MAINTENANCE MANUAL LINE
NOTICE
Be sure to use the recommended tightening torque for the specified fastener.
NOTE
When possible, always apply torque on the nut.
NOTE
Always torque screws, bolts and/or nuts using a crisscross pattern when multiple
fasteners are used to secure a part. Some parts must be torqued according to a
specific sequence and torque pattern as detailed in the installation procedure.
NOTICE
If not specified otherwise, the threads are not lubricated when fastened.
Measuring tools Calliper rule, dial gauge indicator, micrometer, inner micrometer, inner fine measuring de-
vice, feeler gauge, spring scale up to 50 kp (500 N) (112.5 lbf).
Accepted accuracy for different measuring tools:
Pressure: +/- 5%
Distances:
• Inside micrometer or similar: +/- 0.01 mm (0.0004 in.)
• Digital caliper or similar: +/- 0.001 mm (0.00004 in.)
• Bow micrometer or similar: +/- 0.002 mm (0.000079 in.)
• Caliper or similar: +/- 0.03 mm (0.0012 in.)
The changes above are accounting for:
• variations/errors of tools (when used in normal operating conditions)
• accuracy of tools and their related tolerance
Calibration The professional calibration of your torque wrench is an essential prerequisite for ensuring
the quality of the tightening torques in the long term. Calibration is also a fundamental part
of ISO 9001 certification.
