Common Problems with Terex TC 35 Drive Motors
- Loss of Power or Slow Movement
- Symptom: One of the most common problems reported by operators of the Terex TC 35 is a loss of power or slow movement, even when the throttle and controls are set properly. The machine may struggle to move, and tracks may feel sluggish when trying to turn or move forward.
- Cause: This issue can be caused by several factors. The most common causes include:
- Low Hydraulic Fluid Pressure: If the hydraulic pump is not generating enough pressure, the drive motors won’t get the required power to move the tracks effectively.
- Hydraulic Fluid Contamination: Contaminated hydraulic fluid can clog filters or damage internal components of the drive motor, resulting in slow operation or complete failure.
- Worn or Faulty Drive Motors: Over time, wear and tear on the internal components of the motor, such as seals or bearings, can reduce its efficiency and cause sluggish movement.
- Low Hydraulic Fluid Pressure: If the hydraulic pump is not generating enough pressure, the drive motors won’t get the required power to move the tracks effectively.
- Symptom: One of the most common problems reported by operators of the Terex TC 35 is a loss of power or slow movement, even when the throttle and controls are set properly. The machine may struggle to move, and tracks may feel sluggish when trying to turn or move forward.
- Unusual Noises or Vibrations
- Symptom: Unusual grinding, whining, or other abnormal noises from the drive motor area can indicate serious issues. These noises may be accompanied by excessive vibrations while the machine is in operation.
- Cause: The causes of unusual noises in the drive motor system may include:
- Worn Bearings or Gears: Over time, bearings inside the drive motor can wear out, leading to grinding noises and vibrations. This can also be a sign of a misalignment in the motor components.
- Internal Damage from Contamination: If foreign particles enter the hydraulic system, they can cause internal damage to the motor components, leading to malfunction and noise.
- Loose or Faulty Hydraulic Hoses: Vibrations or noise might also arise from improperly secured or cracked hydraulic hoses supplying the drive motor.
- Worn Bearings or Gears: Over time, bearings inside the drive motor can wear out, leading to grinding noises and vibrations. This can also be a sign of a misalignment in the motor components.
- Symptom: Unusual grinding, whining, or other abnormal noises from the drive motor area can indicate serious issues. These noises may be accompanied by excessive vibrations while the machine is in operation.
- Uneven Track Movement
- Symptom: If the tracks are not moving in sync, or if the machine drifts to one side when trying to move in a straight line, this can indicate a problem with the drive motor or the hydraulic system.
- Cause: Uneven track movement can often be traced to:
- Drive Motor Imbalance: If one motor is malfunctioning or less effective than the other, it may cause uneven movement in the tracks.
- Hydraulic Pressure Imbalance: Uneven hydraulic pressure in the system can result from blockages or issues in the pump, hoses, or valves.
- Drive Motor Seal Leaks: Leaks in the seals of the drive motor can cause a drop in hydraulic pressure, leading to uneven power distribution between the motors.
- Drive Motor Imbalance: If one motor is malfunctioning or less effective than the other, it may cause uneven movement in the tracks.
- Symptom: If the tracks are not moving in sync, or if the machine drifts to one side when trying to move in a straight line, this can indicate a problem with the drive motor or the hydraulic system.
- Leaks from the Drive Motor Area
- Symptom: Hydraulic fluid leaks around the drive motor area, particularly near seals and hoses, are another common issue that can cause poor machine performance.
- Cause: Leaks can occur for several reasons:
- Worn Seals: As seals age, they can become brittle and lose their ability to hold hydraulic fluid. This can lead to fluid loss and pressure drop in the hydraulic system.
- Damaged Hoses: Over time, hydraulic hoses may crack or degrade, leading to leaks at connection points.
- Improper Assembly or Installation: Incorrect installation of seals or hoses can cause leaks, which may worsen over time if not addressed.
- Worn Seals: As seals age, they can become brittle and lose their ability to hold hydraulic fluid. This can lead to fluid loss and pressure drop in the hydraulic system.
