Changing hydraulic and steer motor brushes can be a challenging task, but there are certain ways to make it easier. To remove the steer motor brushes, you may need to disconnect the wires and use a special tool to access and remove them. As for the hydraulic brushes, try to use a flexible extension to reach the last one next to the counterweight. If the pump hoses are too tight, you can try to loosen them just enough to access the brush, but be sure to have a bucket or container to catch the oil leakage. Remember to wear protective gear and follow the manufacturer's instructions for your safety. Good luck!
