Womala Exhaust Camshaft Timing Gear OE LR023931 for Land Rover Range Rover Sport

Product Overview

The Exhaust Camshaft Sprocket LR023931 is an OE-grade variable valve timing (VVT) component engineered for the 5.0L V8 petrol engine (AJ133) in select for Land Rover and for Jaguar vehicles. This exhaust-side sprocket, also known as a camshaft adjuster or timing gear, synchronises the camshaft rotation with the crankshaft and adjusts exhaust valve timing for optimal engine performance and emissions control .LR061550 is the current replacement part, with a supersession path of LR010775 → LR023931 → LR041446 → LR061550 .

Key Features

• Exhaust camshaft position – specifically for the exhaust side; intake side uses a different part number (LR023934/LR061551) 

• Variable valve timing (VVT) – adjusts exhaust valve timing based on engine operating conditions 

• OE-grade quality – Genuine Land Rover specification; available from Gates and other OE suppliers 

• Direct-fit replacement – matches factory camshaft mounting and timing alignment

• Quantity required – 2 per engine (one per cylinder bank) 

OE Cross-Reference

💡 Supersession Note: LR061550 is the current replacement part. All listed part numbers refer to the same exhaust camshaft sprocket for 5.0L V8 applications .

Technical Specifications

Vehicle Fitment

⚠️ Important: This is the exhaust camshaft sprocket for 5.0L V8 petrol engines only. For the intake side, order LR023934 / LR061551 . Not for 3.0L V6 or diesel variants.

Signs of Failure

• No start condition – engine cranks but fails to fire 

• No compression / poor compression – valve timing compromised 

• Damage to the physical gear – visible wear or broken teeth 

• Rattling or knocking noise – from the timing area, especially on cold start

• Check engine light – timing or camshaft position-related DTCs

💡 Extended oil service intervals are a contributing factor to VVT gear failure – narrow oil pathways within the advance mechanism can become restricted by oil film build-up .

Critical – Verify Your VIN Before Ordering

Camshaft sprockets are VIN-, engine-, and position-specific. Two sprockets are required per engine (one per bank) . Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation required – precise timing alignment is essential and may require specialised tools . When replacing the camshaft sprocket, inspect the timing chain, tensioner, and guides for wear. Use new mounting bolts and torque to manufacturer specifications.
