20513285 Exhaust Valve | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta exhaust valve is an OEM service component used in the Cylinder-Head Exhaust Valve. It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta/Volvo 13-litre and 16-litre D13/D16 industrial and marine diesel application. Technical identification: High-temperature exhaust valve: approximately 46 mm head diameter, 10 mm stem diameter, 191.3-191.4 mm overall length and 45° seat angle; chromed stem with hardened tip and armoured/Stellite-type seat face depending manufacturer. In service, it controls exhaust-gas discharge from the cylinder while sealing the combustion chamber during compression and combustion. Selection must be confirmed by OEM part number 20513285, the exact model/product number, serial number and installed assembly configuration.

🔌 Function

Controls exhaust-gas discharge from the cylinder while sealing the combustion chamber during compression and combustion. Inspect all matched valve-train parts, lubricate contact surfaces, set valve recession/clearance where applicable and recheck after initial operation.

⚠️ Common Signs of Failure

• Low cylinder compression or leakage during a leak-down test
• Hard starting, misfire or uneven running
• Loss of power, high exhaust temperature or excessive smoke
• Burned, recessed, cracked or pitted valve/seat surfaces
• Incorrect valve clearance or repeat leakage caused by guide/head wear

🛠️ Service Notes

• Keep valves in strict order as they come out so anything reused goes back in its own guide and seat, and measure stem, guide and seat wear against the figures in the workshop manual for your engine before deciding what to reuse
• Check a new valve for straightness and check that the seat face is clean and unmarked before it goes anywhere near the head
• Clean carbon from the port and the seat, then grind or lap the valve to its seat and confirm a continuous, even seating band right round
• Renew the valve stem seals, cotters and any spring hardware the manual calls for while the head is apart — the cost is trivial against a second strip-down
• Check valve recession or protrusion relative to the head face, and clearance to the piston, against the manual figures for your engine before final assembly, then set the valve clearances to the manual figures once the head is back on and recheck them after the first running period
