I have a early model John Deere 3010 and when I raise the 3 point hitch it is a real jerky and has loud screech.... I have change the fluid and the hydraulic filter and cleaned the hyd screen. Please tell me I dont have to replaced the main hydraulic pump. Vince 509 480 8412
 

I suggest you install a 5000# gauge in rear hyd breakaway coupler then engine operating move hyd control to activate gauge. Hyd stand-by pressure should be 2250 psi.
 
Hi Jim,
I did place a gauge on it like you said and the pressure reads about 2000 PSI. Is that a problem?

Jim,

How do you increase the pressure? Is there a adjustment on the main pump? It is a syncromesh transmission.

Look at this thread because 1st photo shows the the hyd pressure adjustment screw. Loosen lock nut & turn screw in to raise pressure.
