5525 No hydraulics

[M Neely]

Parked my 5525 in the shed at the end of hay season 2023. Thought I would start and drive it around some. Well no hydraulics. Nothing. No steering, no lift. Was fine when parked. Full of oil. Main strainer was cleaned in 2022. Very little in it then. Can not see any reason for an air leak on the suction side. seems as if pump is not running?? Going to check if there is any flow at the pump tonight. Do not really know where to start. Your thoughts??

A feeder valve that routes hydraulic oil to the transmission pump and to the main hydraulic pump is stuck closed from sitting????

This tractor has the pump mounted on the right upper side of the engine. It does not have a charge pump.

Got it fixed. Orings on the pump inlet manifold causing air leak. Found by prying upwards on the manifold. Could then hear pump working. Replaced manifold and orings. Manifold was old and brittle.
