REEL ADDICTION Posted December 29, 2012 Share Posted December 29, 2012 I was thinking of ordering a new granite triaxle dump was wondering if anyone has had any experience with the m drive or should I just stick to an allison Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/29081-m-drive-or-allison/ Share on other sites More sharing options...
rick harper Posted December 29, 2012 Share Posted December 29, 2012 If you are clutch dependent to get into some places stay with Allison. Mack will not approve for dump and its not offered in the GU series.

granitefan713 Posted December 30, 2012 Share Posted December 30, 2012 I've been told the MDrive would be perfect for a dump truck, but as Rick said, it's not offered in the Granite due to the agreement Mack has with Allison. You could get creative though and order a Pinnacle axle forward (CHU) as a chassis and do a dump truck that way, I've seen a few pop up on TruckPaper like that, but your not getting a true "vocational" truck that way.

rsb502 Posted December 30, 2012 Share Posted December 30, 2012 I don't think an m drive would be a good fit for a dump truck, an Allison has smooth clutchless power application perfect for a dump truck, with an m drive you would never get the smooth low speed starts and back and forth operation needed in tight places, spreading rock, working with a paver/milling machine. I know people that tried auto shift manuals with centrifical clutches and they couldn't get the performance needed it was either disengaged or moving too fast, there's no slipping the clutch in LL to keep slow for milling/paving,the Allison is proven in off road use in thousands of refuse, concrete, and dump trucks all over the country.

It is a TWIN COUNTERSHAFT unit with TORQUE CONVERTER (hence the "TC" designation) 10 Speed AUTOMATIC for tractor trucks."The new Allison TC10 TS is ideal for distribution applications where a tractor-trailer splits its work cycle between city and highway conditions.

granitefan713 Posted December 31, 2012 Share Posted December 31, 2012 As of earlier this month, the M-Drive was still unavailable in the Granite, according to the local salesman. The ones on TruckPaper are missprints. If you notice, they are all from the same dealer, Nuss Truck & Equip., and if you look at the interior photos, they have Allison shift pads.

rick harper Posted December 31, 2012 Share Posted December 31, 2012 You can spec a CHU with an M Drive and have a dump body installed. But, if you have a failure on the M Drive, Mack could and Probably will deny the warranty claim and have all legal recourse to deny the claim. So, with that being said, do what you want to do.

rsb502 Posted January 1, 2013 Share Posted January 1, 2013 without a torque converter I doubt an Mdrive would be right for a dump truck I know I used to have to creep off road and while paving/milling I havent driven one yet but I dont see how you could get that slow speed performance with a centrifical clutch. I think an M drive in a road truck would be great though, that or a Mack 18 speed and MP8 505 with 3.65rears for me if I was to order a new CH.
