Why Is the John Deere CT322 Track Loader Sticking Out of Alignment

[MikePhua]

The CT322 and Its Role in Compact Construction
The John Deere CT322 compact track loader was introduced in the mid-2000s as part of Deere’s expansion into the CTL market. With a 66-horsepower diesel engine, a rated operating capacity of 2,200 lbs, and a vertical lift path, the CT322 was designed for grading, loading, and material handling in confined spaces. Its rubber track undercarriage provided low ground pressure and excellent traction on soft or uneven terrain.
John Deere, founded in 1837, has long been a leader in agricultural and construction equipment. The CT322 helped solidify Deere’s presence in the compact equipment segment, with thousands of units sold across North America. Its popularity stemmed from its balance of power, maneuverability, and attachment versatility.
Identifying Track Misalignment Symptoms
Track misalignment on a CT322 typically presents as one track protruding farther than the other, uneven wear on the tread, or difficulty maintaining straight travel. Operators may notice:

• One track riding outside the frame more than the other
  
• Uneven tension between left and right tracks
  
• Excessive wear on sprockets or rollers
  
• Steering drift or pulling to one side
  

These symptoms can result from mechanical wear, hydraulic imbalance, or frame distortion. Left unaddressed, misalignment can lead to premature undercarriage failure and reduced operator control.
Undercarriage Design and Alignment Factors
The CT322 uses a rigid frame with a suspended undercarriage system. Each track is supported by:

• Drive sprocket
  
• Front and rear idlers
  
• Multiple bogie rollers
  
• Tensioning mechanism (grease-filled cylinder)
  

Track alignment depends on the geometry of these components and the integrity of the frame. If any part shifts, bends, or wears unevenly, the track may appear offset.
Key causes of misalignment include:

• Bent or worn track frame
  
• Uneven tensioning due to grease loss or cylinder failure
  
• Damaged idler mounts or roller brackets
  
• Sprocket wear causing lateral movement
  

A contractor in Tennessee reported that his CT322 began pulling to the right after a winter job on frozen gravel. Inspection revealed a cracked rear idler bracket, causing the right track to shift outward. After welding and realignment, the machine tracked straight again.
Hydraulic Influence on Track Behavior
While the CT322’s tracks are mechanically guided, hydraulic drive motors control their movement. If one motor delivers less torque or responds slower, the machine may veer or cause uneven wear.
Hydraulic-related issues include:

• Internal leakage in one drive motor
  
• Contaminated fluid affecting valve response
  
• Uneven case drain flow
  
• Faulty joystick calibration
  

To diagnose hydraulic imbalance:

• Compare drive motor temperatures after operation
  
• Check case drain flow rates
  
• Inspect hydraulic filters and fluid condition
  
• Test joystick response and recalibrate if needed
  

If the hydraulic system is healthy but alignment persists, mechanical inspection is the next step.
Track Tension and Adjustment Procedure
Improper tension is a leading cause of misalignment. The CT322 uses a grease-filled tensioning cylinder to push the front idler forward, maintaining track sag.
To adjust tension:

• Lift the machine to unload the track
  
• Locate the grease fitting near the front idler
  
• Add grease until the track sag is approximately 1 inch when lifted
  
• Compare both sides for symmetry
  

If one side loses grease faster, the cylinder seal may be leaking. Replace seals or the entire cylinder to restore balance.
Frame and Structural Inspection
In rare cases, the main frame may be bent or twisted due to impact or overloading. Signs include:

• Uneven track spacing at rest
  
• Misaligned lift arms or bucket
  
• Cracks near welds or pivot points
  

Use a tape measure to compare track spacing at multiple points. If discrepancies exceed 0.5 inches, frame distortion is likely. Consult a certified technician for laser alignment or jig-based straightening.
Preventive Measures and Operator Habits
To minimize track misalignment:

• Inspect undercarriage weekly for wear or damage
  
• Maintain proper track tension on both sides
  
• Avoid sharp turns on hard surfaces
  
• Clean debris from rollers and sprockets
  
• Service hydraulic system every 500 hours
  

Operators should be trained to recognize early signs of misalignment and report changes in steering or track behavior. A proactive approach prevents costly repairs and improves machine longevity.
Conclusion
Track misalignment on the John Deere CT322 can stem from mechanical wear, hydraulic imbalance, or structural distortion. By understanding the undercarriage layout, monitoring tension, and inspecting components regularly, operators can maintain alignment and ensure safe, efficient operation. The CT322 remains a capable and dependable machine—provided its tracks stay true to the path.
