Valve Train Components Clean and Inspection

Inspect The Following Areas:
^ Tool Required
- Camshaft Lobe Lift Indicator, or equivalent

^ Inspect the rocker arms and ball at the mating surfaces. These surfaces should be smooth and free of scoring or other damage.
^ Inspect the rocker arms and the mating surfaces. These surfaces should be smooth and free of scoring or other damage.
^ Inspect the rocker arm valve pushrod sockets and valve stem mating surfaces. These surfaces should be smooth with no scoring or exceptional wear.
^ Inspect the valve pushrods for scored ends or bends.
^ Inspect the camshaft and crankshaft sprockets.
^ Inspect the key and crankshaft keyway for wear.
^ Inspect the crankshaft timing chain for binding.
1. Set the camshaft lobe lift indicator on zero.
2. Slowly rotate the crankshaft until the valve pushrod is raised fully.
3. Compare the total lift shown on the camshaft lobe lift indicator with the specifications.
^ Lobe lift:
Intake 0.726-0.736 mm (0.286-0.290 inch)
Exhaust 0.0741-0.0751 mm (0.292-0.0296 inch)
