5.6.2 Tappets
(1) The tappets are offset to rotate during
operation and thereby prevent uneven
wearing. Check the contact of each
tappet and replace if excessively or
unevenly worn.
Note:
When removing tappets, be sure to keep
them separate for each cylinder and intake/
exhaust valve.
(2) Measure the outer diameter of the
tappet, and replace if worn beyond the
limit.
(3) Measuring push rods.
Measure the length and bending of the push
rods.
