Womala Timing Chain Tensioner LR051008 for Land Rover LR4, Range Rover Sport

Product Overview

The Timing Chain Tensioner LR051008 is a Genuine OE-grade component engineered for the 3.0L V6 and 5.0L V8 petrol engines (AJ126 / AJ133) in select for Land Rover and for Jaguar vehicles. This hydraulic tensioner applies and maintains constant pressure on the primary timing chain, preventing chain slack and ensuring accurate crankshaft-to-camshaft timing. LR095472 is the current replacement part, superseding LR051008, LR032088, and LR010883. C2Z28428 and AJ813898 are Jaguar equivalent part numbers for the same tensioner.

⚠️ Important: This is a hydraulic tensioner, not a guide rail. For the tensioner guide/lever, order LR051013. Both parts are typically replaced together as a set.

Key Features

• Hydraulic tensioner design – maintains constant chain tension via oil pressure

• OE-grade quality – manufactured to original equipment specifications; INA is an OE supplier for this component

• Direct-fit replacement – matches factory mounting points

• For 3.0L V6 and 5.0L V8 petrol engines – AJ126 / AJ133 engine families

• Quantity required – 2 per engine (one per timing chain)

OE Cross-Reference

💡 Supersession Note: LR095472 is the current replacement part, superseding LR051008. All part numbers listed above refer to the same hydraulic tensioner.

Vehicle Fitment

⚠️ Important: This tensioner is for 3.0L V6 and 5.0L V8 petrol engines only – not for diesel or other variants.

Signs of Failure

• Rattling or clanking noise – from the front of the engine, especially at idle or cold start; a known issue addressed by Land Rover Technical Service Bulletin for worn timing chain levers

• Check engine light – cam/crank correlation fault codes due to timing being off

• Engine misfires or poor performance – incorrect valve timing

• Risk of catastrophic engine damage – if the tensioner fails completely, the timing chain can jump, causing pistons to contact valves in this interference engine

💡 A worn tensioner is a common issue on AJ126/AJ133 engines. A Land Rover Technical Service Bulletin (SSM) specifically addresses a “rattle/click” noise from the front of the engine caused by wear on the timing chain tensioner and lever – the remedy is replacement of both the tensioner (LR051008) and the guide (LR051013).

Critical – Verify Your VIN Before Ordering

Timing chain tensioners are VIN‑ and engine‑specific. Two tensioners are required per engine. 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. The tensioner should be replaced together with the tensioner guide/lever (LR051013) and the timing chain (LR032048) for a complete timing service. Follow the Land Rover workshop manual procedure for installation and torque specifications.
