Engine Stays − Checking the Oil Pressure
1. General
Two hydraulic engine stays (1) are installed on the exhaust side and two on fuel side
of the engine.
The oil pressures on the pressure gauges of the hydraulic cylinders must be
checked and compared with each other at regular intervals.
If one of the hydraulic cylinders shows a pressure below 30 bar, which could be
caused by defective O-rings, leaking valves, screwed connections or a defective
bladder accumulator, the one cylinder on the opposite must also be released of its
pressure down to 30 bar.
The defective engine stays must be repaired at the first opportunity. Afterwards the oil
pressure must be readjusted to the required value on all the engine stays, whereby the
detailed instructions of the respective maker must be considered.
