1G Timing belt walk

[Tom Gibbons]

Im doing the timing belt and components on my 6 bolt bottom end with 2g head. The tension is set within spec but when I rotate the motor by hand, the timing belt walks off towards the driver side. It seems to start walking off near the crank sprocket then follow suit on the tensioner pulley and cam gears.

Ive also noticed that the crank sorocket wants to slide off and has even popped off its dowel pin when rotating the engine. I also see that the portion of the belt between the crank sprocket and oil pump sprocket has some sort of weird deflection in it where the side of the belt closest to the engine deflects downward.

All components are brand new. Any ideas?

Dude, you're missing the huge washer that holds the crank sprocket in place. Notice the bolt is sunk in? Install the washer, problem solved.
