Midliner front brackets? Hmm, interesting. Definitely some engeneering was involved. Also I rifled through the net a little and found out CM had 9.27 frame rails. CH rails were 10" tall. I tried to relate that section to any other Mack rail and found no similarity. Could be missprint. But RBM (resistance moment?) was pointed out as 1020000 Lbs in what is the same figure to the rear (straight) portion of a CL600 (RW600) frame rail. That rail is 9.37" tall so again incomplete correspondence or a missprint. Anyway it looks like CM didn't utilize CH rails but its own ones.

Similar to CH,  straight rails. Slightly smaller.

I have a breakdown of the rails I will post up another day.

Is there an easy way to identify the CL Elite limited edition? I have 1 with the same paint scheme

Post up the last 6 digits of the VIN. Has to be a CL613 model. I have a list and I will check.

Thanks for the details, almost new story to me.

A bit more of couriosity, and sorry for that - what are the front spring hangers and spring packs? CH I suppose? Or R? To my understanding CH has different spacing between the springs than an R but the axle beam is probably just drilled a bit different like it was done to MH/RW being basically the same casting used on R's, CH's, MH's etc.

And how are the air tanks and battery boxes arranged? I don't see what was typical for a Mack chassis of the era on your pictures.

Air tanks were mounted side ways (left to right) and only 2 of them. (Midliner 3 tanks front to back)  Battery box is above tanks but space for 3 (midliner 2 spaces) the midliner axle is drilled differently then a CH axle. Spring spacing is narrow and uses midliner front brakets

Pretty interesting. Also taking to account a full size truck chassis (CH) and big wheels its babiness seems doubtful. Ok, smaller engine and shorter hood were probably the goal. But I belive the track was wide and overall weight raiting mostly due to the axles and wheels could be quite high.

The twin screwer on the photo above looks pretty nice. Definitely uncommon thing. What the on-chassis cab mounts look like? If you made any pics of them while working on the chassis please share a bit on here.

Also I can't figure out which truck you fix. Have you the hubs/wheels swapped out to hub pilot? Or is that a different truck, not the one on spokes in the initial pictures?

We changed out the spoke wheels which it was built with to Hub Pilot aluminum disc wheels. Easy to do as these are Mack axles and hubs are readily available. (Mid liners never had spoke wheels as an option)  Same wheel track as Mack R as same axles used on both models. 

The baby 8 was built to be smaller and cheaper then an R model but heavier then a Midliner. It was only available from 88 to late 89. Just over 600 CM422 (single axle Renault power) were built. 

Cab mounts were same as Midliner but bolted to Mack Frame rail.

What is the difference? I see the chassis rails don't look like an R-model stuff. Renault? Or a CH?

Also it has real truck wheels. Did Mack use complete axles or only reworked hubs to fit Budds?

Saw you mentioned the wiring and the air brake setup in the cab. Anymore major points?

Anyway it's an interesting rig. I didn't hear about a CM before. My respect to its rareness, worth to keep in the stable.

The frame is "basically" the same as the CH. (Not Renault) the crossmembers are older single frame R model

Axles were Mack front and rear and available in either spoke or stud pilot wheels (alum or steel)

Engines were Renault (E5) or Cummins 8.3L

Trans was Spicer or Fuller 7 and 9 speeds

Besides the engine option cab shell and some interior parts, hood, everything else on the CM was Mack. 

For those that have seen Midliner wiring/fuse panel, they will recognize the picture I posted of the CM fuse panel.

Complete air system is North American.

Big difference.

Wow, I did not know that paint/decal  scheme was a limited edition.

Only 6 paint colors and 3 stripe color options were available on the CL Elite Limited Editions. I would upload the brochure but it looks like I've reached my max for file uploads.

Yes, the CH was only available with the E7 Mack.

 

The CL originally was available with E7, E9, Series 60 Detroit and 3406 Cat. Detroit disappeared (can't remember which year) and when the E9 and Cat were discontinued from them it was E7 and Signature/ISX Cummins only.

I could be wrong but I think the last years of production the ONLY engine in the CL was the ISX.

