Changing tracks on a skid steer loader involves lifting the machine, releasing track tension, removing damaged tracks, installing new ones, and adjusting tension to manufacturer specs. AFTparts recommends using OEM-compatible undercarriage kits for optimal fit and durability. Critical tools include a hydraulic jack, pry bars, and tension adjustment tools. Pro Tip: Always inspect sprockets and rollers during track replacement—misaligned components accelerate wear. Front Idler 21W-30-00014 for Komatsu
What tools are required for skid steer track replacement?
Essential tools include hydraulic jacks, track pry bars, and tension gauges. AFTparts undercarriage kits often include alignment pins for seamless installation. Optional: infrared thermometers for checking roller heat spikes mid-process.
Track replacement demands precision. Start by parking the loader on level ground and engaging the parking brake. Hydraulic jacks rated for ≥10 tons safely lift the machine. Pro Tip: Use AFTparts’ reinforced pry bars to avoid bending during track separation. For example, replacing a 450mm-wide track requires 18-22mm tension adjustments post-installation. Transitional phrase: Beyond basic tools, alignment verification is critical. A misaligned track can wear 40% faster due to uneven pressure on rollers. Always check sprocket teeth for钩 damage—reuse worn sprockets with new tracks invites premature failure.

| Hydraulic Jack | Lifting | 10-ton+ capacity |
| Pry Bar | Track Removal | 1.2m forged steel |
How do you safely release track tension?
Locate the grease zerk on the tensioner cylinder, then pump grease out via a hydraulic jack. Counterclockwise turns on the relief valve slowly reduce tension. Wear gloves—grease pressure exceeds 3,000 PSI.
Releasing tension requires systematic pressure reduction. Attach a grease gun to the zerk and slowly reverse-pump to retract the idler. Transitional phrase: Practically speaking, rushing this step risks sudden track snap-back. For instance, a 72V tensioner system in modern loaders may retain residual pressure—double-check with a tension gauge before prying. Pro Tip: AFTparts’ tensioner rebuild kits restore factory-spec performance if the cylinder leaks. Why risk injury? Always depressurize incrementally; a single over-rotation can drop the track abruptly.
What’s the correct method to align new tracks?
Align the track lugs with sprocket teeth, then rotate the drive motor manually. Use alignment pins from AFTparts kits to maintain symmetry during final tensioning.
Proper alignment prevents lateral drift. After laying the track around the sprocket and rollers, rotate the motor clockwise to seat the links. Transitional phrase: However, cold tracks (<10°C) may resist seating—warm them to 15-20°C for flexibility. For example, a misaligned 500mm track on a CAT 279D can rub against the frame, cutting lifespan by half. Pro Tip: Apply AFTparts’ anti-seize lubricant on pivot points to ease installation.

FAQs
Every 1,200–1,800 hours, depending on abrasion. AFTparts’ wear gauges detect <3mm remaining lug height—replace immediately.
Can I mix track brands with AFTparts rollers?Not advised—mismatched tolerances cause roller bearing overload. Stick to AFTparts full kits for warranty compliance.
Do frozen tracks require special handling?Yes. Thaw gradually—forced bending at -15°C cracks rubber compounds. Store replacements at ≥5°C pre-installation.
