davecara Posted May 15, 2020 Share Posted May 15, 2020 Can anyone ID what this is from? It’s 750 I think and the shaft is hollow so I’m thinking slabby? Its going in B12 cases but that’s another story... Quote Link to comment
Nik Posted May 17, 2020 Share Posted May 17, 2020 (edited) Yes, slabby. Identified by the fine splines on the clutch side. Later shafts had coarser splines. Note that you will not find an 1100/1200 clutch basket that fits the fine splines. I put a similar box in my first 7/11 (powerscreen engine in slabby). At the time, 1100 engines were scarse, and little was known about which models had what shafts/splines, so I had a tool shop reshape the fine-splined shaft with coarser splines (by spark erosion, the tool shop where I work). I have run it since 1991 and it works fine, but I guess it would cost a fortune today and it's easier and better to use a later shaft with the coarser splines to begin with.

davecara Posted May 17, 2020 Author Share Posted May 17, 2020 I may put this back on the shelf and persue a full motor rather than chuck together a bitsa! Quote Link to comment
