I have just picked up a used Shaver HD-8 post pounder and would like to hook it up to my T300. The Shaver HD-8 basically has a single acting cylinder with a spring return which is controlled by a 3-way valve. The 3-way valve has a pressure relief set at 1500 PSIG. It has a 3/8" supplly hose and a 3/4" return hose. I guess the large return hose is ment to dump the fluid to the tank quickly with minimal restriction as the springs pull the ram down to pound the post. My T300 has 3 flat faced hydraulic connections which I understand to be high flow at the top (largest connection), case drain in the middle (smallest connection) and standard supply at the bottom (mid size connection). I think that all I need to do is connect the standard supply line to the supply side of the post pounder valve and the return from the valve to the case drain connection but I am wondering about the size of the case drain connection. It seems small relative to the post pounder return line which is 3/4" (the hose looks like 1"). Will I have too much restriction when dumping the fluid out of the cylinder and thereby slow down my pounding stroke? Also, can anyone tell me what the T300 hydraulic attachment pressure is at idle? At higher RPM? Is it adjustable? I'm new to skid steer ownership and any advise or experience would be greatly appreciated. Thanks
