Wear or damage to the ring can lead to sluggish response or incorrect boost levels. Inspect the ring groove for scoring or debris before installation. Proper seating is essential for stable operation. Verify that the ring material and dimensions match the S4TW-509 actuator specifications. Consult technical documentation for torque values and assembly procedures. Ensure all surfaces are clean and free of contaminants during reassembly.
