Fig. 2.150. Checking the valve spring height
Apply compressive force to the spring and check the height of the spring (fig. 2.150).
If the height is not within specification, replace the valve spring.
- Downforce: 494.9 N.
- Standard height: 27.80 mm.

Fig. 2.151. Measuring valve spring non-perpendicularity |
Measure the valve spring out-of-squareness using a square as shown in Figure 2.151.
Rotate the valve spring 360° and measure the longest distance "A".
If the perpendicularity is not within the norm, replace the valve spring.
Maximum valve spring non-perpendicularity: 1% (2.10 mm).
