6i1713 — Caterpillar Valve Seat Insert (Gas) 6I1713

This is a gas valve seat insert, a vital component in the engine's cylinder head that forms the sealing surface for the intake valve. Manufactured to meet rigorous standards, it offers superior resistance to heat and wear compared to a damaged or worn seat, ensuring proper valve closure. Operators may observe a decrease in engine performance, misfires, or difficulty starting the engine when a gas valve seat begins to fail.

Failure Symptoms

Early indications of a failing gas valve seat include a loss of engine power and potential misfires, especially under load. If ignored, the compromised seal will lead to inefficient cylinder filling, rough running, and increased fuel consumption. Continued operation with a faulty valve seat can cause damage to the valve and cylinder head.

Installation Tip

Ensure the valve seat bore in the cylinder head is perfectly clean and free from any carbon deposits or old sealant. Use a proper press or installation tool to seat the insert without cocking or damaging its sealing surface.

Service Note

When replacing the gas valve seat insert, it is crucial to inspect the intake valve and valve guide for any signs of wear or damage.
