6810470: Hydraulic Cylinder Seal Kit for Bobcat Excavator 231 Bucket
6810470 Bucket Cylinder Seal Kit — Product Overview
The 6810470 Bucket Cylinder Seal Kit is a heavy-duty aftermarket replacement covering Bobcat 231, 329, 331, 331E, 337G, 337WG, and 341G excavators. With 2″ rod and 3-1/4″ bore dimensions, this kit matches OEM cylinder numbers 6812165 and 6818255, and cross-references to 7137966.
The bucket cylinder on these mid-size excavator models endures the machine’s highest structural loads — from breakout forces during digging to shock loads when encountering rock and hardpan. Seal failure leads to bucket drift (the bucket angle slowly changes under load), reduced digging precision, and hydraulic oil contamination from abrasive soil ingress. The 6810470 kit is built with polyurethane rod seals for maximum abrasion resistance in dirty environments, PTFE backup rings for extrusion protection under peak breakout pressure, and NBR O-rings etc for static sealing.
DJF Seals supplies this kit at factory-direct wholesale pricing. One kit supports 7 Bobcat models, simplifying parts inventory for multi-model fleet owners and equipment dealers.
