Checking the technical condition of timing parts

Sprockets, hydraulic tensioner, chain guide and tensioner arm

  • 1. Check the camshaft and crankshaft drive sprocket teeth for excessive wear, chipping, and breakage. If necessary, replace the asterisks with new ones
  • 2. Check the chain contact surface at the tensioner arm and guide for excessive wear and damage. If necessary, replace with new ones.
  • 3. Check the stroke of the hydraulic tensioner plunger and the smoothness of its movement. If any defects are found, replace the tensioner assembly.
