Parts for YCT 306S dozer

I need complete hydraulic clutch assembly for forward and reverse, located in the forward transmission housing. Complete assembly including shaft would be preferable. Also need forward and reverse hand operated control valve assembly. Also need hydraulic fluid stainless steel suction strainer. I have the parts manual, with all parts numbers, except for the suction strainer which is not shown in the parts manual. In my tractor the factory installed suction strainer came off and sent stainless fragments into the hydraulic system, ruined the bearings in the clutch assembly.
