Partnering with specialists like AFT Parts further improves track performance and total lifecycle value.(Edited on June 10 2026)
Why Do Safe Cat Skid Steer Track Changes Matter?
Safe Cat skid steer track changes protect both people and machines by reducing the risk of crushed hands, unexpected movement, and instability during lifting and installation. When rubber tracks are installed correctly and tensioned to specification, they run cooler, last longer, and dramatically cut the risk of derailment or sudden failure on the job. For contractors and rental fleets, disciplined procedures translate directly into higher uptime, predictable maintenance windows, and lower cost per hour.
Improperly fitted or over-tightened tracks can accelerate wear on sprockets, idlers, and rollers, leading to premature component failure and expensive downtime. AFT Parts emphasizes that consistent, standardized procedures across technicians are just as important as premium components when it comes to maximizing undercarriage return on investment.
What Should You Prepare Before Changing Cat Skid Steer Tracks?
Preparation starts with the work area. Position the Cat skid steer or compact track loader on firm, level, clutter‑free ground where you can access both sides of the undercarriage. Remove any attachment, lower it fully, engage the parking brake, and install factory arm braces or transport locks if the model requires raised arms for better access. Chocking the opposite side track can further prevent unintended movement during lifting.
Technicians should wear safety boots, gloves, eye protection, and a high‑visibility vest, especially in active yards or rental depots. Core tools for efficient track changes include a heavy‑duty floor jack or cribbing blocks, jack stands, a long pry bar, a ratchet strap or chain, a grease gun, the correct wrench or socket for the tensioner grease valve, a torque wrench, and cleaning tools for the adjuster cavity. Staging these tools before loosening the adjuster keeps the machine from sitting half‑disassembled and improves job efficiency.
How Do Cat Skid Steer Track and Undercarriage Components Work Together?
Cat skid steer and compact track loader undercarriages rely on a coordinated system of components to transfer torque and keep the machine stable. The sprocket drives the track by engaging the internal drive lugs, while the front idler guides and tensions the track, helping maintain straight tracking and smooth ride. Bottom rollers carry machine weight and define sag, and carrier or top rollers support the upper section of the track to prevent whipping and vibration.
The track adjuster cylinder, controlled by a grease fitting, moves the front idler in or out to set proper tension. Guard plates and access covers protect this mechanism from mud, rock, and debris, which is vital for long-term reliability. AFT Parts designs replacement sprockets, idlers, and rollers to integrate seamlessly with this system, matching OEM pitch and profiles to support smooth, consistent track engagement.
How Do You Safely Lift and Support a Cat Skid Steer for Track Changes?
To lift the machine safely, use the attachment and hydraulics only to position, not to support, the loader. Slightly raise the front of the Cat skid steer or CTL using the bucket, then place jack stands or cribbing blocks under manufacturer‑approved lift points or frame pads until the track being serviced is completely off the ground. The goal is stable mechanical support, not reliance on hydraulic pressure.
Always use stands or cribbing rated for the machine’s operating weight and inspect them for damage or distortion before use. Many Cat models include dedicated tie‑down or lifting eyes that function as ideal support locations. AFT Parts frequently advises fleet customers to standardize lifting equipment and training across sites, ensuring every technician follows the same proven safety baseline.
How Do You Release Track Tension on a Cat Skid Steer?
Track tension is controlled by a grease‑adjusted cylinder. To release tension, open the undercarriage access door on the side where the track adjuster is located, then thoroughly clean around the grease valve to keep contamination out of the system. Using the appropriate wrench or socket, slowly loosen or remove the grease fitting to allow grease to bleed from the adjuster.
As grease escapes, the front idler retracts and track tension drops. On heavily tensioned systems, it can help to apply moderate pressure to the front idler with a pry bar or to use a ratchet strap around the track and frame to encourage the idler inward as grease releases. Continue until you see noticeable sag between the bottom rollers and can pull the track away from the sprocket with moderate leverage.
How Do You Remove Cat Skid Steer Tracks Safely?
Once the track is fully de‑tensioned, begin removal at the sprocket. Insert a pry bar behind the track and, if safe and permitted, use the machine’s hydraulic drive at low speed to rotate the sprocket backward while you guide the track lugs off the teeth. A second technician should watch pinch points, monitor track movement, and communicate clearly with the operator in the cab.
After the lugs clear the sprocket, work the track off the rear roller, bottom rollers, and finally the front idler, supporting the heavy rubber section as it comes free. For larger Cat models, track removal tools or specialized clamps can reduce manual effort and improve control. Many AFT Parts customers standardize on two‑person teams for this stage to minimize strain and improve both safety and speed.
