I have a question regarding crankshaft terminology and I'd
like to hear your opinions.
As we all know, originally there were cast & forged crankshafts available
from the factory. Cast cranks are obviously just that - cast.
Forged crankshafts start life as a rough casting, then go
through the forging process to compress the steel and make
it inherently stronger. So, is it correct to refer to
forged crankshafts as a casting ( eg. this crankshafts casting
number is '7115 ), or should that '7115 be the forging number?
For those that know, are the part numbers on the forged
cranks ( eg. 6223, or 7115, or 7118 ) originally cast in to
the rough castings, or added during the forging process?
I often hear people refer to casting numbers when they refer
to forged crankshafts. I just want to know if this is correct.
Obviously, neither of these variants take into account billet
crankshafts. But they are another topic altogether.
