- Direct Replacement:Directly replace the unit with an OEM-spec part featuring identical mounting points if you encounter issues such as abnormal belt noise, insufficient spring tension, bearing wear or binding, excessive play or wobbling in the tensioner pulley, bearing clearance failure or bracket breakage.
- Packaging: carton packing and wooden box packing.For example:
Maintenance Points
-
Before installation, inspect the pulley groove for cracks and ensure the bearing rotates smoothly without binding.
-
Use specialized tools during installation; don't use brute force to pry the bracket, as this can cause it to break.
-
Tighten bolts to the specified torque; avoid over-tightening, which could strip the threads. It is recommended to replace the belt and tensioner as a set to prevent compatibility issues between new and old components.
-
After installation, start the engine and observe at idle to check for abnormal noises or any belt wobbling and misalignment.
