- The cylinder liner should be slightly above the
surface of the cylinder block.
- The difference between the two measurements
on the same liner may be up to a maximum of
0.035 mm.
- Cylinder liner height D (=A-B) above the
block should be 0.27-0.33 mm.
Adjusting cylinder liner height
- Check and, if necessary, adjust the entire cylin-
der bank at the same time.
- The liner mating surface in the block must be
clean and in perfect condition. Affix tape
(adhesive side out) over the oilway holes in the
crankshaft. Place a cloth in the cylinder block
to collect swarf.
- If the surface is damaged it must be machined
using tool 587 272.
- After the liner’s mating surface in the block has
been machined, a shim must be fitted to pro-
vide correct liner height.
- Try to aim for the least possible amount of
machining so that the thinnest possible shim
can be used. Shims are available in the follow-
ing thicknesses: 0.20, 0.25, 0.30, 0.40, 0.50 and
0.75 mm.
- Remove any burrs and measure the thickness
of the shims using a micrometer. Only use one
shim, i.e. a thick shim, instead of several thin
ones.
- Try to set liner height close to the upper limit
of 0.33 mm.
