I remember once seeing an early DM It didn't have any dash pattern. It had a 673 and what as best I could tell was a quadraplex. I remember the compound was backwards if you tried to drive it ???

Onyx610 Posted March 30, 2022 Author Share Posted March 30, 2022 Once you get to learn them they arnt to bad and easy to fix. Usually “common issues” only problem with them is you damn near have to take the cab off to do anything. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69424-shop-talk/page/14/#findComment-493846 Share on other sites More sharing options...

mechohaulic Posted March 30, 2022 Share Posted March 30, 2022 I do recall dash shift patterns that had two spots backwards. never paid that much attention as to why. i wasn't in to numbers that much(TRQ/TRD etc ) then . main motto was ;; if it's broke fix it . once had a customer that missed a shift on a hill ::mack F-600 with duplex. shattered the back half. he "acquired "another 10 speed from a competitor down the road. using a backhoe i pulled the trans, swapped parts to make a good one . installed alone;; any idea of trips from backhoe to truck lining up the trans . point is there was a big difference in front/ rear half ratio afterwards. he complained , i said then don't steal the next one buy the right parts!

mowerman Posted March 30, 2022 Share Posted March 30, 2022 You know to tell you the truth I haven’t driven the truck on the road for 27 years and now I’m not even sure about what transmission I got but it’s junk slips out of fifth main box and I’m putting the quad box in it that I bought and yes it’s a turbo end673t.

Joey Mack Posted March 30, 2022 Share Posted March 30, 2022 nice,,, I actually put a 'cammed up' 400 in it a few years ago.. I could put on one hell of a show,,,, but.... I couldnt 'work him' like i used too.. I would go to get supplies and I either had to drive through the parking lot at 3000 rpm in the granny gear, or work the clutch in 1st,,,,,, just to find a parking spot... what the hell was I thinking??? i tell you what,,, I was the 'Sh!t' in 2nd gear on any city street, just sayin.... so I pulled it and put the worn out 350 back in.. I need to re-build the 400 with a towing cam, and mabey even put the rebuilt 2bbl back on it... jojo 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69424-shop-talk/page/14/#findComment-493868 Share on other sites More sharing options...
tjc transport Posted March 30, 2022 Share Posted March 30, 2022 we picked up a 78 C30 at auction around 1990 with "fresh rebuilt 350 and new clutch" on the windshield. under it was bad vibration in engine. paid $50 because no one else wanted it. pulled the engine, and sold the rest for $250. pulled the flywheel off after determining it was a 400 and put a 400 flexplate on it, bolted a turbo 350 to it, and stuffed it into an old woods crasher rig we had built back in winter of 74 on the farm. and proceeded to get into all kinds of trouble over the next few years. the woods crasher was a 62 ford wagon frame with body removed, frame shortened 5 foot, and welded back together with full roll cage..... and welded spiders in the 9 inch. 1 1 Quote when you are up to your armpits in alligators, it is hard to remember you only came in to drain the swamp..
