4seasons Posted August 15, 2018 Share Posted August 15, 2018 I’m going to look at a 95 and a 97 Mack RD dumps. I understand these are the electronic transition years and would prefer the mechanical. How can I tell? Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/54042-how-to-identify-mechanical-or-electronic-engine/ Share on other sites More sharing options...

terry Posted August 15, 2018 Share Posted August 15, 2018 there are different variations of electronics, from just a electronic throttle to injectors and pump. terry Quote Link to comment https://www.bigmacktrucks.com/topic/54042-how-to-identify-mechanical-or-electronic-engine/#findComment-404149 Share on other sites More sharing options...
Maxidyne Posted August 15, 2018 Share Posted August 15, 2018 Most of the Mack engines of that era were mechanical injection pumps with electronic oversight via an electric throttle and VMAC software.
