3EATON Duraforce HMV Conversion Procedures Manual E-MOPI-TM006-E July 2012

This manual will provide you with information and procedures for general conversions of Eaton® DuraForce™ HMV Variable Displacement Open and Closed Loop Hydraulic Motors. Procedures outlined in this manual will allow you to be more flexible with your inventory and better service your customers. To ensure accuracy of conversion and prevent part loss or damage, certain components or subassemblies are disassembled, inspected, and reassembled when removed from the motor.

Training

You have been provided information on the conversion of DuraForce products. Proper application of the information requires specific training and may require use of specialized tooling and equipment. All requests for training must be coordinated through your Eaton Account Manager. He can also provide you price and availability of any specialized tooling. If you choose to proceed with the conversion of the DuraForce products absent the necessary training and/or these specialized tools, you do so at your risk.

Eaton will accept no claim for warranty resulting from deficiencies in the conversion. Please refer to the Eaton literature web site for warranty information at www.eaton.com/hydraulics/warranty.

Labeling Converted Units

All units that have been converted must retain the original Eaton label and have a second Eaton label placed on the unit. This second label at a minimum must state

Converted Eaton Model Code # (Final Eaton model code of the converted unit)

Conversion done by (Name of your company)

Conversion Parts

All requests for specific conversion part information should be addressed to your Eaton account representative. Additional information can be found through your Eaton customer connect portal. All requests or inquiries must be accompanied by the complete model and serial number of the base unit you want to convert.

Cleanliness

Cleanliness is extremely important when repairing a hydrostatic pump or motor. Before disconnecting the lines, clean foreign material from exterior of unit. Work in a clean area. Clean all metal parts in clean solvent. Blow parts dry with air. Don’t wipe parts with cloth or paper towel, because lint or other matter could cause damage. Check all mating surfaces. Replace any parts that have scratches or burrs that could cause leakage. Don’t use coarse grit paper, files or grinders on parts.

Environmental Concerns

Protection of the natural fundamentals of life is one of our predominant tasks. We are continuously improving the protection of the environment as far as applications are concerned. We encourage you to contribute your share to comply with this demand. In connection with work to be performed, the environmental regulations of the machine manufacturer must be respected.

In general:

• Greases and oils which cannot be used any more have to be collected. They are normally a threat to water reserves and must be kept away from the environment.

• Adhere to national and local regulations for waste disposal.

Seals

A good conversion policy is to replace all old seals with new seals whenever units are disassembled. This avoids potential damage during seal removal. Lubricate seals with petroleum jelly. Use only clean and recommended oil when assembling unit. Information on recommended filters and fluids can be found in the Operational Parameters section.

Torque

All torque specifications are for lubricated threads. Bolts for gasketed surfaces should be checked for proper torque.

Use the small needle-nose pliers to remove the control sleeve as shown here.

Important

The control sleeve should slide out easily. Care must be taken during this step to prevent damages on the control sleeve’s running surface.

The control spring should come out with the control sleeve. If for some reason the control spring remains inside the housing, it must be removed using the magnet.

Place the removed control sleeve / control spring with the removed control block and do not reuse it.

Exchanging Infinitely Variable ControlsProcedure to Exchange Motor Controls

Position the motor as shown here (with work ports down), then remove the four control mounting bolts as shown here.

Note


1Use the magnet to remove the control spool as shown here.3

Remove the control as shown here.2 4Note

There are two o-rings between the control and the HMV rear head. Make sure that both of them are removed with the control.

Note

There is a small washer between the control spool and the control sleeve. This washer may come out with the spool when magnet is used; if not, insure that the washer is removed before proceeding to next step. Do not lose this washer.

As seen here, the control spool is not a symmetrical object. The small end of the spool is directed towards the motor’s rear head.



A better view of the control sleeve and control spring after it has been removed.

Note


5Use a long screw driver to make sure that follow-up linkage is centered inside the control cavity.7

After the control sleeve / control spring has been removed, the follow-up linkage will be exposed as shown here.

6 Install the new control sleeve / control spring into the control cavity on the motor rear head. The control sleeve should slide into position very easily.

In case of any resistance, remove the control sleeve and reposition the control spring and follow-up linkage.

Inspect the o-ring on the mounting surface of the control.14


Maximum Displacement Adjustment ProcedureSet Up and Procedure

Note #1

The table at right illustrates the maximum displacements and allowable rotational speeds for those displacements for the HMV motors. The HMV motors should NOT be operated at higher speeds if these maximum displacement settings are used. If higher rotational speeds are required for your application, you must consult Eaton Engineering for the allowable maximum displacement setting.

Note #2

To insure the proper operation of the motor, you must provide supply-pressure into port "E" between 290-580 psi. If the HMV has the configuration where this supply-pressure is provided internally (via the case-flushing shuttle), then ignore this note.

Note #3

The HMV motor automatically defaults to maximum displacement and will remain at maximum displacement unless supplied with an external pressure or power supply to force it to destroke. For a "hydraulically" controlled HMV motor, control pressure is typically supplied to port "X" of the motor to destroke it. For an "electrically" controlled HMV motor, current is typically supplied to the motor solenoid to destroke it. When performing this procedure, make sure that no external pressure or power supply is supplied to the HMV motor to insure that the motor remains at maximum displacement.

