That is on the snowplow that is off the tractor. I can take one of those hoses on the plow and put the other connector on the end and plug it in. I will give it a try.
My bad, I went back to the beginning of the thread and see the connects screwed into your block. Do whatever neccesary to loop those two together. :confused3:
The 186 parts manual does not show a key under the hex drive but Hoye shows a key for it. I would remove the nut and hex drive and take a look for a key, sheared maybe. HYD. PUMP SHAFT KEY_: Yanmar Tractor Parts[/QUOTE]
