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.
