Hitachi HMGF35 9116393 final drive for Hitachi EX200-2 midi excavator
If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

Product Overview
The Hitachi EX200‑2 sits between the original EX200 and the later ‑3 — an early 20‑ton machine that helped define its class, and one that owners still keep working because it is simple to fix and built to last. Under each track sits the HMGF35 axial piston motor and planetary reducer, carrying reference 9116393: the unit that turns hydraulic flow into the slow, powerful rotation pulling the machine across site. On a legacy machine this age, drive wear arrives in small increments rather than all at once. The two tracks stop quite matching, the machine drifts across level ground, the drive housing warms after a longer run, and a note from inside the track frame gradually deepens. Ignore it and a track will eventually hesitate under load — by then the piston group and gears are already scoring. This OEM‑grade drive reproduces the original HMGF35 motor‑and‑reducer pairing as one sealed, tested assembly, so the worn unit comes off and the new one bolts straight back on.
Core Advantage
1. OEM‑grade internal clearances for a machine with built‑up wear
An older excavator's valves and lines carry years of use. A drive finished to OEM tolerances holds its pressure and flow rather than amplifying that wear — the result is stable track pull, not a short‑lived performance spike.
2. Hardened gears built for decades‑proven duty
The HMGF35 planetary set follows a long‑proven Hitachi layout, with case‑hardened teeth that share the drive load evenly. Meshing stays smooth and quiet, and wear from years of track push slows right down.
3. Sealed for quarry dust and standing water
Legacy EX machines work through long hours in the harshest site conditions. Fitted output‑shaft and housing seals keep grit out of the motor and reducer — the protection that decides whether the drive lasts its service life.
4. One tested, matched unit for a clean swap
Motor and reducer arrive pre‑assembled and bench‑checked, so the fitter removes the old drive and bolts on the new one without sourcing separate components. No mid‑job mismatches, no second visit to chase a leak.
5. OEM‑spec quality without the dealer price tag
Renewing the drive to OEM grade restores the EX200‑2's mobility far below the cost of an original exchange unit, with sample and batch supply for workshops keeping these legacy Hitachis on the books.
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 9116393 matches my EX200‑2?
A: Compare the reference on your existing drive and share your machine serial number. Early Hitachi build variants can differ, so we verify before dispatch.
Q2: Is this the complete motor and reducer?
A: Yes — the listing covers the full axial piston motor and planetary reducer as one assembly, ready to bolt on. Separate components can be checked on request.
Q3: What faults point to drive wear?
A: Uneven track speed, drifting on flat ground, a hot or noisy track motor and tracks that hesitate 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.
