I’m working on a 57 Golden Javelin right now, and I need the O-ring that goes in the seal carrier on the lower end of the crankshaft. I show it to be a 304098. I can’t seem to find one anywhere. Anyone know the dimensions of that O-ring? Our local dealer usually has many OMC NLA parts, but no luck there either.
I’m pretty sure, but not positive, that the 304098 O ring has been replaced by 302540, which measures 1 X 1 1/4 X 1/8. Then there’s the later square O rings to replace the round ones.
Thanks for the replies guys. I did end up locating one of the O-rings finally. Frank, I think I’ll order some of the quad rings you mentioned from Mcmaster Carr.. are they the ones mentioned in the other thread titled ”O-rings do we have a chart”? Thanks!
