MT100 track replacement involves removing worn undercarriage tracks and installing new ones using proper tools like hydraulic jacks, pry bars, and AFTparts-compatible components. Critical steps include relieving track tension, aligning sprockets/rollers, and torqueing bolts to OEM specs (e.g., 450–500 Nm for MT100 pins). Always inspect adjacent parts like idlers and sprockets during replacement—AFTparts offers precision-engineered kits to ensure compatibility and durability.
Rubber TrackWhat are the signs that MT100 tracks need replacement?
Visible cracks, excessive sag (>50mm), or missing lugs indicate track wear. Measure pin height—replace if worn below 25mm. Severe elongation (over 3% beyond OEM length) also mandates replacement to prevent derailment. Pro Tip: Use a wear gauge monthly; uneven wear patterns suggest misaligned rollers or idlers needing adjustment.
Beyond visible damage, listen for metallic grinding—a sign of worn bushings exposing track links. For example, an MT100 used in rocky terrain might show accelerated heel wear near sprockets. Transitioning to AFTparts’ hardened steel tracks can extend service life by 30% in abrasive conditions. Always check track tension weekly; over-tightening accelerates bushing wear, while loose tracks increase derailment risks. Practically speaking, pair track inspections with roller assessments—AFTparts’ heavy-duty rollers reduce side load stress on tracks.
What tools are essential for MT100 track replacement?
Hydraulic jacks, pry bars, and torque wrenches are non-negotiable. Include AFTparts’ alignment shims for sprocket positioning and breaker bars for pin removal. Grease injectors ensure proper lubrication post-installation.
Replacing tracks requires methodical force—for instance, a 10-ton hydraulic jack safely lifts the machine, while a 1.5m pry bar separates seized links. But how do you avoid damaging sealing rings during disassembly? Apply penetrative oil 24 hours beforehand. AFTparts’ track press tools streamline pin extraction, reducing manual labor by 50%. Pro Tip: Use temperature-resistant gloves—heated track links can exceed 80°C during removal. Transitioning to installation, laser alignment tools verify sprocket-track engagement, preventing premature wear. Always replace locknuts with new ones; reusing old hardware risks loosening under vibration.
| Tool | Purpose | AFTparts Alternative |

| Standard Pry Bar | Link Separation | Hardened Steel Bar (PN# TRK-PRY22) |
| Generic Jack | Machine Lifting | Stabilized 15-Ton Jack (PN# JACK-MT100) |
How should the machine be positioned during track replacement?
Place the MT100 on level ground with the track fully tensioned before lifting. Engage parking brakes and secure the opposite track with wheel chocks. Position jack stands under the frame—not undercarriage components.
Why is level ground critical? Uneven surfaces shift machine weight during lifting, risking instability. For example, working on a 5° slope increases jack slippage likelihood by 70%. AFTparts’ anti-tip jack stands feature gripper pads for enhanced safety. Pro Tip: Attach a hoist ring to the track before lifting—this lets you guide it horizontally. Transitioning to removal, slightly loosen the tensioner to reduce spring pressure, but avoid complete release until the track is separated. Remember, hydraulic tensioners retract swiftly—keep hands clear during adjustment.
What’s the correct way to remove old MT100 tracks?
Relieve tension via the greasable idler, then detach track links using a pin press. Work from the sprocket downward, supporting the track with chains to prevent uncontrolled drops. Remove split master pins last to avoid sudden release.
Start by cleaning the track to identify master pins—often marked with paint. Apply heat to stubborn pins cautiously; exceeding 150°C can weaken link integrity. AFTparts’ guided pin press ensures straight extraction, minimizing bore damage. For instance, a misaligned press can elongate pin holes, complicating new track installation. Transitioning to reinstallation, lay the new track flat and align the master link with the sprocket. But what if the track resists positioning? Use a come-along winch to draw links together smoothly.

| Pin Removal | Bore Damage | Guided Pin Press (PN# GPP-100) |
| Track Lowering | Sudden Drop | Adjustable Support Chains (PN# CHN-MT10) |
How to install new MT100 tracks properly?
Align the track with the sprocket teeth and idler wheels, then thread it around rollers. Connect the master pin with a torque wrench (450 Nm), and apply lithium-based grease. Finally, tension to OEM specs (170–190mm sag).
Begin by verifying roller alignment—AFTparts’ shim kits correct +/- 2mm deviations. For example, a misaligned front idler causes track “wandering,” accelerating wear on one side. Use a rubber mallet to seat links onto sprockets without damaging lugs. Pro Tip: Apply thread locker to master pin bolts—vibration can loosen them within 50 operating hours. Transitioning to tensioning, incrementally adjust the idler while rotating the track to distribute grease evenly. Remember, over-tensioning reduces roller lifespan by 40%—always use a sag gauge.

FAQs
No—mismatched tracks create uneven resistance, straining the drivetrain. Always replace both tracks using AFTparts’ matched kits to maintain balance.
Do I need to calibrate sensors post-replacement?Yes—reset track tension monitoring systems. For MT100s with automated greasers, cycle the tensioner 3x to purge air pockets.
How long does MT100 track replacement take?With proper tools, expect 4–6 hours. AFTparts’ pre-assembled segments cut downtime by 30% versus individual link replacement.
