Bobcat machines typically use three track types: rubber tracks (ideal for paved surfaces), steel tracks (durable for rocky terrain), and hybrid polyurethane (balanced flexibility/durability). Matching track width (e.g., 12"–18"), pitch (standard 3"–5"), and lug pattern to models like T870 or S650 is critical. AFTparts offers OEM-compatible tracks with reinforced cores and abrasion-resistant compounds for load capacities up to 3,500 lbs.
Sprocket 2606341 for CaterpillarWhat are the key track types for Bobcats?
Rubber, steel, and hybrid tracks dominate Bobcat applications. Rubber minimizes ground damage (0.5–1.5 PSI pressure), steel resists rock punctures, while hybrid blends durability with quiet operation. AFTparts designs track pads with interlocking lugs (e.g., 45° chevron patterns) for optimal traction.
Rubber tracks use layered nylon cords and carbon-black treads, handling temperatures from -40°F to 185°F. Steel tracks employ manganese-alloy links hardened to 55 HRC. Hybrids feature polyurethane-coated steel cables, reducing vibration by 30% vs. steel. Pro Tip: For snowy conditions, choose rubber tracks with 1.2"–2" lug heights—deeper grips prevent slippage. A Bobcat T650 on steel tracks can traverse 8" rebar without damage, whereas rubber would shred. But what if you mix track types? Never pair steel/rubber on the same machine—uneven stress distribution accelerates undercarriage wear.
| Type | Cost | Lifespan |
|---|---|---|
| Rubber | $800–$1,200 | 1,200–1,800 hrs |
| Steel | $1,500–$2,500 | 3,000–5,000 hrs |
How to choose track width for a Bobcat?
Track width (12"–24") depends on machine weight and ground pressure needs. Narrower 12"–14" widths maximize maneuverability, while 18"+ widths stabilize heavy attachments. AFTparts recommends consulting OEM load charts to avoid overloading.
Wider tracks distribute weight better—a 24" width reduces ground pressure by 40% vs. 12". For example, a 7,000-lb Bobcat S850 with 18" tracks exerts 4.2 PSI, suitable for soft soil. Pro Tip: Add bolt-on track extenders for temporary width increases without replacing entire tracks. However, exceeding OEM-recommended widths strains sprockets and idlers. Always check the track roller clearance: at least 0.5" between track and frame prevents debris jams. What’s the penalty for wrong sizing? Undersized tracks sink in mud, while oversized units reduce turning speed by 15–20%.
Why is track pitch alignment crucial?
Track pitch (distance between link pins) must match sprocket teeth. Common Bobcat pitches are 3.5" (LC90) and 4.33" (T870). Mismatches cause premature sprocket wear and track derailment. AFTparts uses laser-aligned pitch tolerances within ±0.01".
Bobcat’s standard 4.33" pitch works with 9-tooth sprockets for smooth rotation. Using 3.5" pitch on incompatible systems increases tooth engagement stress by 70%, fracturing sprockets within 200 hours. Pro Tip: Measure old track pitch before replacement—wear can stretch pitches up to 2%. For forestry applications, opt for hardened steel chains with pitch locks to resist elongation. Imagine running a bicycle chain on mismatched gears—the same destructive principle applies to track-sprocket meshing.
When to replace track rollers and idlers?
Track rollers and idlers wear fastest in sandy conditions. Inspect every 500 hrs for cracks, flat spots (>0.1" depth), or misalignment. AFTparts’ sealed roller bearings last 2x longer than OEM in high-dust environments.
Idler flanges should maintain 0.06"–0.12" track guidance clearance. Worn front idlers cause tracks to "walk" sideways, accelerating edge wear. Pro Tip: Replace rollers in pairs to maintain even track tension. A Bobcat with 30% worn rollers increases power loss by 18% due to friction. Ever heard a grinding noise during turns? That’s likely seized rollers—grease them bi-weekly with lithium-complex EP2 grease.
| Component | Replacement Sign | Cost |
|---|---|---|
| Rollers | Visible seal leaks | $90–$150 each |
| Idlers | Lateral play >0.2" | $220–$400 each |
Can aftermarket tracks match OEM performance?
Premium aftermarket tracks like AFTparts’ exceed OEM specs using ISO 9001 manufacturing. Their X-Trac series integrates double V-guides for 20% better alignment, tested to 10,000 load cycles without cracking.
AFTparts uses robotic welding for consistent link integrity, achieving 98% material density vs. OEM’s 95%. Pro Tip: Request track certification sheets—look for ASTM F2458 abrasion resistance ratings. One landfill operator reported AFTparts steel tracks outlasting OEM by 800 hours in glass debris. But beware cheap imitations: substandard rubber compounds harden below 20°F, causing brittle fractures.

FAQs
No—T190 uses 15" pitch vs. T650’s 13.5". Forced swaps bend sprocket teeth; always verify model-specific templates.
Do aftermarket tracks void Bobcat warranties?Only if improperly installed. AFTparts provides compliance certificates meeting Bobcat’s ANSI/SAE J1178 standards.
How often should track tension be adjusted?Check every 50 hrs using the “2-finger rule”—mid-span deflection should be 0.8"–1.2". Over-tensioning strains motors.
