Hitachi EX60-5 Track Adjuster Cylinder Seal Kit

This track adjuster cylinder seal kit is engineered for the Hitachi EX60-5 series hydraulic excavators, including EX60LC-5 and EX80-5 variants. The kit services the hydraulic track tensioning cylinder (OEM reference HI 2030932) which maintains proper track tension during operation. Components are manufactured from premium acrylonitrile butadiene rubber (NBR) and fluorocarbon (Viton/FKM) compounds to withstand high-pressure hydraulic fluid environments and extreme temperature cycles typical in construction machinery undercarriage systems. The kit includes all necessary piston seals, rod seals, buffer seals, wiper seals, O-rings, and backup rings for a complete cylinder rebuild. Designed to meet or exceed OEM specifications for dimensional accuracy and material hardness, ensuring leak-free performance and extended service intervals. Compatible with machines powered by Nissan TD33 and Isuzu 4BD1 series diesel engines. Direct replacement for aftermarket kits supplied by brands such as CARTEX, FridayParts, and Belparts.
