The TD 24 lives again! 

Thank you for the encouragement! There will be more videos in the future.

Thank you for the advise. We have had it running on gas several times now for a couple minutes intervals. Check out our video of it running.

@@littleoak6129 Yeah, I saw it, and you guys did a great job on her. Are the plans to leave her as-is, or restore her to Army new?

More to come for sure Steven!

@@littleoak6129 Seriously, please keep posting more on it ! Regards from Alaska!

Hi Murphy 👍😁

Thank you! Yes the fuel system on these things is very different.

Question why did you start it on gasoline at first just wondering?

@Jambo thank I did not know that. That pretty kool

Check out our clubs Facebook page, Pine To Prairie Tractor and Gas Engine Association, and maybe consider a membership.

It’s quite simple. The heads have a remote chamber that is isolated by a single poppet valve. The carb is connected to this chamber via small passages cast in the head. When the compression release is pulled, three things happen. The poppet valve is opened, which lowers the compression ratio to 5:1. The butterflies in the intake manifold close off the main air passages, which all intake air thru the carb. Lastly, the ignition switch on the end of the butterfly shaft switches on the ignition. She will now run like an ordinary gasoline engine. When diesel operation is desired, the compression release is pushed in and the poppet valve closes, raising the compression ratio to 15:1 ; the carburetor and ignition are also shut off . At the same instant, the diesel speed control is raised to about halfway so fuel can be injected for diesel operation.

I should add that the spark plug is threaded into the remote chamber, so it won’t be fouled during diesel operation. Also the starting poppet valve does not continually open and close during operation, but remains stationary, whether in the open or closed position. It’s only purpose is to control the compression ratio. It is controlled by the operator via the handle thru the dashboard.

Haha the Fitz would be a little bigger undertaking I think! We were completely blown away by how clean everything was inside. The engine was completely free when it came up.

How do I find your website or club?

Is more common to use small two stroke engine for starting. Rust is no problem in mud, because there no oxygen.

You don’t have much

The guys got her moving under her own power last fall. They drove it into a machine shed for the winter. Work will continue this spring. Unfortunately nobody got a video when it was moving. But I will have more video this summer

As of now it's all the farther we are. The guy who's been doing the majority of the work had some major surgeries it was out of commission for quite a while. Work will be started again this summer. Keep an eye out for more videos.

you'd be surprised sometimes, I doubt much in the way of solids would have gotten into anything, but I'm sure water got everywhere it wasn't supposed to

yessir

Looked like new inside. The picture of the valves in the video is right after we took the cover off.

The project is kind of on a hold at the moment. One of our guys is laid up from multiple surgeries and others have other priorities at the moment.

We are hoping to have more for our viewers this summer

@@littleoak6129 good to hear!

It will be at the show this coming weekend, August 13th and 14th. Hope you can attend.

Built from 1947-1955

I had a Super M-TA Diesel (1954 tractor). They were started on gasoline, when the engine was warmed up, you pulled a couple of levers and it then ran diesel. Guessing this is the same design...

I'm personally not involved with the restoration project so I don't know how they did that. I think it was kind of a hassle for them. I'm seeing some of the guys this weekend and I'll try to remember to ask.

Nothing could be easier. Get her running on gas and after a minute or two, open the throttle and wait until white smoke appears at the stack. Not knowing what you are starting from, start at the tank and clean everything that the fuel flows through. Clean the petcock, use new filters (the filters are also bled with the engine running on gas) , the water trap should be spotless, and make sure there is oil in the injector pump. Ordinarily once the filters are bled , the rest of the system takes care of itself. But in the case of a dry start (rebuilt injector pump) , you may have to crack the high pressure lines at the injectors to hasten bleeding. If you still have no fuel at the injectors and you are certain you have the rest of the system clean, then the pump has some mechanical deficiency. Hope this helps

Josh Ryan, my explanation was under the assumption that the gasoline side of the engine is operational. It can be bled and started, even operated on a regular basis, with the gasoline side inoperative. But it is SOOO much harder that way. My advice would be to get the gas side running first, then 80% of the problem is behind you.

@@richardmaurer9002 It will be coming out of a complete restoration at that point. Thanks for the advice.

@@richardmaurer9002 yeah, in 30 years I've never had to crack an injector line on a ud-14a. Just open the screws at top of each fuel filter until fuel starts coming out, close em up, wait for fuel pressure to build up, and away she goes.

Sure would

There is no separate engine , or “pony”. The same cylinders burn gasoline as they do Diesel fuel. The cylinder head with its unique induction system is the heart of this starting system.

@@richardmaurer9002 Yes this one's the same at the TD-18 I ran, oh those many years ago. We'd start it up on gasoline then when warmed up, we switch on the diesel fuel at the same time as shutting off the gasoline side. It was a pretty good set up I thought, no racket from those pony motors on the International TD's!

Cat had a primitive pony motor...this inline 6 had spark plugs to start the engine on gas and switch over to diesel. Very advanced and unique

@@regsparkes6507 was this because the starters weren't strong enough to turn over the high compression diesel directly?

@@86FxBdyCpe Steve, this starting system was used because back in those days, it was easier to start and warm up the diesel engine. The gasoline fuel would ignite on much lower compression and therefore was easier to start. After warm up when we would switch over to diesel by 'throwing' a lever which would let the valves close fully, increasing the compression which is what diesel fuel needs to ignite/start and run. Sounds complicated maybe, but in fact was very simple, and effective too.

They start on gas then switch over to Diesel! my guess is they are trying to the diesel system working!

Pony Motors Gas Motor warm up diesel engine

@@jamesmcguire1178 the TD24 did not have a pony motor! the Diesel motor had spark plugs and started on gas then was switched to diesel!

@@ejsayler1 Then why does it have two exhaust pipes?

@@Frank-Thoresen It was to reduce exhaust back pressure to help with cooling!

Yeah sorry. That definitely wasn't my choice to put that in there. RU-vid does what they want with people's videos. There supposed to be paying us for the adds they put on our videos but we have yet to see any $.

If you got a Biden advert, it’s because the algorithms decided your a potential Biden voter, nothing to do with this channel, is your browsing history, and tracking that determines the adverts you see 😂

@Hagen van Tronje Yeah, that’s not going happen, enjoy socialism comrade.

Get over it...

Thanks Brandy. Keep an eye on the channel. There will be more videos in the future. We do have it running. Check out that video if you haven't already.
