OEMTOOLS Harmonic Balancer Puller Kit — Adjustable 3‑Jaw, Spring‑Loaded Jaws & 4 Forcing Rods

The OEMTOOLS 25090 Harmonic Balancer Puller Kit is a three-jaw, adjustable puller set built to remove crankshaft dampers and pulleys quickly and without radiator removal.

This compact kit provides a practical solution for technicians and home mechanics who need reliable access to harmonic balancers on GM, Ford, Chrysler and Mitsubishi engines. It combines spring-loaded jaws, four different forcing rods, and a robust carrying case so you can position, grip, and extract pulleys in confined engine bays with fewer steps and less risk of slippage or component damage.

How does the adjustable 3-jaw design improve pulley removal?

The three-jaw layout gives an even, centered pull on the balancer, reducing wobble and minimizing stress on the crankshaft. Adjustable, spring-loaded legs let you set the tool quickly and hold it firmly while you apply force through the forcing rod.

• Three jaws provide balanced extraction for smoother pulls.
• Spring-loaded jaw retention for secure positioning.
• Adjustable legs fit a wide range of balancer diameters.

Will this puller work in tight engine compartments without removing the radiator?

Yes — the set was designed to function in confined spaces typical of many domestic and import engines. The included forcing rods vary in length so you can choose the correct reach for the clearance available around the crankshaft.

• Four forcing rods: 4", 5-13/32", 6-1/2", and 7-13/32" for variable reach.
• Low-profile jaw geometry for cramped engine bays.
• Works on common GM, Ford, Chrysler, and Mitsubishi configurations.

What parts are included and how do they improve workflow?

The kit contains the adjustable three-jaw puller body, spring-loaded jaws, four forcing rods of different lengths, and a hard storage case. Having the right rod size and secure jaws on hand reduces repeated trips to the tool bench and speeds up harmonic balancer removal jobs.

• Adjustable puller body for multiple pulley sizes.
• Spring-loaded jaws simplify setup and reduce slippage.
• Sturdy case keeps components organized and portable.

How does this kit protect engine components during removal?

Centered, evenly distributed pulling forces help prevent bending or damaging the crankshaft snout and surrounding components. The spring-loaded jaws hold position so you can apply steady, controlled pressure with the forcing rod instead of sudden, uneven pulls.

• Even three-point pull reduces off-center forces.
• Controlled extraction lowers risk to key engine surfaces.
• Multiple rod lengths avoid makeshift extensions that can slip.

Who is this for: The OEMTOOLS 25090 Harmonic Balancer Puller Kit is aimed at professional mechanics, independent shops, and savvy DIYers who work on domestic and select import engines and who need a dependable, space-conscious tool for removing crank pulleys and dampers. If you regularly service GM, Ford, Chrysler, or Mitsubishi drivetrains, want a more efficient removal process in tight engine bays, and prefer a compact kit that stays organized, this set is a practical addition to your toolbox.
