lopez Posted May 6, 2017 Report Share Posted May 6, 2017 Mains on my Rev 3 are in an awful state, it sounds like a stone crusher. What's the job like to do? I've never rebuilt a 2 stroke engine. I have a flywheel puller but not a crank case splitter - essential or just desirable? Quote Link to comment Share on other sites More sharing options...
bilks Posted May 6, 2017 Report Share Posted May 6, 2017 (edited) I done one few yrs back not too difficult,didn't use a crankcase splitter only flywheel puller. You can download this engine manual which which is for the EVO but basically same engine. http://www.betausa.com/sites/default/files/pdf/2012Support/Service Manuals/Mototrial/2009-2012 Evo 2 stroke Engine.pdf Edited May 6, 2017 by bilks 1 Quote Link to comment Share on other sites More sharing options...
dadof2 Posted May 6, 2017 Report Share Posted May 6, 2017 The Rev 3 is easy enough to do. You need a flywheel puller and a clutch holding tool. I can't remember exactly what I used them for but I also have a piece of heavy flat steel bar to lay across the split crankcase and a steel bush about 30 mm long 30mm OD and 25mm OD. Probably something to do with pulling the bearings in. Quote Link to comment Share on other sites More sharing options...
