Re: Regrinding a 2L crankshaft
No experience with a crank shaft regrind. A lot of guys use reground cam shafts where the most important part is a proper surface hardening and sequence for the process. Many people that do cam regrinds skip steps. From what i have read a flame hardening is always prefered to a cyanide bath.
A re-ground crankshaft will need matching undersize bearings, good idea to have new bearings anyway. I guess I'm curious as to why the consideration of a reground crankshaft. I would think picking up a stock crankshaft would be quicker and cheaper?
However, I will admit I'm always learning and amazed at some of the ingenious things people do that I would have never thought of.

Regrind as a final resort if I can't locate a decent one first
Re: Regrinding a 2L crankshaft
2l cranks are starting to get hard to find. We've had several ground undersize in recent months. Bearing availability is an issue, but even standard bearings are hard to find currently
Re: Regrinding a 2L crankshaft
So they can be reground. Thank you, Mark.
There are quite a few places online to buy bearings... Do most use the same supplier?

The bearings are listed at most of the normal vendors...BUT!!!! They are all back ordered when you actually try to purchase. Luckily I scored some from Csaba.

BTW, I would want a standard (non-reground) crank for a hi-po engine.

Re: Regrinding a 2L crankshaft
Csaba, maybe you could share your experience with him and the forum regarding you issues with the machine shop and 2L cranks as detailed on the other forum.
Re: Regrinding a 2L crankshaft
I was able to find a good standard size crank today. Thanks for your input!
