Ive always been told these need to be taken apart in a sealed environment, like zero dust or grease. Obviously, that isnt the case lol. Good to see, these Kubota engines and their pumps are damn near indestructible.
they are smooth i had to use a wire wheel to clean all the parts they were stuck together really bad tarnis and rust i might of reined the pumps tolerances
Hi, thanks for detailed video. I have this engine in a onan cummin generator and 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.
Great video thankyou. I've rebuilt my pump and each port shoots out fuel as expected but it doesn't appear to get enough pressure to pop the injectors. The injectors work find on another machine. Any ideas ?
I admit that I learned a lot from this video. Congratulations on the mastery and skills, but I don't like the messy workplace and the mixing of the elements of the pump sections. I wish to see a level up next time.
Nearly identical looking in my d1703 kubota engine, I've heard that you can upgrade components for more power in these but I don't know where to start . Do you know of any sources for power adders?
Hi, I gotta a question for you, friend. Those d1105 engines come in a turbo variant, is it an easy upgrade to take a 24 hp regular and turbo charge it to that sweet sweet 33 hp by any chance? What would I need to safely turbo it?
I got D722-E Kabota the pump will bleed out of the bleeder valve not out of the injector . I tried running it last night . I’m hoping the fuel soak to the parts . Let it start working again. Motor be sitting for about 1 year . If not look like I’ll take to take it apart clean it . Thank for the video. ? What if I take the injector lines off . Try spraying cleaner or wd40 Will that help Will the loosen up the parts ? Before attempting . Taking it apart .
Are you sure that the plunger should not be in the opposite side (M30 not facing the plunger rack)? If I follow you, the fuel delivery valve is not shutting off when the rack is at off position. Thanks
@@tractorsmarinemechanic isnt this a 16032 pump? im pretty sure that benjamin is right,,no matter what engine this pump sits on it works the same,,this zexel/Bosch pump sits on many diffrent engines,not just kubota,,like kia cars and iveco for example.i realy whant to know if u put that plunger the wrong way cus im rebuilding one myself and all info i could find but yours say the other way around,,,M30 at the back(slots in the plunger on the backside were the hole is in the cylinder.)
Hola saludos desde México, agradezco mucho la aportación de tus videos, sirven a muchos de nosotros, un favor podrías apoyar subiendo un vídeo de como calibrar las punterías del motor Kubota modelo CT3-44TV (D722) este motor lo traen equipos para refrigeración marca Carrier, agradezco de antemano tu atención y ojalá tengas una aplicación de transductor de idiomas, sigue con este buen trabajo tu servidor Sr. Cristalinas.
Please ,I am not argue with you, phasing May not be there.but calibration certainly is there, please see, ovel Shep grove is there,on the barrel holder.
Ok. The plunger barrel and the plunger there is a timing mark.if your plunger is already installed remove delivery valve HOLDER and also the DELIVERY VALVE .if you facing the control rack pump cuts from the plunger must be on the left side.just follow the timing mark at the control SLEEVE and PLUNGER.
I have the exact same pump as you in this video only my fuel inlet and return line are on the opposite sides as your pump.. does this mean my plungers have to face the opposite direction as yours? Or do my plungers still go in the same direction as how you did yours? Any help would be greatly appreciated
The problem I’m having is the fuel stop valve is not shutting the fuel off.. my rack moves smooth and so do the plungers. I have tried to flip the plungers 180 degrees and I still get fuel coming out of the pump and the stop valve still won’t shut the fuel off. Im stumped
@@tractorsmarinemechanic thanks for your reply, I figured it out, it wasn’t a lost pin but that was a good suggestion as they are easy to loose.. the issue was actually quite simple, I was using mechanics wire to tie over the shut off leaver to make sure it would cut the fuel off but didn’t realize that the stop leaver was not bottomed out against the adjustment bolt.. apparently the stop leaver will not work unless it’s fully touching against the threaded bolt that adjusts the leaver. So needless to say once I tightened the mechanics wire a bit more to hold the leaver more firmly over while I turned the engine over the fuel stopped coming out of the pump. All is good and I have the engine up and running again. Thanks so much for your videos!
I have a Kubota L2350DT and it looks like i'm going to have to remove the pump and clean up the internals. I assume that the intake manifold will have to be removed in order to remove the pump from its housing. Is there anything I need to know in regards to the pump orientation with the forks on the throttle linkage. Or does the pump just simply lift out after I remove the fuel line and the associated mounting bolts.
@@tractorsmarinemechanic Thanks for your reply. Are the machined cuts on the plungers supposed to be oriented facing the rack? I think that in most videos that seems to be the case, but its hard to be certain. I did test my fuel flow just after re-installing the pump, and prior to connecting the the injector lines, and everything seemed good with the fuel control. I do seem to have a low speed miss, but that may be due to not having the idle stop properly adjusted yet. The skip goes away with a slight increase in RPMs. Your videos are very good by the way, I hope they are paying you well where you are working. Just a little more emphasis on the plunger orientation would be awesome. What is your fist name? Mine is Don. Thanks again for taking the time to post these videos. Maybe you could consider making some injector rebuild videos in the future.
Got a question My Kubota K 008 mini x is blowing smoke and I have case pressure If you take the dip stick out while the engine is running It will blow oil out Will this fix the issue???
@@tractorsmarinemechanic like the time in the video you showed the delivery valves, plungers and barrels. like at 25:45 you have it completely tore down.
Awesome video, I’m the kind of guy where If i can just watch the job being done once I’v got it down pat. I have a question, I bought larger plungers for my Kubota D902 engine, the guy who makes them claims it will give up to 5hp more with the right amount of air.. what is the difference of running larger plungers Vs. just turning the fuel screw? Basically I wanna know why someone would want larger plungers to get more fuel when they can just simply turn the fuel screw to allow for more rack travel.. I assume both methods allow for more fuel but they do it in different ways? Which way do you suggest is better if you want to add a little more fuel to the engine? Thanks so much!
@@tractorsmarinemechanic howcome? I assume you just keep things original which I understand, your not in the business of modifying pumps but I’m just curious to the affects
@@duchuntr001 thanks so much buddy! Exactly what I wanted to know, I had a feeling that’s what it was but just wanted to be sure. I’ll prolly toss them in tom and see what happens
Is there any way to turn up this pump . Or how do you advance the timing. Not much information on this one. I have on on my kubota zero turn mower. Very informative. Thanks
If you want to advance...this kind of injection pump,you can turn the plunger barrel housing or plunger holder.move from left to right.thank you for watching
@@tractorsmarinemechanic just watched, liked and subscribed. Now about advance. You can do it by removing or replacing with tniner one gasket between pump and block. Moving holder gives more fuel. Correct me if I am wrong.

The cuts on the plunger is facing on the rack and you were right.my next video I will do best I can to show you more clearly.
Will this fix it getting too much fuel? My Kubota is blowing white smoke that smells like raw fuel and I already replaced injectors

Larger plungers will increase fueling(volume) across the entire rpm range. The fueling screw only increases max fueling under load.

Check the control rack if hard to move just reassemble again.control rack must be smooth to move
If you put those fuel pins in with the slot on that side your engine will run away.
