Thanks guys! Mounted my nice ford 'heavy duty' oil bath air cleaner onto a down pipe to my turbo. Welded a sturdy bracket onto it and painted it. New clutch is buttoned up with trans back on and now I am obsessing about hydraulic slave cylinders and radiator hoses. I plan to push in the clutch master cylinder push rod with the same leg off the clutch pedal Henry used. That puts the master cyl down on the frame rail so I'll get one with a remote resevoir. All 3 pedals will be bone stock in the cab. I just mounted a shifter knob from a T9 crash box on the gm transmission. I also plan to keep my ford instrument panel all stock, using flathead senders. The truck is already 12 v with the resistors. Pictures tomorrow.

The Diamond T truck company used the hurcules line of engines in their trucks. Diesel engines as well.
Some of these trucks and engines were quite big for the day. Many were employed in WWII for taking wrecked tanks off the battle field.
A good friend of mine that served in the army during that time had said the injection system in the early years was the weak link to the diesels.
Long before my time. But interesting.
I'm very much enjoying your project.

Very, very cool! Remarkably like my own. That's a 2 door or perhaps a 3 door, but so much is similar! I wonder about it's history.

GB, I am concerned about your choice of air filters for your 6AT installation. Attached is a link to an old Cummins video about the damage dust can cause to an engine, https://www.facebook.com/liftedlife...real-throwback-1954-eddition/461266004382770/. If the link doesn't search for Cummins Operation Hourglass.
There was also an SAE paper written on the development of that engine back in 1985 if you would like to know more of the technical details of the engine. The SAE paper number is 850260.

Wow, thanks for the warning. I have heard about turbos getting 'dusted', but have also heard that an oil bath air cleaner is a very good scrubber of air, but not as efficient as a modern paper element. I will use what keeps my engine working right even if I have to go 'modern. How do I get that sae paper? I will google it. I'm waiting for ups to deliver my wilwood 'pull type' clutch slave cylinder and master cyl for the frame horn and a braided steel cable to mate them. Still working on my remote spin on oil filter setup and need some creative radiator hoses. Then it's fire up in the frame time. I plan to roll it outside, warm it up and gunk and clean the engine on some sunny day.

EDit: Just in case you thought my wife was 'running off', I didn't mean it literally. We just stayed up watching old country videos on youtube.... OK, just to be clear.
I just downloaded and printed the SAE paper on the onan/cummins L series engine development. Seven big main bearings, water cooled oil cooler with 20 plates on the turbo models, 6000 hours-20,000 hours between overhauls at 3600 rpm. Not sure I can wear it out on casual weekend runs or to the dump, as I am 67 years old in May. Running the fine line on weekends between my wife running off, and me being happy with what I got done on my project. We both agreed about 10 minutes ago that I was obsessed. But we Knew that...... Just about ready to fire up the Cummins 6at in the frame.

I know nothing of diesels other than to me thay smell bad. Hope you have a fan to get the stink out of the shop and for safety a fire extinguisher nearby. Perhaps you could post a video of a smooth purring kitten idling in the shop. Looking forward to a trip to Orcas Island this summer.

Now you know a little more about the engine. I agree you will probably not run it enough to wear it out, but UPS probably put 15-20 years worth of wear into it before disposing of the truck. I look forward to seeing it run.
Diesels don't necessarily smell bad, just different.

Most of them came available in the early 90s..... The engine I have was built in '88. Seems the drivers staged a revolt against the clattering, rattling noise in a tin can of a ups truck with the engine between the seats making it hard to think. My wife didn't like my last 6at conversion and I don't expect her to like this one. I have a bunch of trucks, all single cab. This one is for my guy time. Cummins specs call for 57 lb oil pressure and that is exactly what I have. I hgave plastigauged the mains and rods and it is exactly at factory specs......

Been running this contraption in the frame over the weekend. The hydraulic clutch is ready to bleed, the remote oil filter all buttoned up, alternator wired etc. etc. If it had a steering box and a wheel (or vice grips)I could rig up a seat tomorrow and drive it around the property. (with no brakes).... The clutch master cylinder is on a bracket bolted to the two diagonal horn mounting holes on the left frame rail. I used a piece of light weight 3/4: dia steel tubing for the long push rod from the clevis on the stock clutch pedal. Threads at both ends. Braided steel line crosses under the pan to the slave cyl on the right side. My son is working with me tomorrow so I hope we can pull it out of the dark cave we call a shop and get some pics or better yet a video. With sound. There is a lot of sound involved with a 2' straight pipe. And yes it smells pretty bad running it in the cave unless of course you like diesel smell. Oh, and I have yet to drill even the smallest hole in the frame.
