Hi everybody. New to this forum and english is not my first language som forgive me for any spelling errors.
I Have Linde 394 wich seems powerless. It runs slow and when using the hydraulic functions it almost stopps. I have checked timingbelt, changed Turbo, Air volume meter,vacuum hoses for the turbo and all hydraulic filters.
The engien RPM is normal. When measuring the hydralic pressure the pump lovers the pressure for the travel motors to allow the engien to rev up to full rpm. Any ideas, could internal leacks in the motors cause this problem.
