Need members advice, thanks
Well sometimes I can say that if I didn't have and bad luck, I'd have no luck at all
I bought a "new" Kubota OC95 engine on fleabay 3 weeks ago. Upon receiving it, I discovered the injector pump would not work, and the engine was used, not new. I found a local Kubota dealer and took the engine there for repair. They had never seen one of these small engines, but were willing to look it over and get back with a report on what the damage was. The service manager filled out a repair order, I signed it, and left the engine there on May 5th. A week later, I had not heard back from them, so out of curiosity, I called and talked to the service manager. He stated that he had sent the engine to someone else that does work for them and does work on small diesel engines. He stated that as soon as they found the problem, he'd get back to me. Another week passes and I don't hear from this guy, so I call and leave a message, but get no response. Next day (May 19th) I drove down to the shop and asked the manager what was going on, he told me they were behind do to illness, and the guy that has my engine, is also sick, but would be visiting his shop later that day and he'd call me later with a report on my engines disposition. I never heard back from the service manager, so I'm contemplating driving down there for the 3rd time and take my engine out of there and find another shop to perform the work, or maybe do the work myself. I don't mind the time it's taking to get the engine fixed, but I do mind not having any copy of the work order that I signed (I will never make that mistake again), being told the engine is elsewhere to be worked on and last, that the manager does not return calls but promise's to do so. If I take the engine out of there, I'm right back to square one. Am I being too impatient with my dealer?
Thanks,
Cris

Re: Need members advice, thanks
Guys,
Thanks for the replys. I have a manual, but don't have the tools required to lap in injector pump pistons with their bores and the seals required, not to mention being able to test the pump after assembly.
Diesel injector pumps are the most critical part of the engines operation, after that comes the injector itself, and then timing. These small components require knowledge and the tools to perform the work properly. I thought about just buying new components, but the cost could equal what I've spent on the engine I have right now....just a guess, of course. I might go down that route, but first want to hear from as many members that want to put the $.02 of opinion in first
Thank you,
Cris

Re: Need members advice, thanks
Hey Cris,
It might just be something stupid wrong with it, like a gunked up fuel filter or a bad hose going to the injection pump. I flushed the fuel tank on my engine and replaced the hoses before I even tried to start it. The line going to the injector was full of air, I just cracked open the fitting at the injector and gave it a few spins with the compression release open until fuel squirted out and no air. Then I tightened up the fitting, gave it a couple more cranks until I heard the injector "wheeze", flipped the release gave it a crank and it fired on the first catch. This stuff ain't rocket science, I think that most of these engines are designed so that the average mechanically inclined third-world farmer can keep them running for a lifetime. The engines certainly seem to out-last whatever they were originally bolted to, otherwise good used engines would be really scarce.
I'd get the engine back and hope that they didn't monkey with it yet. As far as timing, I think that most of the pumps are shimmed to adjust timing and as long as the same shims go back under the pump you should be OK. But, I wouldn't bother fiddling with either the pump or injector, I'll lay odds that it is just no fuel in the injector line. If that's the case you could crank it over for a month and it still wouldn't purge the air, so little fuel is pumped with each stroke of the pump with no fuel in the line the pressure will never get high enough with just air in the line to cause the injector to release and purge the air. Also there should be an air bleed screw down on the injector pump, this would just have to be cracked open a turn or two until fuel drips out of it by gravity from the tank. I'd also throw some Power Service diesel additive in with the new, clean fuel at first just to clean things up a bit and give some extra lubrication. I started my engine up for the first time when I got it on about 50-50 kerosene with a good slug of Power Service mixed in and let it run for a while. I shouldn't have to mention, but it wouldn't hurt to clean out the oil sump and put in some nice fresh oil, run it for an hour or so and change oil again.
Good luck and keep us all informed on how you do with this.

Brad,
Thanks for the words of encouragement. I did narrow it down to the injector pump. I believe the piston is stuck, but am afraid to tinker with it. If I get it back later this week, I'll tear into the pump and see what happens.

