Maddog13407 Posted February 24, 2012 Share Posted February 24, 2012 anyone have any pictures of what the levers looks like originally in a B model? recently replaced the duplex in my B613 with a triplex, used the same 5 speed stick and the two sticks were hitting and crossing each other. i heated them up and bent them apart but dont like the looks of them. have seen some sticks bent from the factory low and some auxillary levers bent high? would just like a pic of some original ones that have not been heated up and bent 100 different directions in the past 50 years.thanks, Matt Quote Link to comment https://www.bigmacktrucks.com/topic/23441-triplex-or-quadbox-shifting-lever-pictures/ Share on other sites More sharing options...
Freightrain Posted February 24, 2012 Share Posted February 24, 2012 Grrr, I just bent my main box to make some room for the aux shifter I put in. Other then that it "WAS" original. You can see the warm marks where I made it straight instead of dog legged. The aux is original. Here is a bottom shot of what the main used to look like: Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted February 25, 2012 Author Share Posted February 25, 2012 thanks for the pics Larry. i have seen them bent at the floor and to the left and right and have also seen them bent to the left and right about half way up the stick. same with aluminum components in a B model. does not seem to be an rhyme or reason, every truck seems to be different. took my truck for a ride sunday since we seem to have spring type weather here in upstate NY, cruises alone really well and is more in the power band of the 711 with the triplex behind it rather than a duplex. with 4.00 gears it will do about 60 at 1300 r's. should be good for about 80 doesn the New York Stat thruway haha. dont even have the use overdrive/high split if you dont wanna and the triplex i got ahold of seems to be the quietest Mack tanny ive ever hear. dont think i ever drove one that didnt whine or whimper in low range haha. this one is dead silent.

Maddog13407 Posted February 25, 2012 Author Share Posted February 25, 2012 thanks for the pics guys. i love the straight out of the floor look but they kept crossing each other. guess thats what you get for piecing different trucks together ha. so far it has a 59 frame and cab, 60 b42 front sheet metal, 65 air cleaner,63 fuel tanks, 66 transmission, 75 engine, 1980 rear end out of an r model and front axle and spring from a B61SX . definately a two stick mutt...

Freightrain Posted February 29, 2012 Share Posted February 29, 2012 I know mine would be in trouble if it had a duplex and pulling any kind of weight. The Triplex really does a good job of keeping my 673 in the powerband. With my 4.10 gears, single OD PLUS another OD in the brownie, I'm geared for like 85 mph!!! (maybe off a cliff with a tailwind). Don't think 180 hp is going to do it with 28K lbs. Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted February 29, 2012 Author Share Posted February 29, 2012 yeah with 4.00 gears and m y duplex with 711 i was pullin a little lowboy with another b model on it this past november. could never find the right gear and was never right. honestly the 10 speed direct was never right for the 711 period. never could get it in the powerband. think someone put an overdrive gear or two in the back half of the 10 speed. it never shifted right. now with the triplex, took it for a ride the other day when the roads were bare here in Ny and could pull away and keep with traffic between stoplights. really made a difference. of course the speedometer is all screwy now. had to get a new end put on the cable to fit the triplex as it had a smaller shaft on the drivegear, now the speedometer is off about 10-15 MPH. anyone know if i can just change the small drive gear? the duplex had 14 teeth on the small drivegear and the triplex has 13. was just gonna swap but didnt know if it would mesh with the big drive on the back of the tranny?
