In the recent months I have done lots of additions to the hydraulics to my YM 2020D. New Power Steering Kit from Hoye, replaced the loader valve with a Brand Hydraulics LV22, new pump and added some hose etc to make it work better. As some may recall, with the installation of power steering I lost the loader function at lower rpms that I had before. I also upgraded my pump from a 7cc to a 9cc per the suggestion of Hoye. Didn't make much of a difference. I started documenting my flow to make sure I had it all put together correctly and noticed I have a hose that loops back onto the hydraulic block under my seat. Anyone know what purpose that serves? I included a picture of the looped hose and the diagram I created.

hydraulicscan0001.jpg100_4959.JPGHere was that loop on my old 2002D. I removed it, installed a headless plug and then plugs where the hose fittings were. That is made for auxilliary hydraulics same as the diverter blocks you see on some models.

Wooops, messed up from an old mind. The headless plug must be "removed" if you take the hose loop or auxilliary hoses off. That is what I did. I will scan and post the page out of the 220/226 manual which is the same as the 2002, 2020 and probably some others.
