FLEXSTEEL BELT REPAIRS
1. Repairs where there is no cable damage
a. This type of damagemay be repaired in amanner more or less normal with any belt in that the damaged area is thoroughly
cleaned and dried, the damaged elements (cover, plies, insulation, gum, etc.) replaced and the new elements cured.
b. If cable has been exposed it is important to use the proper cable cement and cable insulation gum at that point.
2. Repairs involving cable damage
a. If cable damage involved less than 5% of the width, simply trim the frayed cable ends and repair as per (1) above without
inserting new cable.
b. If damage is more extensive, sections of new cable (or pieces cut from spare belt) should be worked in. This makes a
more extensive repair as the new lengths of cable should extend 15" to 24" each side of the broken area and a large
vulcanizer is usually required.
The covers are removed along with insulation gum from between cables. The new cable sections are simply placed between
the old broken ones extending 15" to 24" each side of the break. Cable cement, insulation gum and covers are applied and
the repair is cured. The sketches below illustrate two methods used to step in lengths of new cable.
NOTE: When making cable repairs along belt edges, the tension must be removed from the belt. Even then the edge may be
wavy because the new edge cables will not be carrying tension.
NOTE: • – Top Cover Cut
•• – Pulley Cover Cut
Make approximately a 1" step between
cover cuts around entire repair.
