• 0.032 kg
• Supersedes 861829

🔌 Function

Limits oil pressure by opening and returning surplus oil once the set pressure is reached.

⚠️ Common Signs of Failure

• Oil pressure higher or lower than specification
• Pressure slow to rise on a cold start
• Valve stuck open, or the spring gone weak
• Debris holding the valve off its seat
• Seat scored or worn

🛠️ Service Notes

• Supersedes 861829, so older parts lists show the earlier number

• Check the bore and spring for debris while the valve is out
