Installation Instructions for the 212-5949 Machine Conversion Ar on the IT14G Integrated Toolcarrier{670B, 7000} Caterpillar

Integrated Toolcarrier:

IT14G (S/N: 1WN1462-UP)

Introduction

This document explains the installation instructions and the machine configuration needed in order to perform the following on the IT14G Integrated Toolcarrier.

• Install the Little & Company TC121 Flail Mower.

• Operate the Little & Company TC121 Flail Mower.

Requirements for Machine Configuration

The following attachments are mandatory when you install the mower.

225-3773 Electrical Converter Gp

This group provides a 24 volt to 12 volt converter with a 12 volt electrical plug. A joystick control operates the mower boom and the position of the head. The joystick control also controls the mower boom and the position of the head. The joystick control requires a 12 volt electrical power supply that is fused.

Note: Machines with the 115-1317 Electrical Converter Gp or the 118-7244 Radio Installation Gp do not need to install the 225-3773 Electrical Converter Gp .

178-0060 Engine Speed Control Conversion Ar

This arrangement provides an electronic speed control for the engine. The electronic speed control for the engine allows the operator to set the engine rpm at any point between LOW idle and HIGH idle.

107-4842 Speed Control Ar

This arrangement provides an additional speed control. This arrangement allows the machine to travel at a low ground speed while the engine operates at HIGH idle. This allows the maximum hydraulic power to be available to the hydraulic attachment.

This arrangement allows the ground speed to be set at any point between zero and the maximum machine ground speed.

Note: This arrangement is not available from the factory on a Miscellaneous Shipping Order. Parts will need to be ordered separately through the parts system.

113-4164 Hydraulic Ar

This arrangement provides quick disconnect fittings and high flow hydraulic hoses. This arrangement is required to drive the Little & Company TC121 Flail Mower.

Restrictions

Tires

These restrictions pertain to the tires when the Little & Company TC121 Flail Mower is installed on the machine.

The machine should not be equipped with 15.5 Bias Ply Tires. The weight of the Little & Company TC121 Flail Mower exceeds the rated load capacity and the speed rate of these tires.

The machine should be equipped with one of the following type of tires when the Little & Company TC121 Flail Mower is installed on the machine.

• 15.5 Radial Tires

• 17.5 Radial Tires

• 17.5 Bias Ply Tires

Brakes

The Little & Company TC121 Flail Mower can only be installed on machines that are equipped with the full hydraulic braking system on both axles. The brake system can not contain a master cylinder. The brake system that contains a master cylinder does not develop enough hydraulic pressure. The additional weight of the Little & Company TC121 Flail Mower dictates a higher machine ROPS rating. The increased ROPS rating is only adaptable to machines that were built with the full hydraulic braking system on both axles. The full hydraulic braking system on both axles became effective with 1WN899.

Machines that were built with a master cylinder booster in the brake system for each axle must not install the Little & Company TC121 Flail Mower.

Note: Although the Little & Company TC121 Flail Mower can be installed on machines with serial numbers 1WN899-UP, the electrical harness for the cab will not support the installation of the engine speed control arrangement. In order to maximize operator control, install the Little & Company TC121 Flail Mower on machines with serial numbers after 1WN1461.

Operator Station

You can only install the Little & Company TC121 Flail Mower on machines that are equipped with an enclosed ROPS cab.

Note: The Little & Company TC121 Flail Mower must not be installed on machines that are equipped with open ROPS canopies.

Safety Feature

Machines that are equipped with a sliding window assembly should contact Little & Company for additional information on the installation of safety screen. This is a highly recommended additional safety precaution.

The safety screen will prevent flying debris from entering the operator station while the Little & Company TC121 Flail Mower is in operation and the right cab window is in the open position.

Machines that are equipped with cab doors with fixed glass do not require the additional protection of the safety screen.

Note: The Little & Company TC121 Flail Mower should never be operated with the right cab door in the open position. Always refer to the Little & Company Operation and Maintenance Manual. Refer to the "Safeguards" section for the safe working practices.

Procedure to Obtain a Higher-Rated ROPS/FOPS Plate

Application for a Higher-Rated ROPS/FOPS Plate for the IT14G Integrated Toolcarrier

The applicable serial number range is 1WN899-1939.

Customers that install the Little & Company TC121 Flail Mower must obtain a higher-rated ROPS plate from Caterpillar. The 212-6496 ROPS/FOPS Plate must be installed on the machine. The 212-6496 ROPS/FOPS Plate replaces the 120-5714 ROPS/FOPS Plate that was originally installed on the machine.

