buzzerka 0 #1 Posted February 7, 2012 hi guys, I've just bought a real good low hours 16M engine to replace the 12M engine that blew up in my old 312-8, seemed easier than a rebuild and was the right $$. Plus 4 more HP never goes astray. Anyway, the M16 isn't electric start. Didn't faze me that much I figured I'd just bang the starter off the dead 12 on it, Simple as that be motoring again in no time i thought. So I pull the sheetmetal off to find NO ring gear, doh! Which brings me to a list of questions. 1. can I use the 12M flywheel or is it going to be balanced differently. 2. where would I find a ring gear, shipping a whole flywheel to aussie would be killer $$. 3. Are all the electrics, stator ect, different, or is it just a matter of adding a reg/rectifier. 4. If they are different I could just use my 12M elecy, eh? 5. Will the bearing plate off a 12M bolt straight onto a 16M, every frozen bolt snapped off, F@#& !!. If the stuff off my 12hp magnum isn't interchangable, it doesn't worry me that much because I did want to rebuild it a some stage and put it back into my 312-8. I could then replace my onan with this 16M in my 416-H, because the onan is about rooted and I aint spending 1000+ to rebuild that POS. thanks lads. Share this post Link to post Share on other sites

Kelly 1,033 #4 Posted February 9, 2012 yes it's all a bolt on, be sure if you change the bearing plate to set the crank end play with the paper shim gaskets. Share this post Link to post Share on other sites
