hey Trent here are some pics from the last time I was down at the layout I just took a few of my UP Dash 9's. Ryan

I have got to get back to Chicago to check out the HO layout in the Museum of Science and Industry. My mom is from Chicago and my grandparents and uncle lived in Hammond IN till about 6 years ago. I also like to run long trains the layout in Nolensville is The L.A.&SL the era is late 50's early 60's I have a set of 3 SD-24's to run there but I model modern CSX and UP trains when I can. Ryan

I am into HO scale model railroading actually we are building a 5000sq ft model railroad in Nolensville TN. I have more HO scale trucks than locos I like the light I am guessing you used a single led and fiberoptics they look good I have two of those B model cement mixers. Ryan

I remember them setting the engine load threshold no mph to 100% on ours too they are set low from the factory so you cant run them wide open sitting still . I think that was the biggest cause of the slow throttle response in the AI engine trucks everybody I know had tha set up and it got better in every truck. http://www.idc-solutions.net/MackE-7DieselPerformance.html#MACK ETEC etech performance power chip module go to this web page if you want it to really run they will reprogram your ecm to make up to 150hp over stock a guy here had it done and his truck rear wheel dynoed 486hp that puts it around 609hp flywheel at 80% rear wheel. Good luck with your truck.

II hear ya I got mine done in '06 and it had a super secret program too they wouldnt tell me what they did but it out ran the 460 trucks around here. I wish I knew what the program was but boy it made it come alive, good luck with the ones you have. Ryan

I have seen videos of the Killer Mack of Bonner Farms so many times I can hear it in my sleep that is one seriously bad E-9. I would love to pull in to a truck stop fuel island hitting a lick like that in a on the road truck talk about freaking people out. I just had a 5" straight pipe on the E-9 440hp in the 84 and people hollered at me on the radio and came running over to me in container yards telling me it was missing and to turn it off before I blew it up. Then I would pull the hood and their jaw would drop most of them had never seen a 16 liter V-8 before, the best ones would tell me it was missing then I would leave the yard with the front wheel about to come off the ground leaving a cloud of smoke they wouldnt tell me it was messed up again. Ryan

I actually meant to type 8V71 but Ive got what they call stupid fingers its hereditary. I have a pair of those V-8 emblems and a whole set of Superliner emblems I got kinda crazy on ebay for a while. Now I have a box full of Makc emblems and parts anbody need a E7-460 badge I have 3 how bout a set of econodyne badges from a Superliner got them too , I even have two of the hood ornament mounting bases for the old style r-models. Ryan

I had the same issues with my 04 Granite with the AI427 and the 06 Granites from the fleet I worked for before I bought it they had AI460's with 8ll's and 4:42 rears with tall tires. I can sympathise with the trips to the dealer for nothing I finally told them they could have 4 new trucks back and we would go buy KW's and amazingly they reprogrammed them all and they ran better they even smoked under a load. I bet they are stuck dealing wiht the EPA crap that was there hold up on ours they said they couldnt let them smoke so they wouldnt make much power but when that $500,000 dollars worth of trucks was gonna come back 4 months after they were delivered they found the power in them. I will say this they have to be run to 1800 rpm I hate to do it since I am used to pump engines and early E7's and they run best under 1600 but the AI engines you have to take to 1800rpm before you shift or they dye with a load. I tried to drive mine low in the power band and it wouldnt pull itself out of a wet sack, if you get 74,000 groos on one of those 06 models with the AI460 and let the rpm fall under 1350 youve had it. I wish you luck and heres to hoping they can get the MP8 to run reliably cause the MP7 is gutless too in my book(course I got used to an E9) Ryan

Well one thing is for sure you got to get those darn pete wheels off that Mack somehow geez, you must be one of them red oval guys. I would have made the dealer swap em before I took it home, traitor. lol

I actually just thought about it but my CH had a T2090 w 3:89 Mack rears it runs best around 1600rpm which puts it around 72mph with low pro 24.5 tires if that info helps ya. Ryan

Good info I never knew Fuller made a 2 stick. Ryan

I never knew what they had for a drivetrain but that pic looks like a long hood R model could it be an RS700L or RS600L with a 6V71 Detroit? Ryan

I too am puzzled by the '01 w stud pilot wheels I have never seen anything but school buses with them after the late '90s Blue Bird Buses still had them right up to the mid 2000's and just in the last few years went to hub pilot as standard equipment. I also dont know how you are breaking so many I have run triaxle dump trucks with stud pilots and never broken one, and here in TN we are legal for 74,000lbs gross if that wont do it nothing will. I also like the info on the hubs the ones I have converted were all newer so it was pretty easy to go to the parts store and get the hubs, and I always went to hub pilot from spoke never from spoke to stud pilot. I thought they were the same bolt p[attern for all stud pilots but wasnt sure I know they made 8 lug hub pilots and the front wheel on a front dump cement truck is different than the others so I wasnt sure about different bolt patterns. I hope you have fun with the project its a neat truck. Ryan

