Kubota D902 Diesel - Bogging Down, Blowing Smoke

[@paulkennedy9824]

Great description of the diesel motor and how it works . Just a little too simple for the average home owner . You are very skilled at mechanical work. Thanks

[@PetesGarage]

Thanks Paul, it's worth trying, you never know unless you try.

[@paulcalif]

I ended up swapping my injector pump for a known good pump and now the engine runs great. I went on to completely dismantle the original pump, and lapped the mating surfaces with diamond lapping compound. That pump works now too. Thanks for the encouragement.

[@PetesGarage]

That's a great idea. These engines are very simple and easy to work on.

[@ryy597]

may i ask why you decide to change your pump?

[@paulcalif]

@@ryy597 I had two engines (in light towers). One ran great, the other one barely ran and smoked alot. I swapped fuel pumps, no difference. Swapped filters, fuel and air, no difference, finally, I swapped the injector pumps and the problem moved from one engine to the other.

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

[@kimmer6]

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.

[@PetesGarage]

Interesting, I can see how that would work.

[@redfuel6bt]

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]

@@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.

[@BensWorkshop]

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.

[@PetesGarage]

Lots of parts are common and similar. I had to use a part number that was not exactly the same.

[@pointseeker]

I have an issue with an exmark that has this issue. Someone rubuilt the blown motor and it has never started since ill be running some tests tomorrow. The theory there was more than likely a fuel issue before and someone tried to start it with ether and blew a rod out-of the side of the block. I just hope the guy rebuilt it correctly.

@@PetesGarage Well nice fix!

[@dangerdanger7311]

Hi Pete, why didn't you just replace the springs and or new injector instead of purchasing a new pump?

[@PetesGarage]

Diesel engines are considered industrial. I would have rebuilt the pump, but the part numbers are not made available and parts are impossible to find without being a distributor. It's kind of a huge money racket.

[@dangerdanger7311]

Gotcha

[@brucejones2354]

Also the separate pumps have to be calibrated so that they pump the same amount of fuel per stroke, and without a service manual for the PUMP it is very difficult to get it right. Best to have it overhauled by a shop that specializes in fuel pumps, or do as Pete did and just buy a new one.

[@davidblalock9945]

I had this same issue with my pump. I took the pump to my local tractor supply. they swapped it from a rebuild they had on the shelf. $125 bucks after core. I was out the door 15 min, back to mowing in about an hour.

[@jamespalmer9556]

Petes Garage i wouldnt have trusted just replacing the 1 broken spring either, highly possible and probable that the other two springs would go bad too, so i agree you made the right desicion in putting a whole new pump on

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?

[@PetesGarage]

If you don't rotate the engine with the head off you have nothing to worry about

[@FlyingAceAV8B]

So ended up taking it to a shop. There is at least one bad cylinder and they’re gonna tear it down. Hopefully it’s just one set of rings.

[@howardhaberern5686]

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.

[@PetesGarage]

If an injector is leaking it will pressurize the cylinder and prevent it from starting

[@Dlong54]

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.

[@PetesGarage]

It does take patience to align the shuttle. The shims are for pump timing. I don't remember the head torque

[@domantor11]

@@PetesGarage do you know what order the shims go in ? I made a mistake and threw mine out like a dumbass. Not thinking lol. There was 3 of them and i have 3 new ones

[@PetesGarage]

The shims will be different for every pump. You might have to go with trial and error

Hello, what is the cylinder head torque for the engine please?

[@PetesGarage]

27.5 to 31.1 ft-lbs

[@manuelfuentes5438]

thanks, I already added the torque 31 lbs, but I am leaking coolant through the cylinder head gasket into the crankcase, the gasket does not have Gasket?

[@PetesGarage]

I've had that happen, it ended up being the wrong gasket. You need an MLS gasket

Hi Mr. Mechanic: I have a kubota BX2370with a small three cylinder diesel. I have changed the filter -fuel pump and it still bogs down under a small load. Is there any advice that you may have??

[@PetesGarage]

Change the fuel in case there is water in it, and look in the gas tank for an obstruction blocking the fuel line.

[@cmdrrgh]

Good chance your fuel jelled, you can go to a auto parts store and buy a can of fluid that immediately breaks this up. Costs about $30 not cheap but better than taking the tank off, also change your fuel filters. Kubota users two of them

[@juanvaladez1408]

where did you buy the injection pump??

[@PetesGarage]

Some online store

[@stlevel15]

Expensive pump, why didn't you rebuild your old pump, seemed simple just replace the spring right?

[@PetesGarage]

Yes, but I could not get the springs and he needed it fast

[@alexg8849]

if I run the engine with this condition, the lean condition will cause engine damage?

[@PetesGarage]

Lean is always bad

Pete, thx for the video..when I reinstall the pump it doesn't sit flush,, seems to be hovering and I have to push down to rescrew the Allen bolts. Is this normal?

[@PetesGarage]

Make sure the shuttle is lined up with the spool
