    6V to 12V conversion

    Howdy. I have a question that isn't truck or tractor related, but I know that quite a few folks around here have lots of experience with older equipment, so I'd like to ask some opinions here. My brother just bought a 1948 Studebaker Starlight Coupe (Champion). It seems to be in reasonably...

    JD3020 fuel guage

    Or the wire to the sending unit could be shorted. Disconnect the wire from the sending unit. Disconnected, it should show empty. Grounded, it should show full. If that"s the case, then you have a bad sending unit. If the gauge doesn"t move by alternately disconnecting and grounding that...

    JD 4630

    Sounds to me like the brake pads are coming apart. It's pretty common on those old row-crop tractors. The pads will come apart, and the material will plug the suction screen. An easy way to check is to drain the hydraulic oil and pull the suction screen. If the screen is clogger with thick...

    4010 Hydraulic Problem

    Sounds to me like your couplers may be screwed up.

    Fuel in oil on Detroit Diesel

    Glad to hear that you found where the leak is coming from. I'm no expert on the 2-cycle detroits... WAY before my time for the most part. But I don't think the injector sleeve is going to cause the injector to leak fuel. I think the injector itself is leaking. I seem to remember that you...

    Fuel in oil on Detroit Diesel

    Lots of parts stores sell ultraviolet dye for a/c systems. I wouldn't try mixing that with fuel... but I've seen cheap ultraviolet flashlights for sale in the same section. Never used one, but I imagine it'd work for you.

    Fuel in oil on Detroit Diesel

    You need to get a black light and some ultraviolet dye. If you call around to some good auto parts stores, you can probably get a black light for under $30. You can get ultraviolet oil dye (works fine in fuel, too) at a Cummins, Detroit, or Deere dealer- it’s fairly cheap. I mix it...

    Frozen top link on 4430.

    I like the diesel fuel idea. Never tried it, but it sounds like it'd work. I've broken loose several frozen top links much the same way that others here have. Lots of heat, vice, cheater pipe, etc. Then wire wheel the rust and put antisieze on it.

    903 cumminns

    I wouldn't touch that with a ten foot pole.

    JD 4630/4640 15 speed powershift?

    +1 on everything msb said. You'd be opening a huge can of worms... and would be time and money ahead to either fix what you have, or buy another tractor.

    2955 or 4040 part 2

    If that compressor is locked up, then the fix will be a bit more involved than just bolting on a new one. You really need to remove the expansion valve, flush the system, and replace the dryer. Not too hard if you've got the equipment to do it... but time consuming. And those compressors...

    John Deere 8640 questions

    Forgot to mention... the engineer who designed the basic configuration of these tractors should be flogged. If you want to remove the hydraulic pump... you have to remove the whole front end of the tractor (hood, radiator, batteries, frame rails, counterweight) all as one piece. Not QUITE as...

    John Deere 8640 questions

    Run away! Those things are a money-pit. I worked at a Deere dealership for several years, and we always liked to see these old 4wd's come in the door. Even if you THINK it's in decent shape, chances are it needs thousands of $$ worth of work. It wasn't uncommon for one to come in with a...

    2955 or 4040?

    I"d definitely go for the 4040. It"s built heavier, has a wet clutch, parts are cheaper, and it"s much, much easier to work on in most cases.

    How bad have I messed up?

    Buy a Craftsman telescoping magnet. I've fished a few parts out of nasty places with them over the years. You've got to be careful bending them, as the brass is a bit brittle (you just have to put small kinks in the segments)... but you can bend them a fair amount if you're careful. And best...
