Hi all please could someone help me, are dt175mx crank cases machined as a pair at the yamaha factory or can they be interchangeable.

The reason i ask is that i have two sets of cases & would like to interchange them to make one good set

Many thanks in advance, kind regards Ronnie

Hi Ronnie, well I don't see why not, back in the day I swapped out a Triumph crank case just to keep the original engine number still leaked like a right bastard but then they came out of the factory like that! Just make sure they are straight, a large piece of glass helps with that, then at worst use a "SMALL" amount of gasket seal as a belt and braces approach.
