Plumbing Connections - Mile Marker H Series Installation And Operator's Manual

Please refer to illustration. Keep all hoses away from any areas where heat may be considered too extreme (such as exhaust manifold or turbo).
Lines should not to be allowed to rub on any abrasive or vibrating surfaces. In some applications, 90° fittings on the solenoid valve are nec-
essary to make hose mounting more flexible. After plumbing has been laid out on vehicle, install O-ring fittings supplied to valve. Torque tight.
Do not over tighten any fittings. Install O-ring fittings on winch motor. Torque tight. Connect hose number two to port number two on the valve
assembly. Attach the other end of hose number 2 to any port on winch. Connect hose number four to port number four on valve assembly and
attach the other end of number four to the other port on winch. Torque both hoses (both sides) ¼ turn past finger tight. See (Fig. 2).
NOTE: Make sure and re-use any 0-rings or seals from OEM tube fittings!
Disconnect original (OEM) high pressure line from the power steering pump to the steering gearbox. If your truck has hydroboost brakes, you
will remove the high pressure line from the hydroboost to the steering box. Note: Low pressure line will normally have a hose clamp. See (Fig. 3).
CAUTION: Fluid will be lost from the system.
Attach any O-ring or seal from vehicle's original tube fitting to tube fitting #3. Connect tube fitting #3 to power steering pump. Torque to vehicle
factory specifications. Connect hose #3 to tube fitting #3. Torque¼ turn past finger tight. Attach other end of hose #3 to port #3 on solenoid
valve. Torque¼ turn past finger tight. Attach any O-ring or seal from vehicle's original tube fitting to tube fitting #1. Connect tube fitting #1 to
steering gearbox. Torque to vehicle factory specification. Attach hose #1 to tube fitting #1. Torque ¼ turn past finger tight. Connect the other
end of hose #1 on Solenoid valve. Torque ¼ turn past finger tight. See (Fig. 2).
If your application is supplied with an added cooler, remove (OEM) low pressure line from reservoir. Attach hose #5 to existing return line using
male to male coupler and hose clamps supplied. Tighten hose clamps. Connect the other side of hose #5 to cooler supplied with hose clamp.
Tighten hose clamp. Attach hose #6 to cooler and reservoir with hose clamps. Tighten hose clamps. Check fluid level. Replace lost fluid to sys-
tem. System will need to be purged. Lift pin on free spool release on winch. Manually pull approximately 10 feet of cable off winch drum. Lock
free spool pin back down. Add fluid until full. Start engine. Power winch cable out five feet. Shut off engine. Check fluid level. Add fluid until full
if necessary. Start engine. Power winch cable into desired position. Turn the vehicle's front wheels from lock to lock position five times (all the
way to the right and then all the way to the left). This will aid in bleeding out any air that may have gotten into the system.
NOTE: If the hand control unit is working backwards, simply reverse the black and white wire connectors on the valve assembly.
