youngstown.bulldog80 Posted February 21, 2018 Share Posted February 21, 2018 hello...where would i be able to find service manuals for the older Maxidyne wide power range engines (endt-675/676) and the Maxitorque 5spd/6spd? i've checked ebay and haven't had any luck with manuals that are in-tact and in decent shape. figured someone on here may know of other places to check. i've contacted Mack directly, but they won't reply. thanks!

j hancock Posted February 21, 2018 Share Posted February 21, 2018 Keep checking ebay. Over the years I have bought a TON of Mack paper there. There are vintage paper dealers out there but from my experience they all seem to carry sales brochures vs. repair books. Quote JimIt doesn't cost anything to pay attention.

Mackpro Posted February 22, 2018 Share Posted February 22, 2018 What year model would that engine be? I might have what you need Quote Link to comment Share on other sites More sharing options...
youngstown.bulldog80 Posted February 22, 2018 Author Share Posted February 22, 2018 hello, thanks for your reply....well, two engines would be in mid-70's R models -- an ENDT-675 and an ENDT-676 and one engine from a 1981 R model -- EM6-285. Is the EM6 the same engine as the ENDT's, just newer engine nomenclature? Would that EM6 require a separate service manual? As for the transmissions, two have the 5 spd Maxitorque, and one has the 6 spd Maxitorque (low hole). Quote Link to comment Share on other sites More sharing options...
Mackpro Posted February 22, 2018 Share Posted February 22, 2018 https://macktrucks.vg-emedia.com/InformationListing.aspx?GroupId=536 Is this the engine ? If so Mack still list the manual. I hope the link comes through Quote Link to comment Share on other sites More sharing options...
Mackpro Posted February 22, 2018 Share Posted February 22, 2018 Our oldest engine manual here at our dealership is for the E6 4 valve head. We sometimes have extras for the older manuals but not in this case. Quote Link to comment Share on other sites More sharing options...
youngstown.bulldog80 Posted February 22, 2018 Author Share Posted February 22, 2018 Thanks for the link. There’s 80 results so I’ll have to sort thru them. And yea that would have been great if there were extras there at the dealership. Thank you for checking into it for me! Quote Link to comment Share on other sites More sharing options...
