Will this work on my serpentine pulley and harmonic balancer?

Yes. The set includes multiple puller jaws and adaptor sockets sized for both serpentine and harmonic pulleys. Start with the jaw size that seats flush against your pulley—forcing a mismatched jaw risks damage.

Do I need a press or special equipment to use the installer sockets?

A bench press or arbor press works best for safe reinstallation, but you can use a socket and breaker bar with steady hand pressure on simpler applications. The installer sockets guide the pulley straight—forcing it by hand risks misalignment.

What if my pulley has an unusual bolt pattern or a sealed bearing?

Test-fit the puller jaws to your specific pulley first. If the jaws don't seat evenly across the pulley or if it has a sealed factory bearing, do not force extraction—consult your service manual for alternative methods.
