IH 666 with Weak Hydraulics

Anonymous-0 · Oct 13, 2008

My nieghbor has an IH 666. This summer the Hydraulics became very weak. The 3pt arms will raise by themselves but if you put a 3pt post hole auger on it and it will not raise it. Also, he has a loader for it and he can raise the loader by itself just fine but if he puts a round bale on the loader he can maybe get it 5 inches off the ground. The loader is plumbed to the rear SCV's. Can anyone give me a clue as to what the problem might be? I know alot about John Deere 2510's and 2520's but not much about IH 666's. Thanks. Paul in WI.

The 666 has 2 pumps. Would not have if it did not have 3pt hitch, problem could be the piggy back pump or relief valve. Most likely the pump. It is in the left side of the TA housing.
