Vladislav Posted 2 hours ago Share Posted 2 hours ago By very simple reason my "bet" the engine is E6-350 Econodyne. I have one in a 1988 R-model with similar injection pump. The "bet" is due to the 9-speed transmission used. Mine has the same. You don't need 9 speeds behind a Maxidine since its torque curve works well with just 5 speeds. I have another R-model also 1988 made which has T2070 7-speed transmission. Its ratios are similar to T2050 5-speed but have two "low holes". There's a similary rated T2060 6-speed and T2080 8-speed. All trio has first 5 gears spread much wider than "multispeeds" T2090, T2100, T2110, T2130 and T2118. Wider gear steps are aimed to serve with Maxidyne low torque curve engines. Ok, that my other R-model has its engine stamped as EM6-300L. Almost as Keith described regarding his DM. It's a bit easier to identify R or DM since E6-350 would be R/DM688 model and EM6-300 would be R/DM-690. That's what I have on the door tags. RW's are all 613 or 713 with Mack engines so no clue up. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/76210-mack-e6-4v-hp/page/2/#findComment-587309 Share on other sites More sharing options...
