Re: Mack M75SX
That's a nice 1 ton dually you have there, Steve. I like the direction your Mack is headed too. I have to echo what the others said. Keep the axles. They are really nice. I'd suggest you just find yourself one big and brawny gearmotor to use as the transmission. We could calculate a good ratio for you, based on tire size, motor selection, and the voltage you want to run. As long as we know the motor's RPM per volt, or Kv rating, and an idea of how fast you want this thing to go.

Re: Mack M75SX
I'll have bb's all over the floor unlees I glue the bead . As soon as I turn loaded I roll the 1 tire right of . they look like they have 20psi of air in a tire that should have 100psi of air I got another plan , expasion joint for concrete slabs .
isn't that the name of the game Quote:

Re: Mack M75SX
couple weeks ago I tore the rears apart and re shimed them . I had to press a stel stop in the axle bore do to a change in direction since I machined the axle cassings I'm useing HPI savage ring and pinion assembly that has the shaft cups for the pin and ball shafts for independant suspension . well I machined the ID bore to keep them on not thinking the OD of the cups being close to the OD of the bearing . well I made my own axle shafts and eliminated the cups . So when I shimed up the diff and ran it a little the copper shims started working into the bore Now she'll pull like H@!! you can't put enough on it to stop it . Tonight I took a little time and mounted the oil tank and pump whille my wife helped pack up some orders to go in the mail tomorrow I also started on the cylinders a couple weeks ago . I did fix the front tire issue just added the foams from the distorted tires I have
thanks for lookin

Re: Mack M75SX
Steve, Just think, a week today there's going to be a bunch of people layed off at the North Pole. Might be cheap labour to help you catch up with your projects.

Works nice Steve! It sure has some speed behind it too!
Better make sure you tighten the lug nuts on that left rear wheel!
