ASSEMBLY
ATTACHMENT OF HYDRAULIC HOSES
It is important that pipe thread sealant be used only on pipe threads; never on 37 degree flared fitting or on
straight thread “O” ring fittings. Use the pipe thread sealant supplied. Do not substitute with some other type of
sealant, such as, teflon tape, paint, shellac, etc.
Hoses supplied have two types of fittings; solid or swivel. Some hoses have solid fittings on both ends; others
have a solid fitting and a swivel fitting. Hoses with two solid fittings will fit into either an internal solid thread or a
swivel adapter union. When installing either type hose, solid fittings must be installed first, then install the
swivel end of the hose or fitting.
The hydraulic system incorporates three basic types of hydraulic fittings:
a. Standard pipe (NPT or NPTF) thread fittings. This type requires a small amount of evenly-applied sealant.
b. Swivel fittings. This type does not require any sealant on swivel end because it seals against an internal
flare.
c. “O” ring fittings. This type does not require any sealant on the “O” ring end of the fitting.
It is extremely important to avoid getting pipe thread sealant inside the fitting or hoses. KEEP THE INTERIOR
OF ALL HYDRAULIC COMPONENTS CLEAN. Inspect the inside diameter of each hose before assembly.
Make certain that no obstruction is present. Dirt, sand, dust, etc. are abrasive and once in the system can
cause immediate or early failure.
HOSE CONNECTIONS ELECTRONIC
A break-away valve for the swing cylinder must be
mounted to the top of a valve mount plate on the
Main Frame (7) with 2 - 1/4" x 2 3/4" bolts (1) and
fastened with 1/4" locknuts (2). Attach the 90°
elbows (4) to the "A", "B", "C1", and "C2" ports of
the breakaway valve. Attach the straight adapter
(6) to the "T" port of the breakaway valve. A relief
hose is then connected to the other 90 degree
elbow (5) which is connected to a straight adapter
(6). The other end of this hose is connected to a
filler tube on the tractor hydraulic tank by a special
adapter.
NOTE: When connecting the hose from the
breakaway valve to the tractor hydraulic filler tube,
there are two types of adapter depending on the
size of the filler tube. A small tube will require a
small adapter P/N 00765736. A large filler tube will
use P/N 00765735. To install adapter, insert it into
the filler tube, and tap it lightly until it stops. Screw
the elbow into the adapter, and connect the hose
from the breakaway valve. Alternately, for a more
reliable connection, this hose can be connected to a
"zero back pressure" return port on the tractor.
Consult your tractor's owners manual and/or tractor
dealer for information regarding this type of
connection.
