Picture of diff lock collar, It might have sheared off the pins?

One more question, when I attempt to engage the diff lock while turning one tire, I can feel the teeth going by, almost like the travel is insufficient to engage it (or there is no teeth left). Best case scenario and the lock collar is in good condition, is it possible the "cam lock"/"wedge" is...

Sounds quite involved, I was hoping for just the right side and not setting up the ring and pinion. Anyway the dealer says the part is discontinued.

Can anyone shed any light on how hard it would be to repair the rear diff lock? When you jack up a rear tire and spin by hand, you can feel the teeth/dogs slip by. Is there any easy fix? I would imagine the axle housing has to be pulled off the center section. Is it engineered with a...

Old post, but since you didn't way what you found, you could loosen each injector line nut one at a time and see if cancelling out that cylinder changes anything, maybe one bad one?

How did you make out? I have to do the same on a grill that has some damage and is not in the original shape which will make it harder to do.

The noise happens even if the 3pt hitch control is all the way down. The lift arms don't jump or move at all when started, so it seems not to be seeing a pressure spike. What quick connect is available to check pressure? With all open center valves, I would think it should be close to zero...

I was hoping not to have to make a donation to the dealer. I find it interesting that I have/had two MXX40 series tractors (one bought new, one w/300 hrs) with the opposite transmissions, but make the identical noise. Since it sounds like a relief valve, I don't think it can be too bad as that...

Fan belt is properly adjusted (300 hr tractor, still at factory adj). 3pt does not leak down on either, makes the hydraulic squeal even with no attachment on the hitch (hitch does not rise at all when started), loader in float or hold, hyd clutch depressed or released, shifted into fwd/rev...

Can anyone confirm that their M5040 or M6040 or M7040 tractor DOESN'T SQUEAL WHEN STARTED ?

On my first M series, a 2008 open station syncro shuttle 5040 which I now replace with a 2012 closed cab hyd shuttle M6040 tractor when started, after about a second or two, a squeak or sometimes a 2-3 second squeal emanates from (what sounds like) under the tractor. The M5040 was more of a...

My M6040 had took a hit to the fuel tank. It bent the mounting brackets up a slight bit. Be aware at least on cab models this can interfere with the throw of the 4x4 actuator and if out-of-place enough, it will keep the 4x4 linkage from fully engaging.

I had a 2008 M5040 and traded up to a cab tractor that ended up being a M6040. When Kubota changed from the 5040 to the 5140 did they add a turbocharger and EGR valve?

The electric controlled 3rd function valve sticks on the loader control lever of my M6040, sometimes. When I used the thumb push button switches, some times you can hear the hydraulics straining after the button is released (the implement is deadheaded at the extreme of travel). If I bump the...

Can anyone running the R4 industrial tires measure the width of their M5040 / M6040 / M7040 at the rear tires? I need to pick one up out of state and my trailer has sides to fit between. And note if the tires are out to max or in? Any actual measurements would be greatly appreciated. (The...

Thanks. I couldn't get that from the dealer. Looks simple. I think I will go for it when it is time to service the hydraulic fluid, the only down side is the fuel tank removal and on a older tractor it may be nice to clean out any water or sludge. I can't believe it prohibits using it to...

Has anyone installed the "cassette creeper gear" option in their M**40 tractor? If so, how hard was it to install, looks simple by the exploded view.

When you say the "engine was designed for it", that was not for longevity, economy, or performance, (longevity being my ultimate goal). It was to pass emissions laws. Kubota engineers didn't say, "Well we can make it better by adding a EGR", no they said "This will work with minimal negative...

To delete the EGR is to plug the line that actuates it. Simple and before you bring it in for any dealer work, unplug it to return to normal. If the line is plugged the EGR cant open, thus it cant send exhaust into your intake. The m**40 series tractors have no computer to throw a code. You...

Roger that, I used to be a mechanic. I was also concerned with the electronic controls. I did some reading up on the auto idle and flow control adjustments for the aux circuit (thumb). I guess it will be a last min decision, either the electronics works or not and how it effects the machine...
