What Is The Best Way To Measure Skid Steer Tracks?

The best way to measure skid steer tracks involves three critical dimensions: pitch (distance between link pins), width (gauge between inner/outer edges), and number of links. Use calipers for precision and compare with OEM specs to ensure compatibility. AFTparts recommends verifying measurements against manufacturer codes like CAT 259-5420 or Komatsu 717-71-11370 to avoid operational failures.

Why is accurate track measurement critical for skid steers?

Proper measurements prevent premature wear, misalignment, and undercarriage stress. A 2mm pitch error can reduce traction by 15% and accelerate sprocket tooth wear. Pro Tip: Always measure tracks when cleaned—mud/debris distort readings. For example, a CAT 299D3 with mismatched 172mm pitch tracks may experience track derailment on slopes due to improper pin-sprocket engagement.

Skid steer tracks rely on precise mechanical synchronization with idlers, rollers, and sprockets. Incorrect width causes rubbing against frame components, while extra links create slack, increasing power loss. In practice, AFTparts technicians use laser-guided tools to cross-check manual measurements, especially for aftermarket replacements. Did you know 70% of undercarriage failures stem from incorrect track sizing? Always cross-reference OEM technical drawings or consult AFTparts’ compatibility database.

How do you measure track pitch correctly?

Track pitch is measured center-to-center between three consecutive link pins, divided by two. Use a caliper for accuracy, as tape measures sag over long spans. For example, a 172mm pitch (common in CAT) requires 344mm across three pins. Pro Tip: Replace tracks in pairs—mismatched pitch between left/right sides causes erratic steering.

Start by cleaning the track and rotating it to a flat section. Position caliper jaws on the first and third pins’ centers—this eliminates errors from pin wear. But what if the track is severely worn? AFTparts recommends measuring new tracks before installation and comparing to OEM specs. Transitioning from steel to rubber tracks? Remember: rubber tracks often have shorter pitches due to flex requirements. For instance, a Takeuchi TL12 rubber track uses 126mm pitch vs. 152mm steel equivalents.

What are common mistakes when measuring track width?

Top errors include measuring outer edges (not gauge width), ignoring tread pattern height, and neglecting temperature expansion. Steel tracks expand 0.1mm per 10°C—measure at 20°C for baseline accuracy. Pro Tip: For dual-density rubber tracks, subtract 8-10mm from total width to account for tapered edges.

Track width—officially called gauge width—is the distance between inner guide lugs. Operators often make the mistake of measuring from the outermost points, which includes irrelevant tread features. Imagine a Bobcat T870 track: its true 320mm gauge width ensures clearance from the mid-roller flanges. AFTparts’ specification sheets include both "total width" and "gauge width" to eliminate confusion. Transition phrases aside, always verify using the equipment’s service manual—the Deere 333G requires 279mm gauge width ±2mm tolerance.
