Hack the Motorcycle Wheel Bearing: How to Remove It Without a Puller

Motorcycle wheel bearings play a crucial role in ensuring smooth and safe riding. However, removing them without a dedicated puller can be a daunting task. This comprehensive guide will provide you with step-by-step instructions and alternative techniques to remove motorcycle wheel bearings without a puller.

Preparation

Before attempting to remove the wheel bearings, gather the necessary tools:

• Socket wrench or impact wrench
• Socket set
• Screwdriver
• Hammer
• Drift or punch
• Penetrating oil (optional)

Step-by-Step Instructions

1. Remove the Wheel

• Loosen the axle nut using the socket wrench or impact wrench.
• Carefully remove the axle and pull out the wheel.

2. Remove the Brake Caliper

• Unbolt the brake caliper mounting bolts and remove the caliper.
• Hang the caliper out of the way using a bungee cord or wire.

3. Remove the Dust Seal

• Use a screwdriver to pry out the dust seal from the bearing housing.

4. Apply Penetrating Oil (Optional)

• If the bearing is stuck, apply penetrating oil around the bearing to loosen it. Allow it to sit for a few minutes.

5. Use a Drift or Punch

• Insert a drift or punch into the gap between the bearing and the wheel hub.
• Tap the drift or punch lightly with a hammer to drive the bearing out.
• Rotate the bearing as you tap to prevent damage to the hub.

6. Use a Socket Extension

• If a drift or punch is not available, insert a socket extension into the bearing housing.
• Use the socket wrench or impact wrench to gently tap the socket extension against the bearing.

7. Use a Slide Hammer (Optional)

• For stubborn bearings, a slide hammer can be used.
• Attach the slide hammer to the bearing using a suitable adapter.
• Pull the slide hammer back and release it to generate force to remove the bearing.

Alternative Techniques

1. Heat Expansion

• Heat the bearing housing around the bearing using a heat gun or torch (avoid overheating).
• As the housing expands, the bearing should loosen and become easier to remove.

2. Vise Grip Method

• Clamp a vise grip onto the bearing, ensuring the jaws grip the inner race.
• Rotate the vise grip while pulling it outwards to remove the bearing.

3. Chisel and Hammer Method

• Insert a chisel into the gap between the bearing and the hub.
• Tap the chisel lightly with a hammer to break the bond between the bearing and the hub.
• Use a drift or punch to drive the bearing out.

Reinstallation

• Clean and inspect the bearing housing and the new bearing.
• Apply a small amount of grease to the bearing.
• Carefully insert the new bearing into the housing.
• Use a socket extension or drift to gently tap the bearing into place.
• Install the dust seal and brake caliper.
• Tighten the axle nut to the specified torque.
