When a track link cracks or fractures, the correct response is an immediate like-for-like replacement with an OEM-dimensioned part — otherwise the stress concentrates on adjacent links, accelerating chain failure. This aftermarket pin-track link 349d for the 349D replicates OEM pitch, link section, and rail geometry.

Why Choose This Pin-Track Link 349D
– Pitch: OEM specification for the 349D chain assembly
– Rail height and section width: OEM geometry for correct roller and sprocket contact
– Bore dimensions: confirmed to OEM for press-fit pin installation

Heavy-Duty Construction
This pin-track link 349d is manufactured using alloy steel: case-hardened rail surfaces, tough core. Machined rail faces for dimensional accuracy. Cleaned and inspected before dispatch. 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 both pin and bush with any link replacement — worn bores compromise the new link
– Inspect surrounding links for fatigue cracks when replacing a failed link
– If multiple links are damaged, consider a full chain assembly replacement
