Safety

Show/hide table

Pressurized System: Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pressure. Read and understand the Operation and Maintenance manual before performing cooling system maintenance.

Show/hide table

Personal injury can result from contact with refrigerant. This system is under pressure at all times, even if the engine is not running. Heat should never be applied to a charged system. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury. Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant. Always use caution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, evacuate the system recovering the refrigerant before removing the fitting. Personal injury or death can result from inhaling refrigerant through a lit cigarette. Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present. Before any checks of the air conditioning and heating system are made, move the machine to a smooth horizontal surface. Lower all implements to the ground. Make sure the transmission is in NEUTRAL or PARK and that the parking brake is engaged. Keep all other personnel away from the machine or where they can be seen.

Required Parts

Prepare the Machine for Service

1. Park the machine on a flat, level work surface.

2. Lower all implements to the ground.

3. Place the transmission in either neutral or park.

4. Engage the parking brake.

Electrical Installation

Note: All models follow 2013 299D-XHP instructions except 2012 299D-XHP which special instructions follow.

Refer to Operation and Maintenance, "Loader Lift Arm Brace Operation"

If installing 435-9237 Fan Reversing Kit on a D2 series machine, the wiring harness built into machine and electrical connector will need to be plugged into solenoids.

Raise the cab. Ensure that the cab support lever is fully ENGAGED before proceeding. Refer to Operation and Maintenance, "Cab - Tilt"

To begin the electrical harness installation, the cab of the machine must be lifted per the Operation and Maintenance, "Cab - Tilt"

Once the cab is safely tilted into position and secured, the cab electric harness can be installed.

(T) Existing cover (U) Existing fastener

1. Installation onto a 2012 machine requires a 25.4 mm (1 inch) diameter hole to be drilled into the cab to allow the wiring harness to be installed. Placement of the hole is to be on the back shelf of the cab. To access the area in which to drill the hole, existing cover (T) must be removed. Remove existing fastener (U) and remove the cover.
   Show/hide table

   Illustration 12	g03690697

2. With the covering removed a 12-pin connector should be visible, and the drilling area directly underneath should be visible.

1. Gather harness (7), connect receptacle connection of harness (7) to plug connection of wire harness (8) in engine bay of machine. Return to area where wire harness (8) was fed through the firewall and pull slack. On harness (7) is diode (46), which must be removed and the connector must be capped with seal cap (47).

2. Zip tie harness (7) in position with demand fan solenoid harness.

3. Connect two-pin connector of harness (7) into reversing 449-1570 Solenoid receptor.

4. Connect demand fan solenoid two-pin connector on 356-6084 Harness (previously on machine with demand fan installed) into receptor on 277-8862 Solenoid. Zip tie loose wiring to secure mount. Ensure proper electrical connections.

5. Once components are installed, unhinge radiator and bolt back into place. Bolt cab in place and ensure proper fit.

   Note: On 2012 machines, when bolting radiator down insert 5R-5927 Washer on top of radiator bracket. Therefore two 5R-5927 Washers should be on top of the bracket and one should be underneath the bracket, all fastened by a bolt and nut.

Software Install and Configuration

Software must be flashed onto machine via Winflash and then can be controlled through Caterpillar ET. The following outlines the procedure for installing the appropriate software onto the machine.

Note: Once software has been flashed onto machine a fan calibration sequence must be completed

Reverse Fan - Software Flashing

Connect the Communication Adaptor (CA-2, CA-3) between laptop and service tool connector. Service tool connector is on the right-hand side when sitting in the cab.

Open Winflash Application (2014A or Higher). When ECU displays, select Machine ECU.

Note: Flash file is now a f12 format (as of April 2014) and requires Winflash 2014A or newer.

Flash the software that supports the reversing fan components.

• Tier4F and Tier4I (2013): 503-7999 or higher

• Tier4I (2012): 468-7994 or higher

Engine Cooling Fan group configuration settings

(1). Engine Cooling Fan Installation: This must be set to ON to enable reversing fan install.

(2). Reversing Fan Installation: Set this to INSTALLED to enable the reversing solenoid, to monitor the fan switch in the cab and utilize the timers.

(3). Operation Interval: This is how often the reversing fan will automatically function. (6 minutes to 240 minutes)

(4). Reverse Operation Time: This is how long the reversing fan will operate in reverse mode when switch pressed or automatic interval expires. (5 seconds to 12 seconds)

Reversing Fan Configuration - Feature

With components installed and feature installed via ET. Confirm no diagnostics active (switch - solenoid).

Feature will function based on the switch position. Off, Auto, or Operator Activated.

reversing Fan will not activate by switch until 30 seconds after machine is running.
