Valve Spring Inspection and Measurement

Valve Spring Inspection and Measurement

Special Tool
J 22738-B Valve Spring Tester

Inspection Procedure
1. Clean the valve springs in solvent.

WARNING:
Refer to [Safety Glasses Caution].

2. Dry the valve springs with compressed air.
3. Inspect the valve springs for broken coils or coil ends.

Measurement Procedure





1. Measure the valve spring tension using the J 22738-B.
2. If low valve spring load is found, replace the valve springs. DO NOT use shims to increase spring load. The use of shims can cause the valve spring to bottom out before the camshaft lobe is at peak lift.
