Product Overview

The 71445785 hydraulic cylinder seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Fiat-Hitachi part number 71445785 (aftermarket cross FH-71445785, Hercules catalog code M-PK-N-N-10-115MM). Independent seal catalogs identify it as a 115 mm piston kit used on the arm cylinder of the Fiat-Hitachi FH130-3 excavator, with additional listings covering the boom and bucket cylinders of the FH150-3.

DJF Seals produces this kit in-house and supplies it at factory-direct wholesale pricing for heavy equipment parts distributors, repair shops and fleet maintenance programs servicing Fiat-Hitachi excavators.

Verified Application

The following application data was cross-checked against industrial seal catalogs, parts resellers and marketplace listings:

Note: specific material grades, pressure rating, temperature range, exact piece counts, certifications and service life are factory data and are not independently verified. Confirm these details with the factory before ordering.

Replacement Scope

This kit covers the sealing elements required for a cylinder rebuild in the 115 mm piston configuration, including the piston sealing elements, rod sealing elements, wiper, wear bands and O-rings supplied in the FH-71445785 configuration. O-RingsAndMore describes the kit as a 115 mm piston kit that includes four wear bands and O-ring seals. Exact kit contents and piece counts should be confirmed with the factory against your cylinder before ordering.

Fitment Verification

The part number, cylinder position and fitments were verified through multiple independent sources:

• Hercules Sealing Products catalog (FH-71445785, M-PK-N-N-10-115MM): Fiat-Hitachi / Fiat Allis kits; Hercules Canada lists FH-71445785 with 115.000 mm bore for model FH130-3, application Arm.
• eBay (Hercules brand): “71445785 Arm Cylinder Seal Kit Fits Fiat-Hitachi FH130-FH150-3” — FH130-3 ARM, 115 mm piston kit.
• O-RingsAndMore: “71445785 Arm, Boom & Bucket Cylinder Seal Kit fits Fiat Hitachi FH130-3 FH150-3” — FH130-3 Arm Cylinder, FH150-3 Boom Cylinder, FH150-3 Bucket Cylinder, 115 mm piston kit.
• excavators-parts.com: “Seal kit for HITACHI X135W EX165W FH130W.3 FH150W 71445785” — confirms the wheeled model fitments.
• WQC Parts: Fiat-Hitachi 71445785 Seal Kit, reference brand/application “Arm”, catalog source 2026 US Mobile Kit Catalog.
• Conflict note: Winschen (page now offline) listed FH300-1 and FH300-2 in the fitment; no other independent source confirms the FH300 fitment, so it is not claimed on this page.
• Conflict note: excavators-parts.com writes the wheeled model as “X135W” while the current page writes “EX135W”; both refer to the same Fiat-Hitachi wheeled excavator family — confirm against your machine’s serial number and parts book before ordering.
• Cross-reference observation: the number 71445785 also appears in the MyCNH store as a New Holland Agriculture “KIT, SEALS” with no listed fitments; this is a group/legacy reference and was not used for the fitments above.
• Materials, pressure, temperature, piece counts, certifications and service life are not independently verified.
