I pulled this out of an old Brickboard post:

"You can set the crankshaft to 0° TDC without putting the lower cover and Crank pulley back on. Just put the keyed rear cup washer and sprocket in place. The cup washer has a small notch that will align with a raised rib or line on the aluminum seal carrier where the crankshaft oil seal is pressed in."

On mine, the rear cup washer has a key on the inner diameter, but nothing either on the crankshaft or the rear of the sprocket that mates with it, and no notch on the outer circumference anyway. The front cup washer on the other hand does have both an inner key and outer notch, with which the above suggested test will work.

Does the way these washers key vary on different vintages/models?


One other question: is anyone else having problems posting pictures to the Gallery? It keeps erroring on me, even though the picture dimensions and size are within to prescribed limits.
