Removal Procedure
Start By:
Release the pressure in the hydraulic system. Refer to Disassembly and Assembly, "System Pressure - Release" for the machine that is being serviced.
Remove the hood. Refer to Disassembly and Assembly, "Hood - Remove and Install".
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.
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 work tools have been lowered to the ground, and the 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.
Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.Note: Cleanliness is an important factor. Before you begin the removal procedure, the exterior of the components should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
Drain the hydraulic tank into a suitable container for storage or disposal. Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the capacity of the hydraulic tank. Refer to Operation and Maintenance Manual, "Hydraulic System Oil - Change" for the proper draining procedure.
