I just purchased this Mac 91 engine and it has this style of connecting rod bolt. I think it's a RIBE drive type. Any idea where I can find a socket to fit it?
That crank looks like a full circle crank that was ground to clear the stuffer. Should of been the other way around. Doubt it was rubbing the stuffer, would of had the exhaust note of a drum set.
Hi Rob, Do you know of a company selling the 101 splined rod bolts? Here is a little info on the tools for them. The l-handle and the socket were made by Allen wrench company. Part # 1620-09 for the 1/4" socket. Part # ST1620k-09 for the l-handle with the socket on the short end. Maybe somebody can find a stash using the part numbers. Go fast and have fun Paul
you should seriously consider ditching that crank or replacing the outer ring of the circle. there's a clearly visible crack on the top ring encircling the crank bell.. that's ready to let go and it wouldn't go well for the inside of your motor. the conn rod bolts have become a problem to get. several people are shopping prices to find a source that doesn't cost 40 bux each. dave l
