ADJUSTING BELT TENSION
Place belt(s) in sheave grooves and tighten by adjusting motor mount. Follow these steps to tension belt.
1. Measure span length. See Fig. 38.
2. At center of span, apply enough force to deflect belt 1/64” for every 1” of belt span. If span is 32”,
deflection amount should be 32/64”, or 1/2”.
3. Use Table 12 to determine amount of force to apply to gauge proper deflection per belt.
Table 12 – Belt deflection settings for Bestorq belts
Sukup products use belts made by Bestorq. Sukup recommends using a Bestorq tension meter to
measure belt deflection. Go to www.bestorq.com or call (402) 423-3077 for more information.
After adjusting tension to desired level by adjusting motor mount, remove any foreign material from inside
of belt guard. Check that all fasteners are tightly secured. Close and latch belt guard.
IMPORTANT:
Check and adjust belt tension after first five (5) and 24 hours of operation, then during
regular maintenance (at least twice yearly).
