My parts Man. says this is for a 187 so it maybe the same one. Again ??? If it is I would remove it and use whatever it takes to clean it Gas, Diesel etc.. HYDRAULIC SCREEN: Yanmar Tractor Parts

I think YM187 is a longer screen. Here's the Hoye diagram for YM186 (YM1510).

Ok have screen all cleaned and put back together. Still have no pump sound nor does it work. Getting frustrated now. Just have to laugh it off I guess

If your sure you have the filter clean then move to the pump. loosen the connection of a line from the pump to the 3Pt. and look for fluid. No fluid, Dirty filter or sheared keyway on the pump shaft Hoye # HWK 522 Shaft key. Very rare for a pump to go bad. That's what I would look for next is the Shaft Key. Keyway/Shaft keys good Then I bet the pump went out.

Ok I will do that next.

I can just take that hose off and see if the shaft spins or take a different one off. ?

Or all the Allen head bolts to the back of the pump
