Subdivisions in the System
Motor graders like the 16M and 16H are complex machines with multiple systems that work in concert to deliver optimal performance. Understanding the subdivision of these systems is critical to both machine repair and long-term maintenance. The main subdivisions in the system include:
- Hydraulic System
- Description: The hydraulic system in a motor grader controls the movement of the blade, as well as other components like the ripper and moldboard. The system uses fluid under pressure to transfer energy and perform work, such as lifting, tilting, and angling the blade.
- Common Issues: Leaks in hydraulic lines, issues with the hydraulic pump, and clogged filters are common problems. In the 16M and 16H, the hydraulic system is robust, but regular checks of fluid levels, lines, and filters are essential.
- Solution: Routine inspection and replacement of hydraulic filters, hoses, and oil are necessary to ensure smooth operation. Additionally, checking the hydraulic pump pressure and replacing worn seals can prevent hydraulic failures.
