    Water in sediment bowl

    There's more humidity now days than when you were young. Seriously, the ethanol in the gasoline does bind with water very easily, even humidity in the air.

    Spray in transmission

    When looking in the access hole at the back of the tractor, the leak is on the far left side from the top. There is no drip or spray in the center or the right, at least that I can see. It is a steady drip from the top, not quite a stream. No spray. Any idea what Is there a way to fix this...

    Transmission Fluid Level

    Also, for what it's worth......this tractor was recently split and has a new clutch. My mechanic and I replaced the clutch and seal. My ignorance will show again.....what is a clutch pack? We didn't do anything to the transmission. It's possible there is a leak in the low pressure system...

    Transmission Fluid Level

    The large steel lines underneath are indeed old and have had issues in the past.....someone brazed a few spots. I was going to replace them but the JD dealer told me they were not available. If one of these was leaking, would it suck air into the system? Or would I see a spray when the...

    Transmission Fluid Level

    I changed that transmission screen not long ago......just a few hours of operation ago, actually. It was very clean.....it didn't really even need changing, but since I had a new one, I installed it anyway. What I didn't change was the small screen on the hydraulic pump in the front. Could...

    Hydraulic question

    Well, I say it didn't put a restriction on the engine.....I didn't notice one. I'll have to check when I get back out there.

    Hydraulic question

    The cylinders will hold position when the valve is in neutral. No problem there at all. The control valve feels OK, and I didn't notice any obvious restrictions in travel of the handle. The engine does not change speeds hardly at all when the hydraulics are activated. It does not seem to be...

    Hydraulic question

    The system won't let me PM you and I don't see your email. I'm glad for any advice...let me know how to contact you. You can email me at sanbog [at} embarqmail dot com. Here's what I know: It's an old tractor, and my engine quit, so we were rebuilding the engine on weekends. It took us a...

    Hydraulic question

    I'm having trouble with my hydraulics on my JD 2640 tractor. I had it laid up for a while working on the engine. I finally got the engine working great, but now I have a hydraulic issue. The 3-point goes up and down fine. The front end loader forks go up and down fine....it goes down a tad...

    Replacing injector

    I have a JD 2640, 4 cyl. 276 diesel. We did a lot of work on it, including replacing the pencil-style injectors. According to the JD parts book the new injectors are supposed to have a washer and a seal ring on the bottom, going into the head. The seal has exactly the same outside diameter...

    Adjust injector pump?

    So would it be a proper load if I just hooked up the brush hog and did some mowing?

    Adjust injector pump?

    We did not test the injectors, but replaced them all. They are all brand new.

    Adjust injector pump?

    Sorry, the cam followers were returned to the same same cam lobes, the the cam was NOT reground or machined.

    Adjust injector pump?

    So far, we have run this engine for a little over two hours after the rebuild. We ran it at about 1200 rpm for a very few minutes, then spent the next two-plus hours at 1500 to 1700 rpm, partly just driving around or and partly idling. Occasionally we'd rev it to 1900 or drop to 1200 for a few...

    Adjust injector pump?

    We just rebuilt the 276 diesel engine on my 2640 tractor. We were very careful with everything and replaced anything that appeared to need replacing. We did not do anything with the injector pump other than to make sure it was installed correctly. We just started the engine after a...

    Gator Carburetor Question

    I admit ignorance of the subject. I have not kept up with any ethanol issues, so it's entirely possible. All I know is that I've left gas in my Briggs & Stratton lawnmower every winter, and left gas in the gas can all winter, every year. My current mower is 10 years old and every spring it's...

    Gator Carburetor Question

    I acquired an old gator.......it's 16 to 18 years old, about 1250 hours on the meter, which I think is legit, since I'm good friends with the owner. It won't start, and I took it to the local JD dealer. I have had two conversations with two separate service men from this dealer, both of which...

    Reconnecting Engine

    Concerning the problem above, here is what we have done: --Before tyring to fit the engine, we test fit the new plates on the splines. They slide on easily and perfectly. --Roated the engine, several times, attempting refit each time. --The dowel pins are not yet engaged, so they are not...

    Reconnecting Engine

    OK, so my JD 2640 tractor with the 276 4-cyl engine needed rebuilding. So we split the tractor. While we were splitting it, it was very difficult to separate the engine from the back half of the tractor.......it came apart, but it was quite difficult to get it apart. We finally did, and rebuilt...
