Our Service Manager Rick walks you through how to properly bleed/prime your Kubota Diesel Engine Injection pump. Visit our web page at: www.countrysalesandservice.com
Great video, you answered some questions for me! I’m working on my Dads 1985 Kubota L345DT, I don’t know a lot about diesels. We looses one of the outlet lines trying to get to the glow plug behind it, the line leading from the high pressure pump and may have turned the base because we didn’t back it up with a second wrench. Are you saying that when the o-ring leaks it will cause the pump timing to be permanently changed requiring retiming or just that until a new o-ring is installed it won’t run right. We haven’t bled the tube leading to the injector the way you did, yet but right after we retightened and started it seemed to miss.
Thanks for the video, it was very good! I’m rebuilding an older D. 850, and tried to start it the other day. It ran what seemed well, but cylinder number one was offering a lot of smoke and cylinder number three was offering no smoke. On cylinder number one does it make sense totighten the intake valve to allow more air to enter to better balance the combustion?
Country sales very nice, I ran across my friend's kubota V1505, won't start, fuel skirt out from injection pump at # 1 and # 3 port only and non at # 2 or # 4, fuel leak out from pump shim and find out washer was installed in between shim and cover by a mechanic he hired to fix. Anyway I pulled it out but shim was badly cracked, The main question here Can I open the pump area to clean the port where fuel skirt???
Hello, I have a Kubota V1902. I understand the process of bleeding as shown, but my pump also has a ‘bleeder’ valve on the return line from the front injector. When is this bleeder used in the whole process?
I am assembling a Kubota V2403 engine and I was wondering if I have the crankshaft and main idle pulley marks in the right phase. It's the 1 dot to 1 dot marks. The rest I have correct
Replies Hello, love your work maybe you might have knowledge on a kubota mini excavator X040-4 with 1802 hrs. She fires up runs for 30-60 seconds then dies out. On the computer in the 2 fault codes pop up 064 Engine and 076 DPF is clogged. Got the DPF baked in the mean time replaced primarily and sec fuel filters cracked the lines she's getting fuse. Got the DPF back connected all the thermo sensors. Still same issue. Hooked up a diesel scanner found multiple fuel pressure sensors "high" and rail pressure issues, crankcase sensors issue. I've spoke to 3 different techs with Kubota one is say bec of DPF issues the kubota pcm/ecm shuts down after 4 attempts for safety reasons. Other tech told me "no" the bio diesel might have crystallized and I need a new common fuel rail with the sensors and new lines.
Do you do the same for l3240 the case the fuel filter goes in busted and after I replaced it I turned that button on the side to get the air out that a different video suggested after a replacement ran for about 15 seconds and it shut off have not been able to start it since I don't know much about them and don't want to mess it up even more
What is the circuit with the yellow plastic line coming out of the injector pump to the front injector body and then jumping down the line to the back injector and, I think, going to the top of the fuel tank?I’ve seen it referred to as a “fuel return” which doesn’t make sense. Also as a “vacuum line” - not on a diesel. On my 1981 L345 that line starts at the fuel line going to the pump, goes through an “air bleed” valve, jumps to all injectors, and ends up connecting to the top of the fuel tank. None of this is in my manual or parts book.
My Kubota RTV 1120 D will not run but it will run a short amount of time after manually pumping fuel into the injector pump. Can this possibly be a bad fuel selonoid?
Hi and thank you for the video ! I have kubota l5740 hst and the fuel line going from the tank to the filter got completely clogged. I cleaned the line using a compressor, but the tractor still won’t start. I loosened the top nuts on the injection pump and no fuel is coming out of any outlets when I try to crank it. I do have a mechanical pump before the injection pump. I tried cranking up with outlet line removed and it’s seems to me barely squirting fuel. Is the pump bad now? Thanks!
I would check and replace all fuels filter (may have a spin on & inline). Then I would try to identify what cause the fuel restriction. If it is grass, dirt, debris, etc. you would want to check the tank and make sure the screen in the tank is still present and make sure that when fueling there is not debris anywhere near the inlet when fueling. When blowing out lines to the tank it has a tendency to blow off the screen in the tank. If it is black/green it would be "algae" which would require you to treat with a biocide to prevent continued growth. "Algae" requires a higher water content to flourish in fuel, so you may want to check your fuel source for signs of water. It could be possible that the pump could have been damage prior to it being clogged as it it is a fuel lubricated pump with a very tight tolerance. If you need any further help feel free to reach out to us.
@@CountrySalesService thanks for the response. After all It was a mechanical pump causing issues. After I replaced it, the tractor started right away. I did pull the tank out and washed it. No screen has come out, except some gooey stuff.
