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.

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

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 .

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

@BiffsEquipment 2 жыл бұрын

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 2 жыл бұрын

Kindly remove again your pump.i think the small pin that guide into the plunger was lost

@BiffsEquipment 2 жыл бұрын

@@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!

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!

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 3 жыл бұрын

Just remove intake manifold And bolts you can lift out that pump

@dmc31405 3 жыл бұрын

@@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.
