Gambi80 Posted January 13, 2010 Share Posted January 13, 2010 Where's the pictures...??!I think if you have 22.5 tires with that gear ratio it might be a little slow if you run out west...depending on what the cruise rpm for that motor is and how fast you like to go. I've got 22.5's with 3.86 rears and an 18sp...1600rpm @ 72mph. Normally, I don't like to run much over 65, but I don't do much highway driving really.

Mackpro Posted January 13, 2010 Share Posted January 13, 2010 found a truck for a good price need advice on how it is equiped 2007 cxn 613ac 460 p18 speed no overdrive394 gearshow bad do you think it will be on fuelcould you guess at mpglast 6 digets of vin is all i could get 020002That trans does have a .71 overdrive in 18th gear like most Mack trans so it would be OK. Maybe alittle more trans than you need for on-road use. However most Mack 13 and 18 speeds Macks are exactly the same trans except for the shift knob which lets you split the low side. The T318LR is only different from the T318 by having a lower gear in 1 and 2, the rest of the ratios are the same. This truck is probably kinda heavy as it has the 200 series Mack rears.

daveigou Posted January 13, 2010 Share Posted January 13, 2010 Ask the dealer to pull a fuel mileage report out of the ECU. I believe it should have a 13 spd (T313LR). All current Mack & Fuller 13 spds & 18 spds are all OD in the top two ratios.It looks like this truck has 22.5 tires. With 3.94 ratio my gut tells me its legs are a little "short". Also has 200 series carriers.I don't know how & where you run, but for OTR fuel mileage may be marginal. But you as the driver can do a lot to make it or break it when it comes to fuel economy.Dave Quote See my Flickr photostream page http://www.flickr.com/photos/96692978@N05/ Link to comment Share on other sites More sharing options...
Gambi80 Posted January 13, 2010 Share Posted January 13, 2010 I don't think you can have too many gears though... Swap the 22.5's for some 24.5 talls and call it a deal.Maybe clue us in on your driving habits, how concerned you are with weight and overall what you expect out of the truck...besides for it to RUN!

I would be Ok if it had 24.5 wheels as you could go from Lo-pro to tall rubber if needed. Quote Link to comment Share on other sites More sharing options...

Gambi80 Posted January 13, 2010 Share Posted January 13, 2010 On the shifter...a red button is 13sp, gray button is 18sp. I think it's the same no matter what brand of transmission. With the Mack trans the button flips up/down, Eaton it flips forward/backward....if that makes any sense.Pretty sweet lookin ride, by the way.

daveigou Posted January 13, 2010 Share Posted January 13, 2010 For the vin you posted, 20002, it was originally built with a T313LR, 13 spd trans and had 22.5 tires. That would be a plus if somebody already changed it over to 24.5.Dave Quote See my Flickr photostream page http://www.flickr.com/photos/96692978@N05/ Link to comment Share on other sites More sharing options...

fjh Posted January 13, 2010 Share Posted January 13, 2010 were they rite about the 394 gearsThe truck has a vip you can check the trip and average mpg in that screen!Scroll there Quote Link to comment Share on other sites More sharing options...
daveigou Posted January 13, 2010 Share Posted January 13, 2010 Yes. 3.94 is original, that's also the tip-off that it has 200 series carriers. A pedigreed CXN is rare. I also thought I saw that it had a 70" sleeper.Dave Quote See my Flickr photostream page http://www.flickr.com/photos/96692978@N05/ Link to comment Share on other sites More sharing options...
daveigou Posted January 13, 2010 Share Posted January 13, 2010 Also noticed it has an air-ride steer axle. There have also been some issues with those. For one thing, they are not serviceable, if a kingpin wears out, the whole axle goes in the scrap bin.Dave Quote See my Flickr photostream page http://www.flickr.com/photos/96692978@N05/ Link to comment Share on other sites More sharing options...
bts-4120 Posted January 13, 2010 Share Posted January 13, 2010 looks like perfect specs to me tall 24.5 I would want at least 4.17's should run 1518rpms at 65 and 1635rpms at 70mph pretty close to my fuller 13 and 3.70's on short rubber I sure would like the lower gears of the Mack 13 LR and 3.94's Quote Link to comment Share on other sites More sharing options...
cgallamore Posted January 14, 2010 Author Share Posted January 14, 2010 called to recheck some things it has 11r22.5 not 24.5 , acording to the vip 136,000 mile trip showed 5.36 mpg. guy still hasnt told me how much difference he wants,guess ill find out in the morning.
