Maxxforce diesel engines

[Renze]

This particular engine is a Maxforce 10 at 330HP, so it’s smaller than the MAN.

The MaxxForce 10 used to be the DT570 developed on a DT466 base. The same goes with that: IH had a very reliable engine platform but their CEO with no engineering experience was hell bent on "diesel only" meaning EGR to reduce nitrous oxides where Europe adopted DEF already.

Death By Hubris? The Catastrophic Decision That Could Bankrupt A Great American Manufacturer

One of America's most storied manufacturers, $14 billion Navistar, survived the Civil War, the Depression and World War II. A stubborn decision by its CEO has jeopardized its future

Thats exactly the reason that Freighliner and Detroit Diesel are using Mercedes engines, Mack/Volvo the European Volvo engine, Paccar the European Daf engine, and only Cummins (who kept up its DEF experience due to their presence on the European market) kept as an independent American engine manufacturer...

Navistar CEO Dan Ustian riled up the EPA to hold back DEF while his own engineers knew it was physically inevitable.

I have a HT570 in my 7500 4x4. Just did a head on that one. $9,000!!! WTF!!
I figured it was just an HT570 with a DEF system and a more complicated EGR system.

Damn...that hurts :-(

Yeah, but thats why a similar Freightliner with a Cummins is $60,000-$100,000.

They are giving away the Maxforce Internationals.

I was half thinking about putting a dump bed on my Volvo semi. It’s not 6x6 but it meet the other criteria I wanted being automatic and 405 hp. I’ve not seen any other dump trucks that are comparable for less than 40-50k.

Ummmm......that would make me think a bit harder that there's a good reason for it. Not trying to be a downer but.....I'd be nervous as hell. Then again, I'm not one to gamble.

No, you are exactly right. It’s a gamble. These trucks are being sold for next to nothing as a trade-off on Maxforce engine reliability issues.
Kinda funny how you’ll see 2 trucks, nearly identical, the only difference being one is maxforce and the other is pre-maxforce and the older one sells for more $.

….just wonder if the low purchase price could be low enough to allow me to take a chance that I could “bulletproof” the thing, like guys that did it to 6L Ford Powerstrokes?

The rest of the maxforce truck is fine.

....that I could “bulletproof” the thing

So is it just the EGR that goes bad or is there more?
The only actual involvement I had with the failure end of them is like I had said previously, a friend of mine drove one that was on a unique piece of equipment and it was constantly in the shop for leaks and other failures that shut the rig down. Numerous others were always in the shop as well but I never really looked into the problems, I just heard the supervisors constantly cursing and having to revive older trucks that had been mothballed for auction to put them back into service..
Is there a bunch of things that are bad ? I know the EGR leaking was one I remember for sure.

Leaking EGR, failed DPF’s, turbo actuators, etc.
Even the replacement motors have little improvement.
They moved on to Cummins in 2016.

So if I wait a few more years, maybe I’ll be able to afford a Cummins powered version

Sounds like the whole thing is a boat anchor. I stand by my previous assessment on the last rig you were looking at. Walk away....far away.
