Land Rover Part Number: ERC9060 - Right-Hand Exhaust Valve Rocker Assembly
ERC9060 is a right-hand exhaust valve rocker assembly for the 2.5L 4-cylinder naturally aspirated diesel engine. Fitted to the rockershaft, it transfers rotational movement of the rockershaft into linear action at the exhaust valve stem to open and close the exhaust valve during the engine cycle. It pivots on the rockershaft and forms the mechanical link between the cam-actuated mechanism and the exhaust valve, taking the loads imposed by the valve spring and contact forces; contact surfaces are typically hardened to resist wear. Signs of wear include pitting, scoring or excessive lateral play on the rocker arm or rockershaft, which can alter valve timing and valve seating and affect combustion and exhaust flow. Use the compatibility data below to confirm fitment against your V.I.N.

Frequently Asked Questions
The ERC9060 rocker arm converts the rockershaft's rotation into linear motion at the exhaust valve stem so the exhaust valve opens and closes during the engine cycle. It pivots on the rockershaft and transmits loads from the valve spring and contact forces; mating faces are usually hardened to resist wear. Common failure modes are pitting, scoring or excessive lateral play on the rocker or rockershaft, which can alter valve timing and seating and reduce engine performance. For Defender 2.5L NA diesel applications ensure correct positioning on the rockershaft and secure fastening during installation.
