Key Benefits for Owners& Operators

• Superior Durability- Resists cracking, abrasion, and seizing in rocky, muddy, or debris-filled sites,extending undercarriage life by 40-60%.
• Cost-Effective Performance- Reduces track/sprocket/idler wear, lowers fuel consumption, and minimizes repair frequency.
• Easy Bolt-On Installation- No modifications required.
• Smooth Operation- Maintains proper track alignment and tension, reducing vibration for better control and operator comfort on slopes or confined areas.
• Proven Compatibility- Direct fit for Bobcat X337/X341/X435 rubber-track models.

Maintenance Tips for Longevity

• The "Daily Shake-Down": Always clear out packed mud and debris at the end of the shift. Hardened mud acts as an abrasive between the roller and the track link, causing premature wear.

• Monitor Track Tension: A track that is too tight places excessive upward pressure on the roller bearings. Always maintain the "sag" recommended in your Bobcat service manual.

• Watch for "Flat Spots": If a roller stops turning due to debris or bearing failure, the track will slide over it and wear a flat spot. A flat roller must be replaced immediately to prevent damaging your expensive tracks.

• Check for Oil Moisture: A "wet" look around the roller hub indicates a failing seal. Replacing the roller early prevents the internal shaft from seizing, which can cause significant undercarriage damage.
