Service
If any seal on the transmission shows signs
of
leaking, have the transmission looked at by a qualified Hurth
Servicing
Dealer. This problem, especially concerning the rear seal,
is
often contributed
to
an improper align-
ment of the transmission's coupling and the propeller shaft's coupling. Refer
to
the "Alignment of the
En-
gine" section
of
this manual, page
13.
NOTE: A leaking rear seal can also be the result
of
a blocked vent hole in the head of the
dipstick tube.
