Gearbox for a Rotax 600 Engine - installed on kart

grabcad

I've developed a gearbox housing for a Rotax MXZ 600 engine. About 105hp on a 102kg kart. The main gears and the clutch are from a Ducati 600; the primary gear is self-developed and machined out of 18CrNiMo7-6. The Gearbox housing was milled on a DMC 1035 and/or on a Flexicam programmed with Inventor HSM. Constructed with Catia v5 R25. Original Datas and Step file are attached. Thanks to GrabCad community for the carbs, exhaust and ignition coils. To protect the files I’ve changed some dimensions which would result in toothaches :) All other dimensions of the engine are quite accurate but measured by hand. Here is the first start: http://sendvid.com/qmaj9hr4 The whole engine was dissambled, installed another igintion, other carbs, other pistons,... and it runs like hell
