Check following:

1. LO pump Relief valve is not properly adjusted

Tighten the adjusting screw. If the pressure does not still increase, open and check the valve spring and contact surface of valve and replace or repair.

2. Suction strainer is contaminated too much

Clean the strainer.

3. Oil temperature is too high

Replenish the lubricating oil or change it and also check the bearing for any abnormality

4. Bearing metal is excessively worn

Replace the bearing metal

5. LO Pump gear is damaged

Overhaul the pump and replace the gear

6. Faulty pressure gauge

Replace or repair the pressure gauge.
