TD5 2.5L Engine Timing System LR060395 Land Rover Engine Timing Gear

Vehicle Compatibility Table

Manufacturing Process

1. Material Forging

   • SAE 8620 alloy steel billet, closed-die forged to minimize internal porosity.

2. Precision Machining

   • CNC gear cutting (DIN 3962 standard), tooth surface roughness Ra≤0.8μm.

3. Heat Treatment

   • Carburized layer depth 0.3-0.5mm, surface hardness HRC 58-62, core toughness HRC 30-35.

4. Quality Inspection

   • CMM verification for gear profile tolerance (AGMA 2000-C95 standard).

   • Magnetic Particle Inspection (MPI) for micro-crack detection.

Critical Notes

1.Installation Warnings

• Reverse Installation Prohibited: Laser-etched "FRONT" marking on gear face. Incorrect installation causes timing misalignment.

• Mandatory Tool Usage: TD5 engines require special tool (LRT-12-000) to lock crankshaft/camshaft.

2.Maintenance Recommendations

• Run-In Check: Re-tension after 500km of operation.

• Lubrication Requirement: Apply Loctite 572 sealant (not regular grease).

Product Functions and Roles

• Ensure Precise Timing: The timing gear works in conjunction with the timing chain/belt to synchronize valve opening/closing with piston movement, preventing severe engine damage such as valve collision ("interference").

• Reduce Friction and Noise: High-precision gear design minimizes mechanical noise during engine operation.

• High Durability: Made from OEM-grade materials (e.g., hardened steel or high-strength composites) to ensure long-term wear resistance.

Replacement Recommendations

• Complete Kit Replacement: It is recommended to inspect or replace the timing chain/belt, tensioner, and idler pulley simultaneously to avoid secondary damage caused by mismatched components.

• Professional Installation Required: The timing system demands extremely high installation accuracy and requires special tools (e.g., crankshaft locking pin, camshaft locking tool).

• Maintenance Interval: Generally recommended to inspect the timing system every 100,000–150,000 km (refer to the vehicle’s service manual for specifics).
