Cracked S6/T6 Crankcases. Common Problem?
« on: 14 May 2019 at 06:54 »
OK, so our two S6s both have cracked crankcases, in exactly the same position.  One has been repaired, one (mine) has not --- the T6 is not cracked.  Is this a common problem / weakness?  At some point I will have mine repaired, but at the moment, the barrel and clutch ring seem to be holding it all together.

I don't recall others reporting a fracture there (or seeing same before), though two with the same issue does suggest a trend. If it is holding fast, perhaps not wake a sleeping dog. Douglas aluminum can be truly awful to weld due to porosity and impurities. You will have to re-skim all the joints to true it up, and sleeve and bore the bearing journal round as that amount of welding is sure to distort it. Not a minor undertaking!
