1.Measure the diameter of each tappet bore using the caliper gauge. Measurement positions total four and are in the X and Y directions, at two points (A and B) as shown in the figure.
ADJ2224E023
Standard tappet bore diameter
31.000-31.030 mm {1.2205-1.2216 in}

2.Measure the tappet body outer diameter of each valve using the micrometer. Measurement positions total four and are in the X and Y directions, at two points (A and B) as shown in the figure.
ADJ2224E0292
Standard tappet body outer diameter
30.970-30.980 mm {1.2193-1.2196 in}

3.Calculate the clearance between the tappet and the related tappet bore by subtracting the outer diameter of the tappet from the inner diameter of the tappet bore.

• If it exceeds the maximum specification, replace the tappet or cylinder head.
Clearance between tappet and tappet bore
Standard
0.02-0.06 mm {0.0008-0.0023 in}
Maximum
0.15 mm {0.006 in}
