2. Tighten the nut until it touches the end surface of the body, and then tighten it an additional 1/8 turn to ensure that the nut has reached the end surface. If the nut will not turn any further, then it means a sufficient tightening has occurred. Refer to the proper tightening torques shown below.
| Body size | Torque (N·m) |
|---|---|
| 2 | 1.5 to 2.0 |
