6817183: Boom Hydraulic Cylinder Seal Kit for Bobcat Excavator 337G, 337WG, 341G
6817183 Boom Cylinder Seal Kit — Product Overview
The 6817183 Boom Cylinder Seal Kit is a precision aftermarket replacement for Bobcat 337G, 337WG, and 341G excavators. Designed for the boom cylinder — the primary lifting mechanism on these 30+ ton class machines — this kit matches OEM cylinder specification 6818252 (after S/N: 234711001) and cross-references to 6817183.
The 337G and 341G are Bobcat’s largest excavator models, designed for heavy construction, quarry, and demolition applications. Their boom cylinders operate under extreme structural loads — lifting buckets weighing several tons through continuous production cycles. Seal failure on these machines results in boom drift, reduced lifting capacity, and costly downtime. The 6817183 kit uses high-grade polyurethane for the main rod seal, PTFE backup rings for extrusion resistance under maximum lift pressure, and NBR static seals etc for reliable long-term containment.
DJF Seals supplies this kit at factory-direct wholesale pricing — serving large excavator repair centers, mining support contractors, and international heavy equipment parts distributors.
