Worn or stretched track links allow pitch elongation that causes chain to hop sprocket teeth — accelerating sprocket wear and increasing de-tracking risk. This loose link 203-32-51123/33 / pc100-5 is manufactured to OEM pitch and pin bore specification for correct sprocket engagement and chain tension.

Why Choose This Loose Link 203-32-51123/33 / PC100-5
– OEM pitch dimension maintained to tight tolerance
– Pin bore diameter and surface finish matched to OEM for correct press-fit without bore damage
– Rail surface hardened for correct roller and idler contact wear resistance

Heavy-Duty Construction
This loose link 203-32-51123/33 / pc100-5 is manufactured using forged high-carbon alloy steel: correct fatigue resistance at the pin boss and shoe bolt holes. Induction-hardened rail surface for roller wear resistance. Shoe bolt holes drilled and tapped to OEM pitch and thread specification. 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
– Measure existing chain pitch before ordering replacement links
– Replace link sets in full chains where possible
– Set correct chain tension after fitting; inspect and adjust after first 50hrs of operation
