Common Problems This Belt May Correct

  • Startup squeal, chirp or belt slip
  • Weak airflow or a blower running below normal speed
  • Black belt dust around the motor or driven sheave
  • A cracked, glazed, stretched, frayed or hardened belt

Check Before Ordering

  • Read the complete number printed on the original belt whenever possible.
  • Confirm a 1/2-inch A/4L profile and 45-inch outside-length designation.
  • Inspect sheaves for polished, rusted, widened or damaged grooves.
  • Check shaft alignment, bearing drag and the tensioning mechanism.
Pro Tip: A new belt will not permanently stop noise caused by worn sheaves, misalignment or failing bearings. Correct the drive problem first, then set final tension to the equipment specification.

Installation Notes

  1. Disconnect and lock out electrical power.
  2. Release belt tension according to the equipment service instructions.
  3. Do not pry the replacement belt over a pulley; create enough slack.
  4. Clean and align the sheaves, then set the specified belt tension.
  5. Rotate the drive by hand, reinstall guards, restore power and test.

Frequently Asked Questions

Are A43 and 4L450 the same size?
They are commonly dual-rated for this 1/2-inch, 45-inch outside-length size. Product construction and duty rating can still differ.

Can AX43 replace this belt?
AX43 is a related cogged performance alternative, not an identical wrapped replacement. Verify that the equipment permits the construction change.
