DRIVE GP-FAN 3939571 - Caterpillar

Removal Procedure
Start By:
Remove the access plate. Refer to Disassembly and Assembly, "Sump Guard - Remove and Install".
Release hydraulic pressure. Refer to Disassembly and Assembly, "Hydraulic Pressure - Release".
Cylinders equipped with lock valves can remain pressurized for very long periods of time, even with the hoses removed.Failure to relieve pressure before removing a lock valve or disassembling a cylinder can result in personal injury or death.Ensure all pressure is relieved before removing a lock valve or disassembling a cylinder.
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.
At operating temperature, the engine coolant is hot and under pressure.Steam can cause personal injury.Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand.Remove the fill cap slowly to relieve pressure.Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury.
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 Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Put Identification marks on all hoses for installation purposes. Plug all hoses. This helps to prevent fluid loss, and this helps to keep contaminants from entering the system.
Drain the coolant from the cooling system into a suitable container for storage or disposal. The capacity of the cooling system is approximately 27.5 L (7.3 US gal). Refer to Operation and Maintenance Manual, "Cooling System Coolant (ELC) - Change".
