* not available as figure
Note:
When lifting the cylinder head or when turning afterwards, the liner is always to be secured
with the hold-down in order to prevent the liner from becoming loose.
Attention:
Do not fall below minimum bending radius r = 120 mm of the high-pressure hoses. Only
use hydraulic oil as an operating material (see Section A4.05.08, “Operating materials”).
Store equipment protected against corrosion.
ĭ Safety note:
No parts of the body should be over the equipment which is under pressure. Secure
engine against unintentional starting.
Sequence of operations:
1. Mount liner holding device (W11) (02.06.01.nn). Turn the piston to firing TDC. Remove
cylinder head cover and pump room lining.
2. Drain cooling water completely into a draining tank (connecting line: distributor line inlet/
