Installation and Break‑In Tips

Before installation, apply a circle of lubricant above the snap ring and allow it to penetrate for free rotation. After mounting, perform a proper break‑in: run 3–5 light engagements with no load, then gradually apply load in 2‑minute intervals, cooling between runs. This approach helps establish solid contact and reduces early wear.

These guidelines reflect the data provided and are intended as practical steps to help you achieve consistent engagement and smoother operation over time.
