[QUOTE="BobMelroe, post: 26918, member: 2763"] It has those, but my 600 has a "master relief valve" in the pressure line just upstream from the pump. It's to the right, and just above, the hydraulic filter. When tripped it diverts fluid back to the suction side between the filter the pump. Also, I see there is a check valve in the system that holds 20lbs of fluid pressure to the drive clutches. My other thought was perhaps it was just the watered down hydraulic fliud causing the bypass to rattle like that. I'd hate to tear the whole thing apart and find nothing wrong. My biggest fear woth doing that, is working with nearly 40 year old fittings[IMG]https://www.skidsteerforum.com/DesktopModules/AdverForums/ImageGallery/emotion-7.gif[/IMG] Besides that, I finally have the motor, drive belt, and variable sheave all back in and lined up. And there isn't much room. Have to stand on your head to get down in there. Ahhh, gotta love it! [CENTER]Here is a cropped image of the system. Had to keep it under 500x375 max for clarity. #6 is the Master relief Valve. #8 is the Check Valve for the clutches.