The 212-6496 ROPS/FOPS Plate increases the weight for the ROPS structure from 9000 kg (19840.0 lb) to 11000 kg (24255.0 lb).

An application for the new higher-rated ROPS/FOPS plate can only be accepted when the application is made via a written request. The written request will only be accepted when the request is completed by an authorized Caterpillar dealer. The written request must be submitted to Small Wheel Loaders, BCP Marketing or the Product Support Group at the address below.

BCP Marketing & Product Support Group
954 NC 42 East
Clayton, North Carolina 27520

Before a new higher-rated ROPS/FOPS plate is issued, each request will be evaluated on an individual basis. If the machine meets the criteria for the Little & Company TC121 Flail Mower the machine must also be approved by Caterpillar. The Caterpillar dealer must return the original ROPS/FOPS plate to the above address.

Note: Any ROPS/FOPS plate that is returned will be documented by Caterpillar. Then, the ROPS/FOPS plate will be destroyed. Machines that fail to meet the criteria for the Little & Company TC121 Flail Mower will not receive the new ROPS/FOPS plate.

Installation of the Electrical Circuit for the Mower Boom Control

This section covers the installation of the electrical circuit for the mower boom control. An electric joystick handle controls the functions of the mower boom. The joystick handle will be mounted above the pilot control valve inside the operator station.

Installation of the electric joystick handle will require the removal of the handle to the pilot valve. If the machine is equipped with the remote forward/neutral/reverse lever, one 101-9161 Wire will need to be installed at the four-pin connector of the harness for the transmission shift lever.

The electric joystick handle requires a 12 vdc power supply. The 12 vdc power supply is supplied by the 12 vdc accessory outlet. In order to obtain electric current on an electric circuit from the 12 vdc accessory outlet that has a switch and a fuse, the machine must contain one of these three groups.

• 225-3773 Electrical Converter Gp

• 115-1317 Electrical Converter Gp

• 118-7244 Radio Installation Gp

Electric power to the electric joystick handle is controlled via a lockout switch that is positioned in the switch group console that is behind the electric joystick handle. The lockout switch electrically controls the electric joystick handle in order to prevent inadvertent motion of the mower boom during transportation.

Note: Before you start the machine, turn off the lockout switch for the electric joystick handle. This will protect the electronic circuits inside the electric joystick handle. The switch will prevent the inadvertent movement of the mower boom during engine start-up. Refer to the Little & Company Operators Manual for safety and operation instructions.

The cover for the console group will also need to be modified in order to accept a grommet. This grommet will allow the "2030603" Main Frame Harness to pass through the console. Also, the grommet will allow the "2030603" Main Frame Harness to connect to the "2030604" Joystick Harness.

Adjust the Line Relief Valve for the Auxiliary Circuit on the Bank Valve

To achieve the optimal power at the hydraulic motor that drives the flail/rotary head, you must adjust the setting on the head end of the line relief valve for the auxiliary circuit.

Refer to System Operations, Testing and Adjusting, SENR6774, "914G Wheel Loader& IT14G Integrated Toolcarrier Hydraulic System", "Auxiliary Cylinder Relief Valve" for the procedure to adjust the setting of the relief valve.

The setting for the auxiliary circuit relief valve from the factory is 20700 ± 350 kPa (3000.0 ± 50.0 psi). To achieve the optimal power at the hydraulic motor that drives the flail/rotary head, you must increase the relief valve setting to 24150 ± 350 kPa (3500.0 ± 50.0 psi).

Note: The main relief valve setting will need to be increased above the standard setting in order to set the auxiliary circuit relief valve. Once you have set the auxiliary circuit relief valve, return the main relief valve setting back to the factory setting. Set the main relief valve to 24150 ± 350 kPa (3500.0 ± 50.0 psi).

Flow Control Settings for the Pivot Cylinder and the Boom Cylinders for the Mower

Before you operate the mower, the flow of hydraulic oil needs to be correctly set for the pivot cylinder and the boom cylinders for the mower. The flow is controlled via a needle valve at the rod end of each cylinder except for the pivot cylinder. The pivot cylinder use a needle valve on both the rod end and the head end of the cylinder.

Note: It is important to correctly set the flow control at each cylinder in order to maintain a safe travel speed for the cylinder. The needle valves can be adjusted to the preference of the operator. Open the needle valve in order to increase the flow of oil. Close the needle valve in order to reduce the flow of oil. The settings in the following steps are recommended in order to obtain the following.
