How to Remove the Track on a 1996 CAT D5C Bulldozer

[MikePhua]

Removing the track on a bulldozer, like the 1996 CAT D5C, is an essential skill for maintenance and repair work. Whether you're replacing the track, inspecting the undercarriage, or performing routine maintenance, the process requires careful attention to detail and safety. In this guide, we will walk through the necessary steps to safely and effectively remove the track from a CAT D5C, using basic tools and following the manufacturer’s guidelines.
The CAT D5C is a mid-sized crawler tractor known for its power and versatility. Its undercarriage, including the tracks, is designed to handle rugged conditions, but over time, components may wear down and need replacing. Understanding how to remove the track correctly is crucial to maintaining the machine’s performance.
Understanding the CAT D5C Undercarriage
Before diving into the track removal process, it's important to understand the key components of the undercarriage system on a CAT D5C:

• Track Link: The individual pieces that make up the track assembly.
  
• Track Rollers: Support the track and allow it to move smoothly.
  
• Idler: The front part of the track assembly that maintains tension and guides the track.
  
• Drive Sprocket: A toothed wheel that engages with the track to drive the vehicle.
  
• Track Tensioner: A hydraulic system that adjusts the track tension for optimal performance.
  

The D5C utilizes a sealed and lubricated track (SALT), which is common in many CAT machines. Regular maintenance of these components is essential for ensuring that the machine runs smoothly and efficiently.
Step-by-Step Guide to Removing the Track
Removing the track from a 1996 CAT D5C involves several steps that require basic tools and a careful approach. Here’s a detailed breakdown of the process:
1. Prepare the Work Area
Before starting any disassembly, ensure the work area is clear and safe. Position the bulldozer on a flat, level surface, and engage the parking brake to prevent the machine from moving during the procedure. Having proper lighting and ample space around the machine will make the process easier.

• Safety Tip: Always wear proper protective gear, including gloves, steel-toed boots, and safety goggles, to protect against debris and sharp parts.
  

2. Lift the Bulldozer
Using a hydraulic jack or a similar lifting device, carefully raise the bulldozer off the ground. It’s crucial to lift the machine just high enough to allow the track to be removed without overloading the lift equipment.

• Support the Machine: Place jack stands or another form of secure support under the machine to prevent it from shifting or falling once it’s raised.
  

3. Relieve Track Tension
The next step is to relieve the tension on the track to make it easier to remove. This involves adjusting the track tensioner, a hydraulic component located on the undercarriage. The tensioner controls how tightly the track is applied to the rollers and sprockets.

• Track Tensioner Adjustment:
  • Locate the track tensioner on the undercarriage.
    
  • Use a wrench or hydraulic tool to release the tension.
    
  • Once the tension is released, check for any unusual movement or slack on the track.
    

This step is critical because if the track is under too much tension, it may be difficult to remove. Conversely, if it’s too loose, the track may come off unexpectedly during the removal process.
4. Remove the Track Adjuster Nut
On the D5C, the track adjuster is typically located on the idler assembly. To remove the track, you’ll need to remove the track adjuster nut. This nut holds the adjuster in place and allows the track to be disengaged.

• Tools Needed: Use a heavy-duty wrench or socket set to remove the adjuster nut.
  
• Removing the Nut: Turn the nut counterclockwise to loosen it. Once removed, set the nut aside, as you’ll need it later for reassembly.
  

5. Disconnect the Track from the Drive Sprocket
Once the adjuster nut is removed, the next step is to disconnect the track from the drive sprocket. The drive sprocket is the wheel that engages with the track, and it must be removed to free the track.

• Tools Needed: You may need a puller tool or a large hammer to help remove the sprocket.
  
• Procedure:
  • Locate the bolts or fasteners that secure the sprocket to the axle.
    
  • Use a wrench or impact tool to remove the bolts or fasteners.
    
  • Once removed, carefully slide the sprocket off the axle.
    

6. Remove the Track from the Undercarriage
With the drive sprocket disconnected, the next step is to remove the track from the rest of the undercarriage components. This includes the rollers, idler, and track links.

• Careful Handling: Use a combination of lifting tools and manual labor to carefully slide the track off the rollers and idler. It may require some force to break the track’s grip on these components, but be sure to apply force gradually to avoid damaging the parts.
  
• Track Link Removal: Depending on the configuration of the track, you may need to remove the track links individually. This involves unscrewing the bolts or pins that connect the links. Keep track of these small components as they will need to be reassembled later.
  

7. Remove the Track
Once the track is free from the sprocket, rollers, and other components, you can slide the track off the undercarriage. This may require some maneuvering, especially if the track is large or heavy.

• Lift the Track: Carefully lift the track off the machine using a crane or other lifting device. Track removal is a two-person job, so ensure that you have help to avoid injury.
  

8. Inspect and Clean the Track Components
Once the track is removed, inspect the condition of the track, rollers, and other undercarriage components. Check for signs of wear, cracks, or damage that may require repair or replacement.

• Track Inspection:
  • Inspect the links for cracks or excessive wear.
    
  • Check the rollers for damage or signs of rust.
    
  • Clean the components to remove dirt, grease, and debris.
    

Regular inspection and cleaning can extend the life of your tracks and help identify problems early on.
Reassembling the Track
Reassembling the track on a CAT D5C is the reverse process of removal. When reassembling, make sure to carefully inspect each component before reinstalling it. Reapply the correct track tension and reattach the drive sprocket, adjuster nut, and other components. Proper tension is crucial to prevent excessive wear on the track and to ensure smooth operation.

• Track Tension: Once the track is reinstalled, use the track tensioner to adjust the track tension to the manufacturer’s specifications.
  
• Re-tightening Bolts: Ensure all bolts and fasteners are securely tightened to prevent any parts from loosening during operation.
  

Conclusion
Removing the track on a 1996 CAT D5C requires careful planning, the right tools, and attention to detail. By following the steps outlined in this guide, you can safely remove and replace the track, inspect key components, and maintain your bulldozer for optimal performance. Regular maintenance of the undercarriage and track system is essential for ensuring that your CAT D5C continues to perform well in even the most demanding conditions.
