V-Belt

 

V-Belt

V-Belts are traditionally found in older motors. A series of v-belts come off the crankshaft, each powering its own individual accessory group such as alternator, a/c compressor etc. Failure to replace a v-belt can cause your engine accessories to stop working as well as engine overheating.

What are V Belt and how do they work

How Does it Work?

  • Provides the best combination of traction, speed of movement, load of the bearings and long service life.
  • Powers various accessory groups in your engine.

How is it Made?

  • May be only rubber or polymer throughout or may have fibers embedded in the polymer for strength and reinforcement.
  • Made in a v-shape to track in the mating groove of the pulley so that the belt cannot slip off.

Why Does it Fail?

  • Belt is over-tensioned.
  • Tension loss caused by a weak support structure, lubricants being sprayed or spilled on belt, excessive sheave wear or belt load.
  • Cracks in the belt.
  • Excessive shock load, or exposure to excessively hot or dry locations.

What are the Symptoms of Failure?

  • Unusual sounds.
  • Excessive vibration.
  • Signs of even wear, cracking, fraying or burned spots on the exterior of the belt.

What are the Implications of Failure?

  • Engine accessory powered by the belt will stop running.
  • Engine will overheat, causing possible engine damage.
