Installation of the Update of the Swing Drive System for the 5130B Excavator{5057, 5058, 5059, 5459} Caterpillar

Excavator:

5130B (S/N: 4CS1-183)

Introduction

This Special Instruction explains the procedure for the update of the Swing Drive System for the 5130B Excavator.

The purpose of updating the Swing Drive System is to extend the service life of the swing drives and the swing gear. This is accomplished through closer management of the pilot circuit and the swing hydraulic circuit utilizing updated VIMS monitoring and increasing the Machine Control responsibilities. This enhances the system to match deceleration with acceleration torque providing smooth operation and controlled loading to the swing drives. Travel induced loading to the swing drives is substantially reduced by releasing the swing brakes any time the machine is tramming. The pilot system is also enhanced to provide a more stable pilot pressure throughout the entire operating RPM and temperature ranges.

AVSpare recommends the installation of new O-rings and seals when existing parts are removed and installed.

The photos and illustrations are for illustrative purposes. The illustrations may not be drawn to scale. THE PHOTOS MAY NOT BE IN THE ACTUAL SEQUENCE OF THE INSTALLATION PROCEDURE.

Pressure Adjustments for the 5130B Excavator

Show/hide table

Hydraulic oil pressure can remain in the hydraulic oil system on this machine after the engine and pump have been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic systems. To prevent possible injury, refer to the procedure in Testing and Adjusting Manual, "Release of Pressure in the Hydraulic System". When possible, the bucket must always be lowered to the ground before service is started. When it is necessary for the boom to be in the raised position while tests or adjustments are done, be sure that the boom, stick and bucket have correct support. Be sure the swing parking brakes and the travel parking brakes are on and the brake release lines are disconnected and plugged. Always move the machine to a location away from the travel of other machines. Be sure that other personnel are not near the machine when the engine is running and tests or adjustments are being made.

Show/hide table



Illustration 78	g00806827

1. Remove the inlet hose and the outlet hose from the swing solenoid valve. Use union (67) and two O-ring seals (37) to connect the hoses together.

2. Start the engine.

3. Warm the oil to a minimum temperature of 50 °C (122 °F). Refer to the Testing and Adjusting, "General Information" for the proper procedure for warming the hydraulic oil.

4. Set the throttle switch to position 10.

5. Slowly actuate the swing control to the full left position or the full right position in order to stall the swing motors against the swing brakes. This checks the acceleration pressure setting of the swing dual pressure relief valve. Record the pressure that is indicated by the gauge that is installed on the pressure tap. The acceleration pressure setting for the swing system should be 35000 ± 1000 kPa (5080 ± 145 psi).

6. Remove the cover. Add or remove shims in order to adjust the pressure. Each 0.13 mm (0.005 inch) shim will change the pressure setting by 210 kPa (30.5 psi).

7. Reconnect the inlet hose and the outlet hose to the correct positions on the solenoid.

4. Set the throttle switch to position 10.

5. Slowly actuate the swing control to the full left position or the full right position in order to stall the swing motors against the swing brakes. This checks the deceleration pressure setting of the swing dual pressure relief valve. Record the pressure that is indicated by the gauge that is installed on the pressure tap. The swing deceleration pressure should be 28500 ± 1000 kPa (4135 ± 145 psi).

6. Remove the cover. Add or remove shims in order to adjust the pressure. Each 0.13 mm (0.005 inch) shim will change the pressure setting by 210 kPa (30.5 psi).

   Note: After completion of the steps for adjustment of the swing dual pressure relief valve, reconnect the connector between the wiring harness and the solenoid valve. Reset the adjustment of the high pressure cut for the swing pump. Also reconnect the brake release line to the swing parking brake.

Troubleshooting

Problem: All the software appears to have downloaded with no problem, but when I go into ET, the machine control shows blank.

Solution: The software is probably uploaded properly, but if the machine control shows blank when using ET, it is because the attachment code has not been entered through the VIMS key pad on the dash. Refer to Systems Operation, SENR6059, "Attachment Code - Configure".

Problem: The machine starts to swing, but then slows down almost to a stop.

Solution: The 6T-6552 Valve Manifold is probably installed upside-down. Make sure that the left hand mounting bolt is facing the front of the machine, and the 152-8345 Solenoid Valve Gp is pointing toward the rear. If it is not mounted correctly, it will be necessary to reposition the 183-6273 Block that the manifold bolts to.

Problem: The swing cycle time is very slow.

Solution: If the 6T-6552 Valve Manifold is correct, it may be necessary to thoroughly purge the swing signal line that connects the swing control valve to the swing pump compensator. If this does not improve the swing speed, remove 198-4707 Shuttle Valve and test to see if the swing times improve. If the swing time improves substantially, replace the 198-4707 Shuttle Valve .

Problem: There is an annoying hydraulic noise in/under the cab that wasn't there before.

Solution: Remove 192-1598 Pressure Reducing Valve . Clean the valve and reinstall the valve. Tighten the valve to a torque of 108 N·m (80 lb ft). Set the pilot pressures. If the noise persists, replace 192-1598 Pressure Reducing Valve .

Problem: After the swing strategy update is completed, the swing system won't shift to the high (accel) pressure.

Probable Cause: Open circuit on the swing pressure solenoid. Check the ET/VIMS diagnostic list.

Probable Cause: Using VIMS, check for swing speed and swing solenoid status. When you call for swing, the swing speed should increase and as the swing speed increases, the status of the swing solenoid should change.

If there is no swing parameter, double check that the proper src. and cnf. files are loaded into VIMS, make sure the proper software has been loaded for the MAC 14, and double check that the attachment code has been properly entered in VIMS.

Probable Cause: If a swing speed reading is available, but does not change as the machine swings, check for a bad swing speed sensor, or possible water contamination. The MAC 14 will not change the status of the swing solenoid until acceleration is sensed.

If swing speed increases, but pressure does not shift to the accel setting, check to make sure the swing solenoid changes status. If a status change is apparent, but there is still no accel pressure, place a pressure gauge between the solenoid manifold and the swing relief valve to verify existence of pilot pressure as the solenoid is activated.
