Track link assemblies form the structural backbone of the undercarriage — every load the machine generates passes through the chain. When pitch elongation, cracking, or bush wear reaches OEM replacement limits, fitting a new assembly with matched pin, bush, and link dimensions is the only way to restore undercarriage performance. This aftermarket track link assy 48l pc450-8 for the PC450-8 is manufactured to OEM pitch, link height, and section dimensions.

Why Choose This Track Link Assy 48L PC450-8
– Chain pitch and link height confirmed to OEM specification for correct engagement with sprocket and carrier rollers
– Pin and bush bore dimensions to OEM tolerances
– Link section confirmed to OEM for rated tensile and fatigue load capacity

Heavy-Duty Construction
This track link assy 48l pc450-8 is manufactured using alloy steel links: normalised and induction-hardened rail surfaces for wear resistance against roller contact. Sealed-and-lubricated (SAL) or press-fit pin/bush assembly where applicable. Master links included where required for full chain assembly. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Replace sprocket simultaneously with chain assembly
– Set track tension to OEM sag immediately after fitting
– Recheck tension and inspect master link after first 50 operating hours
