3. Setup and Preparation

Before using the Schley 99700 tool, ensure the engine is cool and all necessary safety precautions are observed. This includes wearing appropriate personal protective equipment (PPE) such as safety glasses and gloves.

1. Identify the Valve Lifter: Locate the hydraulic valve lifters that require removal or installation.
2. Access the Area: Ensure clear access to the cam tower, cam lobe, and valve spring retainer. This may involve removing other engine components as per the vehicle's service manual.
3. Clean the Area: Clean any debris or oil from around the valve lifter and spring assembly to prevent contamination.

4. Operating Instructions

Follow these steps carefully for the proper use of the valve lifter removal tool:

1. Position the Tool: Carefully slide the working end of the Schley 99700 tool between the cam tower and the cam lobe. Ensure it is positioned correctly over the valve spring retainer.
2. Depress the Valve Spring: Apply upward pressure on the tool's handle. This action will depress the valve spring, compressing it and creating clearance.
3. Remove the Lifter: Once the valve spring is sufficiently depressed, the hydraulic valve lifter can be carefully removed from its bore. Use appropriate lifter removal pliers or magnets if needed.
4. Install the Lifter (if applicable): For installation, reverse the process. Place the new or serviced lifter into its bore, then use the tool to depress the valve spring, allowing the lifter to seat properly.
5. Release Pressure: Slowly and carefully release the upward pressure on the tool, allowing the valve spring to extend and seat the lifter.
6. Verify Seating: Ensure the valve lifter is correctly seated and the valve spring is properly positioned.

Caution: Always refer to the vehicle manufacturer's service manual for specific procedures and torque specifications when working on engine components.

5. Maintenance and Storage

Proper maintenance and storage will extend the life of your Schley 99700 tool.

• Cleaning: After each use, wipe the tool clean of any oil, grease, or debris using a clean cloth.
• Lubrication: A light coat of rust-preventative oil can be applied to the metal parts if the tool will be stored for an extended period or in a humid environment.
• Storage: Store the tool in a dry, clean place, away from excessive moisture and corrosive chemicals. Keep it in its original packaging or a dedicated toolbox to prevent damage.
• Inspection: Periodically inspect the tool for any signs of wear, bending, or damage. Do not use a damaged tool.

7. Troubleshooting

If you encounter issues while using the Schley 99700 tool, consider the following:

• Tool Not Fitting: Ensure the tool is correctly aligned with the cam tower, cam lobe, and valve spring retainer. Verify that the engine type is listed in the "Applications" section.
• Difficulty Depressing Spring: Check for any obstructions. Ensure the tool is clean and free of debris. If the spring is unusually stiff, verify it is the correct spring for the application. Do not force the tool.
• Lifter Not Releasing/Seating: Ensure the valve spring is fully depressed. Check for any binding or damage to the lifter or its bore.
