Nice video. Wish I found this prior to diving into my pump. Similar kubota 3 cylinder in a jacobson turfcat. Hadn't ran in 10+ years, water in the fuel. I pulled the injector pump out. I was difficult to get out because the throttle slider was frozen and it ended up breaking on the gears that rotates the plunger inside. (slightly older design to yours). Called kubota, they tell me that dont sell parts for the pump but they would end up sending it to a diesel shop like D&W. These guys were great. Similar problem with finding parts, I send in some pictures of the pump and have the parts the next day. Got the thing running after a bit of time. Wish there were some videos of pump assembly, trade secrets i believe. Hi from Alden

Interesting video Pete. I've acquired an engine in the same range to rebuild in part for entertainment and also to do an engine rebuild video for my channel (and have found the workshop manuals online). Just a point of note that the D902 is one out of a series of similar engines, including the one I bought (a D662), D722 and the D902. They seem to also use the same pumps on engines like the Perkins K103-07 3 cylinder diesel (Which I've also bought). Presumably the same issue would apply to those and indeed all similar diesels.

The injection timing is set by adding or subtracting the shims under the injection pump. This Kubota has fixed timing like most lawnmower gas engines. A lot of automotive diesel injection pumps have variable injection timing. I installed a Kubota 905 diesel in a Geo Metro and it had driveability issues because of the fixed injection timing.

I was thinking about doing the same, 3cyl kubota in a geo , did you ever get it right? How is the power? Could a turbo be added? Milage? Thanks would appreciate some info, did you build a adapter?

@kimmer6 2 жыл бұрын

@@redfuel6bt Power...terrible. Going from 54 hp to 24 hp makes it a flat land vehicle only. I forgot about the car long ago but still have it. It's not a simple swap at all. Nothing fits. I built the adapter, modified a Suzuki Swift flywheel, clutch, starter, and had to make a vacuum pump to work the brakes. The oil pan hangs low and needs mods to provide clearance. The worst part is that the oil filter is exactly in the way of the right axle. A complex adapter needed to be made to switch it over to the front side of the engine. The fixed timing injection pump makes driveability poor. The governor had to be modified to hit 3600 rpm from fixed 1800. When you were ready to shift and hit 3600, the power cut back completely. But it got around 70mpg during the week I tested it. The registration expired and California would not renew it without the original engine. I have a turbo but it still sits on a shelf. I used to build random things like that but nearing age 70, no longer have the interest. I build solar generators for fun now.

I have an electrical external shutoff not the one attached to the timing cover. Thanks.

I had a power loss problem I found number 3 cylinder (that's the cylinder if your standing in front of the engine looking toward the rear of the engine), was dead, and also had a loud clatter noise in the rear of the engine. I pulled the injector out of number 3 cylinder and done a compression test which resulted in a real low compression reading. Just for the fun of it I took a piece of bailing wire about a foot long and lowered it into the cylinder until it touched the top of the piston then I reached around to the front of the engine and grabbed the pulley and turned the pulley back and forth and found I had to turn the pulley as much as two inches in either direction to get any response out of the piston. Immediately I knew where the clattering was coming from and the cause of the misfire and low compression. So I pulled the oil pan off and found the rod bearing had spun and the rod itself was bent in the number 3 cylinder. So at this time I'm in the middle of rebuilding it. Just wanted to share my story on how I diagnosed my engine problems.

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.

i have an f2000 with a d950 motor. i recently had similar issues with smoke and diminished power. just to see what would happen i added sea foam and hoped it was a stuck injector. 15 mins later it returned to normal power with no smoke. i got lucky but more times than not start with the simple things first. nice video thx.

I have a similar issue with my mahindra 2015HST. I’ve replaced the injectors without improvements. Next is the solenoid fuel pump, which I’m going today. I will also clean the fuel tank when I do that. If it doesn’t change anything though, I will break into the injection pump and change the head gasket while I’m at it. My only fear is valve clearance. I know nothing about it and I’m worried about screwing it up when I reassemble it. Do you have any advice here?

Hi Pete, I have a Shibaura 3 Cyl diesel that appears to be very similar to your Kubota. I just got it and it wouldn't start. I bypassed all of the shutdows by running power directly to the fuel cut off solenoid. I found that the mechanical fuel pump was bad so I installed an electric fuel pump I had laying around. Anyway, long story short, I ran the fuel pump and loosened the injector fittings to bleed out any air. Still wouldn't start. Suspecting the injector pump, I pulled off the injector lines from the injector pump and I get very low output from only two of the pumps ports. I took the pump out and disassembled the top half making sure everything went back exactly as it was. Everything looked fine. The cam followers were all stiff but moved freely with resistance. The little arm that moves side to side worked fine as well. Should I have gotten good flow from the pump when I turned the engine over? I cleaned everything and put it back together but I still don't get much flow. I got the engine started but it doesn't run well and dies within a few seconds. Now I'm thinking injectors, injector timing, or possibly a cracked block.

@PetesGarage 6 жыл бұрын

It has to run for awhile until all air bleeds out. You will have to start it many times before it will run, then it will be rough for up to 10 minutes.

@paulcalif 6 жыл бұрын

Thanks for the reply Pete! Mine only runs poorly for a few seconds then shuts down, I must have started it 30 times. I just watched a video of a guy in Australia who fixed a similar injector pump and his fuel was shooting 6 feet with the injector lines removed. Mine is barely going 6 inches. Did you look at your pumps discharge with the injector lines off? I may be barking up the wrong tree but I really expected to see the fuel spray out of that pump with some force.

@PetesGarage 6 жыл бұрын

This sounds silly, but I found a huge wad of debris in the fuel tank blocking flow to the fuel line

@paulcalif 2 жыл бұрын

@@Djkyle65 Yes, in my case it was the injector pump. I swapped the bad one for a known good one and my engine ran fine. Then I took the bad injector pump apart, inspected it, nothing obviously wrong. I was able the lap the critical parts with diamond laping compound. Before you go that far, make sure your fuel pump is working. Bad fuel pumps are a common problem. I've worked on a lot of diesel light towers.

You'd have to do the valve adjustment anyway, the head gasket wouldn't necessarily be exactly the same height and will affect the distance from the camshaft to the rockers
