FAQs

Q: What is the purpose of the Track Adjuster/Recoil Spring Assembly EC200?

A: The Track Adjuster/Recoil Spring Assembly EC200 is a vital component in heavy machinery, specifically excavators like the EC200.

Its primary function is to maintain proper tension on the track, ensuring optimal performance and stability during operation.

Q: How does the Track Adjuster/Recoil Spring Assembly EC200 work?

A: The assembly consists of a recoil spring housed within a track adjuster cylinder. As the excavator moves and the track experiences wear, the tension in the track may decrease. The recoil spring exerts force against the track adjuster cylinder, which in turn adjusts the tension in the track, keeping it properly tensioned for

smooth operation.

Q: What are the signs of a malfunctioning Track Adjuster/Recoil Spring Assembly EC200?

A: Signs of a malfunctioning assembly include uneven track tension, excessive track sagging, increased track wear, and instability during operation.

Any unusual noises or vibrations from the undercarriage may also indicate issues with the assembly.

Q: How often should the Track Adjuster/Recoil Spring Assembly EC200 be inspected or serviced?

A: Regular inspection and maintenance of the assembly are essential for optimal performance and longevity of the excavator.

It is recommended to inspect the assembly during routine service intervals specified by the manufacturer,

typically every 250 to 500 operating hours, depending on operating conditions and usage intensity.
