The Harley-Davidson Wheel Bearing Puller: A Comprehensive Guide

Understanding the Harley-Davidson Wheel Bearing Puller

The Harley-Davidson wheel bearing puller is a specialized tool designed to extract wheel bearings from the Harley-Davidson motorcycle wheel hubs. Wheel bearings are crucial components that support the motorcycle's weight and allow smooth wheel rotation. Over time, these bearings can become damaged, worn, or corroded, necessitating their replacement.

How Wheel Bearings Work

Wheel bearings consist of inner and outer races and spherical roller elements. The inner race fits onto the motorcycle's axle, while the outer race fits into the wheel hub. The roller elements rotate between the races, reducing friction and providing smooth wheel rotation.

Signs of a Failing Wheel Bearing

• Loud grinding or humming noises coming from the wheel
• Increased play or looseness in the wheel
• Uneven tire wear
• Reduced braking performance

Selecting the Right Puller for Your Harley-Davidson

Harley-Davidson offers a wide range of wheel bearing pullers designed for different motorcycle models. Choosing the correct puller is essential to ensure a successful and safe bearing removal.

Types of Pullers

• Standard Pullers: For general-purpose bearing removal on most Harley-Davidson models.
• Specialty Pullers: Designed for specific motorcycle models or types of bearings.
• Hydraulic Pullers: Provide additional force for removing stubborn bearings.

Choosing the Right Puller

Consider the following factors when selecting a puller:

• Motorcycle model: Ensure the puller is compatible with your specific Harley-Davidson motorcycle.
• Bearing size and type: Determine the size and type of bearing you need to remove.
• Puller capacity: The puller's capacity should exceed the removal force required for the bearing.
• Ease of use: Choose a puller that is easy to handle and operate.

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

Tools and Materials Required

• Harley-Davidson wheel bearing puller
• 3/4-inch socket wrench
• 3/4-inch socket
• penetrating oil
• soft-faced hammer

Safety Precautions

• Wear safety glasses and gloves.
• Place the motorcycle on a stable surface and secure it with a stand.
• Allow the motorcycle to cool down before attempting any work.

Step 1: Remove the Wheel

• Loosen the wheel axle nut.
• Lift the motorcycle off the ground using a jack and support stand.
• Remove the wheel axle nut and washer.
• Carefully remove the wheel from the motorcycle.

Step 2: Position the Puller

• Locate the wheel bearing on the wheel hub.
• Place the puller's jaws around the outer race of the bearing.
• Ensure the puller is properly seated on the bearing.

Step 3: Apply Penetrating Oil

• Apply penetrating oil around the outer race of the bearing.
• Allow the oil to penetrate the bearing for several minutes.

Step 4: Tighten the Puller

• Use the socket wrench to tighten the puller's bolt.
• Gradually increase the force until the bearing loosens.

Step 5: Tap the Bearing

• If the bearing is stuck, gently tap the puller's bolt with a soft-faced hammer.
• This helps loosen stubborn bearings.

Step 6: Remove the Bearing

• Continue tightening the puller's bolt until the bearing is completely removed.
• Carefully remove the puller from the bearing.

Tips and Tricks

• Heat the bearing slightly before pulling it. This helps expand the bearing and loosen it from the hub.
• Use a hydraulic puller for particularly stubborn bearings.
• Apply anti-seize compound to the new bearing before installation. This prevents future corrosion and makes future bearing removals easier.

Common Mistakes to Avoid

• Using the wrong puller for your motorcycle.
• Applying excessive force when tightening the puller.
• Pulling the bearing off-center.
• Damaging the wheel hub or bearing during removal.

Funny Stories and What We Learn

1. The Slow-Motion Pull: A novice mechanic attempted to remove a wheel bearing but applied so little force that it took over an hour to pull the bearing off. The lesson: Patience is not always a virtue when using a bearing puller!
2. The Flying Bolt: A mechanic forgot to tighten the puller's bolt securely. As he tightened the bolt, it shot off like a rocket, narrowly missing his head. The lesson: Always double-check your connections!
3. The Crushed Hub: A mechanic applied excessive force when tightening the puller, crushing the wheel hub in the process. The lesson: Respect the limitations of your tools and the components you're working on.

Call to Action
