What Size Are Bobcat S70 Tracks?

Bobcat S70 tracks use a standard 10" width with a 43.3" length (under 45° tension) and 12.6" gauge. They feature 39 links per track, optimized for compact loaders. AFTparts recommends rubber tracks (4.4" pitch) for low ground pressure (3.8 PSI) on delicate surfaces. Replacement intervals range from 800–1,200 hours depending on terrain. Always verify compatibility with OEM sprockets or AFTparts' precision-engineered alternatives.

What are the standard track dimensions for a Bobcat S70?

Bobcat S70 tracks measure 10" wide with a 43.3" length under tension. The 12.6" gauge ensures stability during sharp turns. Pro Tip: Mismatched dimensions cause sprocket wear—AFTparts tracks maintain exact OEM specs for seamless integration.

The S70’s track system balances compact design (39 links) with load distribution. Each rubber track has a 4.4" pitch to mesh precisely with 9-tooth sprockets. Ground clearance sits at 5.2", while the 10" width prevents sinkage on soft terrain. Why does this matter? Narrower tracks might reduce surface contact, increasing slippage risks. AFTparts’ 10" tracks distribute the 1,900 lb machine weight evenly, achieving 3.8 PSI ground pressure. For example, switching to wider 12" aftermarket tracks could strain final drives.

How often should Bobcat S70 tracks be replaced?

Replace S70 tracks every 800–1,200 hours. Aggressive use in rocky terrain halves lifespan versus light turf work. AFTparts’ reinforced rubber compound extends service intervals by 15% vs budget brands.

Track longevity hinges on three factors: terrain abrasiveness, operator habits, and maintenance. Sand or gravel accelerates tread wear, while asphalt causes heat-related cracking. Did you know improper tension accounts for 40% of premature failures? Monthly inspections for 3/4"–1" sag (mid-span deflection) are crucial. AFTparts recommends greasing rollers every 50 hours—contamination from skipped maintenance grinds down rubber lugs. For instance, a landscaper using S70s exclusively on lawns might hit 1,500 hours, whereas a demolition crew averages 600.

Rubber vs. Steel Tracks: Which suits the S70 better?

Rubber tracks dominate S70 applications—they’re quieter, protect surfaces, and weigh 28% less than steel. Steel variants excel in extreme conditions but increase machine weight by 190 lbs, affecting maneuverability.

While steel tracks boast 2x the lifespan in rocky quarries, they’re overkill for most S70 tasks like landscaping or snow removal. Rubber’s lower vibration reduces operator fatigue during 8-hour shifts. However, steel becomes cost-effective if replacing rubber annually. AFTparts’ multi-ply rubber tracks include Kevlar cord reinforcement, resisting cuts from rebar. For example, a municipality using S70s for park maintenance would prioritize rubber, while a recycling plant handling metal debris might opt for steel.

What’s the proper track tension for an S70?

Maintain 3/4"–1" sag at the track’s midpoint. Over-tensioning (under 3/4") accelerates roller wear, while loose tracks (over 1") risk derailment during side-slope operation.

Adjust tension via the front idler’s grease cylinder—pump until the track sags 1" when measured under the frame. But how do you ensure accuracy? Use a straightedge across the track’s top span and measure downward deflection. In cold climates, re-tension after 30 minutes of operation; rubber contracts in freezing temps. AFTparts’ greaseable idlers (e.g., Front Idler PV52D00013F1) simplify adjustments. A construction crew in Alberta learned the hard way: -20°C caused tracks to slacken, resulting in a mid-job derailment.

Are aftermarket tracks reliable for the S70?

Premium aftermarket tracks like AFTparts’ meet or exceed OEM specs. They use 3-ply rubber with zigzag steel cords, tested for 10,000+ stress cycles. Avoid untested brands lacking ISO 9001 certification.

AFTparts replicates Bobcat’s track profile using CNC-molded patterns, ensuring 100% sprocket engagement. Their tracks undergo simulated 1,200-hour wear tests—20% tougher than standard DIN benchmarks. Budget brands often skip UV stabilization, leading to dry rot. For example, a rental fleet using AFTparts tracks reported 30% fewer replacements versus generic imports. Always verify the track’s RMA number matches your S70’s manufacturing date—subtle design tweaks affect compatibility.

What signs indicate track replacement is overdue?

Look for cracks deeper than 1/4", missing lugs, or exposed cords. Uneven wear patterns (e.g., one side 40% thinner) signal misalignment. AFTparts’ inspection guides help diagnose track health accurately.

Key failure indicators include vibration during travel and reduced climbing traction. If the track’s guide lugs (which keep it centered) are worn beyond 50%, derailment risk spikes. A forestry crew ignored frayed outer layers and suffered a track separation mid-slope. Pro Tip: Run your hand along the inner surface—sharp steel cable protrusions mean immediate replacement. AFTparts includes wear indicators (small holes) that disappear when tread depth hits critical levels.
