Eubanks crankshaft
I recently picked up a NOS Eubanks crank. It is drilled for oil. I have heard that there may be a hardening issue with these cranks. Does anyone have any experience with them?

I have about 25,000 touring miles on one in a 1930 68B with no trouble.

Re: Eubanks crankshaft
I ran his #1 crank for about 2 years in my speedster, with a 4-port Riley on top. Ran hill climbs etc. It was on loan to me for 1 year as a test mule. I then purchased one from him as a replacement for #1. It is still running well. I'd estimate 80% of cranks in new cars are cast cranks. I didn't put a lot of miles on it, but they were often very hard miles. I also run his cast steel rods in my Bonneville engine, 176 MPH is the best time to date. He quit making such things because of problems getting them machined, no one wanted to do it.

Re: Eubanks crankshaft
I bought from Dan at Turlock swap backin approx 2002.
Joe Sivil has a hand in bldg my Russian B with Dan’s crank. It was taken to a crank specialist for exam/evaluation prior to install in B. This specialist reported that Dan’s crankwas ‘perfect’ ! I’ve run it hard at times and with a harmonic balancer, it does its job very well. |

I have been looking thru notes I have and cannot find the exact material ordered, I still have a ways to go. I know that it is not a very hard material as I had to machine some parts of it on the lathe (fitting into "A" block), Dan then told me the material. Some people have had really good luck with them, it all depends on the actual usage of the car/motor and the proper oiling system. I do not recall anything outstanding over a Ford "C" crank, other than the oil seal area is ready for the 2pc chevy seal and the flange should be stronger than a stk "C" crank. If you do a search for Meehanite iron, you can probably find the alloy/engineering documents. John
