The term double od came from way back when some mechanics did gear flips to trucks to get the top two gears to be od, creating a. On the subject of the Eaton 13 speed being a double od, well its not what you think. I always liked the 42" tall tire but the shorter sidewall on the 24.5 seems more stable to me, just personal preference really.

The 11r22.5 on an Alcoa wheel vs a low pro 24.5 on an alcoa is the same height 42" and the 24.5 is actually 2.6# lighter by the books,lol. Did you talk to my Salesman in Stoney Creek? He would probably steer you the same way I would.ġ0-4 bbig, a lot of folks are going to 22.5's round here too.
SE is Super Econodyne which is only available with the M-Drive. Late 2016 is the possible release of the new Cab and sleeper. Currently I am waiting till late 2016 before we purchase anything new from Mack. Sure the M-drive is great and if you guys are planning on leasing the trucks you won't have as much exposure to issues or costs related to an older or trade in value M-drive.
73 final split) Second last hole in high split is 1:1 gearing. If I remember correctly there is no longer a non automated 13 speed Fuller transmission that doesn't have a double overdrive (usually. 5 better with the M-Drive.I need to test drive one to get better idea.Every one I talked to at truck stops down here loves the M-Drive.I'm running a 9200IH now with 13 double OD,3:55,ISX 525 hp,1850 in top gears.We are also looking at Freightliner.The Mack is several thousand cheaper which surprised me.Boss is trying to get a 4 year lease.Several fleets in central Iowa are running 445SE,M-Drive single OD and 2:64 rears.not sure on their mpg.I like your input. Ask yourself.high drivetrain torque, expensive option, low trade in value.Why would you go M-drive? Are going to save that much in fuel?ībigrig Is the 13 OD a double OD?I talked to a Mack salesman up there that said you were getting better mpg with the 445C than the 445SE.Some fleets have told me that they're getting. Over $4000 dollars premium on the purchase price and another hit on the trade in value.yes, in the thousands again$$$$$.

Drivers having to push the brake pedal through the floor to stop from running into the back of a car. I've heard horror stories of the first version I-shifts and there clutch solenoids not disengaging. especially on decels at lights where the clutch doesn't disengage or doesnt down shift/decel and it feels like you are stopping not only the load behind you but a truck that is still under power. I do need to ask, Have you driven an M-drive with a load yet? I have and wasn't that impressed. That spec for us is best because it could be hauling US 80k GVW 4 days of the week and 110k GVW here in Canada the next.īuy the truck you are leasing it for 4 years tweak the spec on the next one if it doesn't do what you want this round. We have been over this before a few times.have we not? Just keep in mind the faster the rear end/direct drive trans combo, the more torque you are putting on the drive line and rear end.Ĥ45C is the way to go and remember, us Canadian guys hauling on US turf haul the same weights you guys do.Ĩ.3mpg hauling 80,000GVW usually down to the Mid-west US from Ontario, Can.Ĥ45C-13 fullerOD 355 Eaton rears on 22.5. Have you decided against the super econodyne option? Mack has alreay done the homework if you go with the Super Econodyne Pinnacle and you should get the best possible mpg with that set up. If your not set on the M Drive and want to get the best of both worlds go with a Mack 318LR or 313LR, or even an Eaton 18 speed transmission there youll get a lower low gear to get you moving near gross so you can still run the higher rear gears and when you pop it into OD your gonna really drop rpm. If you were running closer to 40,000-50,000# all the time a higher low wont matter as much so the direct would give you decent service. Running near gross you will appreciate the lower 1st gear with an overdrive transmission and its unlikely youll ever notice much difference in mileage out of a controlled test setting. Well you get more rear wheel torque with direct drive, any overdrive reduces rear wheel torque and so therefore you have a shot of best mpg with direct but the higher gears are easier to damage and you lose bottom end takeoff.