I'm lucky enough to have driven all versions.

There were 5 CHs built as a test for a US customer with L10 Cummins in the early 90s. They exist on the Mack parts system as CH633s. Never made it to production and not sure who they were built for.

thier used to be tons of them out here,,they all vanished with time....they were all box trucks,,,and ive never seen one with that extended cab..bob

This is not a (Renault) Midliner CS.  This is a Macungie PA built CM422.  Different trucks.

2 of my favorite Mack's, and The CS midliner is a damn good truck... I wish part's were easier to get here in the states.  I could make half a living fixing the ones in my area..  Thanks for the cool picture...   jojo

This one is a CM "Baby 8" not a CS. 2 very different truck models offered by Mack. Less then 600 of these CM422s built at Macungie PA.

Awesome pic! I have a few Mack CL like that in the exact color and paint/graphics scheme........... but in 1/32 scale 😆 Franklin MInt diecast models.Just beautiful to see it on a real truck.

This CL is one of the few CL Elite Limited Editions built. (Less then 150) My one has the E7400 instead of the E9 that was an available option.

Saw on facebook where UPS has some new Mack Anthems. They look nice. Not sure how big the order was.

They were not ordered by UPS. They are test units that were offered into the fleet by Mack Corporate.  Single screw and tandem.

Anyone have any good grey plastic bumper ends for a CH or CL they want to sell?

No one seems to make or stock R or L ends anymore.

Center section still available from multiple vendors.

Great story thanks for sharing. That red and white IH in the first set of pics is same paint scheme as a company out of Quebec. I just can't remember name. Possibly was from there originally

Guilbault from Quebec.

I have seen some older Macks with Detroit 92/71 series engines and Cummins Big and Small Cam engines in them. Once the engines went electronic did Mack use other than Mack engines??  Did a Series 60 Detroit or N-14 Cummins  ever make it into a Mack??

Series 60 Detroit was only ever fitted to the CL643 chassis from factory. The 12.7L version was available in 400hp and 425hp ratings but only between 1993 and 1995.

The N14 Cummins was never made available for factory order. Cummins only lasted as an option till 1991 in the MH and RWII chassis. You could get up to the 444hp in RWII and the 400 in the MH when Mack stopped carrying them for the 1992 model year. 

Cat 3406B was available in the CL753 starting in 1993 but changed to mechanical 3406C in 1994 which carried till 1999.

Yes, Detroit engines were available in the Ultra-Liner (MH642/643) and RWI Super-Liner (RW643/743......Note: No RW642 or RW742 4x2 chassis were ever built, though they could have been ordered)

https://www.macktrucks.com/-/media/files/museum/model-production-numbers-1905-2000.pdf

Incorrect. The 60 series Detroit was never available in the MH. 

The older 2 stroke Detroits were available in the MH chassis.6V92 as an example.

Only the CL643 was ever available with a factory installed series 60 12.7L.

Wow! rare beast now.  Someone mentioned that the Israel military might have had RD800 AWD and some might have been log trucks. A RM V8 is also very interesting, it seems to have the room.

RD800 AWD was built and tested in both Canadian and American logging industries in a tractor multiple trailer application.

The Cat in my CL753 is a nice squeeze. No R6 series is going to take a kitty without some serious modification and lube.

This is possibly a Canadian road rules question I'm not sure if same rules as U.S. I have a guy interested in my 2000 CH but he doesn't want it if he has to install elog. He would be crossing border to U.S.   The truck was built in January 2000 I'm trying to decifer rules but I'm not a lawyer so I'm confused on the issue. So far here's what I've found hopefully someone can help

he would need an ELD. If its not a 1999 year engine on the serial plate, they will just give you a hard time. 

Same goes for up here next year.

On Facebook at the moment there is a  B model that has been done up 

Has classy looking seats with dogs embossed on the back rest

 

Anybody know what these would have come out of ?

 

Paul 

Those seats were available from Mack in the 2000s. They were available for Granite CV interiors. I had one as a driver seat in my R model years ago. Bostrom mid backs tan vinyl.
