Harmonic Balancer Puller Kit - Heat-Treated Yoke for Pulleys

In this review the OEMTOOLS 37187 Harmonic Balancer Puller Kit is evaluated for both DIY mechanics and professionals who need a reliable way to remove harmonic balancers, vibration dampers, pulleys, and gears without prying or damaging components. The single biggest reason to buy is its combination of a heat-treated, multi-slot yoke and a pressure screw that applies even, centered force so pulleys lift straight off shafts; that design choice reduces the risk of bent shafts or torn seal surfaces and makes removal faster and safer.

Key Features

• Heat-treated yoke: The strong yoke resists bending under load so the tool holds alignment while removing stubborn balancers.
• Four-slot design: The crows foot yoke accepts 2- or 3-hole applications, increasing compatibility with a wide range of pulleys and gears.
• Floating swivel tip: The swivel tip centers on the shaft end to prevent damage to shaft faces while applying steady pressure.
• Included bolts for GM V6: Bolts supplied for GM 3300 and 3800 V6 engines let owners of those engines begin work without sourcing extra hardware.
• Pressure screw with retaining washers: The screw tip holds the puller in place and the washers are designed not to pull through the yoke while torquing.
• Versatile puller use: The kit doubles as a steering wheel and crank pulley puller when the appropriate bolts and pressure screw are used.

Who It's For

The kit is aimed at home mechanics and shop technicians who need a compact, versatile puller that handles common harmonic balancer and pulley removals without resorting to prybars. Its included bolts for GM 3300 and 3800 V6 engines and multi-slot yoke make it useful for those working on domestic cars and light trucks.

This kit is not suited to users who expect to use impact drills with the puller or who need a large, specialized off-road puller for heavy industrial shafts; the manufacturer explicitly advises against impact use and the tool is sized for automotive pulleys rather than heavy industrial applications.

Pros & Cons

Pros

• Sturdy heat-treated yoke that maintains alignment and reduces bending during pulls.
• Multi-slot design for 2- and 3-hole applications increases compatibility across pulley types.
• Floating swivel tip and screw tip keep pressure centered and protect shaft ends and seals.
• Includes bolts for GM 3300 and 3800 V6 engines so fewer extra parts are needed.

Cons

• Some users report mixed durability under heavy professional use, so extreme repeated shop abuse may reveal weakness.
• Not designed for use with impact drills, which limits how some technicians power the tool.

Our Verdict

The OEMTOOLS 37187 puller kit is a practical, cost-effective tool for DIYers and many shop tasks because it combines a heat-treated yoke, multi-hole compatibility, and a centered pressure screw to remove pulleys cleanly. It represents good value for routine automotive work, though technicians with heavy, repetitive shop demands should verify durability for their workload before relying on it as their sole puller.

Frequently Asked Questions

Can this kit remove steering wheels?
Yes; the kit can be configured as a steering wheel puller using the pressure screw and appropriate bolts provided or adapted for the job.

Will the kit work on GM 3300 and 3800 V6 engines?
Yes; bolts for those GM V6 engines are included so owners of those engines can begin removal without extra hardware.

Can the pressure screw be used with an impact drill?
No; the manufacturer advises against using impact drills with this puller and recommends lubricating the pressure screw for easier manual operation.
