If you manually moved the gauge up the rpm scale did your indicator move back to zero fast and hit hard or does it come back slow. That would help me out with the spring tension. Thanks.

Can you fellas offer any advice on setting up the spring setting behind the faceplate? I cannot seem to get mine to read correctly, the rpm is all over the place and there is little spring pressure that returns it to 0 rpm. I moved the spring but where I think it should be it cannot go because of th...

Yeah, those pads look new, does someone have a secret supplier???

I always wondered how a electric winch would work on a crawler. I would of thought that the gearmatic (hydraulic) winches where rated for somewhere around 20-30 tons or so. I would be really interested how it works out!

I have never seen anything like that before! At least they got their money's worth out of that undercarriage!!!!

CaptainJoe, How's the cage project coming along? Any pictures yet?

There was a MC blade for sale in my area a month or so ago, in Pennsylvania. It was listed on http://classifieds.pennswoods.net/classifieds/index.cgi They are out there. Just not very often!

checked my notes, and my 420 has compression of 110 on #1 and 115 on #2. I used an inexpensive rubber cone type tester, so numbers may be off somewhat, but it gave me an idea of the balance between the cylinders. Paul Thanks Paul. I'm surpried that the compression isn't more of a published data for...

A lot of the time you will have moisture in the breather cap and pipe, but not in the engine itself. You have hot air escaping the engine through the pipe and breather which are cold, so it condenses there. Lavoy That makes sense Lavoy, Does the compression tests sound good? I cannot find any infor...

The thermostat on mine is literally a year old. What temperature did you go with? I want with 160'

Just re-did the leak down test and I made the changes on the original posting above.

I recently noticed a small amount of white smoke coming out of my oil filler tube so since we are having some warm then cold days in Pennsylvania I figured it was condensation, especially since I haven't been using my 1956 420 much lately. So I did a cylinder leak down test and a compression test so...

Come on guys its a antique! Antiques are worth alot of money!!!!!

Maybe we are all wrong, he says he replaced the water pump on the eBay listing. Maybe it's a 420 with a MC undercarriage. Who knows!

I don't see much chatter about the 430 Model, can a person still get parts for it? Other than the obvious track, rail and roller wear, are there any other problems to look for on the 430 when looking to purchase one? A good bit of parts are still available thru John Deere, there is also a lot of af...
