did you take off that gear yourself before? suggest you buy new, all 3 pieces, something could be warped or you could have damaged the teeth on the gear if you removed it.

did you put the right washer on? and on the right way? I know its cupped on the edges on one side. Then HAVE to be installed as well, I forgot one once on the front and my timing belt starting walking off.... glad I caught that before it was too late.

get some pics up.

iirc the flat one goes behind the gear the the curved one infront with the curved face, facing away from the gear.

Sounds right to me. He might have reversed the first one causing the belt to grind against it.
