3020 leaking hydralic oil

roger coulter Our 3020 started leaking quite a bit of hydralic oil tonight, it seems to be coming from just in front of the hydralic pump.I suspect that a line has a hole in it, any suggestions,we will have to start tearing it a part tomorrow. Thanks Roger
ross It is probably coming from the front seal of the hydraulic pump. There is a small black plastic line hooked onto a fitting on the bottom of the pump, it usually goes to the brake valve, you might want to plum it to a different spot. If the brake valve goes bad it will send pressure oil up through that line then push the front seal out of the hydraulic pump. You can plum that line anywhere on the tractor where it will drain back to the transmission reservoir, it must not have any restriction on it. Just something to look for and hope this helps.
roger coulter Thanks for the reply, we thought it might be the seal or a line going to the pump as it seems to be coming from behind the pump. Can the seal be replaced, don't want to replace the whole pump, have done that before.Can anything else make the seal go bad?When we start taking it apart will we be able to see where it was coming from? Thanks Roger
ross Since you have to remove the front axle anyway, you can support the tractor without the front end attached and start the tractor up and see where it is coming from. If its leaking off the back of the pump the oring might be bad. You should be able to tell where the leak is coming from once you tear the pump down. Also you should check your pump pressure, it should be 2250 psi to 2350 psi.
