LR061550 Engine Timing Gear For Land Rover 2.2L TD4 /3.0L TDV6 /3.0L SDV6 Diesel Engines

1.Vehicle Compatibility Table

2.Product Overview

Precision-built for Land Rover diesel engines, the LR061550 timing gear guarantees flawless timing system operation—maximizing power output while protecting your engine from costly timing-related failures.

3.Product Features

High-Precision Manufacturing

• Made of high-strength alloy steel or sintered metal, offering wear resistance and high-temperature durability for long-term operational stability.

• Precision-machined tooth profile reduces meshing noise and power transmission loss.

Strict Compatibility

• Matches original equipment manufacturer (OEM) specifications, ensuring accurate timing system alignment after installation.

Reliability

• Designed to withstand the demanding conditions of Land Rover diesel engines, including high torque output and frequent start-stop cycles.

Matching Components

• Typically requires replacement alongside timing belts/chains, tensioners, and idler pulleys (refer to the repair manual for guidance).

4. Key Functions

1. Primary Role:

   • Transmits crankshaft rotation to camshaft at 1:2 ratio

   • Synchronizes fuel injectors, EGR valve, and valve timing

2. Performance Impact:

   • Timing deviation >2° may cause:

     • 15-20% power loss

     • 8-10% increased fuel consumption

     • DPF regeneration failure

5. Installation Guidelines

Critical Steps:

1. Pre-Installation Checks:

   • Measure gear radial runout (<0.05mm)

   • Inspect keyway wear (max. allowable clearance: 0.03mm)

2. Thermal Installation:

   • Heat gear to 120℃ (do not exceed 150℃)

   • Use专用 installation tool (LR-2887)

3. Torque Specifications:

   • Center bolt: 80Nm + 60° rotation

   • Apply thread locker (Loctite 263)

Prohibited Actions:

• No hammering (risk of micro-cracks)

• No direct flame heating

6. FAQ

Q1: When should the gear be replaced?
A: Replacement is required if:

• Tooth clearance >0.15mm (use feeler gauge)

• Pitting covers >3mm² surface area

• P0016/P0017 fault codes appear

Q2: Can the timing gear be replaced alone?
A: Must replace concurrently:

• Timing chain (if stretch exceeds 1%)

• Guides (if wear >0.5mm thickness)

• Hydraulic tensioner (recommended)

Q3: Is post-installation break-in needed?
A: Follow this procedure:

1. Maintain 2000 RPM for 5 minutes after first startup

2. Avoid sudden acceleration for first 500km

3. Perform initial oil change at 1000km
