Jerky LSeries 3pt Hitch Fixed

[unfinished]

If you search google for "Diesel Tractor Me Kubota" it shows that Kubota has a ME series of tractors for some other markets besides US, it's a big tractor though.

My dealer only sells Kubota equipment, as far as I know the mechanics only work from the workshop manuals. The mechanic showed me the manual he used, which covered L2800/L3400/L3700 (not sure about L3800).

As far as the jerky lever, my mechanic noticed that also when he first started looking and was suspicious. He said proper torquing of the valve was critical and also that the lever design was maybe a bit sub-optimal, something about how the lever interfaces with the valve, only a small amount of travel on the end of the lever covers the entire range of lift on the valve. When I got my tractor back, one of the first things I noticed it takes very little hand pressure to push the lever as compared to before. But...I don't know if the L3010 is in the same family as the L2800/L3200/L3400/L3700/L3800, just asking.

And that is just to get the correct WSM # that we need. "...For troubleshooting, disassembling, and servicing there are yet other manuals...." Wonder what those costs? Do you think there's a manual for each; one for troubleshooting, one for disassembling, and one for servicing? :confused2::confused2::confused2:

I think with a new valve and all those WSM's, it sounds like over $1000 just to try it. And at that, it sounds like a lot of try/s.

Maybe we should find "Terry, the 3pt value adjusting prodigy," give him a $1000 collection... about $.20 for each view of this thread (I owe about $5.00) and write up our own bulletin. Then copyright it and license it to Kubota for $100,000!

Maybe the mysterious Terry had access to the 9Y021-18201 manual at Jokergerm's dealer and consulted it to enable him to make the repair. Might be worth a shot to check, Jokergerm. If you get lucky and they do have it they may let you Xerox the applicable pages.

Somebody somewhere must have the manual or it wouldn't be published or for sale. If everybody checked their dealers I bet one of us could come up with it and get the applicable pages Xeroxed and posted. Maybe Messicks would do that.

Hey Harvest Moon, do you have a link to the Messick's page that lists the manual? I couldn't find it.

I just went to Kubota Parts and entered 9Y021-18201 in the "Kubota Part Search" field, not the "Commonly used..." field. That one didn't work

Hmmm....I might have a problem and didn't know it:ashamed: The lever on my 3PT hitch control is so stiff that I cannot move it gently. When it moves it jumps 1 or 2 inches so of course the hitch/equipment jumps 2-6". Wonder if it can be lubed or new sleeves put somewhere.....

There is an external "friction bushing" for lack of a better term on the shaft that the 3 point lever attaches to. Much the same as the throttle lever bushing. If you loosen the locknut on the bushing, you can decrease or increase the force required to move the lever, then re-tighten the locknut once you're satisfied with the effort required.

Thanks Harvest Moon. I was hoping to copy a picture of the cover of the 9Y021-18201 manual to hand to my dealer so he could more easily check if he had one, but Messicks' site had "no picture available". You'd think for two hundred bucks they'd at least give you a glimpse of what you were buying. Oh well.

Ebay had a lot of manuals for sale relatively cheaply, but not one of these.

Yup, table of contents wouldn't hurt either.

In my honest opinion if it was fixed then Kubota would let everyone know.

Well, I have often read these "jerky 3PH" threads, and until now, there seemed to be no hope. Mine is jerky. I have just learned to deal with it.

I kinda was hopefull when it was said that an adjustment was all that was needed, until the post about the adjustment being inside and top-cover needing removed and all. If that is the case, I will continue to deal with it, because for me, living with it is worth not having to take it appart, because it just aint that big of a deal to me.

And I doubt my dealer will be any help. I purchase the tractor 5 years ago, and have not even been back, or complained about the problem to them. So I dont see them being any help (not that I would even want it) if I called them and said "hey, I bought this tractor off of you over 5 years ago and ...".

But at any rate, it prompted me to take a closer look at mine. And there are some plugs and bolts (some look adjustable) on the top cover that I have no Idea what they are, or what is under them. So I posted pics and was just wondering if you guys had any Idea???

most are just "plugs" (???) #60, 40 and 20 (sorry not much help...) Except for #1 in your photo... Assy Valve Safety (again ???)
