Inspection and Repair
Valve Spring
CAUTION: Visually inspect the valve springs and
replace them if damage or abnormal wear is evident.
1. Measure the free height of the springs. The springs
must be replaced if the free height is below the
specified limit.
Standard : 44.6 mm (1.756 in)
Limit : 43.6 mm (1.717 in)

2. Measure the valve spring squareness with a steel
square and replace the valve springs if the measured
value exceeds the specified limit.
Limit : 2 mm (0.079 in)
014RS005
3. Using a spring tester to compress the springs to the
installed height, measure the compressed spring
tension, and replace the springs if the measured
tension is below the specified limit.
At installed height: 35.0 mm (1.38 in)
Standard: 196 N (44 lb)
Limit: Less than 181 N (41 lb)
