Hydraulic problem

Post by drsmith » Mon Jun 11, 2018 11:02 am

Has anyone had any past experience with 990 Implematic hydraulics.We have put a pressure gauge on and only getting 500psi on full revs.stripped it out and took the pump apart but nothing visually wrong ie o rings ect.Put an hydraulic pump on where the pipework where the pump fits and pressured up to find no leaking pipes.All this i must add done by a qualified DB mechanic.Any thoughts on this problem would be a great help.

If the system is holding oil and the pressure relief valves are not relieving then it is the pump.
