Removal Procedure
Start By:
- Remove the engine enclosure (hood). Refer to Disassembly and Assembly, "Engine Enclosure (Hood) - Remove and Install".
- Remove the exhaust (muffler). Refer to Disassembly and Assembly, "Exhaust (Muffler) - Remove and Install".
- Remove the air cleaner. Refer to Disassembly and Assembly, "Air Cleaner - Remove and Install".
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact the skin. Be sure that the engine and components are cool enough to touch with your bare hand prior to performing any service work. |
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. |
Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand. Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns. Cooling System Conditioner contains alkali. Avoid contact with skin and eyes. |
