Free Length and Tilt of Valve Spring

1. Measure  the  free  length 

(B)

  of  valve  spring  with  a  vernier

calipers.

2. If the measurement is less than the allowable limit, replace it.

3. Put the valve spring on a surface plate, and put a square on the

side of the valve spring.

4. Make sure that the full side is in contact with the square.

5. Turn the valve spring to measure the maximum tilt 

(A)

.

6. If the measurement is more than the allowable limit, replace it.

7. Examine the full surface of the valve spring for scratches.

Setting Load of Valve Spring

1. Put the valve spring on a tester.

2. Compress the valve spring to the specified setting length.

3. Read the compression load on the gauge.

Oil Clearance between Rocker Arm and Rocker Arm Shaft

1. Measure the rocker arm shaft O.D. with an external micrometer.

2. Measure the rocker arm I.D. with an internal micrometer.

3. Calculate the oil clearance.

4. If the oil clearance is more than the allowable limit, replace the

rocker arm and measure the oil clearance again.

5. If the oil clearance stays more than the allowable limit, replace

the rocker arm shaft also.