Thank you for this video. I have performed this procedure on a kubota D1005 and still will not start. It’s getting proper air and the motor has good compression. I have pulled each glow plug and tested them and they are working properly and getting power when in the correct key position. Fuel leaves the barrels on all cylinders like yours did in the video. When I crack the lines up top and crank the engine the fuel comes out with bubbles for a bit then stops at which point I tighten the lines up. Unit does not smoke when attempting to start. What would cause this? Thank you
Hello Kevin, Based on the information provided, I would guess one of a few things. The lack of smoke indicates that the engine is not getting fuel. This is can be caused by low compression (you stated it was good, what was the PSI you measured?). Since you indicated fuel is moving from the pump I would question the injectors. If you have not replaced them I would have them tested. Secondarily, though you may be getting fuel to the injection pump, you many not be getting the correct volume/pressure to the pump. If you have a manual lift pump I would inspect it to make sure it does not have a pinhole in the diaphragm (usually noticed if engine loses prime over a couple of days). Again, these are quick checks, I would need a little more history on the engine/machine to get a more pinpointed trouble shooting. If you need help, please feel free to contact us at 330-683-2500 and we can help you out!
My 4350 had a rat eat through low pressure line, I replaced it with a transparent yellow fuel line and it ran. As it got warmer it ran less well and I could see little air bubbles in the transparent tube. I live a distance from the dealer and would like to fix without breaking the bank. Any advice would be great.
@@scottheller1379 Hey Scott, Based on what you are telling me it is pulling air. It typically comes from one of a few places. First, you should have a have a manual lift pump. If it has a pinhole in the diaphragm you can get air entering the system. This is usually seen when the engine is recently run it starts right up, but if it sits for a while it takes longer to start as the pump is causing the fuel system to lose prime. Second, inspect the fuel filter/ fuel filter base and make sure that it is properly seated, no damage, nicked gasket, etc. Finally, if the delivery valve holders of the injection pump were turned or the O-rings have "dried out" you can get air in the system as well. Feel free to contact us if you have any other questions.
@@CountrySalesService thankyou so much. Am going to get a mobile mechanic out to help. Would let you guys but pretty sure the travel cost would be prohibitive lol. Again, thank you for your wisdom.
hi guys, i have a 4 cylinder kubota engine we tried to swap the pumps and could respect the allignement marks noe the forklift cant start any tips PLEEEEEEASE ?
What is the procedure for putting these barrels back to the correct timing? I want to install new plungers and have to remove the barrels to do so.. Would each barrel have to be re-timed once taken apart because everyone I watched rebuild these pumps just snugs them down with a wrench and throws the pump back into the engine
Our injection shop uses a diesel fuel injection test stand to ensure each pump meets specifications for fuel output and fuel metering. If you replace the plungers the barrels would need to be "re-timed" to ensure they are back to spec. It is possible to get lucky and snug them down and still be in spec, but there is no procedure to do so.
I work for Operation Blessing Disaster relief. We have 2 mobile kitchens with 12K Onan Diesel generators, with 3 cylinder Kabota engines. One has 8,000 hrs. mfg. 2008 and the other has about 6,000 hrs. mfg. 2013. Both have the same symptoms. With no load, they run for about 20-30 hours, then shut down. With a load, they may run 15 minutes to 4 hours. We have spent thousands of dollars on repairs to no avail. Any suggestions?
I am having trouble getting a Kubota 2403 started. I was checking the injection pump like in your video but a soon as i turn the key and the electronic fuel pump starts, fuel comes out of the injector pump. Is that normal?
D1105 Kubota: I ran this test and 2 of the 3 barrels are spitting fuel, the 3rd has some fuel just resting in the top and maybe very slowly flowing out when cranking the motor but for sure not spitting like the other 2. Can that be fixed or is the pump shot?

Hi, my 743 B Bobcat with a Kubota V1702 was hard starting. I purchased the correct glow plugs, thinking, at 30 years, It wouldn't hurt to replace them. I knew to hold the bottom nut on the pump side, when loosening the fuel lines to the injectors, and didn't turn any of them. After reassembly, the first pump is leaking, and I am unable to get it started. All the loose fuel lines at the injectors showed fuel leakage betore I tightened them. The first time I tried starting it I got white smoke for just a few seconds, now just black, but it won't keep running, and it isn't hitting on all cylinders. Does the pump have to be removed to fix leak? Why won't it stay running? Thanks
It sounds like you have a delivery valve that may be out of adjustment or the O-rings need to be replaced. With the barrel out of adjustment you will be getting more or less fuel (running rich or lean depending on the direction it was turned). You can try and snug down that barrel and see if you can get it to seal. If not the pump would need to be removed and repaired.
