ZX60 Final Drive for Hitachi Excavator spare parts 4678268 hydraulic motor reducer OEM

Product Overview

The Hitachi ZX60 sits at the upper end of the compact excavator class — a 6‑ton machine with enough reach and dig depth for real earthmoving, yet small enough to work on residential lots, road trenches and confined urban sites. The hydraulic motor and planetary reducer under each track, referenced by part number 4678268, is what moves it: turning hydraulic flow into the low‑speed, high‑torque rotation that pulls the machine across every kind of ground. On a compact machine that spends its day reversing, pivoting and climbing in and out of trenches, wear in the drive adds up quietly. One track begins to lag, the machine drifts on level ground, the drive housing warms faster than its opposite side, and a note develops inside the track frame that was not there last month. Running on past that point only scores the piston group and gears further. This OEM‑grade drive is built as one matched motor‑and‑reducer assembly, so the worn unit can come off and the new one bolt straight back on.

Core Advantages

1. Motor internals that hold pressure for even track pull
The piston, cylinder block and valve plate are finished to tight tolerances, so hydraulic pressure does not leak away inside the motor. Both tracks then push in step — no drifting, no slow side, no hesitation when the bucket digs into a hard cut.

2. Reduction gears built for trench‑and‑pivot duty
A ZX60 reverses and repositiones hundreds of times a day. Hardened planetary gears with controlled backlash absorb that daily load smoothly and quietly, without the click or grind that signals the teeth are hammering themselves.

3. Sealed against the wet, dusty reality of compact sites
Compact drives sit close to the ground, taking mud, water and fine trench dust all shift. Fitted shaft and housing seals keep that contamination out of the motor and gear oil — the protection that decides drive longevity.

4. One tested assembly for a clean, fast fit
Motor and reducer arrive pre‑assembled and bench‑checked, so the whole drive swaps in one operation. No sourcing separate parts, no mid‑job mismatches — the machine is back on track quickly.

5. OEM‑spec quality at a practical repair cost
Renewing the drive to OEM grade restores the ZX60's mobility far below the price of a dealer exchange unit, with sample and batch supply for workshops maintaining compact Hitachi machines.

Manufacturing & Quality Control

The OEM‑grade route follows controlled specifications: material certification, precision machining of housings and gears, case hardening of wear surfaces and clean assembly. Each completed drive runs on a test rig to verify output torque, internal leakage and running noise before release, and only passing units are packed. Full preservation coating, moisture sealing and shock‑absorbing export casing protect the assembly during transport.

Frequently Asked Questions

Q1: How do I confirm 4678268 matches my ZX60?
A: Compare the reference on your existing drive and share your machine serial number. Compact Hitachi variants can differ, so we verify before dispatch.

Q2: Is this the complete motor and reducer?
A: Yes — the listing covers the full hydraulic motor with planetary reducer as one assembly, ready to bolt on. Separate components can be checked on request.

Q3: What faults point to drive wear?
A: Mismatched track speeds, drifting on flat ground, a warm or noisy track motor and hesitation under load. Inspect early, before debris spreads through the travel circuit.

Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage from contaminated oil, debris in the motor, track obstruction, overload or incorrect installation is excluded; follow the Hitachi service manual for fitting and bleeding.
