Watched the video before rebuilding my d902 injection pump off a rtv900 with a broke spring. Very simple but watch as he puts in the plunger (top only goes one way, but bottom has to be pointed the right direction) they need to be facing just like he shows, I didn’t the first time and it ran bad and smoked worse than with the broke spring then took it back apart and faced the bottom part of plunger just as he shows and runs like new again! (Found a rebuilt kit on ebay dealers do not have so they say) saved me 1k by watching the video vs a brand new pump.
Muy buen video. Tengo un tractor hinomoto E2304 de 3 cilindros que no me enciende, el tractor se apago por que el filtro de diesel estaba sucio con agua y ya no encendio mas y se lo reemplazo el filtro se sacó todo el aire del sistema pero aun asi no enciende y la bomba es muy similar al del video y mi pregunta es que si se desmonta de la misma forma o si tuvieras un video de como reparar la bomba inyectora de hinomoto E2304 gracias.
th-cam.com/video/RByydpUgoZ0/w-d-xo.html Thank you for watching.the above link is one of my video please watch because they are the same with the hinomoto E2304
I was watching your video and thanks for doing it. My G4200 started with a leak on the manifold for the injection pump. I replaced the gasket but still had the same leak plus picked up a leak on one of the injectors. I replaced the two "O" rings on the injector and installed another gasket. I still have the leak, it loks like it might be oil with gas coming out. The motor tries to start a little but never does run plus the leak comes out at the gasket. Is there a chance that I am pressurizing the motor due to an injection pump leak and forcing the oil-gas out? Hopefully you will have the time to assist me.
@@tractorsmarinemechanic does the engine need to be at TOP DEAD CENTER on #1 before I remove the pump? how is the pump timed to the engine? I am getting fuel in the oil and the injectors looked good diesel shop says its the pump.
Why did you adjust the fuel screw for the rack at the end? Was it out of adjustment when it came in? Or did you have to adjust it to compensate for something?
@@tractorsmarinemechanic was the idle or rpm off because you rebuilt the pump or was it a separate issue? Also I heard that once you remove the delivery valves they have to be re-timed. Is this true? If so how would you put the delivery valves back in time?
Thank you for the video! I have kubota L5740 and my fuel line going from the tank to the filter got plugged up completely. Something is in the tank that I need to remove and clean it. I used a compressor to clean the line, but the tractor still won’t start now. I removed the hard lines and no fuel is squirting out of injection pump once or ever. What could be wrong? Thanks!
@@tractorsmarinemechanic do you mean the fuel shut off valve? No, it’s working as expected. Fuel is filling the filter cup if I open the valve. I also have a mechanical pump between the filter and the injection pump. It does squirting fuel, but I’m not sure if it’s working properly or not. Fuel comes out in pulses in small amounts. Thank you
I have a kubota z402 engine, similar to the one in the video, only in 2 cylinders and it starts only when accelerated both when it's hot and when it's cold, I changed the glow plugs and the diesel filter, but it still doesn't start without being accelerated, which is problem?
Hello my freind. I have D750 kubota engine just like this. It does not have a water pump and since the thermostat is is located near the rediator more than the water jacket it will not give the exact temperature in the jacket. Im planning to install a 12 volt water pump. What is your advise plzz
8:44 that pin that slides into that other part is whats giving us trouble. It’s very very stiff to put in, but once it’s fully seated, it turns fine and has about 1/8 of end play. No rust, no burrs. No idea why it’s so stiff.
@@gerardoluebano5200 I had the same issue, I made 100% sure the sleeve was clean before sliding in the “pin” which is called a plunger.. no matter how clean I had it or what kind of lube I tried it would only go in so far and then would stick.. so what I finally ended up doing was using some 1500 grit wet sand paper and put the plunger in my cordless drill and spun it in the sand paper until it slid in and out of the sleeve like all the other ones.. I ended with 2000 grit to polish the pin out nicely so it looked like the others.. after I did this I had no issues with installing it and putting it back together. The issue I have now is my stop leaver doesn’t stop the fuel flow, i tried to make sure many times to let the rack sit into the stop leaver so I think I had it in there but no matter what I try I can’t get the fuel to slip flowing when the stop leaver is activated.. I also know my plunger is facing the correct direction with the “M30” stamp facing towards the fuel inlet so I know I don’t have the plunger in backwards. I’m stumped
@@BiffsEquipment did the stop lever (leaver) work properly before you disassembled everything? If so you created the problem. Disassemble it again and do it by the book.
Hello my friend I have a Kumiai satoh St1840 that has diesel in crankcase with the engine oil after using it ...can this be the part that has failed? My father was using tractor and then smoke white first then black came out of exhaust when he turned it of he checked the oil dipstick and found out it had mixed diesel and motor oil...
I have the same exact injection pump as the one shown in this video.. I rebuilt it exactly the same way, all my plungers are smooth, my rack moves smoothly, but the fuel stop valve does not shut the fuel off after I reinstalled it.. I have removed and reinstalled the pump 3 times to try and make sure I had the stop leaver connected to the rack but every time i reinstall the pump the stop leaver will not stop the fuel flow when I test it. I installed the plungers the same direction as the way you showed in this video and my fuel inlets are on the same sides as yours was, any idea why the stop leaver doesn’t stop the fuel flow?
be careful make sure if the fuel hole is in the right place I install my pump this way and it cause for my engine to ran away luckily I was able to shut it off the way I fix it I install the injection pump plunger the opposite way
@@aldoaguirre1244 yes I did run into this.. I first installed mine the wrong way but I realized this when I tested for fuel injection with the fuel lines disconnected first.. once I saw the fuel shut off was not working I took the pump back apart and reversed the plungers and tested it again before starting and the fuel shut off with the shut off lever so I was good. 👍🏻

@@tractorsmarinemechanic its a Shibaura S753 engine. The pump out for repairs and as yet I don't know that its leaking down the sleeves or not I just wanted to ask the question. The shut off rail was seized on full, showed signs of minute rust but I now have that working again. I am fitting new O rings tomorrow to the outlet fittings the old ones are stuffed. I did have it working for several manual pushes on each plunger but then it stopped pumping again and thats when I noticed the air coming from the O rings. As a passing point it wouldn't start, at all, but after coaxing it I did get it going but then it wouldn't shut off, I had to choke the engine at the intake, you couldn't see the yard for blue and white smoke. One injector was running at full noise it had become disconnected from the shut off rail and was jammed on full. They were miles out of singing from the same song sheet.
@@tractorsmarinemechanic it was doing that when I bought it not after I took it to bits, its still apart for a few more days as I have other work to do.
