Do not direct compressed air against skin. Use goggles or full face shield.
Use drycleaning solvent and remove dirt, grease, and oil from low-pressure cylinder head (97), high-pressure
cylinder head (103), low-pressure cylinder (100), high-pressure cylinder (106), inspection plates (109) and (112),
and piston pins (129) and (136). Dry with compressed air.
Magnaflux low-pressure cylinder head (97), high-pressure cylinder head (103), low-pressure cylinder (100), high-
pressure cylinder (106), inspection plates (109) and (112), and piston pins (129) and (136) and check that there
are no cracks. Replace damaged parts.
Clean, inspect, and repair crankshaft (166) by the following:
