Operating medium: Heavy fuel and distillate fuel
Inspection:
- Of one cylinder liner after 15,000 h
- Of all cylinder liners every 30,000 h
- Of the cylinder liner after removing the piston. Before
and after fitting the cylinder liner.
Tools:
Gauge ruler for cylinder liners W1 2.9216-022
Precision inside micrometer W2 * 1.9425-300
* not illustrated , special tool
Sequence of operation:
1. Check the cylinder liner.
Note:
Extreme wear can occur on the cylinder liners which has
to be evaluated and measured depending on the
operating time and operating conditions (fig. 3).
1.1 Dismantle the calibrating ring (02.05.50.nn) and extract
the piston (02.06.01.nn).
1.2 Clean the inside of the cylinder liner. The crankcase must
be properly covered when doing this.
1.3 Measure the cylinder liner at the measuring points
specified by the gauge ruler (fig. 1/W1) and the table
(fig. 2) longitudinally, transversally and 2 x diagonally to
the engine axis by means of the precision inside
micrometer (W2).
