CRANKPIN
The crankpin that joins the flywheels and carries the connecting rod big end inside the crankshaft assembly.
This is the crankpin, the shaft that connects the two flywheels and gives the connecting rod its bearing surface inside the crankshaft assembly. It's a core piece of the crankshaft build, sitting between the flywheels where the con-rod big end rides on it, and it's what turns reciprocating piston motion into the rotating motion that drives the rest of the engine.

The old book number for this one is E4999, which just tells you it's been in the parts system a long time under the letter-prefix numbering before the shop switched to the current format. Our catalog record only shows this part turning up once, tied to the crankshaft and timing gear figure.
Because the record is thin on this one, we'd want to confirm exact fitment against your specific engine before ordering. Crankpins are matched to their flywheels and the rest of the crank assembly, so bring measurements or the old part if you have it when you call the shop.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
