Land Rover Part Number: ERR3343 - Rocker Arm Assembly - RH - 300Tdi
ERR3343 is a Rocker Arm Assembly - RH - 300Tdi. Fitted to the cylinder head valve train of 300Tdi engines, this right-hand rocker arm conveys the camshaft's movement to the valve stems to open and close the intake and exhaust valves. It mounts on the cylinder head rocker shaft and bears against the valve tip; correct rocker geometry and secure mounting are essential to maintain valve clearances and to minimise wear on contact faces.

Frequently Asked Questions
The ERR3343 rocker arm assembly sits on the right-hand side of the 300Tdi cylinder head and transmits camshaft lobe movement via the rocker shaft to the valve stems, timing the opening and closing of intake and exhaust valves. Worn contact faces, damaged trunnions or excessive movement can cause incorrect valve clearances and noisy running, so replace if such wear or damage is found.
