Inspect the oil level in the hole for the oil plug,
filling and inspection .
The oil should reach all the way up to the extern-
al edge of the thread for the
oil plug, filling and
inspection .
Note
If needed, use a clean, narrow object, for ex-
ample an oil stick or a cable tie, to gently poke
the oil surface. This will avoid surface tension
from stopping air to enter into the gearbox.
