Bobcat 763 Right Side Hydraulic Oil Leak

[praisedale01]

Guys, New to the forum. I recently acquired a Bobcat 763 with low hours and residential use. Immediately upon purchasing I changed oil, fuel and hydraulic oil filters, as well as the hydraulic and engine oil. I knew upon purchase that she had a leak. We all drink a little too much-but today after a solid 8 hour day I found-behind the right side access panel about 1 gallon of hydraulic oil. I refilled the reservoir which accepted 1.5 gallons to the level it was at when I changed the fluids just 2 days prior. I do not see any leaks coming from the drive motor while running or not however I did see a drip from the inside of the machine on one of the hoses Im assuming a coupling above it has seen better days and is leaking on it.... what do you guys think?

Really hard to say, the valve body is on the right side and you could have leaking spool seals. Look close at both sides of valve body for leaks. The large feed hose from the tank to pump usually leak due to loose hose clamps. If your still not able to find leak I usually pressure wash inside real good, let dry, start machine and let run and then you can find source of a fresh leak.

Could be drive motor hose, spool valve or hose going to valve block. What I do is lift the cab up and start the engine then carefully rock the machine back and for against the brake putting pressure on the hoses. If that doesn’t do it I will cycle the tilt cylinder and look around the valve lastly I will push the boom up to the stops looking for leaks. All of these have to be done carefully. Lock the boom up with boom stop.
