ws721 Posted December 30, 2014 Share Posted December 30, 2014 What is the number designation for a E9 powered MH? 613 means E6 power correct? Quote Remember if it's got a hood it's no good! Link to comment Share on other sites More sharing options...

ws721 Posted December 30, 2014 Author Share Posted December 30, 2014 Hmm. Ok they aren't like a Cruiseliner where the model number designates the engine? Quote Remember if it's got a hood it's no good! Link to comment Share on other sites More sharing options...
kscarbel2 Posted December 30, 2014 Share Posted December 30, 2014 Hmm. Ok they aren't like a Cruiseliner where the model number designates the engine?Exactly, the model number for an MH indicated the engine supplier (Mack, Caterpillar, Cummins or Detroit Diesel), but not the specific engine model.

ws721 Posted December 31, 2014 Author Share Posted December 31, 2014 I knew the 2nd digit ment the engine supplier but I was hoping the 3rd digit ment the size of the engine like a Cruiseliner. My truck is a 721 which means its a EM9. If it was a 722 it would be a E9. So what im hearing is you cant tell what size engine by the MH model? Quote Remember if it's got a hood it's no good!
