This had its teeth churned up already and was giving me a squealing belt before the swap. I know you can get a replacement tensioner, my problem is that the #10 bolt is bent or fused in the alternator housing so I wont be able to get my wrecked adjuster off and a new bolt in
Would I be wasting my time looking for the correct alternator housing to save my unit, or just find a second hand one.... Anyone had any experience trying to get the big bolt out.
See my pirate tactics 'fix' for my rubbish adjuster to get me home. copper washer was a bad choice... slipping :
