Land Rover Part Number: ERR1202 - Rocker Arm and Bush Assembly - Right-Hand Exhaust
ERR1202 is a rocker arm and locating bush assembly for the right-hand exhaust side of the 2.5L 200Tdi cylinder head. Fitted to the valve train, the assembly provides the mechanical interface between the camshaft lobe and the exhaust valve and pivots on the rockershaft to deliver correct valve lift and timing. Correct condition of the arm and bush preserves valve clearance and repeatable valve seating; excessive wear or play at the bush increases valve clearance, alters valve lift, can cause elevated valve-train noise and reduce engine breathing. The right-hand designation identifies the exhaust-side position when viewed from the front of the engine. Replace the complete arm-and-bush assembly where wear or damage is present to restore original valve-train geometry on affected 200Tdi engines.

Frequently Asked Questions
ERR1202 transmits camshaft movement to the exhaust valve on 2.5L 200Tdi cylinder heads. The supplied rocker arm and locating bush allow the arm to pivot on the rockershaft and produce the correct valve lift and timing. Worn or loose bushes increase valve clearance, change valve lift, and can cause excess valve-train noise and reduced engine breathing.
