I used a harbor freight 20 ton shop press to press apart a crank. The big end bearing is a fairly common size you can buy fron a bearing house.

I'd probably have to find a machine shop or a garage to press it out, then press it in?
Off to the harbour freight website for now, just to look.

Thanks.

PS, might be able to rig something up with a bottle jack, must it be
at least 20 tons?

I don't know about that, but they don't just jump apart lol. It takes some force. You could probably make due with a 12 ton press, but 20 ton is easier.

It's the satisfaction derived from fixing your own chit and making it work, not just buying new parts and slapping them on.

And spending the least as is possible plays a factor as well. It's not like I am going to pay a lot of money to fix a 35-40 dollar crankshaft, unless it's the only path to satisfaction.
