4.5.1.5 Oil filter replacement
Remove engine cowlings. Unscrew the elbow on the left front (as viewed in flight direction)
exhaust pipe using nut wrench size 12. Loose a clamp of that pip on the exhaust muffler using
wrench 13. Disconnect the elbow from the engine and turn the exhaust pipe slightly to move it
from the oil filter. Replace oil filter by a new one. See Maintenance Manual (Line Maintenance) for
ROTAX Engine Type 912 Series for replacement instructions. Connect the elbow to the engine
and tighten the nuts slightly by fingers. Set exhaust pipe clearance from the radiator hose and oil
filter. Clearance from the radiator hose must be min. 0.8 in (20 mm) and approximately 0.2 in (5
mm) from oil filter. When clearances are set, tighten the elbow and clamp. Re-install the engine
cowlings after oil re-filling.