What Undercarriage Inspections Should You Perform Before Installing New Tracks?
With the track removed, the undercarriage is fully exposed for inspection. Check sprocket teeth for sharpness, hooking, or chipping; inspect idler and roller shells for cupping, flat spots, or cracks; and look closely at seals for oil leakage that suggests internal wear. Misaligned or bent components can quickly destroy a new set of tracks, so this is the ideal moment to correct underlying issues.
If sprockets or rollers are severely worn, replacing them alongside the new tracks usually costs less than prematurely damaging fresh rubber. AFT Parts offers complete undercarriage kits—including sprockets, idlers, and rollers—engineered to restore original geometry and reduce the risk of tracking problems. Matching new tracks with renewed undercarriage components maximizes both traction and service life.
How Do You Install New Cat‑Compatible Rubber Tracks?
Lay the new track beside the machine with the tread oriented in the correct direction of travel; most tread patterns are designed to shed mud and provide traction when installed in one specific orientation. Hook the track around the sprocket first, engaging several drive lugs, then gradually work it over the rear roller, bottom rollers, and finally the front idler using a pry bar and, if needed, a ratchet strap or track installation tool.
Slow, controlled sprocket rotation at low speed, combined with steady guidance by the ground technician, usually requires the least manual force. Ensure that the guide lugs seat cleanly in the roller and idler flanges and that no debris or foreign objects are trapped between components. Proper seating at this stage reduces the likelihood of derailment when the machine returns to heavy-duty work.
How Should You Set Track Alignment and Tension After Installation?
After the track is fully on, visually confirm that all guide lugs are centered between roller flanges and aligned on the sprocket. Reinstall the grease fitting and use a grease gun to pump grease into the adjuster, pushing the front idler outward and removing sag. Pause frequently to check sag at the midpoint between the bottom rollers; a modest, even sag is ideal for most Cat models.
Over‑tensioning creates excessive stress on bearings and seals, while under‑tensioning increases the risk of derailment and uneven wear. Once the tension looks correct, reinstall any guard plates or access covers. Many operators document sag measurements and grease strokes per adjustment as part of their maintenance logs, creating a repeatable baseline for future track changes across their fleet.
What Final Checks Ensure a Successful Cat Skid Steer Track Change?
When tension is set, remove jack stands or cribbing carefully and lower the machine to the ground. Start the engine and move forward and backward slowly, making gentle turns in both directions to help the new tracks seat fully on the sprocket, rollers, and idlers. After a short run, shut the machine down and recheck sag and alignment.
If the tracks appear too tight or too loose, adjust by releasing or adding small amounts of grease, reassessing until the desired sag is achieved. This final verification step is essential to prevent early edge wear, noise, or tracking issues. Organizations that work closely with AFT Parts often include a brief test loop and post‑inspection checklist in their standard operating procedures to confirm every change‑out meets internal quality standards.
What Safety Best Practices Apply During Cat Track Replacement?
Safe Cat track replacement depends on consistent habits, not just tools. Never work beneath a suspended machine without properly rated stands or cribbing; hydraulics alone should never be trusted for support. Keep hands, feet, and clothing clear of sprockets, rollers, and the underside of the track whenever the engine is running or the machine could move.
Clear communication is essential when two people are involved. Establish simple hand signals or radio calls between the operator and the ground technician before beginning. Avoid makeshift supports, improvised levers, or damaged ratchet straps, which can fail unexpectedly under load. In multi‑shift shops, lockout and tagout practices prevent other personnel from starting or moving the machine during a track service.
Which Replacement Track and Undercarriage Options Suit Different Cat Applications?
Choosing the right replacement track and undercarriage solution involves balancing cost, durability, and operating conditions. Premium Cat‑compatible tracks with reinforced steel cords and optimized tread patterns deliver long service life in heavy construction and rental environments. Standard‑duty tracks often suit lighter, mixed‑use fleets where operating hours and ground abrasiveness are moderate.
Undercarriage kits bundle tracks with rollers, idlers, and sprockets, providing a complete refresh for high‑hour machines or for preparing units for resale. Track replacement and mobile service providers add value by performing on‑site installations and inspections, helping busy contractors and municipal fleets cut downtime. AFT Parts supports these service models with matched components designed to work together as an integrated system.
Which Cat Track and Undercarriage Solutions Are Common?
How Do Cat OEM Tracks Compare to Aftermarket Options?
Many Cat skid steer owners weigh the trade‑offs between OEM tracks and aftermarket brands. OEM tracks are tailored precisely to Cat models and integrate seamlessly with factory warranties and support, often at the highest upfront cost. Premium aftermarket tracks are engineered to match OEM pitch and profiles but may use upgraded rubber compounds, steel cords, or tread designs tuned to specific applications.
