Crank pin for crankshafts with a width of 47mm，as used in Vespa T5 models and in Quattrini cases for Vespa Smallframe models.
The crank pin has a lot of work to do.
It connects the two webs of a crankshaft.
Its centre serves as a bearing for the connecting rod.
The connecting rod not only rotates on the journal at engine revs，it also changes direction twice per rotation.
This means a lot of stress for a small component.
To prevent the webs of the crankshafts from twisting，the crank pin must be precisely dimensioned.
A simple part whose quality is crucial for the durability of the engine.
We offer crankpins in very good quality individually.
They can be used to repair or rebuild crankshafts.
