HYDRAULIC - Yanmar Flow for Power Beyond, Power Steering and 3PT

[Scotty Dive]

Nice thread. I'll be watching and bookmarked this. I hope to get a FEL from Fredricks in the future for the YM2610. My co-worker with the YM1720D and FEL has Yanmar factory Power Steering. He's never mentioned any issues with the lack of loader lift/decend, PTO, and power steering issues all at the same time.

Can you get him to share how his is plumbed and loader response?

Can you get him to share how his is plumbed and if he has quick felt response?

Butting in but pretty familiar with factory power steering. The factory power steering goes from pump through diverter valve. The diverter valve tees it to both power steering and 3 point. Second picture shows the power steering unit. Note the return line dumping in the top of the transmission. The line going to to His loader could be plumbed in several ways. Quite confident the 1720 and my old 2002D were very similiar hydraulic wise. When I bought mine The line was cut going from diverter valve to 3 point and loader tied in with out power beyond. I later added power beyond and it did improve quickness, but not much.

I'll ask. He may not be all that tech savy other than, the diesel goes in the tank and the oil goes in the cap with the dip-stick.

BTW, his 1720D has the typical Fredricks Koyker loader setup. Not sure if that helps any unless someone has a Yanmar with OE PS and the loader added by Fredricks.

Scotty it sounds like it the hydraulic flow is plumed like our aftermarket PS is plumbed with the exception a different diverter valve. But I could be wrong. And obviously we have changed the flow of how it was meant to be set up. His seems to be plumbed like Hoyes kit is supposed to be. Also any news on your loader yet??

The only update I can share is that Brand replaced my loader valve under warranty - Swapped it in, but besides testing for operation, I have not been able to use the loader with any weight to test the drop rate under load Hope to get to that soon, but my schedule has been a bit busy to say the least.

I am interested in what you find when time permits.

Yes please let us know what your results are.

I have a little bit of good news....as a reminder, I was having difficulty with my new loader valve and being able to feather the lowering of a heavy object in the bucket. After talking to Brand Hydraulics, I convinced them to replace my loader valve. I swapped it back in a couple weeks ago but didn't have the time to put anything heavy in the bucket to try it out, however this weekend I put in a 600 pound wood stove in the bucket using my forks. The new loader valve work like it should. I was able to feather the wood stove down and control it so one problem solved. As for the plumbing I have yet to do what Jtullis has done but I do have every intention of going down to my local Hydraulics place and printing out some of the drawings that we posted here and having a discussion to see what they think about the whole mess. stay tuned more to come.

Good to hear about the loader valve being the culprit in the feathering down issue. Confirmed my post #24 thinking. Very interesting thread. Will be wating for further developments.
