⚙️ Key Features

• Applies from a production change point onwards
• 69 applications across TAD, TD, TWD and TID engines
• Lubricating and Oil System group

🔌 Function

Provides the calibrated closing force behind a valve in the lubrication circuit, setting the pressure at which that valve lifts.

⚠️ Common Signs of Failure

• Oil pressure reading low, high or wandering
• Spring collapsed, shortened or with a broken coil
• Coils rubbed bright or corroded and pitted
• Valve buzzing or chattering under load

🛠️ Service Notes

• Do not stretch a tired spring to recover pressure, as the rate is what sets the setting
• Inspect the valve, seat and bore for wear at the same time, since a scored bore will hold the valve open whatever the spring does
