PRODUCT MERCHANDISING MANUAL - Hydraulic Lift

MONROE HYDRAULIC LIFT

There are three basic elements that make the Willys Jeep the "WORLD'S MOST USEFUL VEHICLE."  They are:

A) Four'-Wheel Drive

B) Power Take-Off

C) Hydraulic Lift

These three factors have rendered the Jeep unique in its field. At the same time they have made it the object of great envy and imitation. However, to this date, no imitation has succeeded in completely integrating these elements to the point of Jeep perfection so highly valued by Jeep owners the world over.

Experience has proven that the dealers and distributors whose sales personnel have developed an understanding of these elements seldom have any difficulty in dominating the market for 4-WD vehicles in their territory.

The Monroe Hydraulic Lift, especially designed for the Universal Jeep, provides a modern 2-way hydraulic lift system to position standard three point hitch implements. This lift does not interfere with the rear power take-off, belt pulley, sta-bar hitch or other standard Jeep accessories.  As a separate unit, the pump, reservoir and control valve may be used to supply hydraulic pressure to equipment not requiring the rear lift mechanism, e.g., the front-mounted snowplow.  Installed on the Universal Jeep, the hydraulic lift makes this vehicle ideal for many farm, municipal and industrial purposes and primarily one which has 365 work days every year. In providing for the simple hitching or unhitching of implements designed for a three-point hitch, the Monroe Hydraulic Lift has many features never before found in similar equipment.

PRINCIPAL PARTS

There are three major elements in the Monroe Hydraulic Lift:

1) The Hydraulic Pump, Pump Drive and Mounting Bracket attached to the front of the Jeep engine,

2) The Fluid Reservoir and Control Valve Assembly mounted between the front seats, and,

3) A completely sealed and protected Lift Assembly that is attached with only three bolts in the back of the Jeep body to the chassis.

Large capacity hydraulic lines permanently connect the pump to the Reservoir and Control Valve Assembly, detachable connections are used on the lines between the Reservoir and the Hydraulic Life Assembly.

OPERATING ADVANTAGES

All controls can be reached from the driver's seat. The down pressure is adjustable, permitting 500 pounds of extra weight to be placed on the implement.  Working depths are easily regulated, Tilt and Leveling are easily controlled providing excellent following and trailing movements of implements in hilly or rough terrain. Fast, positive operation in all conditions can be expected.

INSTALLATION ON JEEP

The lift assembly is attached to the Jeep body by three cap screws. The tow links are attached by easily removable pins. Hydraulic lines between the tank and lift can be quickly detached so that the life mechanism can be removed from the Jeep by one man in a very few minutes. This clears the Jeep body and permits the vehicle to be used for other purposes.

IMPLEMENT ATTACHMENT

All equipment using the three-point linkage system may be easily and quickly attached or detached by one man. Ball sockets at seven points as sure proper alignment and movement under all conditions of operation.  A rack is provided on the upper line for use with towed implements.

FINGER TOUCH CONTROLS

To raise, lock or lower the Hydraulic Lift and attached implement is very simple. By setting the control lever in the forward position the implement attached to the Hydraulic Lift drops slowly until it touches the ground.  The implement then floats in this position or digs into the ground depending on the action of the implement and its depth controls. For example, the plow has a natural tendency to dig itself into the earth, but the depth of its furrow is controlled by a depth control wheel mounted on the plow itself.

If the control lever is set in the rear position, the implement raises to the maximum height permitted by the hydraulic arms.

Setting the control lever vertically locks the implement in whatever position it is in.

A discussion of the oil flow in the hydraulic system will lead to a better understanding of the functioning of the Monroe Hydraulic Lift.

The convenient lever located at the driver's right-hand controls the oil flow of the hydraulic system. When the lever is moved completely forward the oil flows from the forward part of the piston cylinder through the valve to the pump at the front of the engine.

The pump then forces the oil toward the reservoir with a considerable amount of this oil passing to the rear of the lift cylinder piston to help balance the pressure on it. The oil is forced out of the front of the piston cylinder by the weight of the implement on the hydraulic arms. The down travel of the implement, governed by its own weight, is arrested when the implement reaches the ground.

If the control lever is moved completely back the oil flows from the pump through the control valve to the front of the hydraulic piston.  This forces the piston back thus raising the top ball joints of the lift arms and raising the implement.

To lock an implement in any given position set the control lever in a position just a bit forward of the perfect vertical. You can locate this point exactly by listening for a change in the sound of the oil flow and feeling the lever slip into position. This blocks the oil circuit and prevents the oil from flowing into or out of either chamber of the piston cylinder. This locks the piston in place and maintains the position of the top ball joint holding the implement in the desired position.

A special feature incorporated into the Monroe Control Valve is the added down pressure available to the user.  By turning the knurled Knob at the top of the valve clockwise, up to 500 pounds per square inch of extra down pressure is achieved. This blocks the orifice through which the excess oil drained into the reservoir when the lever was set in the forward position. Down pressure is adjustable in units of about 43 pounds per square inch for each clockwise quarter-turn.

Although the hydraulic lift arms are square with the bed of the Jeep to which the hydraulic lift is attached, adjustment of the angle of the implement is possible with the tilt and leveling regulator located directly behind the driver's seat on the left rear lift arm. Clockwise rotation lowers and counter-clockwise rotation of the crank raises the arm and consequently the side of the implement attached to it.

The next chapter deals with the Hydraulic Lift attachments available through Willys Motors, Inc. Study these applications. Find those which best apply to your territory but remember:

ANY THREE-POINT HITCH EQUIPMENT already owned by your prospective client is still usable. Make him understand that by purchasing a Jeep with the Monroe Hydraulic Lift he is not losing all the money he has invested in equipment previously purchased.

THE SALE OF A MONROE HYDRAULIC LIFT REPRESENTS DOUBLE THE RETURN ON INVESTMENT BY A DEALER IN NET PROFITS AS COMPARED TO THE SALE OF A NEW CAR. MOST IMPORTANT TO YOUR CUSTOMER IS THE FACT THAT THE MONROE HYDRAULIC LIFT REPRESENTS AN INFINITELY GREATER RETURN ON HIS INVESTMENT IN USEFULNESS AND VERSATILITY.
