Product Overview

The ZX200‑8 is the modern face of the 20‑ton class — a fuel‑efficient, low‑emission Zaxis that you see on everything from urban sewer jobs to large rural earthworks. Under each track frame sits the hydraulic motor and planetary reducer, covered by references 9170996, 9233687, 9195447 and 9233688, that turns pump flow into the slow, steady pull moving the machine between cut and stockpile.

On a worked ‑8 series Hitachi, the drive wears down in quiet stages. The operator notices the two tracks no longer quite match on a long haul road, that the track shell warms after a shorter trundle than it should, and that a faint whine creeps into the circuit under load. Most crews nurse it another week — but by then the piston block and reduction gears are already shedding swarf into the travel oil. This aftermarket unit reproduces the original motor‑and‑reducer pairing as one sealed, bench‑run assembly, so the worn drive lifts out whole and the new one bolts straight back in.

Core Advantages

1. Four references, one matched drive
The four part numbers cover build variants across the ZX200‑8 run. We confirm the correct unit against your machine serial number, so workshops stocking this drive can support the whole run without guessing.

2. A lapped piston group that holds pressure
The cylinder block, piston shoes and valve plate are finished to close clearance, so oil pressure does not bleed internally. Both tracks pull in step — no drift, no lazy side, no hesitation when the bucket loads up.

3. Hardened gears for truck‑loading cycles
A day on a ZX200‑8 means dozens of reverses, ramp climbs and loaded pulls. Case‑hardened planetary teeth share the load across several surfaces, and controlled backlash keeps the reducer quiet.

4. Sealed for dust season and mud season alike
Whether the site is dusty topsoil or muddy clay, fresh shaft and housing seals keep grit out of the lube. That is the line between a drive that reaches its first rebuild and one that does not.

5. Drop‑in fit, same afternoon
Flange, studs and ports match the original, so the service crew swaps the whole drive rather than assembling it on the floor. A parked 20‑ton machine is a parked earner.

Manufacturing & Quality Control

Parts are machined to Hitachi print, heat‑treated at wear points, and assembled in a clean shop. Each finished drive runs on a hydraulic stand while torque, leakage and noise are logged; units outside spec are reworked before packing. The internals are fogged with preservation oil, ports are plugged, and the assembly ships on shock‑absorbing dunnage.

Frequently Asked Questions

Q1: Which of the four part numbers do I order?
A: Read the tag on your existing drive and match it against 9170996, 9233687, 9195447 or 9233688. Send the machine serial number and we confirm the exact variant before dispatch.

Q2: Does this fit the ZX200‑8 rather than the ‑3 or ‑1?
A: The ‑8 series uses a later drive platform than the older ZX200 generations. Sending the serial number removes any doubt — we will not ship a mismatched unit.

Q3: What break‑in does the operator need?
A: Take the first shift easy on loaded grades. Light cycling seats the new gears and seals, then check oil level and fitting torque after the first day.

Q4: Can I get this with a local warranty in my country?
A: Warranty is handled directly through us. Keep the invoice and packaging; if a unit fails in service, we arrange replacement parts or a swap rather than routing you through a dealer network.

Q5: Do you supply the track adjuster or idler at the same time?
A: We focus on the final drive itself, but most undercarriage parts are available on request. Tell us what else the machine needs and we will quote it together to save on freight.
