Timing belt

i have a 1997 geo prizm that shreds the side of the timing belt. the side next to the engine. do you know what is causing this?

If the timing belt was recently replaced, check to make sure the crankshaft pulley is fully seated onto the crankshaft. If it’s not fully seated, the crank pulley won’t retain the lower sprocket for the timing belt. This can cause the sprocket to float back and forth on the crankshaft. And if it floats foreward the lip on the sprocket will wear on the engine side of the timing belt.


Yes but also check the belt tension-er. This could cause the belt to rub on the front of the engine if it is worn
