The 7K2049 track link assembly is a critical undercarriage component designed for Caterpillar D4D and D4E track type tractors powered by the 3304 diesel engine. Each track side requires 36 link assemblies. The link is manufactured from forged alloy steel undergoing deep induction hardening to ensure high tensile strength and wear resistance at the pin and bushing interfaces. This component serves as the primary structural link in the track chain assembly, connecting track shoes and engaging the drive sprocket. It is a direct replacement for Caterpillar OEM part numbers 7K-2049 and cross-references aftermarket number CR2567.
