I have a D17 series iv and I just got the motor replaced. Everything is fine except the fluid is leaking out from the Power Steering Control Valve assembly. Actually, from around the worm shaft and the seal from the rear cover. I'm thinking that the seal needs replaces and wonder if anybody can tell me where I can get the seal.

AGCO has the seal. You have to roll the axle out from under the tractor. Easy fix. Done many of them.
