New T-880 MX-13 Allison

They arrived. MX-13 455/1650 Allison 4500RDS Meritor RT46-160 4.10 Ratio.

 

What is heaviest gross they will run at?

 

Depends on state! 73280 in Indiana, 80,000 in Kentucky, around 63000 in Ohio but need to put tape measure on it.

 

Might wanna shorten the steering stops on those bad boys...lol...from the factory there is ussually plenty of room to open them up a bit. Pretty they are. Not much steel up here, any specific reason you didn't go aluminum other than the cost?

 

Sure it can. It involves adjusting the steering stops in even on each side. I Always make it the same number of steering wheel turns to match left and right. You need to be careful and check tire clearance during full turn so nothing rubs outer diameter of the tires on the inside edge. Once manual adjust is done and check for clearance, reset the poppets in the steering gear so it will have power assist to the new stop position. Going open is easy. It's going tighter that becomes a bit more involved.

 

Lowest rpm possible for 150° coolant temp?? That is the stupidest thing I've ever heard. I don't care what engine maker told me that. I'd laugh in their face.
They make money when engines break, or blow up.

 

With work we do with quads we go with steel beds. These are AR-400 steel. Have a couple with Hardox. AR-400 or 450 seems to hold up about the same. Six axles dumps we run aluminium beds. Adjusted many steering stop. Two in picture have 315 steer tires and we probably switch to 425 so sure stops will be adjusted then. Have had to add adjustment screws in TRW boxes in past to reset poppets.
