Quick summary
- A punch made of hardened steel is best, but a sturdy screwdriver can be used in a pinch.
- Use the punch or drift to tap the inner race of the bearing.
- Use the punch to tap it into place, but be careful not to damage the race.
So, your motorcycle’s wheel bearing is making that dreaded grinding noise, and you’re ready to replace it. But you’re staring at the stubborn bearing, and the thought of buying a specialized puller is daunting. Don’t worry, you don’t *need* a puller to remove a motorcycle wheel bearing. This guide will walk you through a safe and effective method to remove that bearing without the need for specialized tools.
Gather Your Tools
Before you start, ensure you have the following:
- A good set of wrenches. You’ll need wrenches that fit the axle nuts and any other fasteners holding the wheel in place.
- A hammer. A rubber mallet is ideal, but a standard hammer will work if you’re careful.
- A punch or drift. A punch made of hardened steel is best, but a sturdy screwdriver can be used in a pinch.
- A block of wood. This will protect the bearing race and the surrounding components from damage.
- Penetrating oil. This will help loosen any stubborn fasteners.
- Safety glasses and gloves. Always protect your eyes and hands when working on your motorcycle.
Prepare the Wheel
1. Remove the wheel. Loosen the axle nuts and remove the wheel from the motorcycle.
2. Remove the brake caliper. This will give you better access to the bearing.
3. Inspect the bearing. Check for signs of wear, damage, or rust. If the bearing is damaged, it’s time for a replacement.
Removing the Bearing Race
1. Apply penetrating oil. Spray penetrating oil around the inner race of the bearing. Let it sit for a few minutes to loosen any rust or corrosion.
2. Position the block of wood. Place the block of wood against the inner race of the bearing. This will protect the bearing race from damage during the hammering process.
3. Tap the punch. Use the punch or drift to tap the inner race of the bearing. Start with light taps and gradually increase the force as needed. The goal is to drive the bearing race out of its housing.
4. Be patient. This process can take some time, especially if the bearing is rusted or stuck. Don’t force it – take your time and use consistent pressure.
Removing the Bearing
1. Remove the outer race. Once the inner race is removed, the outer race should come out easily. If it’s stuck, use the punch to tap it out from the opposite side.
2. Remove the bearing. The bearing itself should now be loose and easily removable. If it’s still stuck, use the punch to tap it out from the side.
Cleaning and Inspection
1. Clean the bearing housing. Once the bearing is out, clean the housing thoroughly. Remove any debris or rust to ensure a smooth fit for the new bearing.
2. Inspect the housing. Look for any signs of damage or wear. If the housing is damaged, it will need to be replaced.
3. Inspect the axle. Check for any signs of wear or damage. If the axle is damaged, it will need to be replaced.
Installing the New Bearing
1. Apply grease. Pack the new bearing with grease. This will help to lubricate the bearing and prevent rust.
2. Install the bearing. Carefully install the new bearing into the housing. Make sure it’s seated properly.
3. Install the outer race. Install the outer race into the housing. Use the punch to tap it into place, but be careful not to damage the race.
4. Install the inner race. Install the inner race into the housing. Use the punch to tap it into place, but be careful not to damage the race.
Reassembly
1. Install the axle. Install the axle through the bearing housing.
2. Install the wheel. Install the wheel back onto the motorcycle.
3. Install the brake caliper. Install the brake caliper back onto the motorcycle.
4. Tighten the axle nuts. Tighten the axle nuts to the proper torque specification.
Putting It All Together: Final Steps
1. Check for proper rotation. Spin the wheel to ensure it rotates smoothly and freely.
2. Check for any leaks. Check for any leaks from the bearing housing or axle seals.
3. Test ride. Take your motorcycle for a test ride to ensure the new bearing is working properly.
Wrapping Up: A Safe and Successful Repair
By following these steps, you can successfully remove and replace a motorcycle wheel bearing without using a specialized puller. Remember to use caution, work in a clean and well-lit area, and always wear safety glasses and gloves.
Frequently Discussed Topics
Q: What if the bearing is too stubborn to remove with a punch?
A: If the bearing is incredibly stuck, you can try using a bearing separator tool. This tool is designed to apply pressure evenly to the bearing, making it easier to remove. You can also try using a heat gun to gently warm the bearing, which can help to loosen it.
Q: How often should I replace my motorcycle wheel bearings?
A: There’s no set mileage or time interval for replacing wheel bearings. However, they should be inspected regularly for wear and tear. Signs of a failing bearing include grinding noises, rough wheel rotation, or a loose wheel.
Q: Can I use a regular hammer instead of a rubber mallet?
A: While a regular hammer can be used, it’s more likely to damage the bearing or surrounding components. A rubber mallet provides a softer impact, reducing the risk of damage.
Q: What if I can’t find the right size punch or drift?
A: You can use a sturdy screwdriver as a substitute, but be careful not to damage the bearing or housing. Ensure the screwdriver is the right size and that you’re applying pressure evenly.
Q: Can I reuse the old bearing races?
A: It’s not recommended to reuse old bearing races. They may be worn or damaged, even if they appear to be in good condition. Replacing the races with new ones ensures a smooth and long-lasting repair.
