Thanks just the information i was looking for. I soaked a seized denso pump for three days in a heated ultra sonic cleaner. Finally got everything freed up enough to tear down. Got back to assembling everything and forgot which way the plunger went into the barrel! Its off a older Mitsubishi k3a engine. So my parts are a little different but i get the idea. Mine also has a mechanical cold start fast idle feature.
Very helpful but in the bottom of my rollers I have two 95 shims and a 10 shim does it matter which way they go or what part of the pump they go in like a visit 1 2 or 3
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.
Hi, thanks for detailed video. I had Cummins onan 7500 with kubota 3 cylinder engine. The gen was a few years working with no major issues until now that get high rev all the times and I had not find the way to restore normal RPMs for work. When I started it go to full acceleration and I had to cut the fuel for turn off. Could be the rack governor loose in any way and stuck in high RPM? Any advice? Thanks.
Is it possible to replace the barrel holder o rings with the pump housing still in the machine or does the pump assy have to come out and be done on the bench, thank you.
The vertical slot on the plunger. I have a zexel that is similar, do you mean that the vertical slot goes opposite of the fuel inlet? Essentially opposite of the slide.
I have a 4 cylinder perkins with a similar injection pump. I'm getting fuel in the oil. I've changed the fuel shut off solenoid, all the injectors and have had no luck. It doesn't have an ounce of blow by so I don't think its a cracked/hole in a piston. My last shot at trouble shooting is the O-rings on the outside of the barrel port that mates with the injection pump case. Do you think that a broken O-ring could be the cause of fuel in the oil? Thanks
I have the same thing already with two the same pumps 4 cyl, think it is a common issue for this pumps, i changed the orings but still its leaking on top and in the motorhouse. I did not find a solution and bought an other pump
I need to replace the two o-rings on the barrel/plunger housing. Squirting fuel. Can I do this with the pump still installed in the machine? I can’t tell if that roller lifter in the bottom of the pump is attached to the barrel housing.
Thank you for the video. Could I ask a question please? In which direction would you turn the delivery valve housing to obtain more fuel, clockwise or anti-clockwise? Thanks for your explanation. Very thorough! All the best!
I know this is late but do you know how to turn this pump up or can it done .also what about injection timing on this pump. Not a whole lot out there on this pump.
I have a video listed on spill tube timing. If you want more fuel you can remove the screw that limits rack travel on the block. The other thing is turning the barrel holders cc but the pump will need to be calibrated after doing that.
@@danielboyd9507 one should be just under the injection pump bottom bolts that hold the pump in. It’s been a while but next to the fuel solenoid some models may have limited rack travel there too.

Very helpful, thanks! Please post more about this injection pump.
Thank's for your video very helpful to me!
I'm needing to find a manual for a Isuzu 3ld1 engine with 3 Zexel pumps. Removal and installation.

Where do you buy your parts for these pumps?

where do you get the new o rings?
Where can i get the alignment pins missing 2 of them?

Did u ever figure the oring replacement out thanks

Does,that pump need oil in it?
Good video Same zexel 44060? I am nedd repair rebuild kit?

yes but be carefull
Where can you find parts for a 104205-3071 kubota injection fuel pump. 6:35 6:40
Thank you for the video. Could I ask a question please? In which direction would you turn the delivery valve housing to obtain more fuel, clockwise or anti-clockwise? Thanks for your explanation. Very thorough! All the best!
Counter clockwise
@@Plowboydually Great, thank you! Love the tractors! Mental!
@@Plowboydually can you do this by yourself? tryna get the most fuel for a d600 with 5.5's and cut dv's
Great videos, can the fuel leak down the crankcase and mix with engine oil, if so what causes it and how to repair , cheers
Yes. The barrel holders have o rings top and bottom that seal against the pump body.
Can the barrel holders be removed to replace the o rings without having to remove the whole pump and dismantle it
@@shalensharma636 it will need disassembled.
Thanks

Thanks information. There is not a lot out there that I can find on this pump. Thanks again .
Would that be the screw with the tamper resistant cap on end of for block on front of engine

Thanks for the reply. Just now saw it. Thanks for your time. Very helpful
