Chinese Tractor Owners Association

Hi, I have a Hercules 2254 tractor. The hydraulic pump is driven by a shaft that attaches to the large pulley that runs of off the crankshaft. There is a plate with a extension that drives a shaft that, in turn, drives the hydraulic pump. At either end of the shaft there are identical parts that contain ball bearings so that the shaft has flex on both ends as the hydraulic pump is mounted to the frame and moves independent of the motor When the tractor is in use. The piece I need is the piece that attaches to the pulley and drives the shaft. Hercules was/is I believe made by in whole or in part by Benye Tractor Company. My Tractor has a model Y385 engine. I do not know how to add an image here as the formatting is such that I don't understand how to use it. I do not know how to find the Image URL. I will endeavor to figure it out so that I can post pictures. If you can help me do this than thanks in advance.
