  • Page 6 When only replacing the Bearings and reusing the old Hub, then the Bearing Race should be replaced at the same time. Bearing Kit (416-860-470) Remove the old Bearing Race in the Wheel Hub from both ends. This can be done by knocking the Bearing Race out from the opposite end it is positioned.
  • Page 7 Repeat for the Bearing Race in the opposite end of the Hub. If you have a bearing greasing tool, then use this to fully grease the Bearings before assembling the Hub. If you do not have a bearing greasing tool you can still grease the bearings by hand.
  • Page 8 Grease the Bearing Race in the Hub. Place the LARGE Tapered Roller Bearing (401-842-830) in the race. Apply another coat of grease to the LARGE Tapered Roller Bearing Position the Seal Insert (416-860-480) Gently tap the Seal Insert into place. See inset.

  • Page 10 Fit the Washer (308-200-064) over the Axle thread. Fit the Castle Nut (416-842-200) onto the Axle thread. Torque the Castle Nut to 68Nm WHILE ROTATING THE HUB. IMPORTANT: Do not use an impact gun for this step or bearing/hub damage may occur. Back the Castle Nut off one full turn.
  • Page 11 Insert the Split Pin (201-447-000) through the Castle Nut and the hole in the end of the Axle Stub. Bend the Legs of the Split Pin around the Nut. Note: The Short Leg of the Split pin may require trimming with Snips to clear the Washer and Bearing.

  • Page 13 Secure in place with a Shaft Locking Pin. Fit the Wheel to the wheel hub. Nip up the Wheel Nuts to secure using the pattern shown. The Tapered ends of the Wheel Nuts face the Wheels. Note: The Wheel Nuts will be torqued once the Chassis is lowered to the ground.
