1. Lack of Movement or Slow Movement
One of the most frustrating issues is when the machine refuses to move or moves very slowly. This can be caused by several factors, including hydraulic system malfunctions or drive motor failure. Some common causes include:
- Low Hydraulic Fluid: If the hydraulic fluid is low or contaminated, the drive system may not function properly. The fluid is responsible for transmitting power to the wheels through the hydraulic motors. Without sufficient fluid, the system can't generate enough pressure to move the skid steer.
- Faulty Hydraulic Pumps: The Case 1835C's hydraulic system relies on a pump to push fluid to the drive motors. If the pump becomes worn or damaged, it may fail to provide the necessary pressure, leading to a lack of movement or weak drive performance.
- Drive Motor Issues: If the drive motor itself is malfunctioning, either due to wear or internal damage, it may fail to deliver the necessary power to the wheels. This can result in slow or erratic movement.
Another issue that may arise is uneven or jerky movement when operating the machine. This could be due to a variety of reasons, such as:
- Clogged or Dirty Hydraulic Filters: Over time, the hydraulic filters may become clogged with dirt, debris, or contaminants, restricting the flow of hydraulic fluid to the motors. This can cause uneven pressure in the system, leading to jerky movement.
- Faulty Control Valves: The control valves regulate the flow of hydraulic fluid to the drive motors. If a valve becomes stuck or fails to open/close properly, it can cause the fluid to flow unevenly, leading to jerky movement or inconsistent speed.
- Air in the Hydraulic System: Air trapped in the hydraulic lines can cause fluctuations in pressure, leading to erratic movement. This typically occurs if there’s a hydraulic leak or if the system has recently been drained and refilled with fluid.
The joystick controls on the Case 1835C allow the operator to control the direction and speed of the skid steer. If the joystick becomes unresponsive or operates erratically, it can make it difficult to maneuver the machine. This could be caused by:
- Hydraulic Control Valve Issues: The joystick controls are linked to the hydraulic control valves, which direct the fluid to the appropriate drive motors. If these valves become clogged, damaged, or out of adjustment, the joystick may not work properly.
- Linkage Problems: The linkage connecting the joystick to the hydraulic control system may wear out or become misaligned over time, preventing proper operation.
