• Thickness of new valve lifter can be identified by stamp marks

on the reverse side (inside the cylinder).
Stamp mark 788U indicates 7.88 mm (0.3102 in) in thickness.

Available thickness of valve lifter: 53 sizes with range 7.88 to 8.40 mm (0.3102 to 0.3307 in) in steps of
0.01 mm (0.0004 in) (when manufactured at factory). Refer to 

EM-211, "Component"

.

6.

Install selected valve lifter.

7.

Install camshaft. Refer to
