This was in my hydraulic filter - M7060

[tho2nd]

Changed my hydraulic filters yesterday. I’m attaching a picture of what was stuck to the magnet.

Does anyone recognize it?

I’m currently experiencing intermittent loss of power while running 7’ rotary chopper. Sometimes everything is fine, other times any action that draws on the hydraulics bogs down the engine.

Fuel filter is fairly new, hydraulic filters are new.

Did you know your fingerprints are in the NCIC files…?

Don't what part it is, are you the first owner, have you changed the fluid/filter before. That part is fairly large to make it through the system without getting hung up. When you pulled the drain plugs did any metal come out (it looks pretty chewed up). Check the parts diagrams to see if you recognize the part. That the kind of thing that will take a couple of years off of your heart. Good luck

It looks like a piece of a shift rod. Which side appears to be broken off? Do all the functions on the tractor work?

Look through the parts diagrams and see if anything looks similar.

I’m the first owner and so far, only swapped out the filter…..haven’t drained the oil yet, but I can see that will be necessary.

I poked around looking at diagrams, but haven’t ID’d it yet.

Everything transmission-wise seems to be fine.

Quite the mystery. And yes…….years off my life for sure!

Thanks for taking the time to reply……as far as I can tell, everything is working as it should. I am having a problem with the engine bogging down, but not convinced the two are related.

I hope you still have powertrain warranty? If so I would be calling the dealer before draining the oil. Oil should be included in the repair I would think.

Check with your dealer there was a service bulletin, I believe that’s what Kubota calls them, on certain M7060’s with the injectors needing replaced due to low power.

After corrective actions are taken, I'd suggest purchasing all of the drain plugs/ crush washers and JB Weld magnets to them to capture any material that may be in the system. Even though the filter magnets capture most some can still settle out at the lower areas. Periodically you can pull the plug/s quickly and place the old plug while the magnetic one is inspected and cleaned, then top off any fluid lost. Cleanliness of a hydraulic system cannot be overstated.

Does that “square thingy” slide up and down on the longer rod, or is it fixed?

I have no clue, just trying to use “deductive reasoning” aka SWAG….(Scientific Wild Ass Guess)

 

[aemsee]

I keep looking at that picture, trying to figure out how that could travel through the hydraulic system to end up in the filter. Crazy

It was sucked up through the suction pipe in the differential housing and up to the filter.

I am very certain it is a piece of linkage for the 3-point control under the 3-point lift cover.

Is your parking brake working? I was told that they do break and cautioned to follow the funky swing-wide shift pattern when going into park.

 

[Killer Bee]

agree with both above as plausible.

I highly recommend not operating that machine any further than necessary to diag the failure and locate the source of that broken part.

full function test may reveal the culprit. it's difficult to believe something that size breaking isn't preventing or at least inhibiting a major function in your machine. especially considering the amount of force exerted on it to break. since you haven't noticed a loss of function performance, might be something you seldom or never use that was accidentally engaged while mowing and you didn't notice movement or sound.

my first thought is it looks like a spool valve linkage or toggle, or possibly the spring bias or detent side of the spool.

I also recall a 140k grader that one of my mechanics found a big chunk of metal during a fluid change, fell out of the drain plug though. turned out to be a solenoid actuated neutral lock that worked in concert with the parking brake system. after contacting quinn we discovered there was a pip for it and the dealer repaired that machine and their field techs retrofitted the other machines.

as mentioned above, a thorough scan of the internal hydraulic system and final drive drawings should reveal something similar for some clues.

and once you figure out what it is and where it came from, don't forget to inspect for collateral damage to whatever components were gnawing on it.

good luck!

You are correct, I just found the part in a diagram. It appears to be part of the linkage for draft control.

There's a backstory:

I had to replace the top cover as I'd broken the connection point for the top link. That involved removing the valve body directly under the cover, then installing it on the new. This was my first time opening up a three point hitch housing so I was completely anal about documenting everything with pictures and I was also completely anal about the work area and how I removed each part during the replacement.

So after finding the part in a diagram, I went back to the pictures to confirm it was there when I opened the top cover. It wasn't there.

I was using my backhoe when the top link connector broke....I was prying on a root. When it snapped, it was a tremendous jolt and I suspect that the linkage came apart and fell into the gear housing etc.

Therefore it wasn't there when I opened the housing and I had no idea it was a missing part.

If I haven't bored you too much yet.........I'm experiencing significant power loss when I'm putting the tractor and hydraulics under a load. I can get about 15 good minutes chopping with a 7' mower (on 3 pt hitch). After the tractor heats up, I lose power on inclines or heavy grass. If i lift the bucket...power loss. raise the chopper, power loss. At this point, I can't engage the PTO as it kills the engine

Questions:

-Is my power loss likely coming from the missing linkage and inability for hydraulics to adjust base on load?

or

-Is my power loss coming from one of the linkage components plugging a line.

Obviously no one can know for sure, but I don't understand the draft controls to know how much tthen can impact engine power.

Thanks for the input

Oh they're probably on file somewhere!

Yes.....Aside from loss of power, I've noticed nothing funny with the drive train. Whitetiger identified the part so I think I'm at least starting down the road to repair.

Thanks for the input

It's fixed. Good question tho!
