ryanwilki Posted February 1, 2011 Share Posted February 1, 2011 Hi all, Im currently rebuilding my DT50MX engine (1993). Im replacing all bearings and seals. Im just wondering how to replace the conrod. Ive been told that the crank will split in half to remove the old conrod along with the big end bearing. Is this right? And will it need to be specially balanced or something? I feel fully confident in doing the top end and my boss has rebuilt 100s of engines (pro engine builder) so i think we can do it, just wondering the best way to do it. Any help is very much appreciated. Thanks Ryan. Also, how much am i looking to spend on parts?? Link to comment Share on other sites More sharing options...

ryanwilki Posted February 1, 2011 Author Share Posted February 1, 2011 So have i been told right that the crank has to be split and balanced? Where is the best place to have this done and how much will it cost? Also, is there anywhere that will do an exchange service? Thanks for the help Link to comment Share on other sites More sharing options...

Thanks for the help Its already balanced, DT50 bottom ends are normally rock solid. I'd be surprised if its gone unless you have done ALOT of miles or run the oil out often. Even big bores don't kill em as the MX bottom end is the same as the m and in europe that was a 60cc 6 or so odd hp monster LOL. Link to comment Share on other sites More sharing options...
