CR4424 Caterpillar D6H Bulldozer 39L Track Link Assembly
1. The chain piece has been forged, tempered and medium frequency -- scientific quenching process ensures that the core hardness of the chain piece is above HRC32, the hardness of the running rail surface is above HRC55, and it has a good metal structure.
2. Transfer to the machining workshop, where the chain piece raw material are first shot blasted, and then processed by special CNC processing equipment. Because the oil track link requires very high precision for the chain pieces, so as to ensure the sealing of the oil track link.
3. After processing, it is directly assembled with track link bushings, pins and other accessories. The stroke of each link is fixed during press-fitting, ensuring that the position of each link is consistent and the hole distance is the same.
4. Components are built with high grade steel and hardened for exceptional strength and wear life and work and wear as a system for maximum uptime and productivity.
