Generally, correct track sag for smaller mini excavators should be about 2,5cm, while correct tension on larger rubber track machines should be about 5 cm.
How tight should skid steer tracks be?
Depending on measurements, tracks should be tightened or loosened as needed. Again, stick to 15 to 30 mm. If the tension is too tight, it can speed up the track wear on sprockets and idlers as well as require more effort to rotate the track.
How can you tell if rubber tracks are bad?
Signs you need to replace your rubber track
The tension of the track can swag and extend over time with heavy usage leading to a loss of traction as well. If cracks appear in the tracks, the track is worn. Cracks can be caused from heat. To prevent wear from heat, don’t park in direct sunlight.
How do you check the track tension on a track type machine?
The process of checking track tension is:
- Apply a specific amount of weight to the track midpoint – causing it to bend.
- Measure the deflection amount with weight applied.
- Reference your operation and maintenance manual to check that it is within the specified range.
How long do rubber tracks last?
Depending on how you treat them, the tracks could last as little as 400 hours or up to 2,000 hours. The average is somewhere between 1,200 and 1,600 hours.
What is better rubber tracks vs steel tracks?
Rubber tracks have a noticeable traction advantage over steel tracks on most surfaces. Rubber has a higher intrinsic friction and melds to uneven surfaces, increasing the overall surface area. On any relatively smooth, dry surface, rubber tracks will have the advantage.
When should I replace rubber tracks?

How long do excavator tracks last?
Most manufacturers recommend that the tracks on a mini excavator should be replaced every 1,500 hours of use, depending on application. However, the life of the tracks can extend beyond that time if the tracks are maintained properly throughout their use.
How long do rubber tracks last on a skid steer?
Depending on their quality, skid steer tires usually last between 600 and 1,000 hours. Rubber tracks last longer, between 1,200 and 1,600 hours.
How do you adjust the tension on a track?
Track tension is controlled by a track adjuster located behind the front idler. Tension adjustments are made by pumping or draining grease through the track adjuster valve. Even small adjustments in track sag have a big impact on tension. A change in sag from 1′ to 0.5′ increases tension by about 3,000 pounds.
Can rubber tracks be repaired?
Store Tracks Properly
If a machine has superficial cracks in the rubber, it can be repaired, but oftentimes the fix is only temporary. If the damage to the tracks is so severe that the inner steel cords have begun to break, the entire set will need to be replaced.
