It's those "nasty belt oscillations" that I'm worried about. This is definitely a 3-groove pulley, and it's definitely out of whack, at least horizontally. I certainly have never removed the pulley on this VWoC remanufactured engine, but maybe the PO did for some reason. It doesn't look like the kind of thing you'd do for fun. I'll try tightening the belt down some more but I've always been afraid of killing the bearings that way. Both Bentley and Haynes are near useless on this point: the belt is supposed to deflect 10-15mm when pressing "firmly" with thumb, but what does "firmly" mean? Arnold says one thing, Maria another. Vast difference. Yeah, this is a primitive design, with the alt/wp belt contacting maybe 20% of the drive pulley. It seems like to make it work you have to tighten the belts way more than you would with greater contact surface, leading to...premature bearing failure. I bet some ingenious guy could come up with an idler system that would help us out. Any takers? |
