Long time no see, from Australia, help with 6.7 Purchase please....

I sold my King Ranch F-450, love it, but need a flatbed and want to try the 6.7... Maybe in an F-550 4x4 Cab Chassis, and build a Gooseneck bed for it...

Now in Australia, it is REALLY HARD to get major cab off Service, especially out Bush... Thank you in advance for the answers to these two questions:

Questions:
1) Can you Service the Turbo, or do a head gasket replacement on the 6.7 in cab??? I mean anyone could do it with a manual and help, in cab, but cab off would scare a lot of truck mechanics out of trying... By the time I add air brakes over, needed by law here over 4500 kg trailer, by the time I add that there is too much air lines and extra wiring and controls to disconnect as well. So can the basic (could happen) turbo seal or bearing or head gasket jobs be done without going cab off?? I know harder to do.. But cab off hoist in the Outback would be tough...

and 2) How has the 6.7 panned out for heavy work towing over 15,000 lbs? An improvement over the 6.4 in general opinions? Not that I had any problems with my 6.4, I loved it and half regret selling it right now. It is either a full auto big truck like an MAN, or go this F-550 way and there is a 2011 F-550 4x4 Cab Chassis available, new...

Thank you for your help... Cowboy in Australia, out on the "Last Frontier".....

Sorry if it's off topic. But how did your 6.4 hold up, how many miles and did you have any problems. I know you had a lot of great things to say about the 6.4 and look toward to your feedback.
Thanks
Dave

Well, from my study, the 6.4 is just an awesome engine, just over 40,000 on it no problems... By my study is as an Engineer, following how 200 others are going.... I even have the Ford Program, VDS, and VCM to plug in.... I am an Enthusiast..

I think from my study of over 200 trucks here, and talking with the Importer that backs them up, the problems relating to the 6.4 are mostly caused by water in the fuel... Due to the immense distances here, remote station fuel depots, fuel in cans and drums, because of these conditions we in Australia are more in tune with meticulously keeping water out of our diesel and checking for it...

I think most of the problems are water related, overcoming the Ford dewatering system and then the injection systems blows, even the tips off the injectors can MUNCH the engine... I sold the King Ranch because I need a heavier duty flatbed and did not want to ruin the looks of the 09 F-450 King Ranch... I may be moving up to a MAN truck, Crew Cab 4x4, 12 speed auto. Considering an F-550, because I am interested in the new 6.7 for my R&D for Bushtracker Owners travelling in the Outback.. But 60/40 in favour of the MAN truck...

Anyway, my 6.4 was flawless, and to tell you the truth I have not heard of one going down in 2 years here. In fact I think they still have the back up motor in stock in Melbourne (by law to carry as an Importer)... My opinion is that most of the American Drivers seem to take good fuel for granted, where we are very careful. I think this accounts for a good portion of 6.4 failures. International/Navistar is still using the 6.4 in trucks and buses, feed it clean fuel and I think it is a great engine..!!

Cheers from Australia, Cowboy

I'm not remote but live in the middle of nowhere...................You couldn't give me another Ford diesel. It's the only diesel truck that I've owned that gave me problems on the road in the bush on a winter hunting trip. You should be finding a diesel of some sort with mechanical injection and reliability to the CORE! Are mechanical diesels available in Australia? I ran a boat for a few years that had MAN diesels and they were bulletproof. Good luck to you with whatever you end up with.

Hello Olypopper,

Thank you for the response... Only help I got in two weeks... never mind..

Funny you should say that about the MAN, but after weeks of research and a year of MAN truck research, I bought a MAN TGM 4X4, a short wheelbase one.... It is only about two foot longer than my F-450 CC DRW King Ranch.

Ordered with passenger ISRI air seat as well, diff locks front and rear, a real beast of a thing and I can tow 20 ton...

First time in a decade, I am now Fordless....

Hey Cowboy,

Sorry to hear that you are fordless but this is what I've heard on the 6.7's:

The cab & chassis 6.7 super duty's here in the US are detuned by about 50ish horsepower vs the regular trucks. But it seems like you would be able to do everything cab on & I think ford designed these new engines to be that way,

The only real problem I've heard the cab & chassis 6.7 having is that the turbo doesn't hold up too well. But not sure if that was just a early run issue that has been resolved or not. Other than that, they are pretty rock solid.

Hope this info helps!!

I finally got my 550 back from the dealer after a week. They were having computer issues so they couldn't do the update for the nox sensor. Truck still has bad lag even after the new turbo got installed last month. It has also developed a bad vibration from about 55mph-80mph. Dealer said the truck is overloaded and is chopping the tires. I call Bull. My other trucks don't do it. It's a 19500 GvWR truck that's still about 2500 lbs away from that.
