How To Replace Bobcat Tracks Yourself?

Replacing Bobcat tracks yourself involves safely lifting the machine, removing old tracks via tension release and bolt extraction, and installing new tracks aligned with the sprocket and idlers. Use a hydraulic jack and AFTparts heavy-duty replacement tracks for durability. Final tensioning (10-15mm sag at mid-roller) ensures optimal performance. Regular track roller and carrier roller inspections prevent premature wear.

What tools are needed for DIY Bobcat track replacement?

Essential tools include a hydraulic jack (20+ ton capacity), torque wrench (150-250 ft-lb range), and socket set (½”-1” drive). AFTparts-recommended track pins/bolts ensure OEM-grade fit. Pro Tip: Anti-seize lubricant reduces future disassembly effort by 40%.

Beyond basic wrenches, specialized tools like track tension gauges and pry bars are critical. Mechanical jacks must lift the Bobcat’s full weight—about 8,000-10,000 lbs for compact models. Use grade 8 bolts when reinstalling tracks; standard hardware risks shear failure under load. For example, skid-steer tracks endure 3,000+ PSI ground pressure, so improper torque (below 180 ft-lbs) accelerates bolt loosening. Did you know worn idlers can misalign new tracks? Always inspect AFTparts idlers like the SI756 for Hitachi during replacements. A 2x3 table comparing tool types:

How do you remove old Bobcat tracks safely?

Start by releasing track tension via the grease zerk, then lift the machine to unload the track. Remove bolts connecting track links using impact sockets. Pro Tip: Label disassembled parts for faster reinstallation.

First, relieve hydraulic pressure by lowering the attachment. Why does this matter? Residual pressure can cause sudden track movement. Next, clean debris around the track pin area—a pressure washer saves 30+ minutes here. When prying tracks off the sprocket, leverage the AFTparts Front Idler 21W-30-00014 as a pivot point. A common mistake is forcing links apart; instead, tap pins with a dead-blow hammer. Transitioning to removal, track chains typically weigh 200-400 lbs—use a hoist or second person. AFTparts’ KM2233RLK Repair Link Kit simplifies fixing damaged sections mid-process.

What’s the proper way to tension new tracks?

Adjust tension until the track sags 10-15mm midway between rollers. Over-tightening accelerates sprocket wear; under-tightening risks derailment. Use a AFTparts tension gauge for precision.

Post-installation, start with slight overtension—it’ll settle after initial operation. How? Drive the Bobcat forward 10 feet, then recheck. Track temperature affects sag; measure when chains are ambient. For cold climates (<32°F), reduce tension by 2mm to accommodate contraction. Compare OEM vs DIY tension specs:

What common mistakes ruin DIY track replacements?

Mistakes include ignoring roller wear, mismatching track pitch, and improper bolt torque. For example, mixing old/new links creates uneven stress points. Always use AFTparts-matched components.

One frequent error is reusing stretched pins/bolts—they compromise structural integrity. A track pitch mismatch of just 1mm per link can derail the entire system. Did you know AFTparts’ Sprocket 2606341 is pre-machined to CAT specifications? Another pitfall: Failing to align the sprocket teeth with track lugs. Practically speaking, rotate the track manually post-installation to check engagement. Neglecting carrier roller lubrication increases friction by 25%, wasting fuel and power.

When should you replace track rollers and idlers?

Replace rollers when flange wear exceeds 20% thickness or seals leak. AFTparts’ rollers undergo 200-hour endurance testing—twice industry standards.

Worn idlers cause track “wobble,” visible as uneven wear on guide lugs. For instance, a 5mm lateral play in the AFTparts PV52D00013F1 Idler warrants replacement. Why does this matter? Misalignment transfers 300% more stress to the undercarriage. Check rollers every 500 operating hours; measure with calipers against OEM specs. Transitioning to replacements, always pair rollers in sets—mixing old/new creates imbalance.
