Main Tensioner Pulley Assy
- Articulated arm design: The support arms are detachable, and the tension pulleys and bearings can be replaced individually without cutting or welding, keeping maintenance costs low.
- Easy to maintain and adjust; adjustable from ground level; accessible adjustment nuts on the tension bolts eliminate the need to climb, allowing a single person to quickly adjust tension.
- Visible clearance: There is a standard clearance when the arms are in the open position, making adjustment intuitive and easy to gauge.
Product Description
The main air filter element is specifically designed for use with Lovol series agricultural machinery. It utilizes high-density, highly breathable filter paper and a reinforced frame structure, offering excellent dust retention capacity and smooth airflow. The product features a tight seal and precise fit, effectively filtering out dust, impurities, and straw debris from the air. This prevents contaminants from entering the cylinders, which would otherwise accelerate wear on critical components such as cylinder liners and pistons, thereby extending the engine’s service life. The overall structure is resistant to deformation and vibration, making it suitable for dusty and complex field conditions. It is easy to install and highly adaptable, providing stable and reliable intake protection for the engine to ensure ample power and sustained, efficient operation.
Replacement Guide
- Turn off the engine and disconnect the power supply. Open the outer cover of the air filter housing and remove the main filter element, taking care to prevent debris from falling into the intake duct.
- Gently blow dust out from the inside using compressed air; do not tap or wash with water. If the filter element is damaged or severely clogged, replace it immediately.
- Install the new main filter element in the correct orientation, ensuring the sealing gasket is properly seated. Secure the housing and verify there is no looseness.
- Start the engine and check the intake area for air leaks or unusual noises. Only proceed with operation after confirming everything is normal.
- Refer to the equipment maintenance manual for the replacement interval. Shorten the interval in dusty or straw-filled work environments; replace immediately if clogged.
