pull cab for repairs

Is it necessary to pull the cab for repairs like my 6.0 or have they improved the layout of the new 6.7?

Thanks

It is my understanding that you do not have to remove the cab for any repairs.

I'm told that one of the few things thay can work on with out lifting the cab off over the 6.0 is the turbo because it sits on top now. Other then that and mabye a few other little things, it is my understanding that a cab removel is still needed for most engine work. If you've look in and under the hood of the 6.7 there is still not much accessible. I had the 6.0 and now the 6.7 and I can tell you they both look like you needed a shoe horn to get them in.

The 6.7L was designed specifically so that all major bolt-on engine components could be serviced without removing or lifting the cab.

What's deceptive with the 6.7L is that from an initial look, yes, the underhood packaging is quite overwhelming. However, once you remove the upper intake, the whole top of the engine opens up. It's quite amazing, so if your bored one day and have a few minutes...


Design for service was a priority when the 6.7L engine design was still a blank sheet of paper. Moving the fuel injectors outside the rocker covers, relocating the high pressure fuel pump to the front of the engine, eliminating the 3 bolt flanges at the turbo up-pipes in favor of an accessible marmon type flange/clamp design were incorporated to improve serviceability. The location of the EGR cooler assembly on the RH valve cover allows for it to be removed and on the bench in approx. 20 minutes if needed.

There are many other subtle details like thermostat access, engine sensor locations, the quarter turn (120 degree) oil drain plug or the label on the oil cooler to let you guys know that there's an internal fastener before someone tries to pry the cooler loose once the external fasteners are removed. These design aspects were incorporated to provide a highly serviceable engine package.

The only repair that cab removal is still the primary method (but not the only) is for a complete engine rebuild with either a long block or short block. The reason being that you can't lift the engine high enough for the cast upper oil pan assembly to clear the #1 cross member before the turbo hits the cowl.

However, there are situations where the cab is unable to be removed for major engine service. These situations typically arise with major conversions such as lift trucks or other instances where either a box, camper, etc. have been added that overhangs the production cab. In these situations the engine CAN be service without removing the cab but requires a little more service time as you must remove the upper oil pan first.

It's probably helpful to know that you can actually remove the upper oil pan without removing the engine mounts. This is quite nice as you need no upper engine support while working with the truck on a hoist.

"upper oil pan" - is that a diesel term or a 6.7L term? I'm feeling ignorant =\

The 6.7 has a two piece oil pan . th eupper is a structual part of the bell housing mount. The lower is a composite piece. Right Paul

Thanks. If I decide on a new Powerstroke I sure don't want one that requires cab removal. The average guy like me doesn't have the equipment to do it.
I think I am spoiled. On both of my John Deere tractors, the cab is on a hinge. You can tilt it over to gain access to the transmission and rear end. It tilts over partially without taking hardly anything loose. If you need to tilt it farther then you disconnect the hydraulic and throttle controls and linkages. John Deere has some good engineers- that's why I buy their stuff.
Back in the 90's you had to take a hoist and completely lift the cab off.

one has to think for the $ of the engine alone,it shouldn't require any major repairs until several hundred thousand miles,making it a non issue lol.

People are still just gun shy from the 6.0! By the way, there is no reason to pull the cab to remove the turbo on a 6.0. I'm far from being a Ford Tech and 9 times out of 10 I can pull a 6.0 turbo in about 10 minutes flat unless the bolts are seized up on it. The only thing on a 6.0 that really requires cab removal is head gaskets. Even they can be done in-frame, but it's much easier with the cab off.

I was at the dealership yesterday trying to convince them (unsuccessfully) that they should reset my TPMS and there was a superduty with the cab lifted.

I must say it gave me a queasy feeling. Not sure if it was a 6.0 or 6.4 since I was too busy telling the pecker head to just hook up his gadget to my truck and let's find the place and set that thing. He said he couldn't because dude with lifted cab was paying $130/hr to get his trucked worked on. From the look of it it, I don't think this was warranty work.

Anyway, here's hoping none of us have to have cab lifted. Jeeze, it's like open heart surgery or something.

Actually lifting the cab is a very simple procedure for anybody that has done it before. A crewcab can be up in the air in 1 to 1.5 hrs depending on the tech. People freak out about it, but it makes major work on the motor so much easier. I've seen techs that pull the engine to do head gaskets before. I'll take the cab any day of the week over doing that.

6.7 turbo gasket

Good morning y’all. I recently purchased a 2011 f250 with the 6.7 turbo diesel. I had it 6 days and noticed a major oil leak under the truck. Took it to the dealership and they informed me it’s the “turbo gasket” that is leaking. And said they would have to pull the cab to replace the gasket. And to also inspect the turbo to make sure it isn’t cracked. They hit me with “it is gonna be around $1,100 to change the gasket because we have to pull the cab”. From the research I have done it looks as though they shouldn’t need to pull the cab to replace the gasket. Can anyone shed any onsite or light on this for me please before I am handed a large bill for a $30 gasket.

Just noticed this thread and thought I'd add my $.02. I had a 2012 6.7 in the shop with numerous oil leaks with the turbo being one of them. For the Dealership that said the cab has to be pulled for this repair... I say run from that dealer. I had the turbo out in 1.6 hours and it was my first time on a 6.7. It's not a horrible job. I was quite impressed actually with the clearance when pulling the turbo out. Also had to replace the upper oil pan gasket. Now that is a job!

If I had to work on the 6.7L, I'd probably opt for cab removal. The trucks are high off the ground, you really can't lean into the engine bay without being on a step ladder. You might have the 1.5 hours into cab removal, but then everything is so easily removed.

A tip-forward hood and fenders would be amazing on a truck like this. I'm worried the 2018 GM 4500 / 5500 will have this feature and it will be a major service advantage and cut into Ford sales.

That said, the EGR cooler doesn't look terribly hard on a 6.7L. Turbo sits pretty far back, but with upper intake removed there would be access.
