265B Final Drive for Excavator spare parts MAG170‑3600 Axial Piston Motor Aftermarket

Product Overview

The MAG170‑3600 is a recognised name in travel motor circles — a heavy‑duty axial piston unit paired with a compact planetary box, specified on the 265B excavator for the kind of steady, low‑speed pulling work that tracks exist for. It sits out of sight inside each track frame, and most operators never think about it until the afternoon one track starts lagging on the haul road. By the time that happens, the piston group has usually been scoring itself for weeks: a faint warmth through the housing, a new hum under reversing load, the way the machine drifts a shade off line on a grade. Ignored, the swarf that comes loose then contaminates the whole travel loop. This aftermarket unit reproduces the MAG170‑3600 as a sealed, bench‑run assembly, so the failed drive can be lifted out whole and the replacement dropped straight in without hunting for loose internal parts.

Core Advantages

1. A known, proven motor platform
The MAG170 family has run on a wide range of 20‑ton class machines for years. Operators and workshops already understand its behaviour, so fitting and diagnosis feel familiar rather than experimental.

2. Torque where it matters on ruts and grades
Hardened gear stages multiply the motor's output down to sprocket speed, so the track pulls steadily through soft spots and uphill trundles instead of spinning or bogging.

3. Fresh sealing keeps contamination out
Every shaft and housing joint gets new lip seals before assembly. On a machine worked through mud and standing water, that seal integrity is what decides whether the drive reaches its first overhaul.

4. One unit, one lift, one job
Motor and reducer arrive bolted together and test‑run, so the fitter does not have to mate components mid‑repair. Less time under the raised track frame means the machine is back earning sooner.

5. Aftermarket build price for an older platform
An exchange drive from the original dealer carries a premium that is hard to justify on a 265B past its early years. This unit restores full track mobility at a fraction of that cost.

Manufacturing & Quality Control

Machined parts are sourced to print and checked on arrival; gear teeth are finish‑ground and case‑hardened to spec. Assembly happens under clean conditions, and each finished drive spends time on a hydraulic test stand where leakage, torque output and noise are recorded. Anything off spec is stripped and reworked. Completed units are plugged, oil‑fogged and crated on dunnage for long‑distance shipping.

Frequently Asked Questions

Q1: How do I confirm the MAG170‑3600 matches my 265B?
A: Read the tag on your existing drive and send the machine serial number. We cross‑check before dispatch — minor build changes do occur across production runs.

Q2: Does this include the sprocket?
A: The listing is the motor and reduction assembly. The sprocket itself usually transfers over from the old drive; let us know if you need a new one as well.

Q3: What should I watch after fitting?
A: Check oil level in the travel circuit, bleed air from the motor, and take the first day easy on grades. Any unusual noise or heat after the first shift should be flagged immediately.

Q4: What's not covered?
A: Defects in materials and build are. Damage from dirty oil, debris sucked into the motor, a stalled track being forced, or a botched install is not. Keep packaging and photos for any arrival claim.
