Any Mack truck experts in the house?

[Wayne M.]

I have been trying to get this straight for years. Can anyone explain the Mack model nomenclature? I can sort of identify with the models e. g. RD, DM, DMM, LE, MR, etc. but the number that follows makes no sense to me. Is there any rhyme or reason for their number system? In our fleet of LE refuse trucks spanning from 1999 to present, some are LE600's and some are LE613's. I can't detect any difference at all. Is there any good books out there besides the offical "Driven for a century" that Mackshop sells that cover this?

Beats me Wayne. You may find some more info on this site plus plenty of Mack pictures. http://www.hankstruckpictures.com/ Have you ever been to the antique truck show in Macungie? http://www.atca-inc.net/25thannu.htm There is a small Mack museum there next to the fairgrounds. I have not made the show in awhile. Last time I was there they were giving tours of the local Mack plant.

We run 2 CH 613s. The CH 612 is a single axle truck. 613's are tandems. The CLs don't really look any different than the CHs. At least from a distance. Haven't had a chance to look one over.

I have been to Macungie for a working plant tour (It's amazing how they screw a truck together in a few yards and when they hit the key the thing fired like it always ran). I knew about the show, and try to make it- maybe 2005, now I have a fellow mechanic who goes.

All I can gather is the numerical part does have something to do with the axle/ drive arrangment. Other than that,

a ch is a set foward front axle, a cl is a set back front axle.



The new "Granites" are really a CV 613, the Visions are really a CX 613



THe trucks are also available as a xx712/xx713 - usually means stronger frame/axles. Also have heard of xx733 too.

Actually the different nomenclature refers to the different degrees of ugliness. RM being ugly and DMM being the worst. :-laf

 

[bmoeller]

a ch is a set foward front axle, a cl is a set back front axle.

The CHs can either have set-forward or set-back steer axles.

the Visions are really a CX 613

Yep. Nice trucks. Drove a demo '99 in July.

All I know are the B models, the R models, and the DM (offset dumptruck) models. Then there's the Superliners.



Oh, and I forgot... the ones with the radiator behind the engine. They burn gasoline and are hand start. I got to hand crank a friend's 1912 Mack years ago.

You might want to pose this question to Will24, they have been building a Mack truck and may have come across this in their research

I work in the transmission dept. in Hagerstown, if you really want to know i can find out.

 

[E7mack96]

If you work in the Trans dept, then answer this -



Is the Mack T2180 series transmission built by Fuller(eaton) or Is it really a Mack built unit. I know the Mack has triple countershafts.



The units I have that have an eaton 18 speed shift identically to the t2180



By Identically, I mean shift points, trans feel, ect.

F8LDOSE, if not big trouble I would appreciate if someone there knows. Do you work on the line assembling those transmissions?



It seems like the first digit might be the class (6,7 or 8) Most of our trucks are 600, 613, etc and they have 19K front axles and 12. 00R20 rubber, so I would imagine they would be lighter duty than something with a 22K front axle and larger rubber.

I am by no means an expert, but two of my teachers definitely are! If no one finds out by the middle of january (when I go back to school) I will get some answers. One of my teachers teaches the guys at the factory in Hagerstown about Mack powertrain products, and another writes mack manuals and develops mack training software!

All Mack transmissions are built by Mack, all the parts as well, all gears, shafts, everything except the case are built in house. We're currently making 60 transmissions aday, working 7 days aweek, and theres 3 shifts, after the first of the year the want 80 aday, it's a good place to work if you want overtime. I work in the gear dept making countershaft gears. As far as different truck model numbers, everybody is like uh-uh don't know... . Hagerstown is just the powertrain division, they don't do anything else there.

 

[Wayne M.]

That's a pretty impressive amount of units to crank out, espaecially with more trucks using allisons lately.

Thanks Guys, I appreciate the research done here. So far I know it's basically the drive and axle arrangment with how many drive and steer axles there are on a particular model.

 

[Timebomb]

F8LDOSE. . That trans # will be 90 after the first of the year. As of 12-22-04.

Wayne M. if you have any questions here is some people you can ask. E-Mail. -- email address removed -- ,(35 years in transmissions senior staff engineer)or -- email address removed -- (A. K. A. "Gear God" 20 years service) hope this helps. .

 

[F8LDOSE]

Rick, The #'s "will be" haha thats a good one. Kumo's for everybody i guess. 12 hour days are long enough i don't want to work 16 hours days like the block line...

 

[Timebomb]

I'm not kidding. Just wait untill a couple weeks into the new year and then you'll hear somthing about it. The guys out there said with you there it should'nt be a problem at all.
