Overview
The VVT (Variable Valve Timing) camshaft sprocket is a critical precision engine component found on Land Rover, Jaguar, and Range Rover diesel models fitted with the AJ20D4 2.0L four-cylinder turbo-diesel engine. This sprocket manages the dynamic adjustment of cam timing, enabling optimal combustion efficiency, lower emissions, and responsive power delivery across the engine's full rev range.
If your vehicle displays rough idle, reduced fuel economy, a check engine light related to VVT system codes, or has suffered hard starts, the camshaft sprocket may have worn beyond tolerance or lost hydraulic synchronisation. Original equipment quality replacement restores proper timing control and engine confidence.
This unit ships new, untested, with OEM equivalent construction and specification. Direct fitment via original part numbers—no modification, no guesswork, no compromise to engine integrity.

Installation Notes
Difficulty: Intermediate | Time: 1.5–2.5 hours
-
Disconnect battery negative terminal and allow engine to cool fully.
-
Remove timing cover and any accessory belts as per service manual.
-
Lock camshaft using camshaft locking tool (TDC position) to prevent rotation.
-
Mark timing chain or belt with paint or tape to record original alignment.
-
Remove retaining bolt on old sprocket and carefully withdraw it from the cam.
-
Clean cam nose thoroughly and inspect for damage or scoring.
-
Slide new sprocket onto cam, aligning keyway and timing marks with marked reference.
-
Install retaining bolt and torque to OEM spec (typically 70–80 Nm).
-
Verify timing alignment by checking chain slack and mark positions before proceeding.
-
Reassemble covers and belts, clear any fault codes via diagnostic tool, and test-run.
⚠️ Important: Variable valve timing components are precision-critical. Incorrect installation or timing misalignment can cause engine knocking, reduced power, increased emissions, and catastrophic internal damage. If you are not confident, entrust this work to a qualified diesel specialist or Land Rover dealership. Always use a service manual and torque specs for your exact engine variant.
