    4020 Rear Warning Lamp Wiring

    The rear warning lamp on my '68 4020 synchro is long gone, so I am finally gearing up to install a new one. This tractor always was equipped with just one rear warning on the fender, but I was wondering if it is possible to also put one on the other fender and wire them to operate in sync? I'm...

    Behlen Road Gear F20/F30

    A Behlen road gear from a F20 will not fit a F30 and vice versa, correct? I've read some previous posts and it sounds like they are not interchangeable, but just wanted to double check. Thank you!

    630 Rollamatic Spindle

    I am working on the front wheel bearings on a rollamatic 630. I discovered that the threads on one of my spindles are damaged to the point the castle nut will not stay tight. I was reading last night about the universal lock nuts/swagger nuts. I see I can buy them on a few tractor parts...

    Wiring/Lighting for 12v B

    My B is a 12 volt system with a three wire alternator. I recently got some headlights and a tail light. I am trying to figure out how to wire them up with my current system. I would like to put in a new three position switch. Been reading a lot of old posts and wiring diagrams on here, but I...

    B Governor Making Noise?

    A few weeks back I posted about a ticking sound I was hearing on the top side of a fresh engine and head rebuild on my B. I finally got the rocker arm rebushed and the surfaces refaced at the machine shop thinking that will finally solve it, but no success. So I took the governor housing off...

    B Engine Ticking Sound Stumped

    Folks I need some more help on an engine tick I am hearing on my recently rebuilt B. The overall consensus on social media pages is that it has something to do with the valves. I have readjusted them several times to 0.014 using the simplified way of adjusting 1,2,3,5 at #1 TDC and 4,6,7,8 on #4...

    Clutch

    I just ran into the same problem last week on my B. When I put the tractor back together I had some difficulty the last couple inches with wanting to go together easily, which should have been my red flag back then. With the clutch depressed it would grind and wouldn't go into gear. I had...

    B gears grinding after rebuild

    I finally got my B back together over the weekend after a rebuild and it starts and runs great in neutral. Last night I went to drive it out of the garage and it grinds in every gear with the pedal depressed. When I have the pedal fully depressed it even sounds like it lugs the engine down a...

    Broken crank pulley

    Dumb me dropped my crank pulley for my B. Is the chunk that broke off going to be an issue if I put it back on? Or should I just buy a new one?

    B engine front and rear seal plates

    I am reassembling the engine on my B after machine shop work. When I went to install the front and rear seal plates/cross braces to the block, I noticed that they both are sitting higher than the sides of the block. I installed them down as far as they would go with a block of wood and hammer...

    Painting inside of block after machine shop

    The block for my B was hot tanked at the machine shop and now I am ready to paint. What I am wondering is should I be painting/sealing the inside of the block with the special paint I have read about? I am planning to clean the block before I apply paint, but just wondering everyones opinions on...

    Does anyone by chance have a Napa part number or another parts store number for yokes that will work with a new steering u joint for a B? My original assembly is well worn, so I bought a new u joint but need the new yokes as well. I took the new u joint to my local Napa store and they were not...

    Painting B Engine Block

    My engine block for my B is coming back from the machine shop this week. Im assuming that after all the cleaning that the paint has been removed and will need a coat before being reinstalled on the tractor. In the coming years I am looking to do a professional painting of the tractor after I...

    4020 block heater element replace

    I am pretty sure that either the cord or the element has failed on my coolant tank heater. It is the JD version so going to stop by and buy a new element. I have never replaced this before, so I am wondering if there is a way to replace the element without draining the coolant? Am I ok to try...