Economy aftermarket tracks prioritize low purchase price, often with simplified internal reinforcement and more generic fitment across multiple machines. For professionals and rental fleets focused on cost‑per‑hour rather than just price per track, premium aftermarket options from suppliers aligned with AFT Parts can deliver strong value by extending service life and improving ride comfort.
How Do OEM and Aftermarket Cat Tracks Differ?
What Core Technologies Shape Modern Cat Skid Steer Tracks?
Modern Cat‑compatible rubber tracks combine multi‑layer rubber structures, continuous or overlapping steel cords, and precision‑molded tread lugs to handle heavy loads and harsh terrain. Wear‑resistant outer layers protect against abrasion and cuts, while more flexible inner compounds help reduce cracking and improve ride quality on uneven surfaces.
Steel cord reinforcement maintains pitch accuracy so the track meshes correctly with sprocket teeth even after thousands of hours. Advanced tread patterns balance traction, self‑cleaning in mud or snow, and reduced vibration at travel speeds. High‑quality guide lugs maintain alignment with rollers and idlers, decreasing the chance of derailment and sidewall damage under side loads.
How Do Track Tension and Wear Patterns Help Diagnose Problems?
Track tension is one of the most critical variables affecting track life and stability. Over‑tight tracks increase load on sprockets, rollers, and seals, causing heat buildup and accelerated wear. Under‑tight tracks tend to derail more easily, produce scalloped wear patterns, and may generate noise or vibration as lugs climb sprocket teeth under torque.
Common warning signs include excessive edge wear or chunking on one side, squealing or grinding from rollers, tracks walking off the idler, and visible oil leaks from seals. If these symptoms appear shortly after a track change, re‑evaluate sag, alignment, and the condition of track guards and guiding flanges. AFT Parts often recommends addressing bent or severely worn components promptly to avoid repeated issues.
How Can You Extend Cat Skid Steer Track Life?
Extending track life relies as much on operator habits as on component quality. Avoid unnecessary high‑speed travel on sharp gravel or rough concrete, especially when empty. Minimize aggressive pivot turns on abrasive surfaces by using wider arcs that reduce side loading on tracks and undercarriage components.
Keeping tracks clean is equally important. Washing off built‑up mud, concrete, or chemicals prevents long‑term rubber degradation and helps operators spot damage early. Machines should be parked on dry, level ground away from standing oil or solvents. Regularly checking and adjusting track tension to manufacturer guidance ensures the undercarriage operates in its optimal range, minimizing both wear and derailment risk.
What Future Trends Shape Cat Skid Steer Track Technology and Maintenance?
Future Cat skid steer and CTL undercarriage systems are moving toward smarter, more durable solutions. Improved rubber compounds and reinforcement technologies are increasing usable hours per track while better resisting cuts, heat, and UV exposure. Enhanced sealing and bearing systems in rollers and idlers are reducing maintenance intervals and contamination risk.
Emerging monitoring solutions track machine hours, undercarriage temperature, and load conditions, enabling more precise prediction of replacement windows. Frame geometry and track guide improvements aim to simplify removal and installation. AFT Parts continues to invest in these innovations, helping heavy equipment professionals adopt data‑driven maintenance strategies that reduce unscheduled downtime and stabilize undercarriage budgets.

FAQs About Cat Skid Steer Track Changes
How often should Cat skid steer tracks be replaced?Replacement timing depends on operating hours, terrain, and operator habits. Many professionals rely on visual inspection of tread depth, lug integrity, and visible cord damage rather than a fixed hour count, replacing tracks once traction drops or structural damage appears.
Should both tracks be replaced at the same time?In most cases, replacing both tracks together maintains balanced traction, predictable handling, and even wear on sprockets and rollers. Installing a single new track opposite a heavily worn one can create side‑to‑side differences and accelerate component wear.
Can a single technician change Cat skid steer tracks?A single experienced technician can perform the work with the right lifting equipment and tools, but a two‑person team is strongly recommended for safety and efficiency. One person can operate the machine while the other guides the track, communicates hazards, and manages tools.
Is it necessary to replace sprockets when installing new tracks?If sprocket teeth are sharp, hooked, or unevenly worn, they should be replaced during the same service. Running new tracks on severely worn sprockets accelerates lug wear, increases noise, and can cause tracking issues that shorten track life.
Can aftermarket tracks perform as well as Cat OEM tracks?High‑quality aftermarket tracks designed to match OEM pitch, profile, and materials can deliver comparable or even improved performance, especially when paired with precision undercarriage components from suppliers such as AFT Parts.
