Engine Crankcase Breather
The engine uses a closed type breather (see
) with the breather line attached to the cylinder head cover.
It is not necessary to disassemble valve style elements for cleaning. However, the bleed hole should be checked
for obstructions. Check once a year or at every 4,000 hours maintenance interval, whichever comes first.
