New 463-9336 Track Link As (1) is a direct replacement for the former 398-5234 Track Link As (SRL).

New 433-6739 Sprocket Segment (2) replaces former 278-2374 Segment and must be used with the 463-9336 Track Link As.

New track link assembly and new sprocket segment are adaptable to the products within the listed serial numbers.
