MAG-85-2400 final drive for Case CX160 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 CASE CX160 is a 16‑ton excavator built for general construction, pipeline work and site prep — a machine that balances digging power with a size that lets it move between jobsites on a standard trailer. The axial piston motor and planetary reducer under each track, carrying drive model MAG‑85‑2400, is what gives it that mobility: turning hydraulic flow into the slow, torque‑rich rotation pulling the machine across uneven ground. On a mid‑size CASE worked hard, drive wear shows up gradually. One track lags the other, the machine drifts on level ground, the drive housing runs warmer than it should after a run, and a note from the track motor gradually deepens. By the time a track hesitates under load, the piston group and reduction gears are already scoring against each other. This aftermarket drive reproduces the original MAG‑85‑2400 motor‑and‑reducer pairing as one sealed, tested unit, so the worn assembly comes off and the new one bolts straight back on.
Core Advantages
1. Torque output matched to a 16‑ton pipeline machine
The CX160 meets real resistance on slopes and broken trench ground. Hardened gears and piston surfaces hold the sprocket torque the tracks need to push and climb, without the laboured travel that undersized replacements produce.
2. Sealed for the mud and water of trenching work
Pipeline and utility sites expose the drive to mud, standing water and fine silt. Fitted output‑shaft and housing seals keep that contamination out of the motor and gearbox — the single most important factor in drive longevity.
3. Quiet, even gear meshing that protects the reducer
Precision‑cut planetary gears with controlled backlash run smoothly — no clicking, no grinding note. Even load sharing means the gears wear slowly rather than hammering one another into early failure.
4. A complete matched assembly for fast turnaround
Supplied as one motor‑and‑gearbox unit, the final drive bolts straight into the original mounting position. No mixing separate parts, no mid‑job mismatches — important when a machine that earns by the hour is sitting still.
5. Aftermarket value for a working CASE fleet
An original CASE final drive exchange carries a serious price tag. This aftermarket unit delivers dependable output at a fraction of the cost, with sample and batch supply for workshops maintaining several CX160 machines.
Manufacturing & Quality Control
Each drive is assembled under controlled conditions: precision machining of gear and housing parts, heat treatment of wear surfaces and clean build. Every unit is bench‑tested for output torque, leakage and running noise before release, and only passing assemblies are packed. Anti‑rust preservation and shock‑absorbing export packing protect the unit during long‑distance transport.
Frequently Asked Questions
Q1: How do I confirm MAG‑85‑2400 matches my CX160?
A: Compare the drive model on your existing final drive and share your machine serial number. CASE build variants can differ, so we verify before dispatch.
Q2: Is this the complete motor and reducer?
A: Yes — it is the full axial piston travel motor and planetary reducer unit, ready to bolt on as one piece. If you need the motor or gearbox separately, please ask and we will confirm availability.
Q3: What faults point to final drive wear?
A: Uneven track speed, pulling to one side on level ground, a hot or noisy track motor and tracks that fail to pull under load. Inspect before contamination spreads through the travel circuit.
Q4: What is the warranty position?
A: Manufacturing and material defects are covered. Damage from contaminated oil, foreign objects in the travel circuit, track obstruction, overload operation or incorrect installation is excluded; please follow the CASE service manual for fitting and bleeding.
