- Self-Lubricating Design: Integrated grease pocket ensures smooth operation over extended periods without the need for frequent lubrication.
- Accurate Tensioning: Built-in spring mechanism delivers consistent belt tension, reducing slippage and extending belt life.
- Wide Compatibility: Suitable for V-ribbed belts in Ford, Volvo, and other vehicles that use the APV2552 specification.
- Easy Installation: Standard mounting hardware and clear torque specifications simplify installation for technicians.
Applications
The Dayco APV2552 Tensioner is engineered to fit a broad range of vehicles that employ V-ribbed timing belts. Common applications include:
- Ford models such as the Focus, C30, C70, S40, and V50.
- Volvo models including the V50 series.
- Other manufacturers that use compatible belt systems.
Installation Guidelines
- Preparation: Ensure the engine is cool and disconnect the battery to prevent accidental start-up.
- Remove Old Tensioner: Loosen the mounting bolts, carefully detach the tensioner from the belt path, and remove any residual debris.
- Position New Tensioner: Align the APV2552 with the mounting flange, ensuring proper orientation of the spring housing.
- Tighten Bolts: Use a torque wrench to tighten bolts to the manufacturer’s specified value (typically 15–20 Nm).
- Belt Adjustment: Rotate the crankshaft by hand until the belt reaches the correct tension, then re-check bolt torque.
- Final Inspection: Verify that the belt runs smoothly over all pulleys and that there is no excessive play in the tensioner arm.
Maintenance Tips
- Inspect the tensioner annually for signs of wear or damage, such as cracks in the housing or a loose spring.
- Check belt tension regularly; if the belt shows excessive slack, replace the tensioner promptly to avoid belt failure.
- Keep the tensioner area clean from oil and debris that could compromise lubrication.
