I have a 2011 Ford F-550 Super Duty 6.8L V-10 with a badcamshaft. Is there a way to replace it without removing the Cab? Any help wouldbe greatly appreciated.

When my 08 engine went south, I suspected it was a bad camshaft. The Ford dealership removed the cab to do the exchange. No lasting effects on mine but they told me they had to remove my cab due to my welded on Texas front bumper.

 

How do you know it's bad?

 

Problem is, depending on how "bad" it is, it might have either spread metal throughout the engine, or took out the cam journals in the head.

What are the symptoms? Got pics?

 

Thanks for the response, there are three lobes that are completely worn flat and the rollers look like a dog chewed on them. I have an overhead crane, but its in use now, so I was hoping to get to the cams without taking the cab off. Of course my warranty ran out 23 days before this happened and Ford up here in Alaska takes forever to get anything done and charge a mint.

23 days after warranty with worn cam lobes- you might be able to push hard enough to get that covered. There's a lady on this forum that helps with oddball Warranty and service stuff like that. She works for Ford.

Someone help find her.

All that aside: I would not assume it is safe to replace the bad parts and stop there. As mentioned by Krewat, that metal is still in the engine, and very likely could have contaminated other vital bearing surfaces.

Go find that warranty girl.

 

I'll do what I can, they are pretty stingy when it comes to warranties up here

 

Ford has made it easier and quicker over the years to pull the cab. They did this because the diesels crapped the bed pretty regularly and needed the cab pulled to do major work on it. Look at some youtube videos on pulling the cab on similar year diesel trucks.

I do agree on trying to get it covered under warranty. It may have been a roller follower failure which wiped out the cam lobes, bad cam or lubrication failure. Ford has been having problems with V10s here in the later years, seems like especially in the 450 and heavier trucks. Probably due in part why they decided to go with 5w30 oil vs 5w20 in 2016. For cold Alaska temps I would be running a 0w30 synthetic oil all year round. The 0w30 makes a very noticeable difference when the temps get below 0.

 

Thanks for the reply, I've pulled the cab on several Ford trucks (that's all we run at our shop), I was just hoping there was a way to get around it due to the logistics of moving trucks around to get to the over head crane. I'll bring up the oil and see what management has to say about it.
Thanks again

If you don't want to pull the cab then you pick it from the front. You just have to remove the radiator, supports and basically everything in front the engine. Even the 6.7l can be pulled from the front of the truck.
