94 Mits Galant - nearly 150k miles and wearing Timing issue

Hi there, the ol' Galant is close to 150k miles. We recently began having problems with belts squealing and all belts were starting to show wear. It got to the point the alternator wasn't charging the battery. So we took it in to change all the belts and figure better do the timing belt and all while we're at it. Well I just spoke to the mechanic and he said that the pulley belt? the teeth were stripped off of the old belt and he wasn't sure what was causing. Me not knowing much about it, I figured it might have been normal. But he didn't seem to concerned about it, other than he hoped the "shaft" wasn't bent. Is it typical for the shaft to bend from worn teeth? Please explain this to me. I'm a real dummy when it comes to pulley, belt, shaft. Would it be typical for pulley belt teeth to wear as he explained? *note: I'm not questioning mechanic know-how, he's a great guy and I trust him* this is for my knowledge.

Thanks in advance, Jennifer

A more typical "while we're at it" is the water pump, which is hidden behind the timing belt, and the timing belt tensioner pully.

I don't think there is such a thing as a pulley belt. It sounds like you've combined a couple of things he told you.

After 150K miles, the timing belt will be worn. Maybe he noticed an unusual wear pattern of some sort. The timing belt goes between the crankshaft, the camshaft(s), and the oil pump. If any of these are not true, the belt might experience more wear on one side or the other. If the crankshaft or camshaft gears are out of true, I imagine you would have worse problems on your hands than a worn belt. I guess he might suspect the oil pump is screwed up.

You might also have him check the tensioner. The tensioner is a little hydrolic ram that pushes the tensioner pully, which keeps the timing belt tight as it stretches. I had to replace a relatively new timing belt because the tensioner sprung a leak and the timing belt got loose and started slipping. A slipping timing belt will cause the engine to run poorly at low rpms and eventually stop working altogether, so this is unlikely to be your problem.

Just realized there is another belt in there the mechanic may be talking about: the balance shaft belt.
