SEFCO® F2 Pin Safety Clutches Adjustment Guide

Introduction: This document provides detailed instructions for adjusting SEFCO® F2 Pin Safety Clutches, manufactured by Colmant Cuvelier S.A. It includes specifications for different sizes and configurations of the clutches.

Adjustment Procedures:

Spring Washer Piling: Ensure the spring washers are piled according to the desired adjustment range. Sizes 00 to 5 can have single, double, or triple piling-up configurations.
Size 00: Use a dynamometric key and tighten the nut with an HN 4 slotted key.
Sizes 0 to 5: Insert the braking washer, hand-tighten the adjustment nut, and align the slot with the box engravings. Use the table to determine the number of divisions for the desired torque and tighten the nut accordingly.
Sizes 3 to 5: Use dimensions A and B from the table to achieve the desired torque. Tighten the special nut to dimension A and screws to dimension B, then secure with a lock nut.
Size 6: Loosen all screws, use the table to find dimension X, tighten the nut to X, and then tighten all screws flush with the nut face.

Adjustment Values:

Torque and Divisions: The document provides tables with torque values (Nm) and corresponding division numbers for each size and piling-up configuration. For example, Size 0 single piling-up has torque values of 6, 9, and 16 Nm with divisions of 2, 3, and 5 respectively.
Dimensions A and B: For sizes 3 to 5, dimensions A and B are provided to achieve specific torque values. For instance, Size 3 triple piling-up has dimension A ranging from 11.4 mm to 9.9 mm and dimension B consistently at 8 mm.
Dimension X for Size 6: Dimension X varies from 13.5 mm to 10.6 mm for single piling-up and from 11.3 mm to 9.8 mm for double piling-up, corresponding to torque values from 300 Nm to 2280 Nm.

Conclusion: This guide provides comprehensive instructions for adjusting SEFCO® F2 Pin Safety Clutches, ensuring precise torque settings through detailed procedures and tables for various sizes and configurations.
