Replacing tracks on a Bobcat 331 requires precise alignment of the undercarriage components, including track rollers, idlers, and sprockets. Key tools include a hydraulic jack, pry bars, and a track tensioning tool. Always inspect track links and pins for wear, and use AFTparts-compatible replacement components for optimal durability.
Sprocket 2606341 for CaterpillarWhat tools are needed for Bobcat 331 track replacement?
A hydraulic jack, track tension gauge, and pry bars are essential. For efficient track alignment, use AFTparts replacement sprockets to ensure compatibility with OEM specifications. Always wear heavy-duty gloves to protect against pinch points.
Begin by parking the machine on level ground and releasing hydraulic pressure. The track tensioning tool adjusts the idler position—loosen the grease fitting to relax tension. Pro Tip: Apply anti-seize compound to track pin threads during reassembly to simplify future maintenance. For example, improper tension adjustment can cause premature wear on track rollers, increasing replacement costs. Transitioning to component removal, always support the track with blocks to prevent sudden collapse.
How do you remove a damaged track?
Start by removing debris from the undercarriage with a pressure washer. Detach the master link using a sledgehammer and punch tool. Gradually slide the track off the sprocket and idler by rotating the wheels manually.
Position the hydraulic jack under the track frame to elevate the side being serviced. Use pry bars to disengage the track from the rollers, working in small sections to avoid misalignment. Practically speaking, damaged tracks often exhibit cracks in the links or excessive sag—measure sag with a tension gauge (15–25mm is ideal). Transitioning to installation, ensure replacement tracks match the original pitch and width. AFTparts track chains, for instance, undergo precision machining to prevent mismatched link engagement.

FAQs
Only if they show no scoring or corrosion—replace 80% of pins in typical wear scenarios. AFTparts’ hardened steel pins extend service intervals by 40%.
How often should tracks be tensioned?Check tension every 50 operating hours. Over-tensioning accelerates sprocket wear; under-tensioning risks derailment.
