My 2009 Ford F550 Cummins 6.7l Transplant story #1
I am going to use this thread to document the history of my 2009 Ford F550 that I use to pull my 40-foot fifth wheel camper. The story starts with a Ford powerplant but will end with a Cummins so please stick with me, I know that this is a Cummins site. This will be a work in progress but I want to capture any info that someone else trying this swap, will have enough info to know if they want to try it or not.
In the beginning:
1. Purchased 2009 Ford F550 gas V10 6.8L with no bed.
2. Built (mostly) bed to mount fifth wheel hitch and hang some toolboxes from. Plan on doing a diamond plate skirt and rack, just not there yet.
3. Found a fuel injector stuck open and dumping fuel. Replaced all injectors but MPG only changed a bit. Still about 4.5 MPG while pulling my 16k pound camper.
4. XL stripped truck but I wanted PW, PL, and power mirrors. Stripped the truck down and replaced the dash and floor harnesses with new Ford parts found online. Door harnesses were used.
5. Ordered new SRW conversion wheels from ****. After 11 months, never got them. Ended up ordering from another company, had them in 5 weeks!
5. Still has the DRWs but that will change.
6. Several thousand miles with the V10, a full West coast trip over 6 months and a Texas trip over 6 months. The only major issue was a blown transmission in Seattle on the first trip. Minor issue, 4.5 MPG.

Re: My 2009 Ford F550 Cummins 6.7l Transplant story #1
After almost 10K miles of pulling 16K pounds around the country, I found the gold nugget. A 2018 Cummins 6.7L out of a wrecked 2500 with only 1000 miles. Now it is time to start gathering the rest of the parts.
1. Found (used) adapter plate, flex plate, and motor mount adapters (Destroked) from a guy off of Craigslist.
2. Engine came from a wrecking yard that shipped it in. It had the ECM and harness but was missing the turbo and a few small parts.
3. SwapHelper was needed to get the 40 minus 2 tone count that the factory ECM and tach needed.
4. Power steering pump mount for a F550 (DCS).
5. All of the parts in the front to convert it to a diesel truck (radiator, condenser, inter-cooler,...).
6. Shortened/lengthened driveshafts.
7. Dodge Ram accelerator pedal. Not sure if I need this yet, will discuss this issue later.
8. Lots of electronic tools and software.
9. Ram flex downpipe. Little close to the transmission lines but will check the temp after a good long run.
10. Possibly a PCS Transmission Controller. Trying to keep the Ford ECM for now if I can but that is still i the works.
11. ECMs and engine harnesses for several versions of truck.
12. I am sure there is more that I am not thinking of.
Some of the general lessons learned:
1. Trust but verify. During this project I have heard a lot of "that will work" or "that should work". All I can say is verify!! So far almost everything that I have asked about, turns out, won't work. The more you dig in and the more knowledgeable people you find the more you figure out the impossibility of what ever you are looking to do.
2. When it comes to ECM configuration/updating/tuning, there is a lot to know. I am not looking to make a complete monster out of this (yet), just a stock tune with deletes that support the truck. You might as well be asking for the keys to the Taj Mahal. I have armed myself with a pretty good arsenal of tools (Cummins Calterm, Insite, EFI Live, Kess) and it looks like it will still be a while to figure it all out and getting help is either very expensive or non-existent. Turns out a lot of the information that I am looking for is the livelihood of these engineers, so I completely understand.
3. Give yourself plenty of time, don't schedule camping trips that end up causing stress.
4. If I were to do it again, I would start with an older CR or even a manual pump motor. The later CRs and their ECMs cause some issues/complexity with the swap.
5. Keep every single wire, bracket, nut and bolt, you will probably need it or some part of it.

Re: My 2009 Ford F550 Cummins 6.7l Transplant story #1
After ordering my SRW conversion wheels from "unmentioned" company, I waited for 11 months, and still no wheels. I called up Wheels Now Inc. They didn't have the specs for the needed wheels so I provided the info that I knew. The were out of the 19.5" blanks at first but got them back in stock pretty quick.
After a few back and forth email, we got them through engineering and in line to be built. About 7 weeks later, my new wheels showed up. Went looking for some H rated tires with some tread and ended up with the Toyo M-608Z.
To get the full carrying capacity of the truck, the H rated 285/70R19.5 (6400LBS) tires is what I needed. Took the wheels down to the truck tire shop in Denver to have them mounted up and balanced. He gave me the good news that he was going to discount the install (by a bunch) which I was happy about.
Turns out that there was a reason. After paying, I went out to take a look. Seems that the guys working on my wheels thought that they were working a farm tractor and didn't really take in to consideration that I had just spent $2K on these wheels with the nice new shiny black powder coating. Now they looked like they belonged on a farm tractor.
Knowing that I could act stupid if I went back in, I chose to suck it up, take the lump, and drive off with my new tires and wheels. Now to get them on the truck.
Turns out the blanks that were used to build the wheels had a bulge to the inside of the wheel that just so happened to line up perfectly with my front brake calipers. Didn't seem to be enough of a problem that a flap-wheel disk couldn't resolve.
After a little polishing of the caliper, the wheels are on. There may be a 1/32" clearance, but it works. These massive wheels don't seem to flex at all.
Got on the highway for a test drive, and the truck now drove like a tractor, it was shaking all over the place. Next day drove it back to the tire shop for a check.
Things didn't go so well with that starting with lug-nuts that wouldn't come off of any wheel. Seems that my Craftsman impact gun was able to do an almost permanent job of putting them on and the tire shop couldn't get them off.
After a couple broke sockets and a bent up tire iron, we got them off of the truck.
Now off to the lounge to wait for the work to be done. Got work that it was ready to go, no money exchanged, and off to the house.
Not perfect but a lot better then before. I don't expect this to ride like a pickup so I am good to go. And for a side note, the wheels clock in at about 80lbs. and the tires are almost 100lbs, that puts each tire/wheel combo at almost 200lbs.
I bought a spare tire and wheel but if I ever have to change it there will be a call to AAA since I wouldn't be able to get the flat tire back on the bed of my truck.

Little close the bed but this is an F550. I drop the hitch of my camper, 2800lbs tongue weight, and the bed drops by an inch.
By the end of this, I will be installing a Kelderman Quad-bag four-link air-ride suspension that I picked up off of an ambulance.
I hope to lift it a couple of inches with that.
