Tractor JD 300 Industrial with 300B Loader. I added a woods 3pt mount backhoe.
Model: T4W3D
Serial: 080041T
Over all the hydraulics seem to be somewhat ok, however I have slowly developed a noise that seems to be coming from the hydraulic pump area. It took a while to find a reference to explain the noise, however it sounds like spinning a ratchet in you hand with an extension and hearing the teeth click to each tooth, it slowly winds down when turning ignition off. The sound also could be explained at a card in a bike spoke and slows down when key is turned off.
I replaced both hydraulic filters at the trans and pulled the trans screen and the pump screen and both where very clean. While the pump screen was out I removed the plug above it (suction valve ?) and pushed the valve up from the screen side and fluid flowed through the screen side just fine and the valve moved very easy. I also replaced the o-rings on the manual destroke valve. Since I don't own a manual or hydraulic pressure gauge (Not in budget right now ) I took out my stethoscope and tried to track the noise down. the only noise I could find was coming from the reservoir line from the tank to the pump. Now this is weird, the noise was coming from the pump side of the hose, not the pump hose fitting, not the upper section of the hose or the tank.
I think the pump is a 2000 series, but not sure, haven't found serial numbers yet.
I also have some questions on the rear remote, but we'll get to that.