Re: Need members advice, thanks
Dont dissasemble the pump yet !
Take it of the engine and spin it a while with a handrilling machine
With fresh diesel and a bit of heat from a paintstripper , there
is a fair chance you can get the plunger(s) moving again

Re: Need members advice, thanks
Well, the sun may be shining sometime this week
I went down to the shop to pick the engine up. As it turns out, they had sent the pump out to be fixed, and claimed it would be back today for assembly and testing. With any luck, I'll have the engine back by the end of the week...maybe

Got my engine out of hock, finally!
Called the repair shop this morning hoping to get some good news, I was told that the fuel injection pump ordered 11 days ago has come up missing. I was told they'd look into finding out what happened. I was taken back, as I hoped the engine would be ready to come home this weekend. 2:40 pm, I get a call saying my engine is ready, so I tore my ass down to pick it up and get home. Upon reaching my home20 I had the little gem unloaded (manually) and running like a charm. This engine has a nifty key start ignition switch with cool stuff like "glow plug" and "start". Dude at repair shop told me not to worry about glow plug in all but cold weather. Just rotate crank till the compression release will hold in cocked position, and let 'er rip. When running, engine makes normal diesel knock, but does not exhibit the "crack" noise from then engine cases I'm used to. Engine runs the range of idle to max rpm without the usual diesel smoke....I'm impressed.
Will get back on my install and what I've got to do to get back on the road.
Thanks,
Cris

Re: Need members advice, thanks
Coachgeo,
Yeah, it's all good now. Guess I'm too impatient But there again....
Anyways, I sabre sawed off the old pulley on engines crank, all I have to do is remove rust so my Comet 500 will slip on. I'm thinking of starting the Kubota once I have it mounted in my bikes frame and grinding off 1/4" of the cranks diameter where it exits the case taking it down to 1" diameter so I can get my Comet drive unit closer to the cases. I've done this before...it's nasty business but only takes 15 minutes or so to do. The Kubota is built to match the Yanmar L100 (God of 10hp air cooled engines) in most physical aspects regarding size, bolt patterns, weight, etc.. That's good news for me as my Kama clone engine is also built to those same specs.
In addition, I've got to figure out how to "loosen" up the controls so a cable can pull the throttle open and allow spring return, right now, the throttle is tighter than a horses ass in fly season, because of design. Also, stopping the engine is done by pushing the lowest lever towards the flywheel side, so I'll be able to rig up some sort of easy to get to means of killing the engine. I'll have to integrate the alternator output into my bikes wiring, hopefully this isn't a big deal....
I told the guys at the Kubota shop that my next project is gonna be a 3 cylinder engine into a bigger frame with 6 speed tranny, like Curtis is doing... Will have to break the piggy bank to afford the tranny!

Re: Need members advice, thanks
Okay, got my old engine out of bikes frame, took an hour under the 98°F heat here in Texas Kubota was stripped down earlier in the day just to see what other problems I'm up against. Aside from the flywheel being rusted to hell and back, and there is a good amount of red clay dust on the engine castings, I can't find another problem. Took some photos to post, but can't figure out how to do that....

Okay Coachgeo I'll give it a try.....
As you all can see, I'm about ready to get engine into place. After photos were taken, I had to drill and file extra hole to make it all work out. Took me a week of late afternoon HOT sessions, but I got it done. I'll post some pics of engine in frame tomorrow.

Re: Need members advice, thanks
Thanks for the kind words guys ,
Yesterday, I took her out for a 2 hour ride with a full tank of fuel. I made several stops looking for some titty grips for the handle bars, but came up empty handed...sure miss the titty grips from the late '6o's Anyways as for a road riding report, here goes..... The OC-95 is either under stressed or tight. It will not drag my bike faster than 45 mph. I'm hoping it will loosen up in time or I'll go a different route. One thing I can say for that damn noisy Kama clone engine is it was happy to rev, but always sounded like it was going to explode. Personally, I don't like riding a time bomb, so the quiet nature of the Kubota is welcome, I just have to breath some life into it. I don't know about you guys, but a Kubota powered tractor is about as exciting as watching the grass grow. It just rev's up and doesn't do anything to get you off...kinda like a 3-1/2 hp B&S lawn mower. On the other hand, the clone engine teases you into thinking you're really getting somewhere on a wing and a prayer! So after installing my killer fish tail exhaust, I expected a lot of noise......no way, rather the distant low tone note of exhaust unlike anything I've ever heard. My clone engine would make your ears bleed, this engine is just the opposite. It seems like it takes everything it has to push exhaust out the end of the pipe. So after two hours of riding, stopping and rapping to Harley riders at our local "V Twin" shops, I got home with a fully charged battery and 1/2 a gallon less fuel.....ain't this a bitch?

