Excavator track rollers are critical for smooth operation and undercarriage longevity. To inspect them for wear and damage, you should perform a detailed visual check for cracks, dents, and seal leaks, test roller rotation, listen for unusual noises, assess track tension, clean debris, and document your findings. Canadian buyers can shop online for replacement rollers with deals, best prices, and free shipping.
How Do You Prepare for a Safe Track Roller Inspection?
Shut off the excavator engine and remove the key to prevent accidental startups. Engage the parking brake on level ground and chock the tracks to prevent movement. Wear protective gear such as gloves and safety glasses before beginning the inspection to ensure safety during the process.
What Should You Look for During a Visual Track Roller Inspection?
Inspect the roller surfaces for dents, cracks, flat spots, or excessive wear. Check seals for cracks, tears, or grease leaks, which indicate potential bearing contamination. Ensure the rollers are correctly aligned with the undercarriage frame and check bolts for any looseness or damage.
How Can You Test the Functionality of Excavator Track Rollers?
Manually rotate each roller; it should spin smoothly without grinding or resistance. Start the machine and move it slowly, listening for abnormal noises like grinding or clunking, which may suggest bearing failure or loose mounts.
Why Is Proper Track Tension Vital When Inspecting Track Rollers?
Correct track tension prevents undue stress on rollers and bearings. Measure track sag: rubber tracks typically require 20-25mm sag, steel tracks 15-20mm. Adjust tension per manufacturer instructions to avoid premature wear or track derailment, preserving roller life.
How Should You Clean and Lubricate Track Rollers?
Remove dirt, gravel, and debris from roller surfaces and seals using brushes or compressed air. Locate grease fittings and apply NLGI 2 lithium-based grease without over-lubricating to avoid attracting dust and dirt, which can degrade seals and bearings.
