Crank rebuilding. I am looking for how to's, what has and hasn't worked.
Welding cranks, pros and cons.
Bearings availability, quality.
Measuring, jigs, alignment, presses, other methods for splitting, assembly.
I am thinking the cheesy 12 ton HF press I have won't be up to the job and there isn't much room between the beams. The big press will allow the flywheels to fit between the beams.
Maybe tooling to use a bottle jack with the wedges like mrriggs uses?
So what have you done, thought about, heard?
It would be wonderful if Hugh chipped in his two cents on this.
I have one crank with a bent rod that is good for experimenting.
Tried separating the flywheels of the bent rod by driving a pair of cold chisels between the flywheels that just dug grooves in the chisels, flywheels didn't budge.
It seems when pushed hard the crank likes to spread. What joint usually moves?
Ideas or measurements while the crank is still in the engine?
Thought this might become the crankshaft tech thread if the info flows in.
