JD B question

sready · Sep 5, 2013

Could anyone please help with a question? Am I correct in understanding that my 1942 JD B serial no. 132161 does not have a water pump? Also, I am now at a point where I am thinking about paint. This tractor was repainted 30 plus years ago. The paint is faded. Would anyone recommend just repainting the sheet metal?

You are correct on the assumption that the B does not have a water pump. It should be "Thermo-siphon" cooling, which means the warm water rises, and enters the top of the radiator where it is cooled and drawn back into the engine's water jacket via the lower water pipe. If I were going to paint the sheet metal, I would just repaint the whole tractor. Just my opinion.

Thanks for the information. Are you against sand blasting the tractor? Or spend a lot of time with wire brush on a grinder?

old popper · Sep 5, 2013

Yes, I am against sandblasting the tractor. Sandblasting will stretch and/or deform the sheetmetal, and I feel that sand gets in where it should not be on the rest of the tractor. (again, just my opinion)

What is your recommendation for cleaning up the engine, deck and other places for repainting?

Keep in mind that it is your tractor and do with it as you please.

The wire brush on a grinder works best for me to <a href="http://www.youtube.com/watch?v=ufkD9Do7Gf8&feature=share&list=UU4gFuJx6qHbiK0FRREh2lDw">"spruce up" a tractor</a> to get it ready for <a href="http://www.youtube.com/watch?v=XJ9PLo2bRqk&feature=share&list=UU4gFuJx6qHbiK0FRREh2lDw">eventual field work</a>.

Have recently started removing and sand blasting blasted all wheels before painting.

Hope this helps and good luck with your Model B.

You might consider using some type of "degreaser" and then a "spray wash".

Using various sizes of wire brushes in the hard to reach places have also helped.

Thanks
I don't know yet what I want to do. The tractor was painted about 35 years ago with a brush. How terrible would it be to spray prime and paint it after a good cleaning?

on the ones i paint i use air craft stripper to get rid of paint then pressure wash then wire wheel and clean it real good the more prep work you do the better job it will be

If you are happy/satisfied with your work and it suits your needs, then that is all that counts.

"Easy" is our 46 A that was spray primed and painted after a good cleaning; this tractor was "easy" to spruce up.

sready · Sep 5, 2013

wow, that looks great! All you did was clean, prime and paint? This summer I used Dakota Shine on my 4440 and 4450. They turned out well. I might at least see how it looks.

James Howell · Sep 5, 2013

Yes, clean, prime, and paint seems to work best for our purposes.

Using used Dakota Shine on your tractors sounds like a good idea.

thanks for the discussion. Cleaning and refurbishing the paint first is cheap and easy and may work.

A good cheap way to prepare the sheet metal for paint is sandpaper and elbow grease, but not just any sandpaper. Go to your auto parts store and get a roll of adhesive backed 6" sandpaper for a DA. (dual action sander) Get a roll of 80 grit for the heavy rust and a roll of maybe 180 grit for the thinner paint and light rust. Get the good stuff, not the cheap stuff. I have a DA and I do use it a lot but sometimes I just rip off a piece of sandpaper from the roll, stick it to my hand and sand away. It doesn't take much work if you use the good paper. The 80 grit will leave scratches that show through the paint so you might want to follow it up with the 180. For the cast, James' way pretty much sums it up. Degrease well and paint.

One time when I was sandblasting I grabbed a flat sheet of scrap tin and played with warping it different ways with the sandblaster. Anyone who wants to sandblast should do this first before they blast away on something light. Hold a 12"-18" diameter piece of light tin with one hand and sandblast away at it. You'll be surprised at how much it warps.Jim

I'll add my 2¢ here. Brush painted tractors have a character and novelty that you don't see very often. If the paint is sound otherwise I'd be tempted to leave it alone. A rag with a little kerosene will bring out the color if you want to spruce it up for a show or parade.

If there is still some paint left, buffing compound or rubbing compound can re-brighten faded paint by removing the oxidized paint. Work carefully to avoid taking off too much paint on the higher creases. Less work and cost than re-painting.

There are some relatively small areas where the paint is gone. What paint will match the green? I touched up my 4440 with a can of JD Green (their brand) and discovered it is a little lighter in color?
