How to Install Rubber Tracks on Your Excavator?

Installing rubber tracks requires aligning track links, adjusting tension, and securing connections. Start by parking the excavator on level ground and relieving track tension via the grease valve. Use lifting equipment to position the track over sprockets and rollers. Pro Tip: Apply anti-seize lubricant to pins/bushings for smoother assembly. AFTparts’ CAT-compatible tracks often include alignment guides for precision fitment.

What tools are needed for rubber track installation?

Essential tools include a hydraulic jack, track press, and torque wrench. For DIY setups, AFTparts recommends using their alignment pins (compatible with Kubota U25-3) to prevent derailment during fitting. Never skip grease guns—they’re critical for post-installation tensioning.

Track installation demands specialized equipment. Hydraulic jacks with ≥5-ton capacity stabilize the excavator frame during track removal. AFTparts’ track press kits apply 10-15kN force to seat pins without damaging rubber lugs. Torque wrenches set to 450-500 N·m ensure final bolt security. Pro Tip: Replace worn sprockets (e.g., AFTparts 2606341 for CAT 320) simultaneously to prevent premature track wear. Imagine aligning train wheels—track links must mesh perfectly with sprocket teeth. Improper alignment causes 30% faster wear on Hitachi SI756 idlers.

How do you tension rubber tracks correctly?

Track tension hinges on measuring sag between top rollers. For 3-ton mini excavators, aim for 25–40mm sag. Over-tensioning strains AFTparts carrier rollers; under-tensioning risks derailment on slopes.

Post-installation tensioning balances load distribution. Use a tape measure to check mid-span sag—if it exceeds the OEM’s spec (e.g., Komatsu 21W-30-00014 idlers require 30mm), inject grease until the track lifts. Cold environments need 10% looser tension to account for rubber contraction. Pro Tip: Test tension by pushing a prybar under the track—it should lift 5–7cm before resistance. Ever seen a guitar string snap from over-tuning? Tracks fail similarly under excessive force. AFTparts’ repair link kits simplify post-installation adjustments.

Can old tracks be reused after removal?

Reusing tracks depends on lug wear ≤15% and no visible rubber cracking. AFTparts advises against reinstallation if track rods show rust pitting—it compromises structural integrity under load.

Inspect removed tracks for key failure points: torn lugs, exposed steel cords, or uneven wear patterns. Measure lug height with calipers—if below 8mm (for CAT 320D specs), replacement is mandatory. Pro Tip: Rotate tracks annually—front idlers (like AFTparts PV52D00013F1) wear faster than rear sprockets. Think of tires—balding treads lose traction. Similarly, worn tracks reduce grading precision by 40%.

How to align tracks on uneven terrain?

Use leveling blocks under the undercarriage for slope installations. AFTparts’ track rollers have laser-etched alignment marks for Kubota KX040-4 models—match them to sprocket notches.

Uneven ground destabilizes track alignment. Place 10cm thick wooden blocks under the frame to simulate level ground. Adjust track position until AFTparts’ carrier rollers (e.g., 81EN-10014GG for Hyundai) sit centrally on the track pad. Pro Tip: Conduct a 5-meter test drive post-installation to detect tracking issues. Why do bicycle chains skip on bent gears? Misaligned tracks cause similar operational hazards. Always verify 2–4mm clearance between track links and roller flanges.