Hello, may You make video about bleeding on Kubota z482 engine? Have recently bought Avant miniloader and it stopps after 15-20 minutes of work, and its cold weather now, may the problem be in air? Does it help to pump fuel pump with hand then?
The process for bleeding a Kubota Z482 is the exact same process as shown, just a few less cylinders. If the engine runs for 15-20 minutes and starts to cut out I would check 2 things; First if you have a manual lift pump on the engine, I would cap it off and bypass it with an electric lift pump. This would verify if it was (could be) a fuel supply issue. Secondly, if the engine cuts out, but you can immediately restart it, I would take a look at your stop solenoid. If you need any further help please give us a call.
At the 4:00 minute mark you show how to put a wrench on the bottom hex nut to keep it from turning. So, mine turned and now I have black smoke pouring out of the exhaust and the engine will not shut off. I have to pinch the fuel line to get it to shut off, turning off the valve on the water separator does nothing the shut the engine off with. I have a 3 cylinder kubota D1502 engine. I would appreicate any advice you could give me.
It sounds like the barrel is now out of adjustment, so when the pump is put into the "off" position it continues to pass fuel. It this is the case, just send it in to us and it is a quick simple fix, can get it back to you in a day or two.
@@CountrySalesService Thanks for this, I was out there today and moved the nut a few notches and that cylinder fire up with no issues (smoke) I locked it down there but if I still have probems I will be contacting you for service.
I have a M5030 it runsgood up to about 3/4 throttle then it acts like it is starving for fuel I replaced the fuel filter it got better but still does it. Any ideas?
Hello, I would verify that you are getting the correct volume of fuel to the injection pump, should be between 5-8 PSI to fully supply the injection pump. If it is, then there is an issue with the injection pump. It could be a variety of reasons, it would be easiest to have it inspected and tested.
Hlo, am faisal working in soudi Arabia, could you please send me valve lash adjustment for Kubota V2403 model engine. Do you have any vedeo related about this pls suggest for me. Thanks
It is usually one of 4 things; if you have a manual lift pump there is most likely a pin hole in the diaphragm, the housing of the injection pump is cracked, you have a leaking injector(s) or a barrel is damaged in the injection pump.

hi,im having the same trouble on my nanni 5250 with the bosch k series mini pump, i suspect the fuel feed pump at fault and have changed it with an electric one and i can only get fuel in drips from the injectors no matter what i do ?.
@@CountrySalesService many thanks for the reply, i strongly suspect the fuel rack, as i can only move the throttle lever a fraction that it used to move, hope you are well.
Older Kubota B2650 Diesel ◘ I use Glow Plugs on warm-days-start thinking they are long-service-life anyway ○ Are these only used for starting? ( Cold or otherwise ) I thought glow plugs ran constantly but apparently I need to be corrected on this; Both of us are accomplished Mechs's ~ Kubota B2650 is giving very good service;
Glow Plugs are for cold weather starting, and aren't needed once the engine is capable of staying running. I work on Diesel's in -40 temps and a kubota is one of the best engines to get running.
@@RealSprooseMoose After posting my findings are "Starting assist" not what I thought ~ very moderate conditions so your advice is that if I keep battery charged and it will "catch" ( begin operation ) to ignore carbon cloud and other things and not use them at 40° F - correct?
Replies Hello, love your work maybe you might have knowledge on a kubota mini excavator X040-4 with 1802 hrs. She fires up runs for 30-60 seconds then dies out. On the computer in the 2 fault codes pop up 064 Engine and 076 DPF is clogged. Got the DPF baked in the mean time replaced primarily and sec fuel filters cracked the lines she's getting fuse. Got the DPF back connected all the thermo sensors. Still same issue. Hooked up a diesel scanner found multiple fuel pressure sensors "high" and rail pressure issues, crankcase sensors issue. I've spoke to 3 different techs with Kubota one is say bec of DPF issues the kubota pcm/ecm shuts down after 4 attempts for safety reasons. Other tech told me "no" the bio diesel might have crystallized and I need a new common fuel rail with the sensors and new lines.
So a couple of things on this, if bio diesel was used I would guess the injectors are bad. Maybe even pump and rail. But before I could diagnose it I would need to see what the actual (p) codes that are in the ECU. That would tell me if its fuel or electrical.
Thank you for replying I was able to replace the thermo senors and got the dpf resolved. I still have the code “64 Engine system” code once I plug in the diesel laptop the code high rail pressure is still up. I order new fuel filters both primary and secondary the clear one. I am going to drain the whole tank. Then add 911 diesel. The customer stated he did use bio diesel and this mini ex has been sitting for 3 months. So that would be an issue. I’m still holding off on the fuel injectors thank you again!

How much fuel pressure should I have from the fuel pump ?
