Kubota 3 cylinder diesel Zexel injection pump rebuild Part 2

- I purchased a former Air Force Light plant, that had a 3 cylinder Kubota diesel in it. The injection pump was locked up, and would not allow fuel to flow to the injectors. In part 1, I got the pump apart. Now it is time to clean it and put it back together!
Follow along with me as I disassemble and figure out what the problem is, and fix it!

These two part videos were a life saver for me! I first came across the uncommented one as you did and was so pleased to find this one!!! Thanks a ton man
I just rebuilt mine today, this part was a lifesaver!! Thank You So Much!!
Thank you sir. You took the magic out of this pump for me
Very interesting. It's exactly what i need for my Kubota.
Thank you very much from France !
Glad it was helpful!
Great video. I had the same issues. This video helped me resolve my issues. I wish I had seen this video before I lost 2 of those BLASTED little pins!!!!!!!!!!!!!!!!!!
Parabéns pelo vídeo. Realmente ele ajuda muito , vc poderia fazer vídeo da BB injetora da Mew holad l170 ou cat 226b
BEST VIDEO ON REBUILDING INJECTOR VALES!!!😇
Glad it helped
Some tricks of the trade. Instead of fighting all those little pins and Detents, Put a gaba Vaseline on them. It will hold them in place. And the Vaseline has such a low melting point It will turn to liquid with any amount of heat or fuel Hits it.
Was very helpful need to make real clear how the pump pin faces had to watch that part several times.one of my three wasn’t pumping out any diesel.my starter was weak.would only crank about ten turns and it would crow bar the battery down to nothing.tried a new battery same thing.put a new starter on and man did she spin then.180 for a battery 381 for a starter.came close to just buying a new 72 incher
Is that what happens if the piston faces the wrong direction, no fuel? I started my D902 and it went run-away, but lucky for me, I had a shutoff in the fuel line.. smoke everywhere and crazy rpm. I am not sure the cause... maybe the slider pin did not engage the shutoff solenoid slot?
Your video set on the zexel Kubota D950 fuel injector pump was delightful.
Have no seen or read about the plungers' physical size and stroke length.
Understand it may be 5mm diameter but 5.5 mm diameters are also mentioned.
You were very fortunate to get the light generator manual which was so detailed.
Zexel does not recognize the Kubota serial numbers so not sure how to find tge actual Zexel pump serial number and alternat plunger id part numbers.
Any comment from you would help.
Thank you! I'm glad it helped.
Unfortunately the only parts I've been able to find for these pumps are the o-rings. I have not been able to find anybody that will sell any internal components. I have found the entire pump for sale that's it.
Do you have a link to the injector pump manual
Please explain calibration the pump you assembled.(kubota). please.
Thank you - excellent.
At @25:10 you said the slot faces to the back, opposite the slider shutoff and the 'Z' faces forward to the slider. Another person's video says the opposite?
Can’t see everything because you keep moving out of view. Need a wider range of view
Can the twin o-rings be replaced without taking the pump that far apart? My shibaura runs great, just leaks fuel. Hoping to replace them with the pump still on the tractor…. Edit: on a late 90’s shibaura in a NH1530 I was able to pull apart for orings while on the tractor, and my pins are staked so they don’t fall out. Worst part will be getting the ‘piston’/ rod? lined back up while reinstalling the delivery valve cause the housing is on an angle allowing the piston/ rod to lean. I managed one so far, might jack one side of the tractor up. Never been so careful in my life. I’ll update when I succeed or screw it up. Thanks for replying and the video.
Unfortunately I believe you have to take the pump apart to pull the barrel out to replace the O rings
Update: success! O-rings from the dealer were $50 for the six I needed. I cheaped out and got hyd orings from Napa for $2. I believe the lower oring seals fuel from the crankcase, so I will make sure I’m not making oil. So on a NH1530 shibaura zexel it can be done on the tractor. Just be very careful and clean, and mark the location of the valves cause that will affect fuel delivery
Thank you!I am going to follow your videos to rebuild an injection pump for a Mitsubishi L3E which looks similar. Did you end up changind the o-rings or you just used the old ones?
I'm confused is the m 30 towards the crankshaft side or outside of engine. I lost all 3 of my pins and had to make some from drill bits cut off. Great video
Which part is the m 30? I did this 2 years ago so forgive me for not remembering. Be glad to help if I can.
@@steamman5320 the part # on the plunger
@@rayhuggart5214 outside I seem to remember.
@@steamman5320 OK, this was also my question. But now you won't remember for sure. lol
How do I get the parts listing for a parts list for 15841-51010 zexel injection pump? I need the two "O" rings .
good night, I'm talking about Brazil, you have engine references. kubota D1005.if you have it I would like to know the height of the piston in relation to the face of the block.(piston projection) and torque values of the head screws.I'm very grateful if you can answer me.ok.
Did it work?
Yes, there is a part three with the light plant running.
Good day sir can I have that manual diagram
Hello Where do I pick up purchase a manual for D722-E ? Thank you
Where can I find internal parts?
Hey just following up. Did you ever test the pump? And if so how did it work out?
Yes, worked great! Check out part 3!
@@steamman5320 great! My parts arrive tomorrow and I will be rebuilding mine. Did The numbered discs or the upper torx plate location have anything to do with timing or did you just put it back the way you removed them?
@@anyandalldiy6704 the spacers are for timing so make sure to note where and how many, and I just rotated the heads back to where the paint came off and it seems to be perfectly fine.
Hello. Most all videos on this pump seem to be blocked "including this one" any idea why? I've seen it many times on other subjects but this one is a need to know jobby.
What do you mean by blocked? What country are you in?
@@steamman5320 thankyou for your quickness. I'm in france
@@tomthomasjohnpaulmooremawr3014 no problem! It could be something to do with your country. I have the videos set to open, maybe try using a VPN to watch it from another countries internet?
@@steamman5320 , ok i may try that anouther day thankyou.
Sir, can you give me a reference number for the zexel injector pump? I've got a kubota bx23 engine, and I don't see an ID number for the pump. Also, can you give me a part number for the replacement part kit? Thank you, Arthur.
I believe the ID number is on the front edge? I know, 2 years too late. LOL
Nem az asztalon dolgozol ezért nem látszik mit csinálsz!
Can't see what you are doing
you left one of your pins out
Did it work
It did, very well! Look for part 3 for the completion.
Parabéns pelo vídeo , vc teria como ensinar a regular a do motor perkis shibaura terex ou cat 226b sou do Brasil Goiânia
