(B) 5.00 mm (0.196 inch)
Position the hose clamp to the correct distance from the hose bead. The distance from the end of the hose clamp closest to the hose bead should be dimension (B). Refer to Illustration 2.
For either the 9X-2488 Hose Clamp or the 159-1503 Hose Clamp, torque the clamp to the recommended 7.5 1 N m (66.38 8.85 lb in).Note: Use of a manual torque wrench is preferred to attain 7.5 1 N m (66.38 8.85 lb in). If an automatic torque gun is used, it must be an electric direct drive type (not clutch type).Note: Do not use a pneumatic torque tool. Ensure that RPM of the electric direct drive tool is between 60 and 200 (RPM greater than 200 can damage clamps and will result in improper torque readings).
