Fuel Injector for Hitachi ZX210-3 / Case CX210B (Isuzu 4HK1) - Replaces 8982843930 - Genuine OEM

Genuine OEM Fuel Injector for Hitachi & Case Excavators (Isuzu 4HK1)

Restore your excavator's power without paying the dealership ransom. This is a Genuine OEM common rail fuel injector — the exact same injector used in the Isuzu 4HK1 Tier 3 engine found in Hitachi, Case, and Link-Belt excavators. OEM part number 8-98284-393-0 (Hitachi) / 8-97329-703-5 (Case). Brand new, ready to install.

The Problem

Your 20-ton excavator is throwing codes, smoking, or losing power. The dealer wants $3,200+ for a set of 4 injectors. You know the machine needs them — bad fuel, high hours, and contamination kill common rail injectors. Every day it sits is money lost.

The Solution

We supply the exact same Genuine OEM injector for half the dealer price. Same part, same performance, same reliability — just a smarter supply chain. At $425 per injector, a full set of 4 costs $1,700 instead of $3,200+. That's $1,500+ back in your pocket.

Installation Notes

When replacing the 8982843930 injectors:

• Always use the new copper crush washer and O-ring included with each injector
• Torque to factory spec (check your Isuzu 4HK1 service manual)
• Replace fuel filters before installing new injectors — contamination killed the old ones
• Bleed the fuel system after installation
• If replacing all 4, consider replacing the common rail pressure relief valve at the same time (it often fails when injectors go bad)
• Run a forced DPF regen after installation to clear any accumulated soot

Frequently Asked Questions

Is this a genuine OEM injector?
Yes. This is a genuine original-equipment common rail injector, not an aftermarket or Chinese clone. The OEM part number is laser-etched on the connector head. Counterfeit injectors are a serious problem in this market — we only source from verified OEM distributors and authorized diesel specialists.

Will this fit my Hitachi ZX210-3?
Yes. The ZX210-3 uses the Isuzu 4HK1 engine. The injector part number 8-98284-393-0 (8982843930) is used across all Hitachi Zack-3 series excavators with the 4HK1 engine, including the ZX170W-3, ZX200-3, ZX210-3, and ZX240-3.

Should I replace all 4 injectors at once?
We strongly recommend it. When one injector fails due to fuel contamination, the others have been exposed to the same contamination and are on borrowed time. Replacing all 4 eliminates repeat downtime and ensures balanced fuel delivery across all cylinders.

How much can I save vs. the dealer?
Hitachi and Case dealers quote $650–$850+ per injector — that's $2,600–$3,400+ for a full set of 4. We sell the identical Genuine OEM injector for $425 each. A full set of 4 saves you $1,000–$1,800+.

What causes these injectors to fail?
The #1 cause is contaminated fuel — water, dirt, or debris in the fuel system damages the precision internals of the common rail injector. High-hour machines (8,000+ hours) also experience natural wear. Symptoms include rough running, white/black smoke, loss of power, misfire codes, and increased fuel consumption.
