[QUOTE="skidsteer.ca, post: 7042, member: 307"] I need a copy of the exploded parts view for the main hydraulic valve on my 773 g foot controls. I'm having trouble with one (close cylinder dirrection) of the aux hydraulic (front couplers) sticking in the on position when I use the momentary switch and continuos flow switch above more then 1/4 throttle. My hyd guy figures its a internal leak in the valve causing the problem (I tried swapping spools and its not electrical) Also my charge pressure is running @ 370 psi at wot (full rpm), the problem goes away if I reduce the rpm at the point when the charge pressure drops under 200 psi. Manual shows I should only have @ 250 psi for the cast iron pump models and the aluminum pump models were around 160 I think (memory??) I have the service manual but it does not have the exploded view of the valve. If you have a parts manual with this info could you forward it to [EMAIL]ken@skidsteer.ca[/EMAIL] or fax to (240) 363-6346 Thanks ken [/QUOTE]
