FAQs
What type of grease should I use for lubrication?
The manufacturer recommends using molybdenum disulphide grease for lubricating the force screw and clamping arms.
Can this tool be used on non-ribbed pulleys?
This tool is specifically designed for ribbed auxiliary drive belt pulleys. Its clamping mechanism relies on the ribs for secure engagement.
What vehicles is this pulley puller most commonly used on?
It is commonly used on Ford, Citroen, Peugeot, and some Volvo vehicles, for components like water pumps, alternators, and A/C pulleys.
How do I ensure the force screw stays central?
The left and right-hand threaded clamping mechanism is designed to ensure the force screw remains central when the clamps engage equally onto the pulley.
What is included with the pulley puller?
The puller typically comes with 2 sets of quick-change clamps for different depth pulleys, 2 force screws, a centre-pointed end pin adaptor, and a flat end adaptor.
How often should I lubricate the tool?
It is recommended to lubricate the force screw and clamping arms well before each use to ensure optimal performance and longevity.
Troubleshooting
Clamps not gripping the pulley securely.
Ensure the toothed clamps are properly seated on the pulley ribs. Check if the correct size clamp arms are being used. Verify that the force screw is centered on the shaft.
Force screw is difficult to turn.
Confirm that the force screw and clamping arms are adequately lubricated with molybdenum disulphide grease. Check for any debris obstruction.
Puller is not applying even pressure.
Verify that both sides of the dual-threaded clamping mechanism are engaging the pulley simultaneously. Ensure the force screw remains central to the shaft.
Tool appears damaged or worn.
Inspect clamps, screws, and arms for signs of significant wear or damage. Contact the manufacturer or supplier for replacement parts if available.
Pros and Cons
Pros
- Secure and balanced force application prevents pulley damage.
- Includes multiple clamp sizes and force screws for versatility.
- Adaptable to various pulley depths and shaft types.
- Designed for common European vehicle applications.
- Ensures force screw remains central for stable operation.
Cons
- Requires specific lubrication (molybdenum disulphide grease) for optimal function.
- May not fit extremely large or unusually shaped pulleys.
- Can require some practice to position correctly on certain pulley designs.
- Relies on ribbed belt pulley design for effective clamping.
Setup, Compatibility & Care
Setup:
- Select the appropriate quick-change clamp arms (long or short) based on the pulley depth.
- Attach the clamp arms to the puller body.
- Position the puller onto the auxiliary drive belt pulley, ensuring the toothed clamps engage securely with the pulley's ribs.
- Select the correct force screw or end pin adaptor for the pulley shaft.
- Screw the force screw into the puller body until it contacts the shaft.
Lubrication: Before each use, ensure the force screw and clamping arms are well lubricated with molybdenum disulphide grease. This is critical for smooth operation and to prevent wear.
Compatibility: This tool is designed for ribbed auxiliary drive belt pulleys commonly found on Ford, Citroen, Peugeot, and some Volvo vehicles. It is compatible with pulleys on water pumps, alternators, air conditioning systems, and crankshafts.
Care:
- Clean the tool after each use to remove grease and debris.
- Store in a dry place to prevent rust.
- Regularly inspect clamps and screws for wear or damage. Replace parts if necessary.
- Re-apply lubricant as needed, especially before extended periods of storage.
