Properly tension rubber tracks by measuring sag (ideal 20-40mm or 1-1.5 inches between roller and track top), then adjusting the grease cylinder: pump grease if loose, bleed if tight. Park on flat ground, clean tracks first, and recheck after 5-10 hours of use. This prevents premature wear on CAT, Komatsu, Bobcat models—essential for Canadian contractors in Alberta oil sands or Ontario sites.

Why Is Proper Rubber Track Tension Critical for Excavator Performance?
Proper rubber track tension prevents derailment and spinning from loose tracks, common in BC forestry, and avoids accelerated wear on rollers and idlers from tight tracks, which can cost over $2,000 CAD in mini excavator repairs. It extends AFT rubber track life, reduces downtime for Quebec mining, and maintains 12-month warranty on OEM-spec parts for Kubota KX161 or Bobcat E35.
What Tools Do You Need for Rubber Track Tensioning?
Use a high-pressure grease gun (10,000 PSI), sag measurement ruler or straight edge, torque wrench, safety gear like gloves and chocks, and a cleaning brush. These tools work for Komatsu PC400 or Hitachi models with OEM-spec grease to prevent cylinder failure. AFT Parts offers compatible kits with free shipping across Manitoba to Newfoundland.
How Do You Prepare Your Excavator for Track Tensioning?
Park on flat, level ground essential for accurate sag in Saskatchewan prairies, engage safety lock, and clean tracks and undercarriage of mud and rocks. For mini excavators like Bobcat or Yanmar, lift slightly with the bucket. Always chock tracks and warn workers to prevent injuries during rental fleet maintenance in Alberta.
What Is the Correct Way to Measure Rubber Track Sag?
Place a ruler perpendicular between the bottom roller and track top at the center, targeting 20-40mm sag; consult manuals for Doosan or JCB variances and take photos for records. Adjust for terrain like softer Quebec soils. Use this method on AFT Parts rubber tracks such as 300x52.5Nx80 for Bobcat models.
| Machine Brand | Ideal Sag (mm) | Common Issue if Off |
|---|---|---|
| CAT D6R | 25-35 | Loose: Dehiscence in oilsands |
| Komatsu PC400 | 30-40 | Tight: Idler wear |
| Bobcat E35 | 20-30 | Mini: Spinning on slopes |
| Kubota KX161 | 25-35 | Forestry: Mud buildup |
How Do You Adjust Track Tension Using the Grease Cylinder?
If sag exceeds specs, attach a grease gun to the cylinder valve and pump slowly (1-2 strokes per minute) until reaching 20-40mm, monitoring pressure on John Deere models. For overtight tracks, open the relief valve to bleed excess grease, collecting waste for Nova Scotia eco-compliance. Recheck after adjustments.
What Are Common Mistakes in Excavator Rubber Track Tensioning?
Avoid over-tensioning, which voids AFT's 12-month pro-rated warranty, ignoring brand specs like 15-25mm for Ditch Witch minis, and skipping rechecks after 10 hours. For rental Bobcats, adjust in cooler temps. Choose AFT's OEM-spec rubber tracks like 300x52.5Nx80 for $999.99 CAD with Canada-wide shipping for easier maintenance.
How Often Should You Check and Retension Rubber Tracks in Canada?
Perform daily visual checks for high-use Alberta mining, weekly full inspections, and retension after 5-10 hours or terrain changes like BC rocky sites. Loosen 5mm in New Brunswick winters for freeze-thaw. Pair with AFT sprockets and repair kits; join the dealer program for bulk pricing across provinces.
