ZX180LC‑5G ZX180‑5G Final Drive for Excavator spare parts 9283952 9283953 hydraulic motor reducer OEM

Product Overview

An 18‑ton excavator earns its living by moving — when the ZX180LC‑5G or ZX180‑5G stops tracking, every minute parked is money lost. Under each track frame sits the hydraulic motor and planetary reducer, references 9283952 and 9283953, that converts the pump's high‑flow oil into the slow, twisting force that turns the sprocket. These modern Zaxis machines spend their shifts on road widening, drainage work and urban site prep, where they are constantly reversing, pivoting and pulling across uneven ground. That constant cycle wears the drive down in ways that are easy to miss at first: the two tracks stop quite keeping pace, the machine drifts on flat asphalt, the output shaft housing runs warmer after a shorter trundle than it should, and a low whine from the track motor builds with load. Left until a track slips on a grade, the piston group and reduction gears are already scoring metal through the oil. This OEM‑grade drive is built as one matched motor‑and‑reducer assembly, covering both the LC long‑undercarriage and standard undercarriage versions, so the worn unit lifts out and the new one drops straight back in.

Core Advantages

1. Both undercarriage variants covered by one range
The 9283952 and 9283953 numbers cover the LC and standard undercarriage builds, so workshops running a mix of ZX180‑5G machines can stock from the same range. Send the serial number and we pin down the exact unit.

2. A piston group that holds its pressure lap after lap
The cylinder block, piston shoes and valve plate are machined to close running clearance, so oil pressure does not bleed away inside the motor. The result is even pull from both tracks — no crab‑walking, no lazy side, no hesitation when the bucket crowds the trench wall.

3. Hardened gears that shrug off urban‑site shock loading
Planetary gears with case‑hardened teeth mesh smoothly and share the drive torque across several teeth at once. That is what keeps the drive quiet over years of paving breakers, ramp climbs and repeated track reversal.

4. Sealed against the dust and washwater of city work
Roadwork and urban yards throw up dust, mud and pressure‑washing water. Correct output‑shaft and housing seals keep that grit out of the motor and gear oil — the single biggest factor in whether a modern drive reaches its service hours.

5. A complete tested unit for fast urban turnaround
When an 18‑ton machine blocks a city road or a trench line, the clock is ticking. Motor and reducer arrive pre‑assembled and bench‑checked, so the whole drive swaps in one visit without chasing loose components.

Manufacturing & Quality Control

Production follows OEM‑grade specification: material certificates on incoming steel, precision CNC machining of housings and gears, case hardening of all wear surfaces, and clean‑area assembly. Each finished drive is loaded on a test rig to run output torque, internal leakage and noise checks; units outside the acceptance window are rejected rather than shipped. Completed assemblies get anti‑rust preservation, moisture‑proof sealing and shock‑absorbing export crating, so they reach the workshop ready to bolt on.

Frequently Asked Questions

Q1: How do I tell 9283952 and 9283953 apart?
A: The numbers split across undercarriage builds. Read the tag on your existing drive and send the machine serial number — we match the correct unit before it leaves.

Q2: Do I need to buy the motor and gearbox separately?
A: No. This listing is the complete hydraulic motor with planetary reducer as one bolt‑on assembly. If you need only internal parts, ask and we will confirm what is available.

Q3: What does the fitter need to do after fitting?
A: Torque the mounting bolts to spec, top up the travel oil, bleed air from the motor, and do a slow no‑load track test before digging. Refer to the Hitachi service manual for the bleeding sequence.

Q4: What voids the warranty?
A: Manufacturing and material defects are covered. Damage from dirty oil, debris in the motor, track obstruction, forcing a stalled drive, overload or botched installation is not. Photograph any arrival damage before uncrating.
