Product Overview

The 6803281 hydraulic cylinder seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Bobcat part number 6803281. The Bobcat Company store itself titles the number “Blade Cylinder Seal Kit 6803281,” and independent parts listings fit the number to the Bobcat 320D / 320G / 322D / 322G and X320 compact excavators: Hercules Sealing Products lists it as BCK-6803281 with a 1.375 in. rod x 2.375 in. bore for the 320D / 320G / 322D / 322G blade cylinder, and the same 1-3/8 x 2-3/8 in. figures appear at zerksplus, hydrauliccylindersinc and in eBay / tornadoparts listings. The current DJF page titles the kit for the 320D / 320G / 322D / 322G / X320 blade and boom repair (see Fitment Verification for position and dimension conflicts).

DJF Seals manufactures and supplies the 6803281 kit at factory-direct wholesale pricing for Bobcat compact excavator dealers, repair shops and fleet maintenance programs.

Verified Application

The following application data was cross-checked against the Bobcat Company store product title and aftermarket parts listings (Hercules Sealing Products, zerksplus, hydrauliccylindersinc, theoringstore, eBay, tornadoparts):

Materials, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified for this part number; such claims on the current page are not repeated here (see Fitment Verification).

Replacement Scope

This kit supplies the sealing elements needed to reseal the cylinder it is matched to on the verified Bobcat models. For the 320D / 320G / 322D / 322G family the OEM store title and Hercules name the blade cylinder (Hercules: cylinder 6810615); for the X320 the listings span the arm, blade and boom cylinders. Because the position wording differs by model and by seller, the cylinder position and its casting / cylinder reference must be confirmed before shipment.

Fitment Verification

The part number, fitments, position wording and dimensions above were cross-checked against the following sources:

• Bobcat Company store (shop.bobcat.com): the product title reads “Blade Cylinder Seal Kit | 6803281 | Bobcat Company” — OEM-level confirmation that Bobcat sells the number for the blade cylinder (the full OEM page was not accessible in this review).
• Hercules Sealing Products (herculesus.com, BCK-6803281): hydraulic seal kit, rod 1.375 x bore 2.375; blade application for the 320D / 320G / 322D / 322G with cylinder 6810615 and listed serial ranges (including 223811001-up, 223911001-up, 223511001-up and 224011001-up); X-320 lines for arm cylinder 6588297, blade cylinders 6587000 / 6802713, and boom cylinders 6587019 / 6589360 / 6803045.
• zerksplus: blade / arm / boom kit titled for the Bobcat 320D / 320G / 322D / 322G / X320, 1-3/8 rod x 2-3/8 bore.
• hydrauliccylindersinc: blade cylinder seal kit 6803281, 2.375 in. bore x 1.375 in. rod, for the 320D / 320G / 322D / 322G / X-320.
• theoringstore: X-320 boom cylinder seal kit under this number (title-level evidence in this review).
• eBay and tornadoparts: 6803281 with 2.375 in. bore, fits Bobcat excavators.
• Conflict note: cylinder-position wording conflicts across sources — the OEM store title and Hercules name the blade cylinder for the 320D / 320G / 322D / 322G family, while the X320 coverage spans arm, blade and boom cylinders (theoringstore: boom; Hercules X-320 rows: arm / blade / boom; zerksplus: blade / arm / boom; the current page: blade and boom). Position is therefore kept as wording and must be verified against the machine.
• Conflict note: the current page lists metric dimensions (blade cylinder Ø80 / Ø45 mm; boom cylinder Ø110 / Ø60 mm) that conflict with the 1.375 x 2.375 in. (approx. 34.9 x 60.3 mm) figures given by Hercules, zerksplus, hydrauliccylindersinc and eBay / tornadoparts. The copy above follows the independent inch figures; the metric figures on the page are not asserted.
• Conflict note: casting marks (BT-5G, BM-7D), the 325D exclusion (with 6811005) and the “pre-2016 320C” note are page data with no independent confirmation in this review and are not asserted.
• Materials, pressure, temperature, exact piece counts, certifications and service life are not independently verified.
