Description

Camshaft Sprocket – GEMS V8 is the timing chain sprocket fitted to the camshaft of the Rover GEMS 4.0L and 4.6L V8 petrol engine.

The sprocket is driven by the primary timing chain from the crankshaft sprocket, synchronising camshaft rotation with the crankshaft to maintain correct valve timing relative to piston position. The GEMS V8 uses a single overhead camshaft per cylinder bank; the camshaft sprocket is secured to the front of the camshaft and must be correctly timed on installation to maintain accurate ignition and valve events.
