PM620 Milling Machine Track Chain 383-4239 20 Link Undercarriage Assembly 90kg Replacement

This track chain is an aftermarket replacement assembly built for PM620 cold planer undercarriage systems. Each chain is supplied as a complete 20-link assembly with track pad fixing chain hardware, so the machine can be returned to work quickly after wear or impact damage in asphalt milling operations.

• Direct-Fit Track Chain Assembly: The 20-link configuration matches PM620 undercarriage geometry, requiring no modification during installation.
• Track Pad Fixing Chain Hardware: Pins and fixing chain are supplied together with the link assembly, reducing downtime and the risk of mismatched parts.
• Heat-Treated Link & Bushing Interface: Induction-hardened pin and bushing surfaces resist abrasion and elongation under continuous milling load.

Suitable for undercarriage repair of asphalt cold planers working on highway resurfacing, municipal road maintenance and airport runway milling projects. The assembly is a wear item and is normally replaced in pairs for even track tension.

Each chain is wrapped in anti-rust film, fixed on a wooden pallet and secured with steel strapping. Sea-worthy export packing is available for full container and LCL shipments.
