Installing cylinder liners
Checking cylinder liner protrusion
Fig. 7
Clean the basic bore and the cylinder liner.
Insert the cylinder liner without O-rings into the
crankcase, observing the marking (ensure that it is
identical to the position prior to removal).
Using the dial gauge and its holder, measure the
cylinder liner protrusion at no less than 4 different
points.
Specified values see "Service Data".
Fig. 8
The cylinder liner protrusion is the difference be-
tween the collar height and the collar recess in the
crankcase.

Fit a shim if the protrusion is below the minimum
level, even at only a single point.
The shim is placed under the cylinder liner collar.
However, it may only be used if after installation
the upper tolerance limit is not exceeded.
