Introducing the 502 Diesel...

[bell 11]

Here's what I started with... A slightly weathered 502...

[bell 11]

The engine. A Yanmar L40AE (4hp) with recoil start only.

The necessary frame modification. Not wanting to raise the hood (at all), I welded some plates in between the frame rails to accomidate the diesel's mounting holes. I moved the engine as far forward as possible, and can now slide a battery RIGHT in the battery box... Just in case I should happen to add electric start.

Here it is in "test mule" stage... Complete with the J.C. Whitney adapt-a-kit and test pipe!

The completed 8-speed conversion...

I used a 3" pulley on the transmission and a 2-1/2" on the engine to speed it up a little. It moves pretty good now! When you let out on the clutch in 3-HI, she's rollin coal...

Calling it done for a while... Everything works well and this tractor is LOTS of fun. I had originally planned on a total repaint, but I think it is going to stay this way for awhile. The rustic look is really growing on me...

[DMK855 15]

I like it Bell!!!! :omg:

[Confused99 2]

Jon that is just to cool, great job

I also like the rustic look!

[dclarke 4,044]

another interesting project that turned out great Jon. i like it the way it is. can't wait to see what you do next. :omg:

[stevebo-(Moderator) 8,362]

That little motor fits in here nicely !! What are you running for an exhaust??

[rickv1957 72]

Looks great,like the original look!! Rick

[DoctorHfuhruhurr 137]

Nice. Is that a Harbor Freight Sand Blasting Cabinet I see? :omg:

[bell 11]

Thanks fellas...

I don't have any videos yet. I haven't figured out how to do that one yet.

It seems to have plenty of power. I haven't hooked to anything yet, other than a dead Raider 12 I bought at the Elnora swap meet. It pulled it with ease in 3 high...

Gene, I guess it would be a 402, but the horsepower is 4.x, so I'm going to round up to 5...

The exhaust is a slightly customized Stanley tractor muffler... model AC-1. It is for small AC tractors and is for 1-1/2" pipe.

Not a Harbor Freight cabinet, I got it from www.summitracing.com It was cheaper than anywhere else and nearly free shipping.

Great project.

What is the barb fitting on the gas tank?

[Raider12 13]

Very nice job. :omg:

[bustedglass 1]

Bell, that thing is Bad A$$.

I love the stack, I love the duals, I love the front ags, I love the "aged" look. I just love everything about it .

I too cant wait for some vids. Find someone that can help you with how to make vids, and "Share" it with the rest of us .

I dont know who is doing the new calendar, but that picture by the water pump is a 2011 Calendar picture - FOR SURE !!!

You "Hit the Nail on the Head" with this one buddy .

[bell 11]

Thanks fellas!

The barb fitting is for the fuel return line. It sends excess fuel from the injector back to the tank.
