Use of special milling tool 9551
Before grinding the cylinder liner seat, measure the
cylinder liner height in order to calculate the compen-
sation space for removed material.
1.
Use the dial indicator and note the measurement.
Assume, for example, that the seat has sunk a bit
and is 0.12 mm.
2.
Remove the cylinder liner. Establish the damage.
As an example of how to estimate this, let us as-
sume that a milling of 0.20 mm would be suitable.
3.
Before setting up the milling tool, roughen up the
liner seat with emery paper.
4.
Fit the used O-ring at the lower cylinder liner seal
to ensure accurate centering of the milling tool.
5.
Remove the small fillet in the bottom of the cylin-
der liner seat, if this has not been done already.
6.
Use milling tool 9551, which is bolted onto the
cylinder block. Use suitable flat washers under the
bolt heads. Make sure the feed screw does not
press against the tool and that the washer under the
feed screw is clean and greased.
7.
Set up the dial indicator as shown in the Fig. Screw
down the feed sleeve to exert light pressure on the
milling head. Zero-set the dial indicator.
