HYDRAULIC CONNECTIONS
Refer to the Tractor Manual when connecting hydraulic hoses to the tractor hydraulic
system. Numerous precautions should be taken due to the possibility of a pressure buildup
within the hydraulic circuit. Relieve the pressure before opening or entering the circuit.
FLUID ESCAPING UNDER PRESSURE CAN PENETRATE THE SKIN CAUSING
SERIOUS INJURY. Ensure that hose fittings are secure before pressurizing the hydraulic
systems.
Once drivelines are installed, DO NOT start the tractor (which will turn the pumps) unless
both power circuits are filled with the specified hydraulic fluid. Running pumps without oil
will cause non-warrantable damage.
It is important that pipe thread sealant be used only on solid connections of pipe thread; never on connections
between swivel fittings and solid male pipe threads or on straight thread "O" ring fittings. Use the pipe thread
sealant supplied. Do not substitute with some other type of sealant, i.e., 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 a outer 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.
The VERSA PRO 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 the 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 fittings or hoses. KEEP THE INTERIOR
OF ALL HYDRAULIC COMPONENTS SURGICALLY CLEAN. Inspect the inside diameter of each hose before
assembly. Ensure that no obstruction is present. Dirt, sand, dust, etc., are abrasive and once in the system
can cause immediate or early failure.
NOTE: Do not strap hoses together until all hoses and wiring are connected. Hoses and wiring should be
routed so they do not lay on moving parts, too close to sharp edges, or near excessive heat.
