Popular Post kscarbel2 Posted March 30, 2015 Popular Post Share Posted March 30, 2015 Thank you so much for posting. Mr. May was a living legend. Though the Mack family has lost one of its brightest sons, few gentleman had a more rewarding life.Under Walter May's stewardship were some of Mack's brightest and proudest days. We are so fortunate he was not one of the engineers on the plane in '69 (http://www.bigmacktrucks.com/index.php?/topic/31112-bulldog-airlines/?hl=%2Bbulldog+%2Bairlines) when so much Mack talent was abruptly and prematurely taken from us. 4 Quote Link to comment Share on other sites More sharing options...

Gmerrill0516 Posted March 30, 2015 Share Posted March 30, 2015 Would have been great to visit with him and hear his stories. I'm sure it would have been fascinating stuff to hear. Think about what he must have been a part of. I guess in some way that is why what we do is not just fun but a way to preserve the past. I wish him many happy miles in eternity.Greg 1 Quote Link to comment Share on other sites More sharing options...

Popular Post kscarbel2 Posted March 31, 2015 Popular Post Share Posted March 31, 2015 Yesterday, I contacted no less than five Mack distributor principles and not one had been notified by Volvo of Walter May’s passing. I am far beyond offended.........my friends, I am angry today.In the days of Mack Trucks, when a member of the Mack family was injured, severely ill or had passed, World Headquarters would get the word out within 24 hours, to the factory branches, privately held distributors, Vehicle Product Development & Test Center, plants and Mack PDCs (parts distribution centers). Though having purchased Mack trucks, Volvo clearly doesn’t understand the values of the Mack family it acquired. By American and Mack standards, Volvo is showing an immense lack of respect.(With my knowledge of Scania, I can assure all that Volvo’s insult is not indicative of Swedish culture in general) Had it not been for Walter May and his team of America’s best heavy truck engineers (including Win Pelizzoni*), Volvo would not be profiting from the Mack brand today. Volvo only cares about the money, Mack is merely a brand........a nameplate they purchased to adorn their North American Volvo truck range. * Winton “Win” John Pelizzoni, co-inventor of the revolutionary Maxidyne/Maxitorque powertrain** that changed the truck industry around the world, passed away on March 11, 2011, like Walter May at the age of 97.http://www.legacy.com/obituaries/mcall/obituary.aspx?n=winton-john-pelizzoni&pid=149502579** http://www.bigmacktrucks.com/index.php?/topic/30184-all-eyes-are-on-the-new-maxidyne/ 7 Quote Link to comment Share on other sites More sharing options...

Popular Post 1958 F.W.D. Posted April 1, 2015 Popular Post Share Posted April 1, 2015 If any of you know who Jim Winsor is, he and my father and myself are close friends. Jim resides in the Philadelphia area and we get together with Robert Gabrick at least 2-3x a year and have lunch or dinner. Jim has a PLETHORA of Walter May stories. Greatest one is about the development of the first generation Maxidyne engine and Mack's "CONSTANT TORQUE." I don't have time to type it out right now, maybe this weekend. It is a story worth sharing. 5 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment Share on other sites More sharing options...

Popular Post kscarbel2 Posted April 1, 2015 Popular Post Share Posted April 1, 2015 Condolences (http://www.legacy.com/guestbooks/mcall/walter-m-may-condolences/174515678?&eid=sp_gbupdate)To the May Family,It is with regret we learn of Mr. May's passing. He was one of our greatest influences here at Mack as I look back on my 37 year career. He was a mentor to all of us in Mack Engineering.I remember him always correcting me when I called him Mr. May, saying "my name is Walter".May you his family be consoled that he is now in Good Hands and he will still wear the "Mack Badge of Honor" to those of us who worked for him.

Popular Post 1958 F.W.D. Posted April 1, 2015 Popular Post Share Posted April 1, 2015 I never met Mr. May, but since I live close by, if I can work it out with my schedule, I am going to try to pay my respects. **EDIT: Due to my work schedule and already having had pre-scheduled appointments, I was unable to get to the services.I will try to type out a narrative of the story of Walter May taking Jim Winsor for a ride in the R-Model with the first prototype Maxidyne (and the story of how "Constant Torque" came to see the light of day) if I get a chance this weekend. 4 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment Share on other sites More sharing options...

theakerstwo Posted April 3, 2015 Share Posted April 3, 2015 Maybe one year after the maxidyne was created cummins tried to build a engine that would used a 5 speed.It was a NHT 270 cut back to 240 at 2100 but with a add on torque tailoring device to the top of the fuel pump it would keed its fuel pressure up there at 1200.But it was a flop.

Lmackattack Posted April 3, 2015 Share Posted April 3, 2015 I always laugh when people would say that cats and cummins have a flat torque curve just like a Mack. They think low rpm is 1300rpmNever have found a diesel besides a Maxidyne that could pull good with a 5 speed Quote Link to comment Share on other sites More sharing options...
57 bcr Posted April 3, 2015 Share Posted April 3, 2015 The Power Torque 270. I can just here the brand X salesman saying,"It's just as good as a Maxidyne".......................................NOT! I heard the wet liners couldn't take the lugging. Go figure,Cummins seemed to have that problem a lot years ago. Brockway's "Huskidrive" used that same motor using a 5 speed and 2 speed rear end. Sounded like a good idea,You started off shifting the 5 speed with the air flipper(dash mounted) in the "Power" mode,then when you needed that extra gear for speed,you flipped the valve into "Cruise" (high in the 2 speed). Anyone had any experiences with the "Huskidrive"? Al Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!

I knew Jim from TMC (Technology and Maintenance Council).No, he is not doing too well (at the moment) He has ups and downs but this is a little more serious. I called him to see if he knew Mr May had passed and spoke with his wife at length. Out of respect for his privacy I will reserve further comment. 1 Quote TWO STROKES ARE FOR GARDEN TOOLS Link to comment Share on other sites More sharing options...

Anyone had any experiences with the "Huskidrive"? AlNo experience with Huskidrive but as I recall, the dash mounted flipper was to discourage guys from thinking they were driving a "five and two" and would end up splitting gears if the selector was located on the stick. As for the PT-270, we were a big White customer and a bought a lot of 4564's- all NH 250's. Well we wrecked one and bought a 4564 with a PT-270. I think White had built it to our specs/color hoping they would get a shot. Had a RR, RT-906. 906! 3 holes then pull the button and grab the other three! Never saw another one.Agree- Mr May and Mr Pelizonni truly invented a better mousetrap! Now 40 years later I recognize what an advance it was. 1 Quote Link to comment Share on other sites More sharing options...
