Turning a crankshaft
« on: July 11, 2016, 11:43:37 pm »
 I have a pair of matched diesels but one has a broken crankshaft. I wondered if anyone can turn me a new one. I will pay a reasonable price
   PM me if you can help.
                                           Thanks John

Hi John,

What engine?

Can you post a photo of the broken shaft?

John....without seeming negative  :o...

I suggest it is a near impossible task to manufacture an acceptably toleranced, replacement crankshaft with hardened with ground journals O0 with a T.I.R of 0.000" & capable of rotating at 15,000 RPM ......cost effectively >>:-(

Would have done it myself but my lovely little 3" Myson got stolen along with all it's kit.Stolen to order from my lock up. The only other thing was a pair of mirror finished pliers in hardened stainless medical equip. Cut through any thing. Scumbags >:-o
