Tri drive?

The R model underwent several slight improvements over its 20 or so year run. What were some of the major changes to the B 61 Model. Not counting B-53, 57, 67, 70 etc.

Gleaner- Read Kskarbel2 comments on the Cruiseliner. If you have one with the squarish grill it was built in Pa and shouldn't have any of the west coast build problems

Most refreshing news for Mack North America. Now all that's needed is follow through. Lets not get our hopes to high though as Volvo still calls the shots. For starters bring back the Superliner with big power. This will replace the Pinnacle AF which struggles at best as Mack only half heartedly promotes this model. This will make Mack competitive in heavy haul, trailer dumps, logging etc.

Any guesses as to what Mack gas engine this would be and transmission.

If Australia made left hand drive trucks available would they be popular in the US and Canada. Models such as Superliner Trident and (more optioned) Titan

How does that compare to the Alco big boy

Not an R but. Saw a neat picture of an old Mack B-61 with a trailer dump for Palumbo NO. 152 on facebook.🙂 Are they still in business?

I believe this is the later rendition Cruiseliner from Allentown. supposedly built better

is that D-T a 921RB?

Always liked the smaller grill on the Acar. Can't sacrifice cooling though.

Orange and ugly. White one isn't to bad.

Make sure the salesmen knows about the 16k fronts on the CH Pinnacle. They may not be up to speed. I think you can get 20 0r 23 fronts on the Granite.

Do you haul milk when manure season is over?🙂

Double frame on a 2 axle that is rare. Looks to be in good shape

On Saturday 10-16 2021 I saw a royal bluish Mack steel nose DM 600 tractor pulling a loaded lowboy in East Hampton Ct. I was wondering if any one has any info.😗

Not sayin its a Mack but not a Winnie either

Wheels are to HD for a Winnie

Looks like a lot of used Mack's get turned into new KW's

FW for runner of the lJ. Thanks for posting.🙂

IH kB's and R's were good solid trucks.

The 673 Mack naturally aspirated and later turbo versions were great economical and reliable engines. However it was to small to compete with the 855 Cummins and its turbocharged versions in the day. Mack's first answer was the 711(never factory turboed) which had its share of problems and it was still to small to compete with Cummins and Detroit. Next Mack went with the 864 V8 but as with the 711 it failed in the market place. About this time Cat entered the scene. Mack just didn't have a big bore product to compete with Cummins Cat and Detroit. Mack lost diesel momentum until the 237/300/350 came along. These were great engines which sold well, but they were still on the small side. The E-7 mechanical was a great engine but again on the small side. By the time the E9 was perfected Mack had lost the V8 momentum. The Mack electronic emissions engines were also problem prone as were other manufacturers engines. If Mack had pursued the "Big Six" instead of the V8 or along side it, they would have been better off IMHO. The present MP-7&8 engines are Idecent engines but still can't compete in the western mountains or Canada. Volvo wants to push their product for these regions with the ISX-15. They would be better off pushing the ISX- 15 in the new Pinnacle. This would put Mack back on the same page with Paccar, Freightliner and VW (Navistar). When was the Reo V-8 first used and how long did its run last. Who else used the Reo V-8 besides White? I see they were 440 cubes and 1200 pounds.

Thanks for the enlightenment Mrs. Paul! Agree with you Mark T. Also wern't the the h-61 cherry pickers also called highliners.

Just curious as to how Mack was able to use the term liner as in Superliner, Cruiseliner and Valueliner when Freightliner already was using the designation. I guess it wasn't copy righted.🤫

I remember the Mack cab model number CA47 from Sheller Globe. I thought this cab was used on the R/U and DM models. Were the R/U and DM cabs all the same width? I think there were a couple of different cab models of the CA model number.
