quote Fishbrick:
At this time the case has not been separated from the lower unit. I bought this engine from the original owner, I think it’s all original, because all the bolts still have the original paint. Since it appears to be all original, I think it still has the original seal on the bottom. So, I’m guessing the seal on the bottom would be in good shape since there is oil in the bottom of the case. Is this plausible???? My goal is to get this running without unnecessary replacements.
Plausible but not probable.
Both O rings have an oily mist bath on one side and since you think it’s still the original one in there, chances are it’s hardened up after 58 years. Knowing there is a fresh and pliable O ring seal on both ends of the crank should give you some peace of mind.
