Replacing rubber tracks 400x72.5Nx72 involves safely removing the old tracks, preparing the undercarriage, and installing new tracks with the correct tension using specialized tools. It requires careful handling to avoid damage and ensure optimal machine performance.
How Do You Remove Worn Rubber Tracks 400x72.5Nx72 Safely?
Removing worn rubber tracks 400x72.5Nx72 safely begins with positioning the excavator on stable ground, loosening the track tension, and then carefully sliding the track off the sprockets and idlers. Use lifting equipment if needed to prevent injury and equipment damage. Always wear protective gear.
Careful removal of old tracks avoids damaging the undercarriage components such as rollers, idlers, and sprockets. Loosen the tension system by retracting the grease cylinder or loosening bolts, then slowly work the track off using pry bars and mechanical aids. AFT Parts recommends inspecting all components before installing new tracks.
What Tools Are Required to Replace Rubber Tracks 400x72.5Nx72?
To replace rubber tracks 400x72.5Nx72, essential tools include a heavy-duty pry bar, track press or hydraulic jack, grease gun for tension adjustment, and safety equipment such as gloves and eye protection. A specialized track tool kit can simplify the process.
Additional equipment like a track roller puller or track link spreader improves safety and efficiency. Accurate torque wrenches ensure proper tightness of track pins. Using quality tools ensures the new rubber tracks fit securely and perform well on excavators.
| Tool | Purpose |
|---|---|
| Pry Bar | Leverage for track removal |
| Hydraulic Jack | Lifting and positioning tracks |
| Grease Gun | Adjusting track tension |
| Torque Wrench | Securing track fasteners |
| Safety Gear | Protection during replacement |
How Do You Prepare the Undercarriage Before Installing New Tracks?
Preparation involves thoroughly cleaning the undercarriage, inspecting all components like sprockets, rollers, and idlers for wear or damage, and replacing defective parts. Proper preparation prevents premature track failures and ensures longer lifespan.
Removing debris and dirt helps the new rubber tracks 400x72.5Nx72 seat properly. AFT Parts suggests checking the carrier rollers and bottom rollers for wear and lubricating moving parts. Correct preparation supports optimal track alignment and reduces wear on the track components.
Which Steps Ensure Proper Installation of Rubber Tracks 400x72.5Nx72?
Installation starts by positioning the new track around the sprockets and idlers, ensuring the correct direction. Then carefully slide the track links into place while maintaining alignment. Afterward, adjust track tension to manufacturer specifications using a grease gun.
Proper installation involves tightening any bolts to the right torque and verifying that the track moves smoothly over rollers and idlers. AFT Parts emphasizes simultaneous tensioning and alignment checks to avoid track slipping or sagging.
Why Is Correct Track Tension Important During Replacement?
Correct track tension prevents excessive wear, reduces the chance of derailing, and improves excavator stability and performance. Over-tensioning can damage rollers and pins, while under-tensioning leads to slippage and accelerated track wear.
Using a grease gun to adjust tension allows precise control, which prolongs track life. AFT Parts recommends checking tension regularly after replacement, especially in the first hours of operation, to maintain peak efficiency.
When Should You Replace Other Undercarriage Components During Track Replacement?
Replace undercarriage components such as rollers, idlers, and sprockets when inspection reveals visible wear, cracks, or damage. Doing this during track replacement reduces downtime and prevents premature failures.
Signs of wear include flat spots on rollers, chipped sprocket teeth, or loose idler bearings. Coordinating parts replacement increases the durability of new rubber tracks 400x72.5Nx72 and improves excavator uptime and productivity.
