Oil pump seal / O ring question
On illustration 104-01 Pos. 2 is a seal. Pos. 5 looks like an O ring they say is supposed to be 28 x 2, 58. The only O rings I have that are close to that measures 22id x 32od and about 6mm thick. Is this O ring supposed to streached this much? I have another O ring that measures 48id x 58od and about 5mm thick but doesen't seem to fit anything on the pump. Am I measuring these thing right?

the diagram is a little confusing, but i got it figured out with the help of rennlist.
the seal (#2) measuring 38x52x7 is a brown seal that looks exactly like the balance shaft front seals. it fits right inside the oil pump mating surface, sealing the oil pump to the crank.
the sleeve (#4) is the splined washer that fits inside the oil pump, with a beveled edge along the inner edge of the sleeve. next is a thin black oring (#5) that should fit inside this beveled edge, and match exactly the diameter of the crankshaft. you should not have to stretch anything!! finally, a flat washer (not shown in the diagram) mashes against the oring to seat it, and the crank pulleys seat up against this flat washer.
hope this helps
