3 Press the fixed end of the yoke against the valve stem
by pressing down the adjustable end. Screw down the adjusting
screw (3) until it touches the valve end and note the position
of the spanner (pos. a). Now press down the fixed end. Keep on
screwing down while the yoke tilts, until the guide clearance
is on the other side and the fixed end of the yoke starts lifting
from the valve stem. Note the position of the spanner (b).
4 Turn the adjusting screw
counter-clockwise to the middle
position between “a” and “b”, i.e. “c”, and lock the counter nut
of the adjusting screw.
5 Put a feeler gauge
corresponding to the valve clearance
between the surface of the yoke and the shoe at the rocker arm.
Tighten the adjusting screw (1) until the feeler gauge can be
moved to and fro only with slight force. Hold the adjusting
screw and tighten the counter nut. Check that the clearance
has not changed while tightening.