Note #4

The HMV motor with “E6” and “H6” controls automatically default to minimum displacement unless:

a. For H6 Infinitely Variable Control, supply a minimum of 205 psi control pressure into port "X".

b. For 12V E6 Electric Infinitely Variable Control, You provide a minimum of 720 mA to the solenoid.

c. For 24V E6 Electric Infinitely Variable Control, You provide a minimum of 360 mA tothe solenoid.

Procedure for Adjusting the HMV Maximum Displacement

Start the prime mover and adjust it to operating speed.

Actuate the HMV per the requirements stated in "Note #3" and “Note #4”.

To Adjust the Motor Maximum Displacement:

a. Hold the adjustment stud stationary with the 6mm Allen Wrench.

b. Loosen the seal nut with the 19mm wrench.

c. Turn the adjustment stud IN to decrease the maximum displacement or turn it OUT to increase the maximum displacement.

d. Once the desired maximum displacement has been acquired, hold the adjustment stud stationary with the 6mm Allen wrench and tighten the seal nut with the 19mm wrench. The proper torque for the seal nut is 60 N-m (44 ft-lb).

Note #3

The HMV motor automatically defaults to maximum displacement unless:

a. (For Hydraulic Infinitely Variable Control) You supply a minimum of 205 psi control pressure into port "X".

b. (For 2-Position Hydraulic Control) You supply a minimum of 205 psi control pressure into port "X".

c. (For 10VDC Electric Infinitely Variable Control) You provide a minimum of 1460 mA to the solenoid.

d. (For 12VDC 2-Position Electric Control) You provide a minimum of 720 mA to the solenoid.

e. (For 24VDC 2-Position Electric control) You provide a minimum of 360 mA to the solenoid.

Under the above conditions, the HMV motor will be forced to minimum displacement.

Note #4

For HMV motor with “E6” or “H6” controls, the motor automatically defualts to Minimum Displacement.

Procedure for Adjusting the HMV Maximum Displacement

Start the prime mover and adjust it to operating speed.

Depending on the type of control on your HMV, refer to "note #3" and “note #4” above to force the motor to minimum displacement.

To Adjust the Motor Minimum Displacement: a. Hold the adjustment stud stationary with the 6mm Allen Wrench. b. Loosen the seal nut with the 19mm wrench. c. Turn the adjustment stud IN to increase the minimum displacement or turn it OUT to decrease the minimum displacement.

Once the desired minimum displacement has been acquired, hold the adjustment stud stationary with the 6mm Allen wrench and tighten the seal nut with the 19mm wrench. The proper torque for the seal nut is 60 N-m (44 ft-lb).

Purity of Fluid Lower than 18/ 16/ 13 in accordance with ISO 4406

Filtration

For Reliable Proper Function and Long Service Life 18/16/13 in accordance with ISO 4406 or betterMinimum Requirements 20/18/15 in accordance with ISO 4406Commissioning The minimum purity requirement for the hydraulic oil is based on the most sensitive

system component. For commissioning we recommend a filtration in order to achieve the required purity.

Filing in Operation of Hydraulic Systems The required purity of the hydraulic oil must be ensured during filling or topping up. When drums, canisters or large-capacity tanks are used the oil generally has to be filtered. We recommend the implementation of suitable measures (e.g. filters) to ensure that the required minimum purity of the oil is also achieved during operation

Operational parameters. Filtration

In order to guarantee long-term proper function and high efficiency of the hydraulic pumps the

cleanliness level of the lubricant must comply with the following criteria according to

Eaton Hydraulic Fluid Recommendation 03-401-2010. Maintaining the recommended cleanliness

level can extend the service life of the hydraulic system significantly.

Operational ParametersPressure Fluids

In order to ensure the functional performance and high efficiency of the hydraulic motors the viscosity and purity of the operating fluid should meet the different operational requirements. Eaton recommends using only hydraulic fluids which are confirmed by the manufacturer as suitable for use in high pressure hydraulic installations or approved by the original equipment manufacturer.

• Mineral oil HLP to DIN 51 524-2

• Biodegradable fluids in accordance with ISO 15 380 on request

• Other pressure fluids on request

Recommended Viscosity Ranges

Viscosity Recommendations

In order to be able to select the right hydraulic fluid it is necessary to know the working temperature in the hydraulic circuit. The hydraulic fluid should be selected such that its optimum viscosity is within

the working temperature range (see tables).

The temperature should not exceed 90°C (194°F) in any part of the system. Due to pressure and speed influences the

leakage fluid temperature is always higher than the circuit temperature. Please contact Eaton if the stated conditions cannot be met in special circumstances.

Working Temperature Viscosity Class

Temperature [mm²/s] = [cSt] at 40°C (104°F)

Approx. 30 to 40°C (86 to 104°F) 22Approx. 40 to 60°C (104 to 140°F) 32Approx. 60 to 80°C (140 to 176°F) 46 or 68
