1996 Isuzu rodeo 3.2 liter wondering which direction to loosen harmonic balancer bolt? CW or CCW? If this motor jumps time is it likely to have bent valves? Would hate to reassemble timing belt to find our it will have to come apart again??

No, the bolt is not left handed. You do need to turn it counter-clockwise to loosen it. You're probably just spinning the engine when trying to loosen it. I use a 6" c-clamp and attach it behind the balancer in a way that the threaded shaft can lodge up against something so the engine can't turn. Then I use a 3 lb rubber mallet and hit the 1/2" drive rachet on the handle, or put a breaker bar on the end of it and work it loose that way. Once you get the bolt off, you will need to use a pulley puller to get the balancer off.
First remove right front tire and support vehicle with a jack stand. Remove splash guard lower portion near the harmonic balancer. Remove all drive belts. First remove the A/C alternator belt. Loosen the 14mm bolt at the front of the belt tenioner and then loosen the tensioner bolt (it is the one that stands out, you use a socket on it.). The power steering adjuster bolt with be gained from the bottom. It has a 12mm bolt head on it. You will break the jamb bolt loose first and then loosen the adjusting bolt. Pull down on the belt the help move it after you've loosened it some.Then remove harmonic balancer bolt (19mm).If the harmonic balancer will not slide off the crankshaft then use a two finger gear puller. Place the harmonic balancer bolt back in the crankshaft but do not tighten it. Leave it about a half inch from being all the way in. Next place the puller onto the harmonic balancer (one finger on each side securely press into the belt groove. The center puller bolt will rest against the harmonic balancer bolt head. Tighten the puller bolt and make sure the harmonice balancer bolt does not turn. The balancer should come off at this point.
