Ronnie Hill Posted March 23, 2019 Share Posted March 23, 2019 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 Link to comment Share on other sites More sharing options...
slice Posted March 23, 2019 Share Posted March 23, 2019 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. 1 Link to comment Share on other sites More sharing options...
