Product Overview

The 71408778 seal kit is a factory-manufactured aftermarket replacement kit cross-referenced against the Fiat-Hitachi part number 71408778, also written FH-71408778 by some suppliers. Independent parts suppliers describe 71408778 as the lift cylinder seal kit for the Fiat-Hitachi EX165 excavator: O-RingsAndMore lists “71408778 Lift Cylinder Seal Kit fits Fiat Hitachi EX165” and “Fiat-Hitachi FH-71408778 Lift Cylinder fits EX165”; several eBay listings carry “71408778 Lift Cylinder Seal Kit fits Fiat Hitachi EX165”; and aftermarket suppliers such as RuiJueParts list “EX165 Lift Cylinder Seal Kit HITACHI” for this number. Multi-language Alibaba storefronts describe 71408778 as the lift cylinder seal kit for the Fiat-Hitachi EX165 excavator.

DJF Seals manufactures and supplies the 71408778 kit at factory-direct wholesale pricing for Fiat-Hitachi equipment dealers, independent repair shops and fleet maintenance programs.

Verified Application

The following application data was cross-checked against independent parts suppliers and marketplace listings:

Note: specific rod and bore dimensions, 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

One seal set per kit for the lift cylinder of the Fiat-Hitachi EX165: the rod and piston sealing elements, with wipers and wear-guidance components as applicable to the cylinder. Confirm the machine model and the cylinder you are resealing before ordering, and confirm exact kit contents and piece counts with the factory against your cylinder.

Fitment Verification

The part number, product type, cylinder position and machine model were checked against multiple independent sources. The following points remain open and are preserved here rather than resolved by assumption:

• Lift cylinder position is consistently described across O-RingsAndMore, the eBay listings, RuiJueParts and the Alibaba storefronts.
• Machine model: the Fiat-Hitachi EX165 is a crawler excavator of roughly the 17 tonne class; documentation sources such as LECTURA Specs cover the EX 165 for 1999 to 2002. The EX 165 W and EX 165 WT are separately listed wheeled variants. Confirm the exact variant and serial number of your machine before ordering.
• Do not conflate similar numbers: one supplier catalogue line (RuiJueParts) shows “71408778 71418514 EX165 Lift Cylinder Seal Kit HITACHI”, placing 71418514 alongside 71408778. 71418514 is a different part number and is not asserted here to be interchangeable with 71408778. Verify which number your machine requires.
• Related but different numbers: 71418431 (bucket and stick cylinder, EX215), 71466446 (rocker cylinder, EX165) and 71445742 (lift cylinder, FH200-3) belong to different cylinder positions and machine models and are not interchangeable with 71408778.
• Not asserted for 71408778: rod and bore dimensions, material grades, pressure rating, temperature range, exact piece counts, certifications and service life. None of these are confirmed by an independent source, and supplier marketing wording such as pressure or abrasion resistance is not treated here as verified data.
