Is the bolt in the harmonic balancer threaded to the right or left?

Use a wedge in the fan belt to lock the harmonic balance from turning.

Looking at the front of the engine, the harmonic balancer turns clockwise when running. You will need to turn the bolt anti clockwise as it is a normal right hand thread.

Right hand thread righty tighty lefty loosey. some require a impact wrench 1/2 or 3/4 drive to loosen if either not available the install socket with breaker bar leaving 6 inches of slack between bar and frame crank engine sometime this will loose bolt. you hear a BIG bang as it loosen.

It will be a normal RH thread but TREMENDOUSLY tight, and maybe with Loctite as well. You should use a powerful rattle gun (impact wrench) to get it off.

Hi...I believe it is right handed thread. I don't know if you have the following but you might want to check this out:

The harmonic balancer should loosen in the CCW direction. Turn the bolt to counter clock wise direction.To tighten the bolt turn in clock wise direction. -------------- This should help.Thanks.Helpmech.

it is left hand thread

You remove the giant bolt, then you use a harmonic balancer puller, which essentially bolts up rather than using claws to grab. The bolts of the puller go into the pulley fastening bolt holes.

Something must happen to protect the crank threads, a spacer, using the retainer bolt, or whatever, just do not kill the threads.

it would be a normal right hand thread bolt. Righty tighty lefty loosey.
