Important Things To Know About Timing Belts

Timing belts play a crucial role in the interconnection of the various parts and components of the engine to promote a synchronised function in the crankshaft and the camshaft. It facilitates the harmonised opening and closing of the engine valves at proper timings and intervals, leading to unimpeded combustion.

Timing belts like Optibelt Omega timing belts have a significant role in the proper functioning of numerous machines and engines. So, let us gather more noticeable facts and information about timing belts and understand how they work and what their functions and specifications are.

What are timing belts?

Timing belts are thick bands made of rubber that have hard teeth and ridges on their inside surface that help them to key with the cogwheels of the crankshafts and camshafts. They are used to power and facilitate functions in water pumps, oil pumps, and injection pumps, as required by the design of the engine. They are widely used in internal combustion engines to make the valves of the engine open and close in a rhythmic manner in time.

What are the uses of timing belts?

Highly efficient timing belts, including Optibelt Omega, has the following uses and functions:

  • It plays a significant part in successfully carrying out the combustion process by efficiently controlling the piston and the valves.
  • It controls the valve operation by connecting the crankshaft and camshaft together.
  • It takes care of the integrated opening and closing of the valves of the engine.
  • It eliminates the need for external energy to operate the opening and closing of the valves by using the mechanical energy of the combustion engine.
  • One of the crucial functions and uses of timing belts is that it restricts the piston from critically striking the valves.
  • Despite being a single belt or device, it greatly contributes to the operation of multiple components like the upper balance shaft sprocket, lower balance shaft sprocket, camshaft belt drive gear, balance belt drive gear, balance belt tensioner roller, and timing belt tensioner roller.

What is the working mechanism of timing belts?

The timing belts harmonise the closing-opening function and timings of the crankshaft, camshaft, and exhaust valve. It helps in the intake of fuel and air entering the combustion engine, along with controlling the exhaust valve to let the smoke or exhaust escape. The belt keeps the engine coordinated and maintains its ability and productivity.

When to replace the timing belt?

The occurrence of these symptoms signals the need to change the old and worn-out belt and replace it with a new Optibelt Omega timing belt:

  • Reduced engine power
  • Overheating of the engine
  • Occurrence of vibrations or shaking in the engine
  • Difficulty in starting the machine or the vehicle
  • Rubbing or squealing noises coming from the belt
  • A ticking sound erupts from the engine
  • Oil leaking from the engine
  • Irregularity in the working of the engine light


After going through the entirety of the blog, the usage and importance of timing belts can be easily deciphered. However, the need to get the timer belts from a trusted and reliable company like ‘Bolton Engineering Products Ltd.’ can never be emphasised enough as they provide the best quality belts that are sturdy, durable, and hold unmatched efficiency in easing out the working mechanism of the valves or the engine.
