Hi, Oh! you're talking about the on-board generator polarity becoming reversed when there's an external charger attached. I think. Now that I've read it all again.... No, I can't see where attaching a charger, even in reverse, would wind up reverse polarizing the iron plates inside the generator. Fi...

Hi, Are you were concerened about causing a 'ground loop' current flow? If so, then you don't have anything to worry about. The case of the charger isn't attached to either the Pos or Neg output of the charger, so there's no association with which side of the battery is 'ground' and the case of the ...

Hi, All the early engines were thermosiphon. I think the Deere 40 was about the last of them, though. They work by the principal that hot water rises and cold water sinks. As the engine runs, it heats the water in the block and head, which passes thru the upper radiator hose and into the radiator ta...

Hi,

Well, that's eBay for you. Basically, if something smells like manure in any given auction, it's probably something you don't want to be stepping into!

And, nope. I'm not taking that bet with Lavoy, either!

Hi, Basically, ignore the temp gauge and wait for the coolant to squirt out of the vent hole in the radiator cap. That tells you when it's too hot and time to take a break. ;) Nothing like a simple thermosiphon system. No water pump. No thermostat. No pressurization. :) Just can't work 'em as hard, ...

Hi, Found it. Thanks! Once I knew who had posted it, searching for it was a lot easier. I found it buries in the buy & sell board. Here it is copied over, so when someone finds this thread in the future, they won't have to run the same search! :P Starting at#10001 to 16184/ 1965 . to 42485 /1966. to...

Hi, Just to make other folks shake their heads even more than they already are.... Ohms are the units used to measure resistance to current flow. Most folks have heard of these before. Mhos (Ohm spelled backwards - see we engineers*do* have a sense of humor after all!) are the units used to measure ...

Hi, I recall our old shop having several sets of these around. I suppose they got sold with the shop. At least, dad didn't have any (and he'd have been the most likely candidate to keep a set). Tools like these are always costly compared to what it'd seem they're worth because there's never very man...

Anyone have a JD350 serial number breakdown?

Hi, I looked thru this forum, and didn't see this question. I didn't look thru the other (early) forum, though, so I apologize if this is out here somewhere and I missed it. Anyway, I'm looking for a serial number breakdown for the JD350 by production year and variant (i.e. JD350, 350B, 350C, etc). ...

Hi, I just got off the SAME website, and it looks like the smallest one is 70 HP, which puts it into the JD450 class. I'd like something smaller, or at worst no bigger. So I'll keep on looking at used JD350 and JD450 machines. I'm not holding my breath that there will be a new small crawler from Dee...

Hi, The Yanmar is interesting. At least they have rollers on the bottom to carry some load unlike many other things I've seen. My ususal beef about rubber tracks is not that they're made from rubber, it that they tend to be wrapped around wheels without any rollers. So, the load is carried just like...

Hi, It's rather annoying to me that Deere has never made a 420 sized crawler in all these years since the end of the 1010 line. I can see where the market could well have dried up come the end of the 1010, but that was so long ago that most of the old iron is pretty well worn out. I'd absolutely lov...

Hi, No, silver is the best but it does have it's issues, one of which is that it likes to corrode. Gold is quite good, and has the advantage that it doesn't oxidize like silver, copper and aluminum (all better conductors) do. It has the disadvantage of being a lot more costly. We use it a lot in the...

Hi, Soak 'em in a puddle of water for a couple days, then drive around for a while. Water will loosen the rust scale better than anything and then running will drive it out between the pins and bushings. The bad part is that if you don't then use the machine enough, they'll just set up again. It hel...

Hi,

Just thought I'd point out that the model 64 blade for the 440 was a power angle tilt blade. Pretty sweet if you happen to have one....
