Posi Lock TJ-2 Transmission Bearing Puller User Manual

1. Product Overview

The Posi Lock TJ-2 is a specialized three-jaw manual transmission bearing puller designed for the extraction of various shaft-fitted components. This includes bearings, wheels, bushings, gears, and pulleys, particularly those found in manual transmissions of rear-wheel-drive foreign and domestic cars, trucks, and vans.

Its unique design allows the jaws to clamp securely into snap ring grooves as narrow as 0.070 inches, facilitating the removal of front input shaft bearings on 3-speed, 4-speed, 5-speed, 3-speed overdrive, and 4-speed overdrive manual transmissions.

Key Features:

• Three-Jaw Construction: Ensures equal load distribution, a secure hold, and concentric pulling action, minimizing damage to components.
• Forged Steel Jaws: Provides increased strength and durability compared to investment casting.
• Optimal Reach and Spread: Features a 5.25-inch (133 mm) reach and a spread range of 1 to 6.75 inches (25 to 171 mm) for versatile application and increased pulling leverage.
• Tapered Jaws: Specifically designed to fit into narrow snap ring grooves, down to 0.07 inches, for specialized bearing removal.

2. Safety Information

Always prioritize safety when operating any mechanical tool. Failure to follow safety guidelines can result in injury or damage to the tool or workpiece.

• Wear Eye Protection: Always wear ANSI-approved safety glasses or goggles to protect against flying debris.
• Wear Hand Protection: Use appropriate gloves to protect hands from pinch points and sharp edges.
• Inspect Tool Before Use: Before each use, inspect the puller for any signs of damage, wear, or deformation. Do not use a damaged tool.
• Secure Workpiece: Ensure the component being pulled and the surrounding assembly are stable and securely supported.
• Apply Even Pressure: When tightening the puller, apply even pressure to prevent the jaws from slipping or damaging the component.
• Do Not Over-Tighten: Avoid excessive force, which can damage the puller or the component. If the component does not move, reassess the setup.
• Keep Clear: Keep hands and other body parts clear of the pulling path and potential pinch points.
• Use Correct Size: Ensure the puller's reach and spread are appropriate for the component being removed.

3. Components and Parts

The Posi Lock TJ-2 Transmission Bearing Puller consists of the following primary components:

• Puller Body/Frame: The main structure that houses the forcing screw and jaw assembly.
• Forcing Screw: The central threaded rod that applies pressure to extract the component.
• Three Jaws: The gripping arms that attach to the component. These are replaceable and interchangeable.
• Jaw Tips: The tapered ends of the jaws designed to fit into narrow grooves.
• Locking Collar/Mechanism: Secures the jaws in place around the component.

4. Setup

1. Assess the Component: Identify the bearing or component to be removed. Determine its size, location, and the presence of any snap ring grooves.
2. Select Jaws: Ensure the puller's jaws are appropriate for the task. The TJ-2's tapered jaws are specifically designed for narrow snap ring grooves.
3. Position the Puller: Place the puller over the component. Extend the jaws to engage the component securely. For bearings with snap ring grooves, carefully insert the tapered jaw tips into these grooves.
4. Secure the Jaws: Tighten the locking collar or mechanism to firmly hold the jaws in position around the component. Ensure all three jaws are equally engaged and applying even pressure.
5. Center the Forcing Screw: Position the tip of the forcing screw directly against the center of the shaft or the component from which the bearing is being pulled.

5. Operating Instructions

1. Initial Engagement: Once the puller is securely set up, begin to turn the forcing screw clockwise using an appropriate wrench. Turn slowly and observe the engagement of the jaws.
2. Apply Gradual Pressure: Continue to turn the forcing screw, applying gradual and steady pressure. The component should begin to move off the shaft. Avoid sudden or jerky movements.
3. Monitor Progress: Watch the component as it is being pulled. Ensure it is moving evenly and that the jaws maintain their grip. If the jaws show any sign of slipping, stop immediately and re-secure them.
4. Complete Removal: Continue turning the forcing screw until the component is fully separated from the shaft.
5. Release and Remove: Once the component is free, loosen the forcing screw and the jaw locking mechanism. Carefully remove the puller and the extracted component.

Important Note: If the component is particularly stubborn, do not apply excessive force. Re-check the setup, ensure proper lubrication if applicable, and consider applying penetrating oil to the component-shaft interface. Some components may require a slight tap with a hammer on the forcing screw (while under tension) to break free, but this should be done with caution and only if necessary.

6. Maintenance

Proper maintenance ensures the longevity and reliable performance of your Posi Lock TJ-2 puller.

• Cleaning: After each use, wipe down the puller to remove any grease, dirt, or debris.
• Lubrication: Periodically apply a light coat of machine oil or grease to the forcing screw threads to ensure smooth operation and prevent corrosion.
• Inspection: Regularly inspect the jaws, forcing screw, and puller body for signs of wear, cracks, bends, or other damage. Pay close attention to the jaw tips.
• Storage: Store the puller in a clean, dry environment to prevent rust and damage.
• Jaw Replacement: If jaws become damaged or worn, replace them with genuine Posi Lock replacement parts to maintain optimal performance and safety.

7. Troubleshooting

• Problem: Jaws are slipping off the component.
  • Solution: Ensure the jaws are fully engaged and the locking mechanism is tightened securely. Verify the jaw tips are properly seated in any available grooves. The three-jaw design is intended to prevent slipping, so re-evaluation of engagement is crucial.
• Problem: Component is not moving despite significant force.
  • Solution: Stop applying force. Re-inspect the setup to ensure the puller is correctly aligned and the forcing screw is centered. Apply penetrating oil to the component-shaft interface and allow time for it to work. Ensure the component is not seized by rust or other obstructions.
• Problem: Puller appears damaged or bent.
  • Solution: Discontinue use immediately. Do not attempt to repair damaged components of the puller. Contact Posi Lock customer support for guidance on replacement parts or service. Using a damaged tool can lead to serious injury.
