Well, I finally found enough free time to install the hydraulic control valve on my 186D for the front mount snowblower and all functions work perfect including the PB for the 3-point.
I have noticed a strange side effect after the install though. When the engine is throttled up the hydraulic pump now whines like it's under a load. If you run one of the cylinders all the way out and hold the valve over the relief the noise instantly disappears. It also goes away when lifting the 3 point.
All lines are 3/8" and the hydraulic pump was silent prior to the valve install. So, here's my question. Does the 186D need 1/2" feed and return lines to allow proper circulation when not under a load?