If you are referring to the lift pump (supplies fuel to the injection pump), it should be between 5-7 7 lb/in²
HI GOOD VID, DO YOU HAVE ANYTHING ON 455 J/D 3TNA72UJ3,REGARDING THE INJECTOR PUMP BLEED/R&R INJECTORS SERVICE.
We don't currently have a video for that, but will put it on the list!
Hope you can help me with that to buy my parts, i will appreciate it
I get a clicking noise sounds like a short when i turn the key on. I think i have an air lock. Tc 25d new holland
The clicking noise should be your fuel shut off solenoid turning on and off. That will make an electrical clicking sound
Hlo, am faisal working in soudi Arabia, could you please send me valve lash adjustment for Kubota V2403 model engine. Do you have any vedeo related about this pls suggest for me. Thanks
The valve lash for that engine is 0.18mm to 0.22mm, intake & exhaust, cold only.
Bos...diesel and engine oil mixing... what pblm?
It is usually one of 4 things; if you have a manual lift pump there is most likely a pin hole in the diaphragm, the housing of the injection pump is cracked, you have a leaking injector(s) or a barrel is damaged in the injection pump.
Hey guys, i have an engine like that one on video, I think transfer pump is bad but I don't have the manual neither the serial and model number, it lownmow machine is 4600
please How to calibrate Kubota fuel pump.? Thankyou.
it has to be done on a test stand. You can send it to us and we can fit it for you.
@@CountrySalesService Hello . I have a problem with the engine rpm speed. When I start the engine rpm going high and I can't bring them back
What could be the reason for this ?
GOOD JOB! BUT FUEL AIR BLEED COULD HAVE PERFORMED BY LOOSEN HP LINES ONLY AT INJECTOR INPUT ADAPTER INSTEAD REMOVAL COMPLETE SET OF HP LINES.
i believe he was demonstrating as if installing a new/rebuilt pump, best to verify it pumps & shuts off before installing the lines
Thanks!
hi,im having the same trouble on my nanni 5250 with the bosch k series mini pump, i suspect the fuel feed pump at fault and have changed it with an electric one and i can only get fuel in drips from the injectors no matter what i do ?.
could be a bad start solenoid if it has one or the fuel rack is stuck in the injection pump
@@CountrySalesService many thanks for the reply, i strongly suspect the fuel rack, as i can only move the throttle lever a fraction that it used to move, hope you are well.
Start it! You didn't prove that they are bled. I wanted to see if I would run to see how long it cranks to fire.
What? No money shot???

Older Kubota B2650 Diesel ◘ I use Glow Plugs on warm-days-start thinking they are long-service-life anyway ○ Are these only used for starting? ( Cold or otherwise ) I thought glow plugs ran constantly but apparently I need to be corrected on this; Both of us are accomplished Mechs's ~ Kubota B2650 is giving very good service;
Glow Plugs are for cold weather starting, and aren't needed once the engine is capable of staying running. I work on Diesel's in -40 temps and a kubota is one of the best engines to get running.

After posting my findings are "Starting assist" not what I thought ~ very moderate conditions so your advice is that if I keep battery charged and it will "catch" ( begin operation ) to ignore carbon cloud and other things and not use them at 40° F - correct?

Hello, love your work maybe you might have
knowledge on a kubota mini excavator
X040-4 with 1802 hrs. She fires up runs for
30-60 seconds then dies out. On the
computer in the 2 fault codes pop up 064
Engine and 076 DPF is clogged. Got the DPF
baked in the mean time replaced primarily
and sec fuel filters cracked the lines she's
getting fuse. Got the DPF back connected all
the thermo sensors. Still same issue. Hooked
up a diesel scanner found multiple fuel
pressure sensors "high" and rail pressure
issues, crankcase sensors issue. I've spoke to
3 different techs with Kubota one is say bec
of DPF issues the kubota pcm/ecm shuts
down after 4 attempts for safety reasons.
Other tech told me "no" the bio diesel might
have crystallized and I need a new common
fuel rail with the sensors and new lines.
So a couple of things on this, if bio diesel was used I would guess the injectors are bad. Maybe even pump and rail. But before I could diagnose it I would need to see what the actual (p) codes that are in the ECU. That would tell me if its fuel or electrical.
Thank you for replying I was able to replace the thermo senors and got the dpf resolved.
I still have the code “64 Engine system” code once I plug in the diesel laptop the code high rail pressure is still up. I order new fuel filters both primary and secondary the clear one. I am going to drain the whole tank. Then add 911 diesel. The customer stated he did use bio diesel and this mini ex has been sitting for 3 months. So that would be an issue.
I’m still holding off on the fuel injectors thank you again!
