If tractor is equipped with power beyond, then
use the couplers as shown for case drain and
motor return.
If tractor is not equipped with power beyond,
then plugs need to be removed and couplers
need to be installed on the valve assembly as
shown. Order and install the following couplers
from a Case-IH and/or New Holland dealership
to add case drain and motor return:
Case Drain Coupler 380739A1
(flush face)
Motor Return Coupler 298291A1
The load sensing plug must be installed or
tractor oil will overheat and damage to the
pump can occur. The top plug must be
removed to gain access to the load sensing
plug. The load sensing plug is an internal plug
in the passage between the power beyond
pressure port and the load sense port.
IMPORTANT: ALWAYS connect case drain first,
motor return second, then pressure line to prevent
motor damage. ALWAYS disconnect pressure
line first, motor return second, then case drain
last to prevent motor damage.
