Timing change

Timing change

The timing gear plays a key role in each piston engine as it controls the opening and closing of the valves, letting in a mix of air and fuel and letting out exhaust gases. The timing gear is driven by a belt, rarely by a chain. If the belt breaks, the valves and pistons may collide, causing a costly damage. Therefore, the timing gear components, i.e. the belt or chain, tensioning rollers and guide rollers should regularly be changed and checked for any signs of wear.

Tips

  • The timing belt replacement schedule must be strictly followed
  • After buying a used car always have the timing gear changed
  • When changing the timing gear remember to have all of its accessories replaced, too
  • Oil leaks around the timing gear may cause the timing belt to wear faster
