Hydraulic Hose Installation

WARNING
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
NOTE
On most tractors this can be done by putting the valve
controls in the float position before the engine is stopped.
Tightening Procedure For JIC 37° Swivel
Female Nuts
1. Check flare and seat for defects.
2. Lubricate the connection.
3. Install hoses without twists.
4. Hand tighten until connection bottoms.
5. Using 2 wrenches to prevent twisting, rotate the
swivel nut 2 wrench flats (1/3 turn).
6. For reassembly, follow the same procedure but
tighten only 1 wrench flat (1/6 turn).
Tightening Procedure For Swivel O-ring
Fittings
1. Lubricate o-ring and install the fitting until the metal
washer that backs up the o-ring contacts the face of
the boss.
2. Orient the fitting by turning counterclockwise up to 1
turn.
3. Tighten the lock nut using 50-60 foot pounds torque.
NOTE
As you assemble hoses to fittings leave hose ends loose
enough on the fittings so that they can pivot as the hose
is being securely clamped to the hitch.
Use the Hydraulic Schematic as a reference: See
Figure 2-9.
1. Lube all o-ring connections. Install the hydraulic
fittings. See Figures 2-10 and 2-11.
2. Starting at the Rear Hitch bulkhead plate just above
the Caster Wheel, Install the Hydraulic Hoses. See
Figures 2-10 and 2-11.
3. To prevent excess wear, wrap the two hoses near the
spring cushion with Hose Wrap. See Figure 2-10.
4. Secure the hoses in place with Hose Clamps and
Cable Ties provided.
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate the
skin causing serious injury. Use a piece of
cardboard, rather than your hands, to search for
suspected leaks. Wear protective gloves & safety
glasses or goggles when working with hydraulic
systems.
