Neighbor has a Farmall 460 for sale. Has a front end loader on it. Start it up and has no power steering and no hydraulics. If I move the fast hitch lever you can hear the pump squawk and it'll hardly move. The power steering does the same thing, makes a squawk then no sound, then squawk, no sound then squawk, exc. The hydraulics on the tractor are what operate the loader, i could not get the loader to budge. Gotta get the loader up at least so i can haul it home. I have not tried filter or checking fluid yet, just wanting some ideas so im not going in blind, any help would be appreciated.
 
Simple first: check the fluid level and if on the full mark add 2 more gallons. If no joy, lift and lower the fast hitch 20 times and operate the steering. If the PTO spins turn it on and watch it as you ,slr it squak. If it stops spinning I will guess the splines are stripped on the Drive from the clutch Pressure plate to the Drive for the TA Pumps and other live systems. Jim
 
Bought or should I say stole a 560in an auction that exhibited those same symptoms. $1800 and 5 gallons of hydraulic oil later everything went to working😎 And drove it home
 
When I bought my 560 hydraulic oil and filter had not been changed for a long time. Had about 300 pounds of hydraulic pressure. Filter housing looked like inside of a baby diaper. I changed filtr and oil but still nothing. Pulled pump and it was worn badly so put in pump out of another 560 that looked good. Hydraulic pressure about 1200 then it dropped off. Changed hydraulic filter again assuming stuff in system plugged it and pressure came right back up. Also lost power steering when pressure down as it uses a pump piggybacked to hydraulic pump. As mentioned check hydraulic fluid level, next check hydraulic filter.
 
Sounds like I could get lucky. Might take hydraulic oil and a filter and see what I can find out in the next couple days.
