Does anyone know the torque spec for a harmonic balancer bolt on 4bd2 engine from npr Isuzu? I haven’t had any luck finding it.

It will be close but not exact. Being its a harmonic balancer bolt i dont really see the problem in it but the torque will be slightly less than origional because of wear on the threads and very slight stretching of the 9Apps Showbox bolt
