OEMTOOLS Harmonic Balancer Puller Kit — Adjustable 3-Jaw, 4 Forcing Rods, Slim Jaws for Tight Engine Bays

The OEMTOOLS 25090 Harmonic Balancer Puller Kit is an adjustable 3-jaw puller set with spring-loaded jaws and four forcing rods designed to remove harmonic balancers and crankshaft pulleys in tight engine bays without radiator removal.

This compact, vehicle-compatible puller kit combines stable holding, multiple rod lengths, and a durable carry case so you can tackle harmonic balancer and crank pulley removal tasks quickly and with control. Built to fit many GM, Ford, Chrysler, and Mitsubishi applications, the 25090 aims to reduce setup time and avoid unnecessary disassembly — useful whether you’re a professional mechanic or a well-equipped DIYer.

How does the spring-loaded 3-jaw design make pulley removal easier?

The three spring-loaded jaws grip the harmonic balancer securely, keeping the legs in position while you thread the forcing rod. That hold reduces slippage and the need to constantly reposition the tool during extraction, giving a safer, more predictable pull.

• Spring tension keeps jaws engaged for quick positioning
• Three-point contact spreads load evenly across the pulley face
• Adjustable legs adapt to different pulley diameters and profiles

Will this kit fit my vehicle and tight engine compartments?

The 25090 was designed with common North American and select import engines in mind and includes four forcing rods of varying lengths to clear components that sit close to the radiator or other obstructions. It’s intended to reach crankshaft pulleys without requiring radiator removal in many installations.

• Compatible with GM, Ford, Chrysler, and Mitsubishi engine layouts
• Forcing rods: 4", 5-13/32", 6-1/2", 7-13/32" to match spacing needs
• Slim jaw profile to fit into tighter recesses around the crankshaft

What components are included and how do they help my workflow?

The kit ships with the adjustable 3-jaw puller, four forcing rods in stepped lengths, mounting hardware, and a molded storage case. Organized storage and clearly sized rods speed setup and limit time spent hunting pieces — especially useful during repetitive or fleet work.

• Adjustable 3-jaw puller for versatile grip on pulleys and dampers
• Four forcing rods for reach across varied engine configurations
• Sturdy case keeps parts protected and sortable between jobs

How should I use this puller safely and avoid damage?

Center the tool on the crankshaft, engage all three jaws evenly, and turn the forcing rod slowly to extract the balancer. Use steady, controlled force and confirm alignment to prevent marring the pulley or crank snout; threads and jaws are built to withstand normal removal forces when used correctly.

• Ensure jaws sit flush and evenly around the pulley edge
• Apply steady, incremental force with the forcing rod to avoid shock loads
• Inspect threads and mating surfaces before and after use to maintain tool life

Who is this for: The OEMTOOLS 25090 is aimed at professional technicians, independent shops, and experienced DIY enthusiasts who service GM, Ford, Chrysler, or Mitsubishi engines and need a compact, reliable harmonic balancer puller that handles tight clearance situations. If you frequently remove crank pulleys or engine dampers and want an organized kit with multiple reach options, this tool reduces setup time and helps preserve surrounding components during removal.
