I pleaded with them to pay up for the indestructible Maxidyne/Maxitorque drivetrain. They had Internationals with that small diesel and Fullers.......one couldn't convince them that Mack had an altogether different and game-changing powertrain. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-567433 Share on other sites More sharing options...
Geoff Weeks Posted January 23 Share Posted January 23 It is more easy to sell an O/O on something new and different than a fleet. They want all the same, no changes. A fleet full of half one way and half another, along with slip-seating is a recipe for an unhappy customer. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-567437 Share on other sites More sharing options...

Maxidynes were hardly new in 1981, and what they were replacing was a mismatched bunch of everything. It was George Harms Construction and they went from pretty much nothing. to a whole yard full of brand new equipment when they Got the contract for the Black Bridge, and a big contract to replace power structures along the railroad. He seriously went from a guy in a pickup and a flannel shirt, to a guy with a private helicopter in the space of a couple years 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-567493 Share on other sites More sharing options...
Popular Post Freightrain Posted January 31 Author Popular Post Share Posted January 31 Well, I got it home. ETAZ673, TRL107, 2 PTOs, starter, I got the fuel filter off the frame and power steering/reservoir. I am going to take it to work tomorrow and get transmission removed so I can bring them home separately so I can unload them. I don't have anything big enough as one piece! I will be trying to start it at some point when the weather warms up a bit. Odometer said 31k miles but being a pump truck it has likely many hours on it. Looks like it has newer turbo and air compressor. I doubt it will get in the truck this spring? I may do a quick rebuild with it sitting in the garage. Will see how it runs. 5 3 1 Quote Larry 1959 B61 Liv'n Large......................

Popular Post Geoff Weeks Posted February 1 Popular Post Share Posted February 1 Just my 2 cents, if the ratios work for you, I keep the triplex that you just went through. You know the condition, and you aren't moving heavy loads where you would be pulling hard in the lowest gears. I've never thought twice about putting 1.5 times or greater the torque rating though the USED transmissions I have had. Yours has new bearing and bushings, you know the condition of the dog clutches. "stronger" I wouldn't consider it worth the time, better match to the engine and rear, might be worth it, depending on how bad a match the triplex is. 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568311 Share on other sites More sharing options...
mowerman Posted February 1 Share Posted February 1 I was also thinking the same thing after all that work unless you can find a buyer for it that will pay you what you got into it. You’re kind of stuck between a rock and a hard place. I’ve never heard of anybody burning out a transmission, but I got that from a Mack truck salesman years and years ago he said they really weren’t made to take a lot of torque. Maybe just run it a while and see how she performs kind of takes all the charm and romance out of it if you put in something with a one stick good luck whatever you decide Larry. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568313 Share on other sites More sharing options...

"stronger" I wouldn't consider it worth the time, better match to the engine and rear, might be worth it, depending on how bad a match the triplex is. Depending on who you talk to is if you need 5 or 10 spds for this motor. The triplex is versatile enough I am sure it would work just fine ratio wise. I know I'm not heavy but torque is torque and I don't want to have to drive it like I have an egg under my foot. I can't use just the current 5 spd because I need OD. Or I would have to change rearend. My second thought is install the 5 spd, replace my little 6041 aux with a 1241 that would accept the torque. That would get me splits, a deep under, and an OD. The 6041 needs to be gone anyway if I install this engine. That tiny box would not like this kind of power. Could it? Maybe, but again I am not willing to accept the risk of failure someday(at the worst opportune time). I will spend money to build it right the first time. Crane at work getting engine off trailer. Removing 5 spd so I could bring it home now. Weight of transmission. 750#. Surprised me, thought it would be heavier. That includes two PTOs. I have the transmission at home. Will now get friends smaller trailer and bring engine home. I'm going to weigh the engine when I pick it up. I forgot to when I moved it, and wasn't going to resling it right then. 1 2 1 Quote Larry 1959 B61 Liv'n Large......................

Popular Post Mark T Posted February 1 Popular Post Share Posted February 1 One of the problems with the smaller Mack Triplex or Quadraplex with biger engine was keeping tho oil cool. Once they spent more time in overdrive, oil temp. got to being an issue. If you have a Triplex and a four way behind it ??? you're double overdrive. That bigger engine, likely you'll need a faster axle, and skip the four way. Unless I'm reading wrong 4 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568318 Share on other sites More sharing options...
Geoff Weeks Posted February 1 Share Posted February 1 Shock load can kill anything. If you are not an idiot, and I know you're not, then you aren't going to twist a shaft with a little more engine. Your money, your choice, but I wouldn't loose a minute of thought about using that engine with that transmission. One place I worked, one driver broke the shift handle off the 1/2" rod, now he could break an anvil with a rubber hammer. Your not pulling hard 10 or more hours a day, I wouldn't worry too much, You can run SAE 50 that handles heat better than GL. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568319 Share on other sites More sharing options...

Geoff Weeks Posted February 1 Share Posted February 1 And how many souped up 3406, Big Cams and KT19's were running around pulling freight when the biggest transmissions were 1200 ft/Lbs? Rear axles that were geared fast so the high power engines could reach triple digits and still held together with all that torque? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568330 Share on other sites More sharing options...
Joseph Cummings Posted February 1 Share Posted February 1 That engine was never coupled to a 5 speed from Mack. It's not a Maxidyne high torque rise engine. It was always coupled to something 9 or more speeds. If your triplex is a 2 inch input shaft and a dual disk clutch I wouldn't worry about it 2 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568331 Share on other sites More sharing options...
Joseph Cummings Posted February 1 Share Posted February 1 Turn that aux transmission around and you had an easy triple digit truck if you had the power. Just don't let it idle with the main in gear and the aux in neutral.

If he did put in Lo-lo with it turned around I wouldn't bet on any part of the driveline staying together. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568338 Share on other sites More sharing options...

davehummell Posted February 2 Share Posted February 2 Back in the seventy's I used to take care of a fleet of R's and F models 237 and 300's all with the 5 speeds I can't remember any of the truck drivers tearing up the trans or the rears.. Engines I did one a month and you had to pay attention when running the valves some were dynatards we ran about 27 or 29 Macks and some ran the coast and Canida runs. My old Autocar had a twin stick 4x4 and 262 Cummins. I ran flatbeds, equipment trailers, vans with the 5 speeds not my favorite trans I like more gears. I had the chance to give the 3408 in a Pete a tryout I liked that engine my all-time favorite was the 1693 I could really get some power out of that engine on the dyno. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568345 Share on other sites More sharing options...
mowerman Posted February 2 Share Posted February 2 Ha ha I ran a five speed. I hated that thing 237 Maxine then I traded up to a 350 Thermadyne and a nine speed big difference. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75053-latest-find/page/2/#findComment-568347 Share on other sites More sharing options...
