BONOVO Undercarriage Parts Track Adjuster Assy Track Tensioner
Track adjuster or tensioner also called track adjuster cylinder which is used onto excavators and bulldozers.
Available for all brands and models of excavators, Hitachi, Komatsu, Caterpillar and other types of excavator crawler regulators.
A track adjuster assembly consists of a recoil spring, cylinder and a yoke.
Features
Tensioner for construction machine also could be called Recoil Spring Assembly.
It is consist of hydraulic system, recoil spring and connection parts.
Exclusive seal group ensure no oil leakaging, providing a stable status of hydraulic system for any working conditions.
The application of automatic in furnace roll-over device in roller hearth electric furnace can make the burning of material well-proportioned, as a result the finished spring performs more stable.

Testing

Check Your Track Tension Regularly
Operate the machine for at least a half hour to allow the track to acclimate to the working area before you check and set the track tension. If conditions change, like additional rainfall, readjust the tension. Tension should always be adjusted in the working area. Loose tension causes whipping at higher speeds, resulting in excessive bushing and sprocket wear. If the track is too tight, it causes stress on the undercarriage and drive train components while wasting horsepower.
Incorrect track tension may lead to increased wear, so it is important to adhere to the proper tension. As a general rule, when your operators are working in soft, muddy conditions, it is recommended to run the tracks slightly looser.
"If steel tracks are too tight or too loose, it can quickly accelerate wear,” “A loose track could cause the tracks to de-track."
