CAUTION
Carefully turn the crank

Be careful, that the two
dowel pins 8 in crosshead
pin 4 do not jam in the pis-
ton rod foot.

For installation a new compression shim,
note that there are two different
compression shims, see below. Use an
applicable one for installation. Do the
installation in a reverse sequence to the
removal.
Note: Please note the correlation
between setting screw ’ST’ on
measuring gauge 94225 (see