The comment about spicers was narrowing the two stick transmissions, they are the only other maker to have a two stick trans and never in a Mack that I know of. I dont know everything about them all thats for sure just the ones I have been around but I do know I have been in a Mack u model with a two stick that had 5 on the main and hi-low on the second shifter and was told by the owner that it was a two stick 5 spd. I have never been in any others but that one with the range on a seperate stick and I have driven an R model w/a 300 and a 7spd that was a 7 spd air shift, the trtxl multi range trannys and the quadra-plex and tri-plex. I am only 31 I wasnt even born when some of the trucks I have driven were built. I will say you know your Mack tranny stuff I might have to call you on my next project truck. Ryan

Does anybody remember the days when Roadway had a blue and orange Rmodels running down the highways they went to CH's for a while heck Roadway ran almost all Mack back in the early days there are plenty of pics of old Mack coe's and B models I think I remember seeing some LJ's too Ryan

10-4 if it has an air shift on the tall one it probably has 4 positions high-low-neutral-rev that would be a TRTXL1070 or 1070B 12spd. Ryan

Wow some good answers there a TRTXL1017B would be a goos one but they are getting hard to find. The t2090 to me is a great tranny but it has a big step from 8th to 9th not good with a little motor and a big load. I think you could find a 13spd mack easier than the 1070 and it will be a lot cheaper, try Weller Reman they keep a great stock of reman trannys with warranty. They woreked with me on swapping one model for another if its something they sell frequently, most places wont give you a core credit for a different tranny than what you buy, if I remember right they are the same length too. Ryan

The CH has a E7-400 vmac 1 (electronic bosch pump engine)Mack 9 spd Mack 3:89 rears on Mack air-ride, it runs good for 17 years old Thanks, Ryan

As far as availability, you have to change your hubs to a stud or hub mounted hub versus the spoke hubs you have now. I have done it before you just get the hubs with the same bearing demensions as the spoke hubs you have. There is another big deciding factor too do you wand the old style three or two piece aluminum budd wheels or the newer style single piece wheels. I dont know if the bolt pattern is the same for the older two piece wheels or not but that is what I would want on that truck if I took the spokes off, keep it in the right era. I dont think it would be too hard to swap no matter what you choose you just have to get out a caliper and get to mweasuring then make some calls or do some internet searching for part numbers. Ryan

I was waiting for someone to point out tha Mack hasnt built their own axles in a long time, they do have a rep at the factory to make sure they get what they want but they done make them. I notidced the post about the axle locks being handy some times but the old air shift is a good strong rear and guess what if your rear brakes are all 30-30's and they are adjusted even, when you get into a sticky situation you can flip in the power divider (which you should have done before you drove into soft ground to begin with) then set the parking brakes put the truck into the lowest gear possible and ease into it if the truck runs like all the Makc dump trucks I have driven it will pull right out. The brakes being set causes the power to go to all of the wheels fairly evenly the way those diffs work they put the power to the axle that can turn the easiest, so by setting the brakes they become a quasi axle lock. I will say this is not covered under warranty and is not advised by techs or dealers but I bewt I have used that trick a thousand times and it works. I do love a Mack rear they are heavy as crap but they hold up where others dont, I worked for a company with one Mack and three petes and two kw's for a while all dump trucks. The paccars with 46,000 eaton rears and the Mack with 44,000 camelbacks with 90series diffs the eatons would break axles left and right in soft ground you didnt even have to try hard but the Mack never broke a one in 200,000 hard miles on construction sites. Ryan

I think you might be on the wrong trail here, I dont know that Mack ever used a spicer transmission and by 87 they were way past the tri-plex or quadraplex two stick transmissions. I would guess it has a 7spd or a 12spd the 7 speed would be one shifter shorter than the other and it would only shift the low-low I think they only did that with a seperate shifter for 1 year model then it went to air shift. The 12 spd has the same ide but the taller shifter has an airshift button on it, it would only use the smaller shifter on the left for low-low as well it would shift like a super ten on the taller shifter. I think that would be what you had in an 87 maybe not but that is probably it, it might be a twin stick 5 or 6 spd but I doubt it and if so it just shifts the range from low to high so you use one shifter 1-5or6 then shift back down and move the other forward then shift 1 thru 5or6 again. I'll check back but if you can tell me what the shifters have on them I can tell you how to shift it(ie: is one tallet than the other and one has airshift button on it) Ryan

I know chrome dont get ya home but I love customized trucks and I dont think I could even drive a plain jane truck anymore. I think the more you do to a tuck yourself the more you feel it is really your truck not just something you do for work I guess it all comes down to what you like in the end and I am attracted to shiny stuff.
