#1 cylinder piston is again set to the top dead cen-
ter on compression stroke.
5) Ensure the valve clearances are within specifi-
cations. If necessary, readjust the valve clearanc-

6) Similar to adjustment procedures used for #1
cylinder, adjust the #2, #3 and #4 cylinder valve
clearances.
NOTE:
• Be sure to set the cylinder pistons to their re-
spective top dead centers on compression stroke
before adjusting valve clearances.
• To set the #3, #2 and #4 cylinder pistons to their
top dead centers on compression stroke, turn the
