I think the French military might have ground the cranks oversize on the thrust faces and had access to oversize bearings to suit.
I have a crank with a damaged thrust face. Can someone give details on the welding process to build up the thrust face?
For example, what type of welding? Mig? Arc/ what type of wire or rod? Special gas?
If normal mig welding and wire I could try myself. Ditto if arc if I know what rods to use.
Thanks for the input so far..

Crank welding is done in a crank welding machine by the submerged arc method. Basically it is an automated wire feed type where the actual arc area is submerged in a special granular powder while welding.
Pre-heat and controlled cooling are part of the process.
