Hi everyone, I understand that some Renault and John Deere models share some of the same ancestry so I'm hoping that someone can help with some advice on this problem. The tractor is a Renault Ceres 335X. In order to remove a faulty starter the main large bore inlet pipe and manifold to the dual pumps as per the photo was removed. The pipe that runs vertically to the rear of the pumps was also disconnected. It was the only way to remove the starter. The starter was repaired and refitted. The inlet pipe and vertical smaller pipe were refitted. A minimum of oil was lost when re-inserting the inlet pipe into the rubber elbow below. The oil level was checked and the tractor started and idled for several minutes. The problem is that we have no hydraulic function at all. No steering, no transmission and no front end loader. We suspect that the problem is that the pumps have not yet drawn oil up to them in order to pump it onwards. We have tried to run the engine for as little time as possible. We have even disconnected the outlet pipes on the pumps and primed them with oil, all to no benefit. A brief higher burst of engine speed was carried out without success. There appears to be a very limited flow of air and oil coming from the outlet side of the filter body that is mounted high up on the engine. Is there a venting procedure for this model if the circuit is interupted? Desperately in need of any advice or procedure to return the hydraulic functions. Thanks in advance. DavidP, South Wales
