When's the last time you changed your fuel filter and checked your pump oil?

Hi,
How many hours on your engine have you vere changed out the injector fuel pump oil?
Sounds like the injector fuel pump governor is sticking. Would be a good idea to drain injector fuel pump oil and replace with new diesel oil and then run engine for a short time to flush out the governor. Maybe do this a couple of times - each time draining the diesel into a container where it can be seen clearly. You will most likely find the diesel dirty to start with and then gradually clean up. Final fill use the recommended weight of engine oil - I have found either 15W40 or 30wt oil works just fine.

Jim.
I have around 200 hours and have not replaced the injector pump fluid. Sounds like this might be the place to start. I think there was a place on the forum that showed how to clean the pump. Ill check it out and let you guys know how it goes.
Thanks...
Thanks...

Little drain plug on the underside, fill vent on top looks a bit like a mushroom. Fill level is determined by another plug on the side.
1. Remove bottom plug and drain
2. Replace bottom plug
3. Remove side plug
4. Remove fill/vent and add oil
5. Stop filling when oil comes out side
6. Replace side plug
7. Replace fill/vent
Should be done at least once a year, I do my own twice: spring and fall. Engine oil is fine, I use compressor oil myself.

Here is a picture of the injector pump on my 284 if that helps you.

I would try replacing the fuel feed lines to the injector pump, sometimes the inner layer of the hoses will collapse causing the engine to starve for fuel and stall. after the engine stalles, in a little while, the vacuum on the hose subsides and the hose opens up and lets fuel run... for a while... then it repeats. I have not seen this on a KAMA but a couple times on foton, but I'm sure it could happen to the kama as well...
I just cleaned out the injector pump with diesel and refilled with 30w ND oil. Still have the problem after about 30 minutes the tractor dies. Two hours later....starts right up. Seems like if I keep the same speed up its ok...Once I let off the accellerator and I accellerate again it just dies. As before several times it seems like it would almost over-rev on its own.....To kill the engine I pull the compression release and the choke (?).
I already replace many of the fuel lines..but ill look at that again. Could this issue be something with the govenor?
Thanks...

Yes. Broken or weak buffer spring. This is something best left to a diesel shop.
It can happen to the best of them.
At work we have four Woodward 2301's w/ EG-3P actuators, and although I've been through the Woodward governor school, I still don't work on them.

Have you checked to see if the small equalizing hole in the fuel tank cap is open? If is is plugged it might be causing similar problem to what you are getting through having a vacuum in the fuel tank?
