OEMTOOLS Harmonic Balancer Puller Kit — Adjustable 3-Jaw, 4 Forcing Rods, Compact Case

The OEMTOOLS 25090 Harmonic Balancer Puller Kit is an adjustable 3-jaw puller set built to remove engine harmonic balancers and crankshaft pulleys in tight engine bays without radiator removal.

This compact kit brings a pro-level solution to harmonic balancer and pulley removal by combining spring-loaded jaws, four forcing rods of different lengths, and an organized carrying case. It saves time in common service tasks across many domestic and import engines, fitting GM, Ford, Chrysler and Mitsubishi pulleys. The design emphasizes secure grip, reach options for different crankshaft set-ups, and portability so you can keep the right tool on hand in a home garage or a professional shop.

How does the adjustable 3-jaw design make removal easier?

The three jaws center around the pulley for balanced extraction, reducing the risk of slippage or damage during pull. Spring loading keeps the legs held in place while you align the forcing rod, so initial setup is faster and more reliable than non-retaining pullers.

• Three jaws provide even force distribution around the pulley
• Spring-loaded legs lock position while you prepare the pull
• Adjustable spread fits a range of pulley diameters

Which engines and scenarios will this kit handle?

The kit is engineered to work with many GM, Ford, Chrysler, and Mitsubishi applications and is especially useful when radiator removal would otherwise be required to reach the crankshaft pulley. The included forcing rod length selection helps you tackle shallow and deep-set pulleys without jury-rigging extensions.

• Compatible with common GM, Ford, Chrysler and Mitsubishi pulley designs
• Four forcing rods (4", 5-13/32", 6-1/2", 7-13/32") cover tight or deep placements
• Saves disassembly time by enabling pulls without removing the radiator in many cases

What features improve durability and workshop convenience?

Components are built for repeated use under automotive shop conditions and store neatly in a robust case that protects parts and speeds selection. The case keeps the forcing rods and jaws organized so you can verify contents quickly and move the kit between work areas.

• Hardened forcing rods resist bending under extraction loads
• Sturdy carrying case protects components and simplifies storage
• Compact footprint fits toolbox shelves or tool carts for easy transport

How do I pick the right forcing rod and set up the tool?

Select the forcing rod that allows the puller center screw to engage the crankshaft thread without bottoming out or contacting the oil seal. Secure the jaws around the pulley edge, confirm the spring-loaded legs hold, then apply even torque to the center forcing screw while keeping the puller aligned.

• Choose the rod length that positions the screw squarely on the crankshaft nose
• Verify jaws seat evenly around the pulley before pulling
• Turn the center screw slowly and keep the puller straight for safe extraction

Who this is for: The OEMTOOLS 25090 is aimed at technicians and DIYers who need a reliable, portable harmonic balancer and crankshaft pulley puller for service on common domestic and select import vehicles. If you frequently work in cramped engine bays, value tool durability, and want a kit that reduces teardown time and keeps parts organized, this puller set is a practical addition to your toolbox. It’s not a vehicle-specific specialty tool—its adjustable jaw design and multiple forcing rods make it a versatile choice for general engine repair and maintenance tasks.
