High Pressure Oil Pump question
Can someone tell me approximately how long it takes to remove the cab to work on the engine? We are having to have the High Pressure Oil Pump replaced and our warranty company is saying that this entire process should only take 5 hours. That sounds unreal to me! Please advise!

if all theyre doing is replacing the HPOP they shouldnt have to remove the cab. but does take some time to remove the cab and put it back on. if its still the factory setup (as in someone hasnt done alot of mods) you could probably do it yourself in 5-6 hrs depending on how well you know your way around the engine. remove the turbo, and sometimes the intake manifold depending on the year and style and your right there at the pump. just have to remove the cover replace the pump and reassemble.

As said above, pre 05, the pumps weren’t as reliable. In 05 they changed the pump design which essentially fixed the reliability issue. In doing that, they redesigned some of,the HP connectors which caused a few other problems that manifest as low psi in the HP oil system BUT aren’t caused by the pump. There is an STC fitting (snap to connect), stand pipe, and dummy plugs that commonly fail causing low pressure via leakage. Ford (international) released redesigned parts for each of these to fix the problem. All these parts need to be installed in order to make it reliable (e.g. just fixing a one leaking standpipe will have you back in the motor again when the other parts that weren’t replaced fail). Sometimes these warranty companies only want to pay to fix the immediate problem so be aware.
If it’s an 04 or earlier it’s probably the pump. 05 and laters rarely have pump failures. If they are trying to change the pump on an 05, than you probably need to find a shop that is more skilled at working on these engines since it’s likely misdiagnosed. Also IIRC the entire cab removal and reinstall takes around 4.5 hours per flat rate manual. I haven’t neard of anyone removing cab to replace the pump though. If it’s an 05 or later model, buy an egr delete kit or BPD egr cooler to have them install it out while apart as the later model coolers are prone to leakage and there shouldn't be any additional cost to change it out while everythings apart.

Go buy the STC fitting, stand pipes and dummy plugs and do it yourself.
the 05-07 pumps are so good, shops that know.... Buy them to put in trucks because of mis-diagnosis!
ask if they did a pressure reading and then ask if they checked on any updates that model year may have needed and then tell them to read up!
I would not let them pull the cab and possible not even touch the truck. Then ask for your money back for diagnosis... a simple test of the high pressure system with air and a live reading of the ICP sensor would have found that issue.... 30 minutes tops!

Did you actually confirm a broken shaft?
Your earlier post seemed to indicate that you did not or could not verify that this was actually the case.
"I know very little about the internal workings of the hpop. They told me some sort of shaft broke on it"

Bismic-I did a little research when it happened. The shop that fixed it specializes in 6.0's. Even they were surprised that the shaft broke. That's why they saved if for me to see. I've got a little over 248k miles now. It broke while I was accelerating. The engine just shut off. I assume for no oil pressure. I thought maybe it was low on oil and added some but of course that did not work. They did check the pressures to diagnose before they dug into it. I think they said one of the readings was at 0 so indicated that it was not pumping at all. I probably would've tackled it myself but have a full time job and lawn service too so that was not an option. They even did an oil change since there might have been some metal parts that may have gotten into the oil. Have not had a problem with it since. I always appreciate your input since you know way more than I do about these engines.
