Ultimate Guide to Harley Davidson Wheel Bearing Puller

Introduction

Harley Davidson wheel bearing pullers are essential tools for maintaining and repairing Harley Davidson motorcycles. These specialized tools are designed to safely and effectively remove and install wheel bearings, a critical component of the motorcycle's suspension system.

Types of Harley Davidson Wheel Bearing Pullers

There are two main types of Harley Davidson wheel bearing pullers:

1. Manual Wheel Bearing Pullers:

• Utilizes a threaded rod and a slide hammer to extract bearings.
• Ideal for occasional use or DIY projects.

2. Hydraulic Wheel Bearing Pullers:

• Uses hydraulic pressure to generate high force, making them suitable for heavy-duty applications.
• More expensive but offers greater efficiency and ease of use.

How to Choose the Right Wheel Bearing Puller for Your Harley Davidson

When selecting a wheel bearing puller for your Harley Davidson, consider the following factors:

• Type of Motorcycle: Different Harley Davidson models may require specific pullers.
• Bearing Size: Choose a puller that is compatible with the size and type of bearings on your motorcycle.
• Frequency of Use: If you frequently work on your motorcycle, a more durable and powerful puller is recommended.
• Budget: Manual pullers are generally more affordable than hydraulic models.

Step-by-Step Approach to Using a Harley Davidson Wheel Bearing Puller

Safety Precautions:

• Wear appropriate safety gear (gloves, eye protection).
• Ensure the motorcycle is stable and on a level surface.

Materials:

• Wheel bearing puller
• Screwdriver
• Hammer (for manual pullers)
• Hydraulic pump (for hydraulic pullers)

Instructions:

1. Prepare the Bearing:

• Remove the wheel from the motorcycle.
• Loosen the axle nut and slide it off.
• Use a screwdriver to pry out the dust cover.

2. Attach the Puller:

• Screw the threaded rod (manual puller) or hydraulic cylinder (hydraulic puller) onto the bearing.
• Position the slide hammer (manual puller) or hydraulic pump (hydraulic puller) onto the threaded rod/cylinder.

3. Remove the Bearing:

• Strike the slide hammer (manual puller) with the hammer or activate the hydraulic pump (hydraulic puller).
• The bearing will be pulled out of the hub.

4. Install the New Bearing:

• Apply a thin layer of bearing grease to the new bearing.
• Press the new bearing into the hub using the puller in reverse.
• Reinstall the axle nut and dust cover.

Common Mistakes to Avoid

• Using Excessive Force: Overtightening or striking the puller with excessive force can damage the bearing or puller.
• Ignoring Safety Precautions: Always wear proper safety gear and ensure the area is safe before working.
• Not Cleaning the Bearing Surface: Failure to remove dirt or debris from the bearing surface can interfere with proper installation.
• Reusing Old Bearings: Worn or damaged bearings should be replaced to ensure optimal performance.

Frequently Asked Questions (FAQs)

1. How often should I replace my wheel bearings?

Typically every 30,000-40,000 miles, depending on riding conditions and frequency.

2. What are the signs of worn wheel bearings?

• Grinding or humming noises while riding
• Excessive play in the wheel
• Vibration in the handlebar or footpegs

3. Can I replace wheel bearings myself?

Yes, with the right tools and knowledge, but it is recommended to seek professional assistance if you are not comfortable working on your motorcycle.

4. What is the torque specification for the axle nut?

Refer to your Harley Davidson service manual for specific torque values.

5. How much does a Harley Davidson wheel bearing puller cost?

Manual pullers range from $20-$50, while hydraulic pullers can cost anywhere from $100-$500.

6. Where can I find a Harley Davidson wheel bearing puller?

Authorized Harley Davidson dealerships, motorcycle parts retailers, and online retailers.
