Product Specifications
An excavator track link assembly is a crucial component of the undercarriage system in tracked excavators. It consists of several interconnected parts that work together to provide mobility, stability, and weight distribution. Below is a breakdown of its key components and functions.
Components of an Excavator Track Link Assembly:
Track Links (Chain Links) – Individual steel plates that interlock to form the track chain.
Track Pins – Hardened steel rods that connect the track links, allowing articulation.
Track Bushings – Sleeves that fit over the track pins, reducing wear between pins and links.
Track Shoes (Pads) – Attached to the links, they provide traction and distribute the machine’s weight.
Master Link (Master Pin & Bushing) – A special link used to connect/disconnect the track chain during maintenance.
Seals & Retainers – Prevent dirt and debris from entering the pin-bushing joint, extending lifespan.
Functions:
Provides mobility on rough or soft terrain.
Distributes the excavator’s weight to prevent sinking.
Absorbs shock loads during operation.
Ensures smooth movement via articulation between links.
Common Issues & Maintenance:
Wear & elongation (stretched tracks due to pin/bushing wear).
Broken or cracked links from excessive stress.
Seal failure, leading to dirt ingress and accelerated wear.
Track misalignment due to damaged components.
Replacement & Repair Tips:
Regularly inspect track tension and wear patterns.
Replace worn bushings and pins before they damage other components.
Use genuine or high-quality aftermarket parts for longevity.
Ensure proper track tension adjustment (too tight increases wear; too loose causes derailment).
