Right hand thread but very tight,usually need to use air gun or lock engine and use big bar amd socket
SOURCE: is the bolt on the harmonic balancer on a 1995 isuzu rodeo 6 cyl.
i just replaced mine and it loosen to the left...so you will need a impact and atleast 1/2" drive and 140 to 180 psi to break it free
SOURCE: crank shaft harmonic balencer bolt
THe Harmonic balanced bolt is loosened by turning it counter clockwise. It is recommended that you get the special tool to hold the harmonic pulley stationary while the bolt is loosened or tightened. However the bolt can be loosened if you use an impact socket and a very strong breaker bar and place it against a strong part of the frame and just bump the engine over very carefully with the high voltage coil wire disconnected so that the engine won't start when you bump it over with the starter and make sure the socket and the breaker bar are very secure when doing this. I recently bought the special Honda wrench from Snap-On tools and it works great for this, but it's very expensive but it's the only way to hold the Harmonic Pulley sufficiently in order to tighten it back to the recommended torque. Which can be several hundred ft pounds, see the service manual for the exact torque.
