Visual check of tappet
Visually check the face of the tappets
in contact with the cam for pitting,
scores or cracks, and replace if
severely damaged. If the amount of
cracks or pitting is small, correct with
an oilstone or grinding paper.
Outside diameter
With an outside micrometer, measure
the tappet outside diameter. If the
measured value is beyond the limit,
replace tappets.
Push rod run-out
Use a feeler gauge to measure the
push rod run-out.
Roll the push rod along a smooth flat
surface as shown in the figure.
