860036 Valve Seat | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta valve seat in the 0.20 mm oversize, weighing 0.02 kg and listed for 17 applications across the TAMD, AD, D, TMD, KAD and KAMD engine series.

🔌 Function

Gives the valve a hardened landing in a head machined to the oversize recess, sealing the chamber and carrying heat away from the valve head.

⚠️ Common Signs of Failure

• Loss of compression on one cylinder that an oil test does not restore
• Valve clearance shrinking between checks
• Burnt, pitted or unevenly worn seating face
• Seat loose in its recess, or sunk below the head face
• Rough idle and difficult cold starting

🛠️ Service Notes

• The head recess must have been machined for the 0.20 mm oversize — confirm this before ordering rather than after the head is stripped
• Have the seat cut and the valves ground in as one operation
• Check guides and stem seals while the head is apart, and reset clearances afterwards
