TYM T293 Lost Power After 20 Minutes Run time

[kenb1023]

I was brush hogging my back field and the engine started to lose power and RPM. I limped back to the house and looked at the air filter, it was clean. Looked at the fuel filter and it looked dirty. When the new filter came in 2 days latter I pulled the old fuel filter and it was very very dirty with some water in the bowl. I replaced it with the new one. The diagram shows a spring that is at the bottom of the filter bowl but mine did not have one in there. I double checked. Started back up and it seemed to run fine. Ran the brush hog for about 20 minutes and it started to loose power again. What should I be looking at next? If I stop the RPMs come back up but just can't keep the RPMs up under load. It does seem to run a little ruff at low idle. Temps are normal. Trans fluid level is normal. I am not a diesel mechanic so I am at a loss.

When it starts loosing power and RPM, try pull the fuel tank cap out and see if it changes anything. Sometimes the vent on the cap will plug and cause similar symptoms.

Never thought of that but I know that is a trick on some gas cars. Thanks for the tip. The tank is down to a 1/4 tank.

If you have water in the bowl then you have water in the tank. Diesel with water in it is never a good thing. Usually you have to empty and clean the tank, lines and fuel filter. Then purge the water from the injector pump and the injector lines. Best is to loosen the lines at the injectors and let the water out after you have made sure there is no more water in the rest of the system. Not sure which injection pump you have, but some do not survive water in the fuel for very long.

Hope this helps!!

I purged about a quart of fuel from the fuel line and there was no water in what I purged out. So hope that is all there was. I did do the open the fuel cap trick and it actually helped a lot. Took the cap apart and it was a bit dirty and had moisture in the foam inside the cap. Blew out the moisture and cleaned cap. Will see how she runs today. Fuel Tank is now full.

Please let us know how it goes.

Well it still is doing it. This time it was 30 minutes into brush hogging. Frustrating.

Electric lift pump could be goin' bad. Have had a couple lately that didn't fail completely but would quit working after half an hour or so.

 

[kenb1023]

Is there a way to test it? I know it turns on because I can hear it making the same noise it has for years. It is 12 years old by the way.

Looked up the fuel pump, $200. That is crazy

Hello neighbor! Your the 5th member here that lives in the Edgewood area.... small world for sure.
Is this happening every time your cutting? How about other tasks?.

How is the mower ? Everything spinning freely? Gearbox isn't too tight?

Just thinking if something other than the tractor is acting up.

Keep us updated.

Did you change the fuel filter? From what I can tell, water separator is the only thing that was fiddled with.

For the fuel pump, does it have a small 12v lift pump? If so, the auto parts stores sell an inexpensive pump you can try. Just jumper it to the battery to try it out.... if it works, then you can permanently wire it in.

Open up the bleeder at the injection pump when it quits running well, with the key on. May want to do that when cold for reference.

I doubt there is anything distinct on the pump you have all it does is lift the fuel from the tank to the real pump. Just guessing but, 12-volts, 3 to 5 psi, 5-gpm, electric pump should work. You aren’t pulling moving gobs of fuel, and it just needs to maintain positive pressure to the main injector pump.

If you have the manual, it may have specs on the pump.

Hi, I am over on Square H
It has been working fine till now. The last time I had the cutter on was 2019 when my brother was cutting the field for me after my accident. No problem then. I did notice that last winter when I was plowing snow it seemed a bit sluggish in the deep stuff. When the cutter spins up it sounds normal and cuts great. I guess I can try disengaging the cuter when it starts to act up and see if the issue is still there.

Ok, here is something that is really crazy. I looked up the part number for the pump and found ELECTRIC FUEL PUMP FOR 5010|6010|6110 MAHINDRA TRACTOR (16999052300) for $235.00. I went and found Amazon.com: ‎zt truck parts 12V 3-5PSI Electric Fuel Pump 68371-51210 for Kubota D1005 D1105 D905 Engine : Automotive for $15.80. The are identical. What gives? I ordered the $15 one. Can't hurt to try. It is for a Kubota D 1005 D1105 D905 engine. I know these tractor shops need to make a buck but I don't want to pay to send their kid to Yale. LOL

The amazon one is a Chinese copy. The original is Korean made. As far as the price, they aren't quite as high from TYM but still outrageous. All the TYM parts from Mahindra are anywhere from 10-100% higher then from TYM. More Information for AUTOBEST 12D . This is the one I've been using when the customer doesn't want the factory one. One thing I would add, if your new pump doesn't come with a strainer. Install an inline fuel filter before the pump. Most of these are setup were they are pulling unfiltered fuel from the tank. Scratch that. Looked in the manual and this one is setup with the filter before the lift pump.

Well, if the cheep Chinese knockoff works I will look at getting a better one later. Thanks

I took a closer look at the picture from Bill's Tractor and Equipment. It is the same friggen pump with another label superimposed over it. If you look close you can see the Chinese knockoff pump label. Now if that is not flat out stealing/a rip off I don't know what is. I know one company I am not buying parts from.

I always search part numbers. Coming from the auto industry many components on all sorts of gas, diesel, and electric machines come from the same manufactures. Not always but a good chance you will find the direct source that company purchased from. Example my arctic cat sled. AC wanted $380 for the 2 injectors. Looked up the body number. Lone behold it’s a $18 Injector made by many main brand manufactures for several popular 90s-2000s Honda and Toyotas.
