To switch from standard (std) to joystick (jd) controls on a John Deere 490E excavator, locate the control pattern switch, typically found on the machine's control panel or near the operator's seat. Flip the switch to the desired control pattern. After switching, test the controls to ensure they are functioning as expected. Always consult the operator's manual for specific instructions related to your model.
The serpentine belt pattern for a John Deere 490E excavator typically follows a specific routing to ensure proper tension and function. It generally loops around multiple pulleys, including the alternator, water pump, and other driven components. For precise routing, it's best to refer to the equipment's service manual or a diagram specific to that model, as incorrect routing can lead to belt wear or failure. Always ensure the belt is properly tensioned after installation.
