Yes, the best thing with any crawler is to store it under cover, and up on boards or logs or something like that. There's just too many parts on a crawler that don't like exposure to water. ;) I hadn't thought about the tracks freezing to the ground, boards are a good idea in the winter. Anything s...

Ah, the magic oil fountain. I saw one machine that leaked thru the injector seal so badly that the oil level rose until it puked all the oil out of the engine. It had half the oil pressure it was supposed to. When we drained the crankcase nothing but diesel fuel came out! Leaking injector will more ...

Well I better take it easy going in reverse. I was backdragging to smooth out the ground, had it in 3rd gear backing up a grade and lugging the engine pretty good!

I'll look at putting a bolt in the R position.

Do the pads look like this? http://216.104.73.215/jdcrawlers/gallery/cache/Lindeman%20[1943%20~%201949]/600_image19.jpg I noticed while browsing the photo gallery that these tracks are different in that the grouser is to the rear. Most tracks the grouser hits the ground first. The main thing to look...

Also, do NOT (one says this a lot with this style reverser), ever, try and use the main transmission in reverse with the reverser in reverse to attempt to gain an additional forward speed. Guess what happens if you do? Why is this a problem? Because the reverse clutch isn't as strong as the forward...

You can get magnets on the end of a heavy piece of copper or aluminum which will go around parts where a magnet on a straight stick can't go. They're great. You can even fish around in an engine oil pan through the drain plug.

Thanks for all that info, especially Stan! I will look at the adjustment of the valves. You mean the rods with yokes on them? Definitely plenty of weight on the front, I was just thinking the smaller tracks are fine if it is purely a tractor. Where we were clearing the trail in the woods, it follows...

Name is Ray, I live in upstate NY. My father runs a machinery repair and fabrication shop on 22 acres, partially wooded, great home for a little bulldozer. A couple years ago a guy I know bought this 420c, serial number 109,464, and brought it in for some work. I thought it was the neatest thing eve...
