11) Measure the thickness of the removed tappet using a micrometer.
12) Calculate the thickness of a new tappet so that the valve clearance comes within the specified value.
Valve clearance (Engine coolant temperature: 20°C)
T: Thickness of removed tappet
A: Measured valve clearance
N: Thickness of new tappet
Intake: N = T + [A - 0.20mm(0.0079in.)]
Exhaust: N = T + [A-0.30mm(0.0118in.)]
13) Select a new tappet with a thickness as close as possible to the calculated value.
NOTE
Tappets are available in 47size increments of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to 3.690mm (0.1452in.)
14) Place a new tappet on the cylinder head.
15) Hold the timing chain, and install the intake camshaft and timing sprocket assembly.
