Product Description:

 
Auto belt tensioner​
OE number: LR034128
Applicable vehicle type: For Land Rover
 
 
 
The tensioner pulley for the car belt is a crucial regulating component in the engine front-end accessory drive system (FEAD). Its primary function is to automatically or manually maintain the optimal tension of the belts (such as timing belts, accessory V-belts), preventing slippage, abnormal noise, or detachment, ensuring that the engine, water pump, alternator, air conditioning compressor, and other accessories operate normally and efficiently.
 
 
Core functions and importance:

• Provide accurate tensioning to keep the belt in optimal working condition, avoiding faults caused by being too loose (slippage, noise, accessory power loss) or too tight (bearing premature wear, belt stretching damage).
• Compensate for belt elongation: Belts naturally stretch over long-term use, and the tensioner can automatically or manually adjust to compensate for this change.
• Absorb system vibrations: Dampen vibrations generated by engine operation, protecting the belt and accessories, and enhancing system smoothness.
• Guide belt path: As a guide pulley, ensure the belt is correctly wrapped around all pulleys.

Common faults:

1. Bearing damage: The most common fault. Caused by dried-up lubricant and failed seals, leading to wear and jamming.
2. Spring force attenuation: Fatigue of the automatic tensioner spring, resulting in insufficient tension.
3. Armature jamming: Due to dust and corrosion, causing inflexibility in rotation and loss of automatic adjustment function.

Fault symptoms:

1. Unusual noise: Continuous "squeaking" sound (belt slipping) or "rumbling" friction sound (bearing damage).
2. Belt vibration: Visible severe vibration of the belt during engine operation.
3. Accessory malfunction: Generator not generating electricity, air conditioning not cooling, steering assist becoming heavier (due to belt slipping causing loss of power transmission).
4. Premature belt wear: Cracks and severe wear on the side of the belt.
