Power Steering & FEL on Yanmar F16 project

Here is the diagram from the FEL

Did he say anything about the PB sleeve. I think you were posting you pixs when I was asking that, my post is above yours and you may not have seen it.

Great progress

P.S. We did it again. In the diagram #2 is the sleeve I am talking about, thats not just a fitting between the hose and valve.

We have to stop typing at the same time. Try pulling the hose off of #2 and then pull #2 out of the valve. It should have a 1/2" to 3/4" long sleeve built onto the inside of it. On the end of the sleeve will be an oring or a machined seal to fit down inside the valve.

Jimmer, Great to see it out "working" !! Very rewarding looking back on all the work, isn't it? If your wife is the one that took the pictures, you did well hiding that ear to ear grin......... wouldn't ever want her to know tractoring can be fun and not just hard work !!! Congratulations !!!!!!

Yes, it is very very rewarding seeing a project actually work. I did have an ear to ear grin, good thing my wife didn't see that

Although, she already knows how much I love projects (both here and at work).

thank you for all your help.

Ahh... That must be it. I just stuck a fitting in it (without the sleeve).

I guess I'll have to find out how to pick up a sleeve.

I'm just tickled that you are following this as close as I am

Unfortunately, I do not have a numbe 2. That must be the problem then

I assume that's a spool specific part. I wonder if I need to get it from Koyker, of if anyone else sells it? (perhaps closer to me than South Dakota).

thank you again. Your help has been invaluable.

 

[DRL]

Yes, it is brand specific, but a local dealer might be able to help.

Great work

I'm guessing that becuase I have a regular fitting in that port, is the reason why my hydaulics are a bit sluggish

I'll go pull the spool off to get a name. Hopefully my local shop will have one in stock (if they don't, they really rake me over the coals on shipping on "special order" parts).

If a priority valve puts oil flow to the power steering all the time that would make your loader work slower..........Larry

Since I don't have the power beyond sleeve, and the snow was flying, I did a work-around.

Because I have a pressure valve before the FEL spool, I just re-plugged the PB port on the FEL spool, and ran the hose that feeds the 3pt from the "Out" port on the FEL. So, now ALL fluid the FEL isn't using goes to the 3pt.

That did give me 3pt hydraulics again.

However, that didn't seem to have any effect on FEL speed (and now, 3pt speed).

What's odd, is that the speed doesn't seem to change even if I'm not turning the wheel (i.e. sitting completely still). From what I understand, I thought that the Priority Valve is only supposed to divert only as much fluid to the PS as it needs. So, if the bottleneck in all of this, was that the PS was taking too much juice, I should have more when I'm not turning the wheel. Right?

When I say slow, It now takes my 3pt every bit of 60 seconds to raise completely, where before the work, it only took less than 2 seconds.

Thoughts?
