Angry Swapped cranks

Hi My machinist mixed up my crank with another when it was sent off to be ground.
Both flywheels are 6 bolts, and both are from 7R cases

Not sure if this is the parts numbers

D401 142
D424 782

are these cranks be interchangable ?

cheers

hayden

Hi Hayden..

Not sure what those numbers are but there are a few common 6 bolt cranks that will fit a 7R case. You have either a 66mm non-counterweighted crank, 66mm counterweighted, or 70.4mm

There should be additional numbers on the crank. You can also identify it by measuring the rod journals. If you post a picture of the crank with the dimension of the rod journals someone can tell you what you have.
