Thanks to everyone who replied on my earlier post. I did find some new cranks for sale but I agree that a cast crankshaft isn't the best thing if the original was forged. Does anyone know of a new crank available that is forged? I have contacted some custom crank manufacturers that make forged cranks but they didn't even reply. I considered trying to buy a quantity of them and then reselling them but they didn't even take the time to say no. If anyone knows of a forged crank that is available I would appreciate it. I did find one used one that has been turned but they didn't know to what size. They want $850.00 for it and it would need shipped. I didn't really want to take a chance on getting it and having it be a size that I can't get bearings for.

I am working on a 1750 with stock horsepower. Do you think I need to worry about a crank ground more than 10 under with the low horsepower of the 1750 compaired to the newer series tractors? I have worked on most of the other Olivers except the ones with the 310 motor. This is my first 310 so I have been a little worried to start with. I know a few people with 1750s with the 310 and their motors seem to last forever with stock horsepower.

We're working on getting them made out of the same material as original, C1046 steel. and they are probably going to have 8 counterweights on them. US made steel forging. been working on it for over a year now, and we're starting to put the pressure on the manufacturer. I'm thinking they're going to be in the 1200-1500 range.

It would be great if you can get them for that price. It might save a few 310 motors from the scrap yard.

As an automotive tech, and comparing this to the CAR crankshafts, I wish you luck getting a low volume, forged crankshaft for $1200-$1500. Especially one made in USA and have this much meat on it.
I hope you get the job done. I"m just not holding my breath.

We're using a existing forging die, and are looking at a run of about 100.

Are you looking to sell it? I won't have any problems getting bearings for that size.
