The proper valve tappet may also be obtained by completing these steps:
The Valve Lash Specification and Measured Valve lash must be calculated in millimeters (mm)
1. Subtract the actual valve lash on the engine from the valve lash specification (i.e. 0.29 mm – 0.20 mm) = 0.09 mm.
2. Divide the 3 digit tappet number by 100 (i.e. 450 / 100) = 4.5 mm.
3. Add the results of step 1 and step 2 (i.e. 0.09 mm + 4.5 mm) = 4.59 mm.
4. Multiply that answer by 100 to obtain the correct new tappet (i.e. 4.59 mm x 100 = 459).
5. Refer to the table below to find the closest available tappet size to the result from step 4 (i. e. 459 should be
rounded to 460 since there is a 460 tappet).
