jeepwm69 7,751 Posted June 10, 2022 @Fishfiles @_Wilson_™ The old 2640 quit on me today. Was bush hogging and it acted like it was bogging down, so I chose a lower gear, but it continued to slow rpms and the throttle didn’t have any effect. It will start up but quickly dies. I’m hoping it’s the fuel filter. Any other ideas? IMG_0461.MOV 1 Share this post Link to post Share on other sites

Goober 1,555 Posted June 10, 2022 Can you check fuel flow at the carb or filter? It sounds like it’s only running for 1-2 seconds. A clogged filter maybe. Perhaps a chunk of debris in the carb bowl Share this post Link to post Share on other sites

I had an extra on the shelf and bolted it on and it worked great. Headed to deere now to get a filter. I’m sure it will be cheap lol Share this post Link to post Share on other sites
jeepwm69 7,751 Posted June 10, 2022 Well color me shocked. Filter was 17 bucks. I figured it would be 2 to 3 times that much in a John Deere box Share this post Link to post Share on other sites
ATC4ever 1,090 Posted June 10, 2022 Youve changed those filters a few times before i assume? Sounds like if its not the filter, maybe the fuel pressure isnt there. Good ole diesels needing high pressure. 🤔 Share this post Link to post Share on other sites

_Wilson_™ 6,593 Posted June 10, 2022 (edited) 12 years ?! wow! our get changed every year sometimes twice a month depending on what the water seperator looks like...... now so,e models have metal canister filters that look like a oil filter, but these became the standard in a number of models....... the transparent glass helps you keep a check on the sediment level, but most big horse power units have one that a water separator, the a fuel fi....... but back then fuel was transferred so many times..... a man couldn't keep sediment down,...... so big nurse tanks had a fill rite setup like this (combo fuel, and water bowl. i Edited June 10, 2022 by _Wilson_™ 2 Share this post Link to post Share on other sites

That's what the one on this tractor looks like. Square glass filter. I probably only run this tractor for about 10 hours/year, so not a lot of hours on it, but if I need to be changing it more often I will. I did change out the hydraulic fluid last year (with your help) and last week I changed the oil, blew out the air filters, and greased it. 1 Share this post Link to post Share on other sites

_Wilson_™ 6,593 Posted June 10, 2022 just a twist here...... I've been away some of you know why...... i would just like to sorry i apologize....and for now i would just like to keep working on my new healthy diet, so those of you who don't dont know, plz don't ask my me,,or bother administration ..... as i will let this cat out of the bag myself, i do ask that y'all keep in your thoughts and prayers, now back to the subject at hand, pardon me jeep, but it's about time i spoke of this, because i HAVE been dragging my feet.....

shadetree 5,977 Posted June 10, 2022 Diesels do not require spark or in this case..gasoline as you can guess. they run from a high compression only, if the compression is low ?, they will not run. never..ever..let a diesel engine run out of fuel ?..once they run dry ?, you get air in the line, and it is a royal pain in the back side to get them bled !..lol. 1 Share this post Link to post Share on other sites

Well it fires up for a few seconds, then dies. I was rolling along bushogging some pretty heavy stuff, and it started bogging so I went to a lower gear. Then I noticed that the throttle wasn't holding the RPM's up even with the clutch engaged, and here we are. Share this post Link to post Share on other sites

Fishfiles 20,147 Posted June 10, 2022 Find the bleed screw on the side of the injection pump , open it , you mentioned your lift pump has a lever , pump that lever on the fuel lift pump and see if you can get fuel to come out the bleeder on the injection pump , if so then close the bleeder and pump some more , you can try to start and if it don't you might need to bleed the injectors --- how bad was the filter ? did it have water in it ? take a pic of the top of your injection pump and post ---- is there a wire going in the top of the injection pump ? if so , it would be the run /kill wire , does it have voltage to that wire with the key on / 1 Share this post Link to post Share on other sites

It looks like a common problem is for the plastic flex ring to come apart and stop everything up with bits of plastic. https://www.yesterdaystractors.com/cgi-bin/viewit.cgi?bd=ttalk&th=1297006 I haven't gotten out there yet. Still at my day job for a bit. Am going to run out there after work with the new filter and see if that helps. I'll take some pics of the injector pump if the new filter doesn't get it going,and post them up. Share this post Link to post Share on other sites
Fishfiles 20,147 Posted June 10, 2022 I thought from reading back that you already changed the filter and there was a problem I would guess from the square fuel filter , that is an early 1970 to maybe 1980 tractor engine , so I am going to guess it has and electric run / kill solenoid , that is similar to this video https://www.bing.com/videos/search?q=john+deere+stanadyne+fuel+shut+off+solenoid&view=detail&mid=D7E9E6B52E7E5B69EB3ED7E9E6B52E7E5B69EB3E&FORM=VIRE Share this post Link to post Share on other sites

Fishfiles 20,147 Posted June 10, 2022 after you get it primed , if you spin it over , after you loosen the tube flare nuts on the back of the injection pump , it will tell you if there is fuel being pumped --------- the magnets in top the injection pumps are notorious for going out , an easy change , the newer models use tamper proof screws and don't sell the magnet / solenoids separately , they want you to spend money , but the solenoids can be ( use to be able ) to be purchased you may have to bleed the injectors , probably not if you got a good battery , unless it sucked a slug of water / trash , then you might have to bleed / purge it a bit can you tell it's past 5 o'clock somewhere ^^^ Share this post Link to post Share on other sites
jeepwm69 7,751 Posted June 11, 2022 Sooo, old fuel filter wasn’t even glass. Fuel that came out looked good. No change. Here’s the pump. Smaller than I expected it to be looking at pics. Had the mini me with me so didn’t do more today. Where’s the bleeder on this thing (screwdriver?) and anything else I can try, or do you think it’s that plastic bit coming apart? I was surprised that there was one nipple for the top hole for the filter to slide onto, but not for the bottom two ports Share this post Link to post Share on other sites
