I Still Hate My Tractor

Fred, your an auto tech not a diesel tech, correct?

5 months old and you are going to STICK a turbo on it and fix it ? Absolutely amazing what I see on this site . Carl Bert , where are you ?

LOL looks like I voided the warranty on the blower too Al. No experience with a snowblower. We had 5 inches Thanksgiving morning. I blew snow and rocks till I was blue in the face., My fuel was bought in 1995, no crap but it works fine in every other Diesel I own. What does ULSD have to do with it?

Fred

This time of year is hard on blowers. I usually use my plow truck for the first couple of storms to push the rocks off the driveway. The first year with my blower I spent far too many times replacing shear bolts after finding another rock.

Hows the turbo coming along? Don't listen to the naysayers, it's your tractor.

Aaron I have already, NO difference.
What makes you the fuel expert? Kubota manual states NO high sulfur fuel to be used with this engine. THEN in maintenance it says 200 hr. oil service interval UNLESS using high sulfur fuel then 100 hr. interval. My fuel is fine. Now we have a forum full of fuel experts.

In many cases, the newer engines have particle filters in the exhaust and/or super high pressure fuel pumps (ie: common rail) which cant handle the amount of sulfur in the older 500PPM Diesel.
I don't know waht emissions equipment your L3940 has or what the injection pump can handle, only that its listed as a "Interim Tier4" so I would defer to the engineers at Kubota as to what it can use for fuel. If your dealership says otherwise, I would get that advice in writing so that if it breaks something, you can prove that you were following their advice.

Aaron do think all parts of the world have ULSD fuel? Highly doubtful.
Ultra-low-sulfur diesel - Wikipedia, the free encyclopedia

I know that different parts of the world have different grades of fuel, but MOST are working toward either ULSD or Euro V for Diesel. It is possible (probable?) that in the areas where ULSD (or Euro V) isn't available, they also don't require the same emissions equipment (ie: DPF, etc) so they can remove them and the tractors can then run on higher sulfur Diesel.

Fred, please don't abandon this thread. I really want to see the outcome.

Fred, please don't abandon this thread. I really want to see the outcome.

what he said fred. Its YOUR tractor and obviously you want more power. I have heavily modded motorcycles in the past when i was racing & there is no free ride when it comes to power vs reliability driveability etc. with that being said it took mods to win races for me & it all comes down to money, tech abilities & intended use. Go for it fred & please keep us posted

Fred I'm telling ya there's something wrong with your dang tractor. I'd have the dealer on this one in a heartbeat.

You said at the beginning of this thread: "I use ANY of the hydraulics the revs drop to 1500 or so and the whole machine is thrown into a tizzy"

This afternoon when my wife and son got finished feeding the cows and bedding up the cow shed I tried something with the L3940. I set the RPM's to 2000 and operated the FEL, empty I might add except a HD Round Bale Spear, and the RPM's never dropped lower than 1900. I done this about 5 times up and down just see what it would do.

Try "deadheading" the loader, by curling back and hold it there for a couple of seconds while the pump goes over the relief valve, and see what it does,, I bet about 150 maybe 175 drop. If you think of it, tomorrow when you feed another bale of hay, see what it does with a big ole round bale on the spear. I don't think it will drop much, but it may a little

My point exactly. I would put a gauge on a tee between the pump and the loader valve and see what pressure the OP is getting when he moves the loader. I would also get the testing procedure for the HST and make sure the pressures are correct in the HST.
