1022316 Original Excavator TRACK-LINK for Hitachi ZX800

The original track link (track link) part number 1022316 is the core connecting component of the Hitachi ZX800 large excavator chassis system. It is specifically designed for ZX800 and ZX800-3 series models, and is precisely matched with drive wheels, guide wheels, and track shoes to form a walking mechanism. This universal number is its unique factory identification, ensuring precise matching with the host chassis system. When ordering, the complete model and serial number of the equipment must be provided for verification.

As shown in the actual product in the picture, this product is a track link forged from high-strength alloy steel. The key dimensions are identified and traced through characters such as "H 04 260F G L" laser engraved on the bottom. There are two large circular shaft holes distributed on the component for installing pin shafts and bushings; The two square holes in the middle are through holes for connecting bolts, used to fix the track shoes. The colored oxidation marks on the surface are a characterization of its special heat treatment process (such as quenching), which endows the product with extremely high surface hardness (usually>44HRC) and core toughness, capable of withstanding the huge impact and wear under heavy load operation.

Every 8-10 hours of daily work, the fastening status of the connecting bolts between the chain links and the track shoes should be checked, and the embedded gravel and soil should be cleaned. Measure the fit clearance between the pin shaft and the bushing every 500 working hours. If it exceeds 5mm, replacement should be considered. Regularly lubricate the chain link pin shaft through a grease nipple. When the tread surface of the chain link experiences severe wear (such as a height reduction of more than 30%), cracks, or deformation of the shaft hole, it must be replaced with original 1022316 parts in a timely manner, and it is recommended to replace them in pairs on the same side to maintain balance. Avoiding long-term overload operation under extremely harsh working conditions can effectively extend its service life.
