7134017 Arm Cylinder Seal Kit — Product Overview

The 7134017 Arm Cylinder Seal Kit is a precision aftermarket replacement for the Bobcat 430 compact excavator. Designed for the arm cylinder with 1-1/2″ rod and 2-1/2″ bore dimensions, this kit matches OEM cylinder numbers 6815009, 7121065, and 7134017 (S/N: 5630110-Up).

The Bobcat 430 is a 4-5 ton class compact excavator widely used in urban construction, utility work, and landscaping. The arm cylinder generates the digging force by pulling the bucket through the cut — operating under high cyclic loads and constant exposure to abrasive soil conditions. The 7134017 kit also cross-references to lift cylinder seal kit 7135559, expanding its application to Bobcat skid steer loaders (S175, S185, 773G).

Built with polyurethane rod seals for abrasion resistance, PTFE backup rings for extrusion protection, and NBR static seals etc, this kit delivers reliable performance across both excavator arm and loader lift cylinder applications. DJF Seals supplies this kit at factory-direct wholesale pricing.
