Land Rover Part Number: LR073775 - Valve Rocker Arm
LR073775 is a valve rocker arm fitted to the cylinder head valve train of 2.0L and 3.0L Ingenium diesel engines. The rocker arm transfers camshaft motion to the valve stem and pivots on the rocker shaft, bearing the contact load between the cam and valve assembly; it helps establish valve lift and timing and maintain correct valve clearance to prevent accelerated wear on cam lobes and valve tips. During routine service, technicians inspect rocker arms for scoring, bending, excessive end-play or wear at the contact faces and replace them where wear affects valve timing or clearance. This part is used across a range of Land Rover models on 2.0L and 3.0L Ingenium diesel cylinder heads and forms part of the cam-to-valve linkage within the valve train.

Frequently Asked Questions
The LR073775 rocker arm converts the camshaft's rotation into the rocking motion that opens and closes the inlet and exhaust valves via the valve stem. It pivots on the rocker shaft and carries the contact load between cam and valve; wear or deformation can change valve lift and timing. Technicians check rocker arms for scoring, bending, excessive end-play or wear at contact faces and replace them when they affect valve clearance or timing.
