[V8] New problem - v8 tb

[Jason Wilkerson]

Dave,
  It looks like your belt rides the same way mine does.  I know the 'lips' on the rollers keep the belt from riding back too far.  But my point of misalignment was about the actual roller or waterpump being tilted, for lack of a better term.  What I mean by this is if the roller is cocked it will cause the belt to want to ride one way or another.  I wouldn't even be worried, but it looks like the belt has done some VERY slight rubbing in the area directly above the damper where the belt crosses over the raised flange on the water pump.  I was actually thinking about grinding that area back slightly, as it is not part that covers the water impeller, it is just a dust cover to complete the back side of the TB cover.  I wish I could take your picture and point to the area but I'm not that good.  Thanks again for the advice and picture.
