Position the first or fourth cylinder at compression top dead center.
1) Remove the ignition coil and sparkplugs for all cylinders.
2) Rotate the crankshaft with a socket wrench (ratchet) (Figure 4) until the top mark (orange) on the camshaft pul

ley is aligned with the timing pointer (Figure 5).
The cylinders are numbered 1, 2, 3, 4 in sequence from the compressor side.
3) Rotate the intake and discharge side pushrods for the first
cylinder with your fingers, checking that they move eas

ily (Figure 6). If they move easily, it means that the first
cylinder is at compression top dead center. Perform the
valve clearance adjustments that are marked ● in Table 1
below (Figure 7).
4) If the check above is not successful, rotate the intake
and discharge side pushrods for the fourth cylinder with
your fingers, checking that they move easily. If these
rods move easily, it means that the fourth cylinder is at
compression top dead center. Perform the valve clearance
adjustments that are marked ○ in Table 1 below (Figure 7).
