DIESEL ENGINE

Free Length and Tilt of Valve Spring

1. Measure the free length (B) of valve spring with vernier calipers.

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

2. Put the valve spring on a surface plate, place a square on the

side of the valve spring.

3. Check to see if the entire side is in contact with the square.

Rotate the valve spring and measure the maximum tilt (A).
If the measurement exceeds the allowable limit, replace it.

4. Check the entire surface of the valve spring for scratches.

If there is any defect, replace it.

W10289350

Valve Spring Setting Load

1. Place the valve spring on a tester and compress it to the same

length it is actually compressed in the engine.

2. Read the compression load on the gauge.
3. If the measurement is less than the allowable limit, replace it.

W10784360

Oil Clearance between Rocker Arm and Rocker Arm Shaft

1. Measure the rocker arm shaft O.D. with an outside micrometer.
2. Measure the rocker arm I.D. with an inside micrometer, and then

calculate the oil clearance.

3. If the oil clearance exceeds the allowable limit, replace the rocker

arm and measure the oil clearance again. If it still exceeds the
allowable limit, replace also the rocker arm shaft.
