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.

No, this tool is specifically designed for ribbed auxiliary and crankshaft drive pulleys. It is not designed to pull large, high-torque harmonic balancers.
The tool features a 3/8-inch drive, suitable for standard workshop ratchets.
Yes, it is designed for pulleys associated with ribbed serpentine belt systems.
Yes, a hex Allen key is included in the package for necessary adjustments.
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.
Ensure the knurled screws are fully tightened and the arms are seated deeply behind the pulley ribs before applying force.
The threads may be dry or debris-filled; clean the screw and apply a small amount of heavy-duty grease to the threads.
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.
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.
