installation method to prevent bearing damage and don't forget the bearing spacer. Two bearings in the sprocket side, one in the brake drum side. Reinstall sprocket side axle seal.
Step 5: Using the OEM hardware, secure the rear brake drum to the new axle/hub. Torque to factory spec.
Step 6: Slide new steel wheel/tire over the sprocket side of the axle/hub with the valve stem facing the sprocket side of the assembly. Secure with the supplied ⅜” carriage bolts and flange nuts. The nuts should be on the valve stem side of the wheel with the carriage bolt entering through the brake drum side of the wheel hub flange. Tighten to 20 ft-lbs.
Step 7: Reinstall rear sprocket onto the axle assembly using the OEM hardware and torque specs. Install left axle bearing seal into axle assembly. Reinstall brake shoe assembly into the right side of the axle. Reinstall both axle bearing spacers. Install new complete assembly into the motorcycle. Roll the chain onto the sprocket and adjust the chain as required. Tighten the axle nut to proper torque spec. Reinstall brake rod into brake arm and adjust wing nut as required.
Step 8: Make the necessary adjustments to trim/fit the OEM chain guard over the chain and install. Double check your work, lube the chain, and take it for a test drive!
