An unknown part

Guys, hat's this lever used for?

 

[gordon21]

Is that connected up to the seat track mechanism?

Feedback rod for hydraulic system. Don't think you should attempt adjustment.

That's how the hydraulic lift system knows the position of the 3-pt arms.

It's related to the control lever over on the right, where you preset your intended height.

While you may not want to adj the link, it does look like the jam nuts are loose. What is the correct length so jam nuts can be tightened and result in correct length rod.

Hmmm...

Now I'm wondering if mine is set up correctly.

I wanna know this also.
I have had problems with a little set offset disc plough. It just wouldn't break up the soil.

I'm pretty sure it is the "Draught Control".

It controls the depth that the 3 point runs at.

I don't know if it limits the lower or upper level or if it stops the 3 point from "jumping" up [stump jumping].

I would love to know the correct settings.

If anyone understands this Position Control rod and has good setup instructions, I'd appreciate a little enlightenment.

Aha!

Followed my own advice, RTFM, and look what I found.

In this diagram, the two jam nuts on the feedback rod are near the end of the threads.

It looks like mine (photo, above) is set up correctly to match its Operating Manual.

I don't have my service manual handy, but is there any info on how to adjust it if it has been assembled incorrectly, as gcp's appears to have been? I'm sure they are all different, like mixture screws on a carburettor.

And that's not the only thing that's been assembled incorrectly on my YM2000, I am amazed this poor thing still runs as well as it does. It speaks volumes of the rugged Yanmar design, and OEM parts used!

I have a set of manuals, so when I get home from Sunnyvale Cal, this weekend, I'll try to figure it out and/or post the manual's adjustment procedure. Hope this will help others, as well me. But I hope I don't mess it up in the process since it seems to work fine as is.

Come to think of it Yanmar Tractors -- Parts -- Sales -- Service is on my way to the property so I guess I can swing by and ask for directions on how to do this particular adjustment.

I'll let you know the end of next week....

Well guys I am back in town and have not been able to find something of substance in the manuals. So, tomorrow I'll go to the Yanmar dealer in order to buy a spare key, and to enquire on the proper adjustment of the feedback rod. Then on to the property to play, where I have no Internet so I'll report back when I get home on Sunday.

 

[gcp]

The dealer wasn't much help this time, no spare key available, plus no precise answer as to how to adjust/fine tune the lift hydraulics. So I fiddled with the valves and rod on mine enough to believe it is now adjusted correctly. The lift speed seems proper, and it appears to hold any load I put on it. The way I figured it out was to go from adjustment extreme to the other and back off to where it appears to make sense.

Sorry I can't be of more help!
