Track link replacement is a precision job — the replacement link must match OEM pitch exactly or it disrupts the engagement relationship with the sprocket across the splice point. This aftermarket master pin-track link 349d is manufactured to OEM pitch, height, and section specifications for the 349D for a structurally sound, correctly engaging replacement.

Why Choose This Master Pin-Track Link 349D
– Pitch: matches OEM chain pitch for this machine — confirmed to engineering drawing
– Rail surface: OEM height and width for correct carrier and track roller contact geometry
– Bore: OEM dimension for correct pin press-fit

Heavy-Duty Construction
This master pin-track link 349d is manufactured using alloy steel, carburised and case-hardened rail surface. Core toughness prevents brittle fracture under impact loads. Dimensional inspection before packaging. 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
– Use new pins and bushes — never reuse worn bores for a new link
– Verify assembly pitch uniformity around the replaced section after fitting
– If more than 3 consecutive links are cracked, assess for full chain replacement
