- Backhoe Loader:
- 416E (S/N: SHA116-UP)
Introduction
This special instruction outlines the basic procedures in order to install a ride control kit on a backhoe loader of the E series.
Ride control is an option on all backhoe loaders in the E series.
Ride control acts as a shock absorber to stabilize bucket movement as the backhoe loader is maneuvering. By dampening bucket movement, the machine is more stable especially when the bucket is carrying a load. More stability over rough terrain results in faster times. More stability also increases productivity.
Do not perform any of the procedures until you have read the information in this publication.
Also refer to the appropriate Parts Manual, Operation and Maintenance Manual, and Service Manual for your machine.
Required Parts
A machine with mechanical controls for the backhoe must use the 258-8352 Ride Control Installation Group .

Preparing the Machine for Servicing
- Park the machine on a level surface.
- Apply the service brake in order to stop the machine. Move the transmission control lever to the NEUTRAL position.
- Move the speed control lever to the LOW IDLE position.
- Engage the parking brake.
- Engage the transmission neutral lock.
- Lower all the work tools to the ground.
- Stop the engine.
- Turn the engine start switch key to the ON position but do not start the engine.
- Move the hydraulic control levers back and forth in order to relieve hydraulic pressure.
- Move the hydraulic control levers to the HOLD position.
- Turn the engine start switch key to the OFF position and remove the key.
- Disconnect the battery.
- Remove the floor mat from the cab.
- Remove the floorplate of the machine.
- Remove the right side rear tire and rim assembly from the machine. Refer to the Disassembly and Assembly manual for correct removal procedures and tools.
 | |
| Illustration 1 | g01302143 |
Remove the right side rear tire. | |
- Drain the hydraulic fluid from the system according to your machine's service manual. Also prepare to contain hydraulic fluid before any hydraulic connections or components are loosened or removed.
 |
Hydraulic oil pressure can remain in the hydraulic system on this machine after the engine and pump have been stopped. Serious injury can result if this pressure is not released before any service is done on the hydraulic systems. In order to prevent possible injury, release the hydraulic system pressure before working on any fitting, hose, or hydraulic component. Lower all attachments to the ground before service is started. If the hydraulic system must be serviced, tested, or adjusted with the attachment in the raised position, the attachments and lift cylinders must be supported properly. 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. |
 |
|
Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |
|
| NOTICE |
|---|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |

Testing and Troubleshooting the Ride Control System
|
To prevent personal injury when checks are made while the machine is in operation, make sure only approved personnel are on the machine. Keep other personnel off the machine and in view of the operator. Make sure checks are done in an open area. |
|
- Engage the parking brake.
- Start the engine. Keep the direction control lever in the NEUTRAL position.
- Check for hydraulic fluid leaks.
If leaks are discovered, stop the machine's engine. Release the pressure in the hydraulic system according to the machine's Service Manual.
Fix any leaks. Check for hydraulic fluid leaks.
|
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. |
|
- Raise the loader bucket off the ground.
- Turn the switch for the ride control system (6) to the ON position. The indicator (53) should appear. See Illustration 43.

- Lower the bucket to the ground. Try to lift the wheels off the ground. If ride control is working properly the machine will not easily lift the front wheels off the ground.
If ride control is not properly working, Check the following items:
- the relay for ride control
- the fuses
- the arc suppressors
- the connections at the switch and at each harness
- the pressure switch
- the relay for ride control
- Lower the stabilizers in order to raise the rear of the machine to 305 mm to 455 mm (12 inch to 18 inch) off the ground.
- Lower the bucket in order to raise the front of the machine to 305 mm to 455 mm (12 inch to 18 inch).
Note: Ride control must be turned off in order to raise the front tires off the ground.
- Engage the ride control system.
Note: For machines with standard transmissions, ride control is turned on by pushing on the top of the switch (6). To turn off ride control, push on the bottom of the switch (6). See Illustration 44.

- Check the machine for any noticeable drift toward the ground. If the machine rapidly drifts, the pressure switch (30) may not be functioning correctly.
- Park the machine according to the machine's Operation and Maintenance Manual.
- Stop the engine.