What a monster rear sprocket
I think the biggest reason your kubota is quieter is because it's liquid cooled?

Think that is an oil cooler on it in other pics thus not a water cooled.Sphere wrote:What a monster rear sprocket

Way I heard it, take it with a grain of salt, If a diesel engine is quiet (diesel kncok wise), particularly an older model... then its timing is off. The knock noise is indicative of the explosive force that occured in the combustion chamber? Quiet knock.... lower pow going on in the cylinder(s), lower output at the crank.

Re: Need members advice, thanks
Engine is air cooled and Coachgeo got the oil cooler part right. Never thought about the timing being off, perhaps I need to remove a shim or two under the injector pump.....food for thought. I wonder if there is a good solid way to check the timing????

Re: Need members advice, thanks
Your Kubota dealer (or the folk they shipped your IP off too) might can find out for you how to set "for diesel fuel" according to what their engine designer considers the best spec. Older MB for example uses the "drip" method. A tiny tube added somewhere and you meansure how much fuel drips out or something to that affect.balboa_71 wrote:... I wonder if there is a good solid way to check the timing????
Point is this ONLY sets it to a predetermined spec. One difficulty with tweaking for different fuels in a diesel such as veg oil fuels.... the spec. would be different and their is no "ordinary man's" tool to measure combustion to evaluate efficiency. Same would be for example if your using different injectors or your pump is really from a different model engine that you adapted to fit your engine orr....
Some I've discussed with use a uphill grade (but not a killer mountain) that does tax the engine a bit and drive it over a measured distance that they can use consistently and in easy reach of their home/shop. They drive it and measure speed over the distance. They keep toying with the IP till they get max speed.

Re: Need members advice, thanks
Chris,
The quiet idle is due to the design of the injector with the previously discussed spiral machined in. The manual calls for injection timing to be 13-15 degrees before TDC and the timing procedure seems fairly straight forward.

Re: Need members advice, thanks
Coachgeo and Ron,
Thank you both for offering discussion on timing. As Coach mention, the fuel itself may play a part of setting the timing. Ron, I'm not sure I can perform what Kubota recommends with any certainty of getting it right. When I first got my Kama clone, Diesel Dave helped me adjust my injector pump up and down with shims to play with the timing. The advance on a clone engine is extreme! When I was thru with the tinkering, I ended back where I started in the first place. My issue was noise and knock with the clone engine....now I'm lacking power, and that may mean a simple removal of shim(s) to get more advance. Will have to see....

Re: Need members advice, thanks
The reason your engine is so quiet is because the head is oil cooled, surrounded by a sound deadening jacket full of oil rather than the amplifying effect of fins for air cooling.
If your only reaching 45 then it sounds like you are down on power but if the motor is new then it's not surprising as it needs 100 hours or so to loosen up.
If you have had the injector replaced then it should have been re-timed as manufacturing tollerances need to be accommodated in the setup.
It's not a difficult task to do, just takes a bit of care, but to be honest it's easier to do a running test after removing a shim and see if it improves.

Dave,
Okay, I'll take a shim out and see what happens. I've done that before with no problems. I know the guys that replaced the pump didn't do anything but just replace the pump. I had asked them to check the injector spray pattern, but after all the bad luck I had with them, I decided to get my stuff out of there asap. When you and I talked about this 4 years ago, I was making shims and playing with the timing everyday....right now I don't have the energy with the heat and all ....did I mention getting older???
Thanks,
Cris

In addition to the sound dampening effects of the oil, these quotes from the manual.
Regarding the pump element -
"The plunger is provided with a low speed retarder to maintain the combustion sound low under no load".
And with regard to the injector -
"Due to the use of a throttle type injection nozzle, the fuel injection quantity is small at the beginning of injection, and the fuel injection amount increases gradually for the main fuel injection. This type of injection nozzle features smooth combustion rise and quiet combustion".
If only we had those features for our clones.

Re: Need members advice, thanks
Last night I decided to re-tighten my torque converter just as a precaution. While up on the centerstand, and engine warm, I fired it up and pegged the throttle looking for wobble and what a note the engine makes at 3,600 rpm The fishtail exhaust really resonates, so knowing I can't get it to do that while riding, I think my gearing might be a tad to tall for this engines rated 9.5 hp.. I'll give i month more break in time and see if I don't need to drop the jackshaft sprocket 1 tooth.
