Tractor Engine Belt Tips

Handy tips to help in replacing your tractor belts!

Installation Warning:

Always disconnect power supply to machine before removing or installing sheaves or belts.
Never force the belt into a sheave with a screwdriver or wedge. You will rupture the envelope of fabric and break the cords.

Rules of V-Belt Tensioning

  • The ideal tension is the lowest tension at which the belt will not slip under peak load conditions.
  • Check the belt tension frequently during the first 24-48 hours of run-in operation.
  • Do not over-tension belts. This shortens belt and bearing life.
  • Inspect the V-drive periodically. Retension belts if they are slipping.
  • Maintain sheave alignment with a strong straight-edge tool while tensioning V-belts.

V-Belt Maintenance

V-belt drive maintenance is not complicated. Inspecting a V-belt is simply a matter of looking and listening. After belt installation or maintenance, inspect the drive and watch it run.

What to Look For:

  • Oil and Grease: Liquids will increase the chance a belt will fail prematurely
  • Dirt: Impairs traction and increases belt wear
  • Added Loads: Shorten belt life
  • Belt Guards: Ensure cleanliness and safety
  • Cracking: Does not reduce tensile strength; larger sheaves and idlers may reduce cracking
  • Belt Dressing: Do not use any type of belt dressing
  • Vibration: AKA "Whipping"; Caused by not enough tension
  • Heat: Causes overcuring, which will shorten belt life
  • Tension: Proper tension on belts is important
  • Belt Turnover: Indicates misalignment, worn sheaves or excessive vibration
  • Change in Rideout: Indicates uneven belt wear or worn sheaves
  • Lateral Vibration: AKA "Snaking"; Indicates not enough tension
  • Belt Wear: Wear on belt side-walls indicates consistant slippage, excessive dust or rough sheaves
  • Foreign Matter: Can cause excessive wear or breakage

What to Listen For:

  • Squeal: Usually indicates insufficient belt tension or overloading
  • Chirp or Squeak: Usually indicates a dry bearing; realigning the idler may help
