John Deere Engine

I painted and reassembled the engine. Here are a few still photos. I'll do another video later in the week.

I've been a JD mechanic for 35 years, & I have no idea what the hell an aspect ratio is... ...but I like the engine..sounds like a John Deere...good work.

Thanks, Ron. The video was shot in a wider format, but when I loaded it on my computer it made the video narrower than it should be. It basically makes everything look skinnier than it really is.

Thanks again, everyone for the compliments.

Wow...... That really does sound like the real deal ;D Looks mighty fine too.

I saw your engine running and read the name and it sparked off the memory of the vid' I took last month, I hope you don't mind Chuck, I think this will show just how well your sound is to the real one! (the only difference... Yours doesn't miss fire )

I had never seen this type of engine before so I loved the sound and took a couple of photo's etc... Then you made a miniature one.... Fantastic ;D

Nice unstyled D, Ralph...I have to say, the ol' gent fueling it while it's running would get a severe warning from the safety police at our show-that's a no-no...

 

[Divided He ad]

A no-no... Your not kiddin... You should have seen the flames coming out of the inlet!!!!!!!!!!!!!!!!!!!!
I was trying to get a good movie of the flames and then he just happily climbed up and starting fueling!!
Hey he owns it, if he feels happy doing that I wasn't about to try to stop him... These Welsh farmer types can be pretty phlemy when they snarl at you in their native tounge

I really did like the engine, got 2 stills of it too.

Hi Chuck, I have watched & listened to your JD video several times.
A couple days ago I was at a friends house when he had someone plowing snow for him. He was plowing with an older JD. As I watched and listened to that old JD, I thought of your engine. Today I watched your video again and you hit that sound right on. It is really a distinct sound.

I would like to try to build your engine. Do you have any plans or prints that you would be willing to share?

yet again another great engine chuck :bow: Thm:

I don't have a formal set of drawings for this engine, but might be able to pull together some of my working drawings.

The old John Deere engines, were two cylinder horizontal inline designs. To greatly reduce vibration, the crankshaft throws are 180 degrees apart. Since the engine is four-stroke in operation, the engine fires twice, at 180 degree intervals, during 1 revolution, then coasts during the entire second revolution. This is what causes the syncopated sound when the engine is running. Here is the Youtube video of my engine running:

Other tractors and engines that use the same two cylinder firing pattern are the Waterloo Boy:

And a rare old tractor called the Pull Sleve (love this one):

I'm sure there are a number of others, but these are the main ones that I've found.

Chuck,

Looking good. You are making it to easy for everyone. I had to make the engine with a few pictures and a few drawing you provided me.

Here is my engine

 

[cfellows]

Hey, Dave, that's looking good. Looks more like the first JD engine I built (My Avatar). I see that you put the timing gears inside the crankcase - I like that. I'm a little puzzled by the valve arrangement. What are those brass tubes coming out the side of the valve assembly? It looks like you are using a sliding piston exhaust valve arrangement. Where is the exhaust?

Chuck

 

[dreeves]

Chuck, yes I am using the slide valve. The exhaust comes out between the cylinders. You shouls be able to see the holre on the top of teh cylinder,.The the tubes that are on the side of the heads are the airtubes to get air to the valve. I did not want to make it that way but there is little room in the head. I am going to remake the head to use the ball type you are using. I will try to post a picture of the head so you can see the way I made things.

 

[dreeves]

Here is how I made the Head.

The cad shot shows the head cut along the center of the intake and the exhaus. The left head part shows the rear section of the head which holds the slide valve. The bottom was pluged after the valve and spring were installed.

the right one is the intake which lives in the front half of the head. The holes go to the center of the two secondary heads which hold the valve. The valve opens and lets the air behind the valve and into that tube that chuck asked about. the second picture shows the setup so you can see how little room there is in the head. there are 22 holes are in the head.
