⚙️ Key Features

• 0.007 kg
• 9 applications across the TMD, MS, TAMD and MD series
• Lubricating and Oil System group
• Works with piston 859679

🔌 Function

Sets the pressure at which the piston lifts, holding the lubrication circuit at its regulated value and returning the piston to its seat as pressure falls.

⚠️ Common Signs of Failure

• Oil pressure below normal once the engine is hot
• Warning light flickering at idle
• Spring settled shorter than its companion, or found broken
• Pressure not lifting as it should with a cold, thick oil
• Coils rusted, pitted or with the ends worn square

🛠️ Service Notes

• Renew the spring and piston 859679 together — the regulated pressure depends on both
• Check the oil pump and pickup before blaming the regulator: suction pipe 859728 is the pickup item listed in this run
