Machining cylinder liner height
If, during control measuring, the cylinder liner
does not reach the specified value the liner seat
must be machined.
Adjust the liner to the correct height using a
shim. Shims are available in thicknesses of
0.20 mm, 0.30 mm and 0.40 mm.
If the cylinder liner height should be increased
less than e.g. 0.20 mm, machine the bearing seat
until the liner height including shim is correct.
IMPORTANT! If a shim is used to adjust the
liner height, the cylinder liner seat must always
be machined.
Tolerances for liner height
Lowest permissible cylinder liner height
before machining
0.15 mm
Permissible cylinder liner height on
engines with machined liner seats
0.20-0.30 mm
Desired measurement when machining 0.25 mm
Example of calculation of cutting depth
Height required 0.25 mm
Current cylinder liner height 0.14 mm
Increase in cylinder height = 0.25-0.14 0.11 mm
Shim thickness 0.2 mm
Material to be removed = 0.2-0.11 0.09 mm
