V-drive
In all installations with a down angle propeller shaft
there will be a lifting force transmitted from the propel-
ler shaft. In an installation of an engine with a V-drive
this force could be higher than that from the weight of
the engine and gear box.
This will create a lifting force to the engine mounts fit-
ted at the same end as the gear box. Therefore all en-
gines with a close coupled V-drive must be equipped
with mounts at the reverse gear end which are de-
signed for this type of application.
