KIT-CAMSHAFT 20R7551 - Caterpillar

All winches are rated at bare drum line pull. As the cable drum fills, the line pull will decrease (loss of leverage) while the line speed increases (larger circumference). Therefore, it is recommended to install the minimum length of cable possible for use in your application to allow the winch to operate on the lower layers (smaller diameter) and deliver the maximum amount of line pull.Using larger diameter cable will not always increase strength as the larger cable may be more vulnerable to bending fatigue failure than the smaller rope. Consult your wire rope supplier for their recommendations for the style of wire rope and other rigging best suited to your application. Installation of Spiral Ferrules
Re-usable, field-installable spiral ferrules are available from the factory or from your wire rope supplier. These ferrules are for use with six (6) strand, IWRC (Independent Wire Rope Core) type wire rope. Insert the cable through the small opening and out the large opening of the ferrule. Spread the strands and insert the wedge halves between the strands and over the core. Lay separate strands in the individual grooves in the wedges. Tap the wedges and cable into the ferrule, leaving approximately 3/8 in. (10 mm) extending beyond the ferrule end. The first load applied will seat the cable and wedges securely within the ferrule.
