TC24DA loosing power after 30 minutes of use...

[thclimer]

I'm doing this today V1....it had been running fine right up until he got the fuel for me while i was tilling his garden! Figure it wont hurt just to be safe but it smelled like diesel going in but who knows???

Thanks thclimer, i certainly see why you would recommend that...it seems to be a restriction issue but maybe there is a fuel pump that pushes fuel thru the injectors??? i don't know squat about these little 3 cyl diesels...i'm hoping someone on here has some experience with these jap diesels and can give me some direction!!! BTW - i see you have the TC33...that's the tractor i wanted but the 0% interest for 48 months back in June of 2005 sucked me in on the TC24DA! It's funny how easy it was to justify a smaller tractor when the payment was much lower....LOL but if i had to do it over again I would have gotten the TC33 instead!

I know very little about this stuff as well, but I'm fairly sure you do have a fuel pump and a fuel solenoid cut off valve. If either of these failed your engine would shut down, but since it runs for 30 minutes without issues I doubt these are your problem, just keeps sounding like a starvation problem. If you are going to drain your fuel this just might flush out your problem. Where are you planning to drain it from.......after the glass bowl?

Yes, I've enjoyed my TC33 and its implements especially the backhoe, I've sometimes wished I bought bigger.

Best of luck and let us know what you find.

You can go to the NH website and in the Parts section see a breakdown of the fuel system. Most diesel systems have a a tank with an exit strainer, a shutoff valve, tubing to connect to the fuel filter(s) ad then from the fuel filter a tube to the injection pump and then tubing from the injector pump to the injectors and a return to tank line fo excess pump fuel. Often there is a key accuated fuel shut off solenoid valve to shut the engine down.

Most fuel tanks have a strainer ahead of the drain valve and that can get clogged with debris restrictig the flow. Algae can live at the fuel/water(from normal condensation) interface and they form globs of snot like crud that can clog a strainer. Rocking back an forth can move the glob from the strainer causing it to move away from the fuel outlet of the tank. Try removing the line at the tank and draining the tank into a clean receptacle. If it dibbles or is intermittent, blow back on the line with compressed air or use a wire until you drain out all the fuel . Then remove the strainer and see what you can find on it. You may have to take a piece of wire to see what on the bottom of the tank. Take a half a gallon of fuel and pour it into the tank and have a clean container to catch the drainage. Examine that for crud. strain that half gallon of fuel and keep pouring it into the tank to flush out all the debris.

above link takes you to parts section for new holland agriculature ((construction equipment is a different link))

if above link does not work. goto
New Holland
click your country ((above is for north america)) ((make sure you go over to ""agriculture"" or ""construction"" pending on your equipment))
on next page click on ""parts""
then ""parts search""

========
type your model in top left hand side and click "search"

click the plus """ + """ signs on left hand side to expand things. part diagrams on top right, and part descriptions on bottom.

=========
warning if you leave website page open for say 30 minutes, it will log you out. and you will most likely need to go back through the clicking to get back to the parts section ((rather annoying)) but liveable. rather have parts and diagrams vs nothing at all.

thanks guys....i will keep you posted on my findings!!!

pulled fuel line to drain tank and nothing seems plugged, refilled the tank with new fuel, filter was disassembled cleaned and a new element installed (again), purged the air and i'm testing the tractor tonight to see if this solved the problem....

much to my surprise this tank is not gravity fed....the fuel line enters the top of the tank so apparently there is a fuel pump that "pulls" the fuel from the tank??? see link below;

Nothing unusual came out of the fuel tank....hope this solves my problem but i've got a funny feeling it wont!?!?!

Can't see the link you provided. I'm surprised it isn't gravity fed. On my 2003 TC-24D it is. There is a barb or something coming down from the bottom of the tank where the line connects held on by a hose clamp. I had to change the fuel filter assembly a year or so ago because the shut off broke. I accidentally pulled the fuel line off the tank. I had diesel fuel going everywhere - only had 1/2 gallon or so in the tank, but it sure did make a mess. Ended up having to take the dash apart in order to get the line back on the tank.

In the parts sheet I looked at Pipe #18 looks like it comes from the bottom of the fuel tank to supply the filter. Make sure that is not plugged. Take a flashlight and look at the bottom of the tank to see if there is any crud there.
There are two other pipes that go into the top of the tank, one is a return to tank from the injector pump and one appears to be a vent from the top of the filter to the tank. You better take a closer look at the lines because there is no lift pump that supplies the filter or the injecter pump per the parts manual.

re-reading your thread. and what you have stated.

at first thought, everything was timed to the thermostate kicking on/off to help keep engine cool.

but then i caught comment of hyd oil filters. that actually does make sense to me. if the "hyd pump" for say FEL. (front end loader). ran right off a gear from the main drive shaft or like. and if i am picking up from what i have read here on TBN last couple month.s the hyd pump. constantly pumps hyd fluid regardless if you are using FEL or not. the pump pumps fluid up to the valve, then through the valve, then back to the reservoir tank. and cycle repeats. until you use leveler or joystick to operate FEL. and in that case instead of pump pumping oil through the valve, it directs OIL to the hyd cylinders on the FEL.

with above said. if the hyd pump, is pumping hyd constantly. it would mean, any clog in the hyd lines, and/or hyd filters (reservoir tank screen / filter) perhaps filter before or maybe after hyd pump. is clogged. and is causing excess pressure to build up. this excess pressure is causing the tractor to bog down.

there could be a secondary hyd pump perhaps for 3pt hitch arms and perhaps a mid pto hyd pump as well. and the PTO could be independent of all the hyd pumps.

it always seems to vary when reading over comments here on TBN and other folks problems. of how things are setup on different tractors, i might be completely off with above. *shrugs*.

Jerry, you are correct the fuel line is connecting to the bottom of the fuel tank and this too was removed to drain the tank....i can't see the bottom of the tank using a flashlight as you suggested. However, based on the "flow" it seems to be free of any debris.

Boggen, I did a complete hydraulic fluid service which included changing both filters as recommended by my dealer when the problem first reared it's head....the dealer actually suggested this to be my problem when I went back to get another fuel filter....but after replacing the hydraulic oil and both hyd filters the problem came right back?!?!

It would seem to me if the hyd pump was in question or debris in the system were an issue, wouldn't disengaging the PTO (roto-tiller) and/or stop using the FEL and/or engaging the clutch help the engine regain it's loss of power??? I certainly understand where your coming from and the dealer seemed to think it was the "sub micron" filter being plugged up in my hydraulic system but the hydraulic oil and filters had less than 125 hours on them and i'm not working in a real dusty environment.

Bear in mind this tractor has less than 180 hrs on it and the hydraulic oil was serviced at 50 hrs....i change oil and fuel filter every year before going into the winter months. My tractor gets more use in the winter moving snow than it does in the summer months since we no longer keep horses (not moving manure anymore!)....it sees some tilling, planting and bush hogging in spring and summer but the vast majority of it's run time is moving snow.
