2. Cleaning the scavenge air receiver
Cleaning and checking of the scavenge air receiver must always be carried out
after a piston overhaul. The inside of the scavenge air receiver has to be cleaned at
regular intervals.
At these opportunities check whether drains 10 are not clogged (Fig. ’A’).
During a major overhaul relief valve 9 must be checked. The valve is set to an
opening pressure of 4.5
"
0.2 bar.
Remark: Do not open the relief valve with disc springs! In case of any damages or
malfunctions please contact the manufacturer or Wärtsilä Switzerland Ltd.
