kscarbel2 Posted July 31, 2017 Share Posted July 31, 2017 The tandem United States Post Office (USPS) MCs and MRs had Rockwell drive axles, as I recall SQ100s with Reyco 101A or 102W four-spring suspensions.

Lmackattack Posted July 31, 2017 Share Posted July 31, 2017 About 10 years ago they had a mass sell off of them. most were 250 or 300HP with automatics... a few guys picked them up and turned them into dump trucks. first time I had ever seen a MR pulling a dump box Quote Link to comment https://www.bigmacktrucks.com/topic/50618-still-looking-for-usps-mr-tractor/#findComment-376235 Share on other sites More sharing options...
TeamsterGrrrl Posted July 31, 2017 Share Posted July 31, 2017 The biggest fleet of USPS MRs were the 96s, 300 HP with an Allison 740. The purchases after that were increasingly CH and later CX conventionals, culminating in a big '06 purchase that is still in service. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50618-still-looking-for-usps-mr-tractor/#findComment-376249 Share on other sites More sharing options...

I was thinking more of how the driver was going to feel after a day of off roading in one of those things. they seam to be a rough rider even on the street.

The R-model based MC was reasonably comfortable. But with MC sales never meeting expectations, we discontinued it to focus on the strong selling vocational MR. But the USPS wanted us to continue bidding a low-cab-forward tractor, so we down-spec'd the MR to create a tractor. With a heavier DM-like deep frame, It had a rougher ride. As I recall, Mack President Henry Nave promoted the idea for the MC/MR, based on his positive impression of Crane Carrier's similar Centurion. The Centurion was launched in 1974, the MC/MR in 1978. And I always believed there was some communication between Nave and Curcio, the latter who briefly left Mack (than heading the Canadian Hayes subsidiary) to work for Crane Carrier from July 1973 to March 1976. And of course Henry Nave had previously been President and Chairman of White where the low-cab-forward "1500 Compact" and "6000 Xpeditor" had been strong products. Though Crane Carrier's Centurion never achieved high volume sales, it was the catalyst for a new generation of purpose-design refuse trucks. Speaking on this subject makes me recall the MB series 6x4 tractors we sold to the U.S. Navy for warehouse to commissary delivery. People tend to forget the MB, but it was an extremely crucial product for Mack Trucks within our line-up during the 1960s and 1970s, and we sold thousands. I never met an Overnite or APA driver who complained, and their accountants loved them. . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50618-still-looking-for-usps-mr-tractor/#findComment-376337 Share on other sites More sharing options...
bulldogboy Posted August 3, 2017 Share Posted August 3, 2017 The Mack "MB" fire truck was the way many small volunteer fire departments entered the "custom" fire chassis market. Until then most small departments used Ford, Chevrolet, or IHC chassis. The "MB" gave them "big city" features such as jump seats, dual ignitions, keyless starting, and other NFPA recommended items. Later, these departments could move on to "CF"s, ALFs, Duplex, Spartan, etc. My department was all "CF" but we had one "MB" (budget cuts!!) and two neighboring departments purchased their first custom engines, Mack "MB"s. bulldogboy 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50618-still-looking-for-usps-mr-tractor/#findComment-376561 Share on other sites More sharing options...
