Cool truck! Your Kenworth has the "low mount" radiator, which was available up through 1956, I think. That Cummins has a double-disk (DD) fuel pump. That pump and the single-disk (SD) pump can be tricky to work on but some people are able to run them in their antiques. Converting to the PT fuel system is typically the more popular route. There are definitely Jakes available for your engine; the 743 cubic inch NH block was used in quite a few Cummins models. I think it would be a model 20 Jake. If you want to install one, I believe you will need to convert to the PT pump and injectors. The transmissions were probably made by Spicer. The truck looks pretty stock overall which is cool. It looks like the 220's block was cast in July 1964, but the same basic engine did exist in 1949--it was known then as the NHB-200 (direct predecessor to the NH-220). The brakes look like S-cams to me. Spring brakes can be installed, I don't know the process of switching out the brake chambers though. The old style chambers on it look pretty cool along with that Tru-Stop hand brake, but parts availability and safety are definitely things to consider. Your truck has Kenworth torsion bar suspension, which is neat. Even the fuel tanks and air cleaner look stock. You shouldn't have much difficulty installing air seats and you can get old hardware like door handles online.
Thank you for the info! i'm hearing that if the injection pump runs out of fuel it will run away. Also i'm having difficulty finding how to shut down the motor. like do i pull the decompress? There's no shut down wire or cable that I can see. im worried that if i start it i wont be able to stop it.
@@WestMichaganCraziness Glad to be of any help. The engine will run erratically if air gets into the fuel system, it messes with the metering. These pumps do have an emergency shutoff valve. I think it may be the thing that the long coil spring is hanging from but I could be wrong. If that doesn't work, you can pull the compression release to kill the engine. There's a priming procedure to purge the injector lines of any air prior to starting, so that there isn't a runaway. The supply lines that go through the heads to each fuel injector have to be disconnected one at a time. Once you disconnect one supply line, you use that little hand pump that's next to the oil filter (?) just aft of the injector pump. If that hand pump isn't seized and still works, pump it until you see only fuel coming out of the disconnected injector supply line. Reconnect that supply line and repeat this procedure for the remaining five injectors. I've left out a number of steps that come before this. There is a procedure to prime the pump before you even get to purging the injector lines. This procedure is important because this pump uses two sets of spring-loaded disks that rub together to distribute the fuel from a variable-stroke metering piston. If these disks spin without a film of fuel on them, they will get scored and potentially be ruined. Look at this thread for some info: forum.aths.org/108139/Cummins-double-disc-pump-troubleshoot-questions On page 1, the user named Aaron posted four scans from a Cummins manual that will be helpful to you.
@@WestMichaganCraziness It's interesting that this engine has a block that was cast in 1964 but also has the old Double Disk injector pump, older style intake manifold with caution and firing order tags, and older belt-driven Bendix-Westinghouse air compressor. This compressor has the unloader valves worked by a rocker arm on top. It's almost like a bunch of older parts from one engine were put onto a newer block. The PT pump and injectors went into regular production in 1954, which almost instantly caused the end of production of Single Disk and Double Disk pumps. The early PT systems did have a number of problems and there were some operators that stuck with the disc-type pumps, even installing them on newer engines. Do you know when your truck last ran?

@@waukesha398 Good to know that I can pull the decompress to shut the engine down. Is that the normal way to shut it down or is there a shut down cable that's supposed to be on the pump somewhere? Sadly the little hand pump is seized and doesn't work. I have a small 1 gallon tank on a ladder 10ft high. I thought that gravity would force the air out of the lines as I took them lose. Which did work and I have fuel to the pump but I'm not sure if any got up into the feed lines to the injector because I have not taken them lose yet. Can I use that method? or do I need a pump to get the air out?
I've heard that my engine is a jungle of old parts. I guess it worked, it was last on the road commercially in 1972 and last ran about 10 to 15 years ago I've been told.
The rear suspension is a torsion bar suspension what I would do is use a frame and suspension from a late model kenworth w 900 to make it safe big joe materno did this with his 54 kenworth which is operated by western distribution in denver colorado his is a working truck and show truck
Those parts are gonna be hard to fine should cool looking truck the way it is but lower have mercy when you get through with it or with it what a truck you will have
GREAT TRUCK!!! Just dig on these ol KWs! Make er how ever ya see fit! Hope we get to see her rollin!

Beautiful tractor..built right..all steel ..
Tractor😂
The twin stick set up appears to be a 4speed with 3speed auxillary transmossion

Oh way kool I subscribed. What's the plan's for the ol gal?
The rear ends appear to be Mack drop ins. You can contact PacCar with the serial number and they will tell you what parts you need.
Ggod luck.
Those parts are gonna be hard to fine should cool looking truck the way it is but lower have mercy when you get through with it or with it what a truck you will have
You will need to change the head for Jake brake
It's a addition to the head on valve cover I thought. Bolts in type of thing.
Those are s cam style brakes
Any simple way to replace or get them working again?
