ReferenceSpecial Instruction, REHS6088, "Field Procedure to Update the Cooling Arrangement on the 797F Off-Highway Truck"
A new special instruction is available. This special instruction provides the information that is needed to install the following new parts: a new fan support, new fan covers, new fan motor cover, new tubes, new clipping locations for water lines, new hydraulic hoses and clipping locations for the fan motor hydraulic lines
The new parts will prevent the fan from contacting the radiator that results in leaks. The information is adaptable to machines LAJ1-265. The new parts became effective in production with machines LAJ266-UP.
The procedure should be done at the planned component rebuild for the engine. The procedure can also be done when repairs are being done that require the radiator to be removed from the machine.
For a complete list of material, and the correct procedure that is needed to update the cooling arrangement to the current configuration, refer to the above listed special instruction. The special instruction can be found on the Caterpillar service information system (SIS), and through the normal literature distribution system at your local Cat dealer.
