Product Overview

The YA00006596 hydraulic cylinder seal kit is a rebuild set supplied by DJF Seals for the boom cylinders of Hitachi ZX330-series excavators. YA00006596 is a genuine Hitachi part number listed as “KIT;SEAL” by parts databases including AVSpare, FinditParts and TraceyTruckParts, and the John Deere official store lists FYA00006596 as the original seal kit behind the John Deere substitute number 4S00783. The kit covers the sealing elements of one boom cylinder — rod seals, piston seals, wipers, wear guidance components, backup rings and O-rings as applicable. DJF Seals supplies it factory-direct for heavy-equipment parts distributors, repair shops and fleet maintenance teams.

Verified Application

Boom cylinder of Hitachi ZX330-series excavators. Cross-verified sources: eBay lists “Boom Cylinder Seal Kit YA00006596 For Hitachi ZX330-3 ZX350-5”; FASeals lists “YA00006596 Boom Cylinder Seal Kit for Hitachi ZX330-3”; Alibaba lists “Excavator Boom Cylinder Seal Kit YA00006596 for ZX330-3 ZX330-5A ZX330-5G ZX360-3”. The John Deere cross-reference 4S00783 is a Deere seal kit number (shop.deere.com), mapped by AVS.Parts to the 350GLC / 380GLC — which supports the John Deere 350GLC application on this page. Confirm the model and the cylinder of your machine before purchase.

Replacement Scope

One boom-cylinder seal set per kit — rod and piston sealing elements with wipers and wear guidance components as supplied. The kit is referenced for the boom cylinder by all independent sources found (eBay, FASeals, Alibaba); one seller groups YA00006596 with YA00006597 as an arm/boom/bucket kit for the same machines, so confirm the cylinder position on your machine before ordering. No independent source publishes dimensions for this kit; do not assume rod or bore sizes.

Fitment Verification

Models verified across independent sources: Hitachi ZX330-3 (eBay, FASeals, Alibaba), ZX330-5A (eBay, Alibaba), ZX330-5G (Alibaba), ZX350-5 (eBay, oilsealkits) and ZX360-3 (Alibaba, oilsealkits). John Deere 350GLC is supported through the verified 4S00783 cross-reference (AVS.Parts maps 4S00783 to the 350GLC / 380GLC; shop.deere.com lists FYA00006596 as its original). CONFLICT / UNVERIFIED NOTES: the page lists 4649049 as an alternative part number, but 4649049 was not found in any independent source — treat as unverified; one seller (oilsealkits) groups YA00006596/YA00006597 as an “Arm Boom Bucket” kit, but all other sources reference the boom cylinder. Verify your machine model, cylinder position and part number before ordering.
