also the rubber in between the damper pulley has come out half way so it is damaged, im goin to trim this a run to hot springs then change it out when i get back, or do i need to change the damper to prevent certain problems?

Is the entire balancer backing out....or just the outer ring? There should be a bolt in the center of the balancer that secures it directly to the crank. If the whole balancer has backed out, either the bolt is missing or loose. If the outer ring of the balancer is shifting, then it is time to replace it. I'd do this as soon as possible especially if it is throwing belts.

I really wouldnt recommend it. If its working the outer part of the balancer off, then essentially its shot. Chances are it will throw a belt at the worst time (middle of the night on the highway). But more then that, if it starts a wobble, it can be extremelly hard on the crank and bearings.

They're real easy to replace with simple cheap tools. I just did mine last month. Be sure to get a new crank seal and clean up the area well where it goes into the block. I dont remember what the torque is on the bolt, but it doesnt require a lot. The balancer is keyed and the bolt acts as a retainer. You dont want to break it off in the end of the crank.

I had to lightly tap mine on far enough to get the bolt started. Once its threaded, it will press the damper on the shaft as you tighten it down. Be sure you dont strike against the outer ring, hit dead center with light taps, to much force can damage the crank shaft components.

When you remove the old damper, use something between the puller and the end of the crank....an old socket works good. Some of the cheap pullers will literally try to screw themselves into the end of the crank as you are tightening the puller.
