Safety Warnings

Show/hide table

At operating temperature, the hydraulic tank is hot and under pressure. Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.

Show/hide table

Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak.

Introduction

Hose Machine

Illustration 3	g02638438
243-0765 Bench Model Hose Machine Mounted On A 157-6125 Stand .

The 243-0765 Bench Model Hose Machine is used for crimping permanent couplings onto Caterpillar hoses. It is designed to work with the 242-3567 Variable Crimp Die Group . It can crimp all current hoses in the Caterpillar line up to and including (-20), except for the XT-5 (-20). It cannot be used to assemble reusable couplings. Refer to the Hose Machine Capabilities Chart on the next page for a complete listing of hose types and sizes.

The hose machine is capable of using up to 68950 kPa (10,000 psi) of pressure. The portable power supply used with this hose machine must be equipped with a three-way valve which is set up for a single acting cylinder. A pendant (remote) electrical switch is recommended to control the hose machine.

Power Supply

Illustration 5	g02638464
161-5717 Power Supply And 162-1410 High-Pressure Hose Assembly .

A hydraulic power supply does not come with the bench model hose machine; one of the following three recommended power supplies can be used.

The 161-5717 Power Supply (115 VAC, 60 Hz, 1 phase) is the recommended power supply for this hose machine.

A 163-5309 Hydraulic Power Supply (230 VAC, 50 Hz, 1 phase) CE-compliant unit is available for hose machines being used in Europe.

High-Pressure Hose

A 162-1410 High-Pressure Hose Assembly is recommended for connecting the power supply to the hose machine. This 9.50 mm (.375 inch) ID hose is rated at 68950 kPa (10,000 psi) with a 4 to 1 safety factor.

The high-pressure hose is not part of the bench model hose machine and must be ordered separately.

Hose Machine Capability

Table provides the maximum size and type of hose that can be crimped with this hose machine using the variable crimp die bowl. Do not attempt to crimp hose couplings larger than recommended.

General Hose Assembly Guidelines

Producing high-quality hose assemblies requires observing the following general guidelines:

1. Cut the ends of the hose as square as possible.

2. Clean the inside of the hose to make sure that the coupling does not have dirt or other debris between the coupling and the inside of the hose. One of the 233-7191, 233-7192, or 233-7193, Hose Cleaning Groups is recommended for cleaning the hose.

   Refer to Special Instruction, NEHS0643, Using the 233-7191, 233-7192, and 233- 7193 Hose Cleaner Groups for more detailed instructions on cleaning hoses.

3. Insert the hose in the new coupling until it is aligned with the coupling insertion mark. Refer to the Insertion Depth Chart in Special Instruction, NEHS0768, "General Information for Hose Assembly", for additional information. Do not allow oil or grease on the hose or couplings. Only water is permitted as a lubricant when placing couplings onto hoses.

4. When crimping 1543 Air Conditioning Hose Couplings, carefully seat the coupling against the locating tab in the die group before crimping.

5. Sharp edges and burrs on crimped couplings can be removed with 80 grit emery paper or other suitable means.

6. To maintain the quality of each hose assembly, measure the finished crimp diameter to make sure that it meets the correct assembly specifications. Crimp diameters can be measured using a micrometer, calipers, or caliper measurement system.

   Note: Use Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567" (laminated chart) for crimp diameter specifications. Refer to Special Instruction, NEHS0768, "General Information for Hose Assembly" for additional information on measuring hose coupling crimp diameters. The parts in the following chart can be ordered individually and used to check the crimp diameter.

   136-0543	Paper Rolls (10)

7. Clean each hose after assembly.

   1. Tap both ends of the hose to remove any large particles.

   2. Use one of the 233-7191, 233-7192, or 233-7193, Hose Cleaning Groups to clean the inside diameter of the hose assembly. A cleaning projectile should be sent through each end of the hydraulic hose.

Note: Refer to Special Instruction, NEHS0643, Using the 233-7191, 233-7192, and 233- 7193 Hose Cleaner Groups for more detailed instructions on cleaning hoses.

Operation

Crimping Hose Couplings Using Caterpillar Dies

Illustration 13	g02638520

1. Select the appropriate die from the Die Groups Table 1 of this manual.

2. Set the variable die bowl to the correct "Bowl Setting" reference number found in Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567" or in this manual.

Show/hide table



Illustration 14	g02638537

3. Find the crimp length on Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567" and mark that length on the hose coupling.

6. Install the front pusher plate.

Show/hide table



Illustration 18	g02638600

7. Lower the pusher plate until it touches the top of the variable crimp die bowl.

8. Raise the pusher plate. Remove the hose assembly, and check the crimp diameter. Refer to Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567" for crimp diameter specifications.

9. If necessary, adjust the variable crimp die bowl to make the crimp diameter of the next hose assembly as close as possible to the specified crimp diameter. Write this new Bowl Setting number in the "Actual Setting" column of Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567". Using this new number should provide a more accurate crimp diameter the next time the die is used to crimp a hose coupling.

Crimping 1543 Air Conditioning Couplings

1543 Air Conditioning Couplings can be crimped using the variable die bowl by removing the 133-7362 Die Rest and using the appropriate die group. Refer to Special Instruction, NEEG3000, "Crimp Diameter Chart for 242-3567" for the "Bowl Setting" and die group part number for the coupling being assembled.

For additional information, refer to Special Instruction, NEHS0749, "Crimping 1E-1543 Air Conditioning Hose and 1E-1028 Thermoplastic Hose ".

Maintenance

1. Clean all dirt and debris off the hose machine and counterbore of the die bowl.

2. Lubricate the variable crimp die bowl with 129-1939 Grease or equivalent.

Inspection

1. Inspect the variable crimp die bowl parts daily for damage or abnormal wear. Replace all worn or damaged parts immediately.

2. Inspect the hydraulic power supply and high-pressure hose. Make sure that the hose connections are tight and not leaking.

3. Make sure that the hydraulic cylinder is not leaking. A seal kit is available to repair the cylinder.
