Product Information
Full details
The AB Tools AT440 Pulley Remover is an essential diagnostic and maintenance tool designed for professional mechanics and automotive DIY enthusiasts who need to safely extract stubborn, seized, or difficult-to-reach pulleys from alternators, water pumps, and air conditioning units. Its standout benefit is the low-profile design that ensures access in cramped engine bays without damaging delicate pulley components. While highly versatile and durable, users should note that it is intended specifically for ribbed drive pulleys and may not be compatible with non-standard or specialty harmonic balancers.

FAQs
Does this tool work on harmonic balancers?
No, this tool is specifically designed for ribbed auxiliary and crankshaft drive pulleys. It is not designed to pull large, high-torque harmonic balancers.
What is the drive size for the tool?
The tool features a 3/8-inch drive, suitable for standard workshop ratchets.
Can this be used on serpentine belts?
Yes, it is designed for pulleys associated with ribbed serpentine belt systems.
Is the Allen key included?
Yes, a hex Allen key is included in the package for necessary adjustments.
Will the phosphate finish rust?
The black phosphate finish is highly resistant to corrosion, but as with all steel tools, it should be kept dry and wiped clean after use to ensure longevity.
Troubleshooting
The puller arms keep slipping off the pulley.
Ensure the knurled screws are fully tightened and the arms are seated deeply behind the pulley ribs before applying force.
The center screw is difficult to turn.
The threads may be dry or debris-filled; clean the screw and apply a small amount of heavy-duty grease to the threads.
The tool does not fit behind the pulley.
Check if there is sufficient clearance; if the pulley is pressed flush against the engine block, the low-profile arm may still require a slight shift in angle to catch the edge.
Pros and Cons

- Compact form factor excels in tight engine spaces
- Sturdy construction prevents tool bending under high torque
- Black phosphate finish offers superior corrosion resistance
- Adjustable design fits a wide range of vehicle pulley sizes
- Minimizes the risk of damaging expensive engine components
Cons
- Not intended for heavy-duty harmonic balancers
- Requires manual adjustment which can take time on seized parts
- Limited to ribbed drive pulleys only
Setup, Compatibility & Care
Setup: Before use, ensure the engine is cool and the belt tensioner has been released to remove the drive belt. Select the correct tension by tightening the knurled screws against the pulley flange to secure the arms.
Compatibility: This tool is compatible with most standard automotive ribbed crankshaft, alternator, water pump, and AC compressor pulleys that utilize a ribbed belt drive system.
Care: After each use, wipe down the tool with a clean rag to remove grease and debris. Because of the black phosphate finish, store the tool in a dry, moisture-free environment. Periodically check the threads of the knurled screws and apply a light machine oil if they become stiff or gritty.
