Powerbuilt Harmonic Balancer Puller & Installer Kit 22-Piece — Cars & Light Trucks, Threaded Adapters, Hard Case

The Powerbuilt Harmonic Balancer Puller and Installer Tool Set (648637) is a complete 22-piece kit designed to safely remove and press-install threaded harmonic balancers on cars and light trucks.

This heavy-duty set collects the most commonly required removal and installation pieces into a single hard-case kit so you can service crankshaft pulleys without improvising parts. Every component is sized to fit modern passenger vehicles and light trucks that use threaded balancer holes, and the set includes metric and standard adapters for broad compatibility. The tools meet or exceed ANSI standards and are backed by Powerbuilt's lifetime warranty for workshop peace of mind.

How does this kit remove harmonic balancers?

The removal side of the kit uses a combo yoke with center screws and pointed removal pieces that pull the balancer straight off the crankshaft, minimizing wobble and avoiding flange damage. It includes threaded center screws and bolt pairs to match various crank hub patterns so removal is controlled and even.

• Combo yoke for even pulling force
• 5/8-in x 5/8-in national fine center screw and center point piece
• Multiple bolt pairs to engage different threaded hole patterns
• Hard storage case to keep parts organized

What parts are included for installation?

The installation components let you press the harmonic balancer back onto the crankshaft using a thrust-bearing assembly and forcing nut, delivering steady, aligned seating without hammering. A jaw nut and center screw supply controlled push force while adapters allow fitment to numerous shaft and balancer thread sizes.

• Thrust bearing to reduce friction during pressing
• Forcing nut and jaw nut for controlled installation
• National fine center screw used in both removal and install operations
• Adapters for metric and SAE threaded balancers

Which adapters and thread sizes are covered?

This kit ships with a comprehensive set of adapters so you won’t need aftermarket modifications for most passenger vehicles. Included adapters cover several metric pitches and common U.S. sizes, enabling compatibility across many engine makes and model years.

• M12 x 1.5, M14 x 1.5, M16 x 2.0 metric adapters
• 7/16-20, 1/2-20, 9/16-18 SAE thread adapters
• 3/4-16 adapter for additional coverage
• 22-piece total kit arranged for removal and installation tasks

Is this tool set durable and safe for workshop use?

Powerbuilt designed the components to meet or surpass ANSI criteria so they hold up to repeated professional and DIY use. The included thrust-bearing and machined nuts ensure smooth operation under load, and the storage case protects parts when not in use.

• ANSI-compliant manufacturing standards
• Lifetime warranty from Powerbuilt
• Machined screws and nuts for reliable threading and strength
• Organized case reduces risk of lost pieces

Who is this for? The Powerbuilt 648637 kit is aimed at mechanics, fleet technicians, and well-equipped DIYers who regularly service crank-driven accessories on cars and light trucks. If you work on engines that use threaded harmonic balancers and prefer an all-in-one, ANSI-rated solution with metric and SAE adapters—this kit delivers the parts and durability to perform removal and installation without resorting to improvised hardware.
