5740C filters

[Tul01]

Hi all, thanks to all the previous posters for the engine and hydraulic filter info on my tractor, but I could never find info on the fuel filter. With 400hrs on our tractor I knew it was time to quit putting it off. My dealer could only come up with the numbers that I had found on the internet, but not one that worked for the fuel filter. The original one on it appeared to be blank, but low and behold when I was finally desparate enough to crack it and spin it to the front, it was a Mitsubishi 34462-00300. Which correlates to a NAPA 3394. Changed it out in about 10minutes, easy job on our tractor. Heres the NAPA #'s for the 5740:

engine oil- NAPA GOLD 7106
trans/hydraulic- NAPA 551715
fuel- NAPA 3394

If someone has already summarized this my apologies, I tried numerous searches.

Would finally changing the fuel filter make the engine run crisper? Just my seat of the pants yesterday, and it could have just been the beautiful fall day, but seemed to rev up quicker and be snappier yesterday. Supposed to be nice out again today, looking for some more seat time.

Brent,

Thanks for the info!! Apparently when you changed it out, you didn't get any air in the fuel line. When my buddy changed out his fuel filter in his 5740C, he had difficulty with air in the line for a short time afterwards.

Got to change out the fuel filter in my 5740C here pretty soon.

I filled it before re-installing and then as soon as it was running, bled the top of the filter housing with the bolt, still didn't get much air out, but seemed to work (maybe first time luck) If you haven't done yours before, just a suggestion, loosen the filter and then take the 2 bolts off the bracket so you can flex the whole unit around before taking the filter off, then you don't have to monkey around the linkage thats right there. I filled and spun my new filter back on when the bracket was still off, then bolted the bracket back up and snugged up the filter. Then fired it back up and bled the remaining air in the filter. Lickety split I was pretty happy that there was no complications.

Thanks Brent for the suggestion and description.

You really should bleed the filter BEFORE you start the tractor to prevent air from getting into the injector pump when you crank the engine with the starter.

If your filter was restricting fuel flow then you'd be unable to develop full power so if you're doing heavy work then changing a restricted filter would make the engine appear peppier.

I did try to bleed it before starting it, by cracking the bleeder bolt and turning the key on, but it didn't appear to do anything, so I tightened it back up and started it and then bled it. Is this one of those times where I should have turned the PTO switch on to disable the starter and turn the key farther to fire up the fuel pump? It didn't seem to be making any noise when I just turned on the key. I guess sometimes it can be better to be lucky than good

I take it your tractor has a lift pump because the tank is below the injector pump. Yeah you should have that running to prime the filter(s) and the rest of the fuel system to the injector pump. Then cranking will allow the injector pump to provide flow to the injectors which will need to be cracked open at their fitting to allow the air to bleed out. Does your owners manual give you a procedure for bleeding the system? It's pretty standard to do that because eventually you'll run it out of fuel (Don't ask how I know this!) and you have to bleed the air out of the system if you want to get it started again.

The manual is vague, but I think it is supposed to be like you say. I did try that, perhaps I just didn't hear it or wait long enough. Thanks, I sure hope I don't run out of fuel, although I do know I have been close.

Thanks

Anyone have the air filter # for a 5740C

Thanks
