HI All,
Just A correction to my last post regarding Nitriding I said that it normally had a depth of 10 tho
it should have said 10 tho depth of penetration which does not change the diameter of the journal
so if you grind a crank under size by say 10 tho you would still have 5 tho of nitriding left
PS max increase in O/D would be around one tenth to three tenths of a THO most cranks of this size no change at all and a light polish will correct
nitriding is a case hardening process
Cheers
