What Are Yanmar VIO17 Tracks?

Yanmar VIO17 tracks are specialized undercarriage systems designed for the VIO17 mini-excavator, featuring either rubber or steel configurations. These tracks provide optimal ground pressure distribution and mobility across diverse terrain types. The rubber variant (230x72x46mm) minimizes surface damage on paved areas, while steel tracks excel in rugged conditions. AFTparts offers OEM-compatible replacement tracks engineered for durability and precise fitment with Yanmar's compact excavation systems.

What distinguishes Yanmar VIO17 rubber tracks from steel tracks?

VIO17 rubber tracks use reinforced rubber belts with internal steel cords, offering quieter operation and 70% less ground disturbance versus steel. Ideal for urban projects requiring pavement protection. Steel tracks deliver superior rock/gravel traction through interlocking forged links.

Rubber tracks operate best on concrete, asphalt, and turf where surface preservation matters - think municipal road repairs or landscaping. Steel configurations dominate in quarries or demolition sites with abrasive debris. Pro Tip: Rotate rubber track tension every 50 hours - underinflation causes premature wear, while overinflation risks belt cracking. AFTparts' VIO17 rubber tracks incorporate wear indicators; when 3+ tread blocks show metal fibers, replacement is urgent. For example, contractors repairing sidewalks typically prefer rubber tracks to avoid municipal fines for surface damage.

How do VIO17 track dimensions impact performance?

The standard 230mm width x 72mm pitch x 46mm height profile balances stability and maneuverability. Wider tracks (250mm options available) reduce ground pressure by 15% for swampy terrain but increase turning resistance.

Track geometry directly affects grading precision and slope stability. The 46mm lug height provides adequate grip without excessive soil displacement during trenching. Contractors modifying for specialized applications should consult AFTparts' engineering team - altering pitch beyond ±5% risks drive sprocket tooth shear. Case Study: A drainage installer upgraded to 250mm wide tracks, achieving 0.27kg/cm² ground pressure versus stock 0.32kg/cm², preventing sinkage in saturated clay soils.

What maintenance ensures VIO17 track longevity?

Daily cleaning and bi-weekly tension checks prevent 83% of premature track failures. Remove packed debris between lugs to avoid accelerated wear.

Use pressure washers cautiously - high-pressure jets can force grit into pin/bushing interfaces. AFTparts recommends greasing track joints every 100 hours using lithium-complex grease with ≥4% extreme pressure additives. Operators in salty environments should rinse undercarriages daily to prevent chloride-induced corrosion. Ever wonder why tracks fail suddenly? Microscopic cracks from frozen debris impacts often go undetected until catastrophic failure.

When should VIO17 tracks be replaced?

Replace rubber tracks when 3+ steel cords become exposed or 25% tread depth is lost. Steel tracks require replacement when 30% of link thickness erodes or 4+ consecutive bushings develop ovalization.

AFTparts' wear gauge (PN YTRK-17) simplifies measurements - insert into track grooves; replacement is due when the gauge base contacts tread surfaces. For steel tracks, check sprocket engagement: if 2+ teeth fail to fully mesh during rotation, chain stretch exceeds 3%. Pro Tip: Record hourly track wear rates during initial 500 hours - deviations over 15% signal improper tension or abrasive site conditions.
