Freightrain Posted October 18, 2017 Share Posted October 18, 2017 As most know, my Triplex is whipped. It still gets me there and back but it is rough, noisy, rattling, etc. With all the other upgrades I've done to the truck I really like to find something else to put behind the 237. No, I don't want just a 5 spd. While at Gerharts I was admiring the Yoos brothers R700 and while the hood was up I noticed what appeared to be a single disc clutch bellhousing(looked short like mine)? It has a 325 hp V8 and I think a 12 spd(was a twin countershaft box). Did I see right? It got me thinking if something like that would be a nice upgrade? Or hens teeth? Expensive to fix/rebuild? My buddy keeps telling me to just throw a 13 spd in it. I told him it is not that easy, he's not familiar with Mack stuff. I don't really want to get into major fab work(clutch linkage, pedal, etc). I can do it, but if there is something simpler? Like all my other upgrades, I spent lots of time looking, searching, investigating til I have all my ducks in a row and know it would all work. Just looking for opinions, options, thoughts on the matter. When I was driving Dave's B61SX dump at Gerharts the quad box was tight as a drum. Yes, he rebuilt it. I was thoroughly impressed with it and had trouble shifting the compound because it was so tight(unlike mine). I wouldn't mind if my Triplex was rebuilt but having that done and the cost? He luckily found everything he needed, but there is one big bearing that he didn't replace due to the insane price(thousands of dollars). Quote Larry 1959 B61 Liv'n Large......................
