1.1 Before Engine Start
1) Prepare the engine for start, see 0110−1.
2) Do a check of the condition of the piston rings.
3) Do a check of the condition of the cylinder liners from the piston underside and
for signs of condensation or leakage (if the engine has not started for some time).
4) Do a check of the scavenge air receiver and piston underside for contamination.
5) Make sure that the water separator is in a clean condition.
6) Make sure that the scavenge air receiver drains are open and the high level
alarm operates correctly.
7) Set the cylinder lubricating oil feed rate for the applicable cylinders to
1.2 g/kWh.
8) In the remote control, get the USER PARAMETERS page (see 4002−3,
paragraph 1.1).
9) Set to off the VIT.
10) Set the FQS to 0.00 degree.
1.2 Running-in
1) Operate the engine for 24 hours.
2) Inspect the components for damage.
3) If damage occurs, find the cause and repair the fault.
4) If you have to replace parts of the piston running system, do Step 1 and Step 2
again.
5) Set the feed rate to 1.1 g/kWh.
6) Operate the engine for 24 hours.
7) Set the feed rate to 1.0 g/kWh.
8) Operate the engine for 24 hours.
9) Inspect the components for damage.
10) If damage occurs, find the cause and repair the fault.
11) If you have to replace parts of the piston running system, set the feed rate to
1.2 g/kWh and start with Step 1 again.
12) Set the feed rate to 0.9 g/kWh.
13) Do an empirical data collection, refer to 7218−3/A1 Feed Rate − Adjustment.
Note: It is usually necessary to inspect the condition of the running surfaces of
the piston rings and the cylinder liner to make an estimate of the
running-in status.
14) Do frequent checks to make sure that the cooling water quantity and temperature
is stable (differences in temperature are not permitted), (see 2124−1 Cylinder
Liner).
