Re: 656 hydraulic problems???

to check the outlet pressure just screw a pressure gauge in a coupler and then pull the lever and read the pressure reading.

To check the hose in question, park the tractor nose downhill and remove the 3 pt top link bracket. you should be able to see most if not all of the hose without draining the oil. The relief valve for the remotes is in a transfer block below and on the right side of the seat. This transfer block is bolted to the lift housing and has the remote valve(s) bolted to it. 1 1/8 (Ithink) hex head at about a 45 deg angle, stamped with a part # and 1600 PSI.

You can remove the top link cover,but I have had better luck removing IPTO assy.The hose is alot of the time split on the bottom side towards the front & Ican reach in & feel it with my hand.If the hose is split you need the unit out to put a new one on anyway.If the hose is OK then look up on the RH side above the differential, that is where the manifold is.Good luck.
