Being a direct drive it will hurt your top speed. The stock 3053a trans has a .79 overdrive in 5th gear.

How much are those axle gearsets running with the 4.88's? quckfarms he has a CAT 7155 trans in his m923 instead of the Allison. 1st gear is even lower than the Allison's reverse gear.

The 855 series engines in commercial rigs regularly go 700k-1 mil miles, or 15k hours in stationary units. That's the longevity I'm talking about and want yours to reach. They don't go over 2100rpm for long though in commercial use. Can the 855 series spin over 2100rpm? Yep, but they are known...

Big Cams don't like regularly sustained over 2100rpm either (if wanting a long life out of it). Realistically no engine of that size likes being over 2000-2100rpm for long. The smaller engines like the 8.3L will last longer at those rpm's. Supposedly the tcase from the m916-m920 has other...

If it's setup the same as my droid then you will see a little envelope near the top of the screen in tapatalk. Tap on that and it will show your messages

Check with any local injection pump rebuild shops, might get lucky. If not there then Cummins can get it.

855 series Cummins and the C15/3406 CAT's won't fit. When I had a m51a2 parked next to my m816 I checked that out (could get my hands on another NHC250 for cheap at the time). The pulley's from the NHC250 would be in the radiator on the m51a2. There's a reason the manufacturer spent the modern...

I run 1/2 gallon of coolant in the tires for balance, has worked great. Centramatic's work fine on the commercial trucks I've worked on. The older 5 tons had the hydraulic brakes so that's probably what they are thinking of. Best option, take the truck down to one of their distributors and...

I know on the older wreckers 395's can touch the bed under full articulation. m936 and older models (can't remember if it was the a1 or a2 when the bed was modified for the 14"s).

Compressor wheel is already chewed up, I wouldn't use it anymore. A fuel injector issue can go away on it's own sometimes.

About 1540rpm at 60mph with that setup. https://www.ringpinion.com/calculators/Calc_RPM.aspx Not worth the cost to swap to an auto trans. Could sell the truck and go to a m939 series for cheaper than that. She can learn to drive a stick to. Friend of mine got a crash course one night being the...

The 8.3 relies heavily on the turbo to make it's power. Without the turbo working the power to weight ratio is horrible, like a little Toyota pickup with the 22re 4cyl and 5k pounds of trailer behind it will be a hotrod in comparison. Probably not a engine rebuild needed. Knocking noises from...

That depends on which MRAP family you are talking about. Ours had C18's with full time 4x6, part time 6x6, and air lockers in both rear axles.

According to others experience on the T1138 into a m809 series it will put you at about 1800rpm at 60mph if still on the 11x20"s. Not quite a direct bolt in but not a complex swap.

Plasma, much faster

Got slowed down a bit but alot of the frame slicing happened today.

gauges get swapped often in these trucks, your tach has been swapped.

Haha well if you're going to copy what I did then need to either part out the truck or turn it into a trailer..... hahahaha. Mine is becoming one of the beds for the m816 and trailer. I agree with 98G. So long as there is enough traction a deuce or even a 1 ton pickup could push it onto a...

Another truck with a towbar could push it onto a trailer just fine. As far as engine swaps go the NHC250 and other similar sized engines won't swap into that truck, the engine bay is too small. The 8.3L Cummins, International DT466/DT530 (couple others that use the same sized block), CAT C7, etc...

Didn't do any actual work to the trailer lately but did some brainstorming. Mostly for spare tire mount, mud flaps, and storage boxes. Part of the plan for this trailer is to have multiple beds (same with the wrecker plans). So started laying out plans along the chassis for tool boxes to carry...
