Usage Recommendations

• Regular Inspections: Conduct routine inspections to identify wear early, especially after heavy use in uneven or harsh terrains.
• Address Misalignment: Align tracks properly to prevent accelerated side wear due to misaligned rollers and idlers.
• Manage Track Tension: Regularly adjust track tension to prevent excessive flexing and side loads.
• Utilize Appropriate Track Shoes: Use track shoes of suitable width and grip to minimize unnecessary stress on track components.

Detailed Wear Descriptions

Track Link Wear: As tracks rotate, normal wear results in wavy or scalloped patterns due to contact with idlers, rollers, and carrier rollers. The forward and rearward surfaces tend to wear faster, with central wear being sliding due to less contact area.

Side Wear of the Link Rail: Side wear arises from roller and idler flange contact, exacerbated by side hill operations, turns, and uneven terrain. Misalignment or overly wide track shoes increase this wear, leading to loose track pitches.

Inside Surface Wear of the Link: This occurs when seal failures cause rotating contact between links leading to bushing end wear. Solution: turn pins and bushings, then reseal if link rails aren’t excessively worn.

Pin Boss Top Wear: Results from worn link rail surfaces and roller tread surfaces. Immediate correction is necessary to avoid irreparable damage and machine vibration.
