I have friends who are selling their boat that has sat unused for a couple of years, and I am helping them get it back in working order. Can anyone advise me about the relative importance of the one inch fine thread bolt at the front of the crankshaft on a Ford Lehman 120? It appears to just secure two auxiliary pulleys that in this case are unused, but it seems an awfully big bolt for just that.
I ask because someone stripped it while trying to turn the engine over by hand after it got corrosion-seized last winter. I got the engine un-seized by other means, and there is nothing being driven by the additional pulleys, so if that's the only purpose of the bolt, I won't bother replacing it, because it's an uncommon size/thread that is not readily available out here in the sticks, but if it has some other critical function, I would want to get a new one installed before handing the boat off to the new owners. Any thoughts?
