When it comes to final drive motors, gear oil is the quiet workhorse that makes everything else possible. It cushions the gears, keeps heat under control, and prevents metal-on-metal destruction. But here’s the catch: when gear oil is neglected or handled the wrong way, it can turn into the very thing that shortens the life of your machine.

One of the most frustrating things about equipment failures is how often they sneak up on you. Your machine might sound fine, run fine, and get the job done—until one day, the final drive gives out without much warning. A common culprit? Gear oil that’s quietly been working against you instead of for you. Gear oil is supposed to lubricate, protect, and keep things cool inside the drive. But once it’s contaminated, it stops doing its job, and the damage starts piling up long before you notice anything’s wrong.
In this Shop Talk Blog post, we talk about gear oil contamination, signs to look for, prevention and maintenance tips, and what to do when the damage is done.

You’re on the job, deadlines are already tight, and suddenly your skid steer doesn’t sound or feel right. Every hour of downtime costs not just time but money.
That’s why we’ve put together this Shop Talk Blog post to help you learn the early warning signs of a final drive that’s about to fail. That way, you can catch these problems before they become catastrophic-- and more expensive.
Loss of Power
If your machine suddenly feels weak, maybe struggling to climb like it used to, or is sluggish when it has to move with a load, then here are some possibilities as to what is wrong with it:
- A blocked case drain filter
- Internal wear in the final drive
- Weak charge pump
- Final drive brakes are not releasing
- Other hydraulic issues
If power loss is only on one side, or the machine tries to curve to the side, that’s a big clue it’s a final drive issue.
In the world of compact equipment, even the most seemingly minor component can make or break your machine’s performance. One such part, frequently overlooked but absolutely essential, is the case drain filter. It is a low-profile workhorse hidden in your hydraulic system, and when neglected, it can lead to catastrophic damage to your final drive motor.
At Â鶹ֱ²¥ Final Drive, we’ve seen the aftermath of ignored or clogged case drain filters: cracked housings, shredded rotator groups, and thousands of dollars in repairs. Here’s what every equipment owner and operator needs to know about this vital component.

Replacing your final drive motor is a high-stakes decision affecting your equipment, schedule, and bottom line. But with the correct information and supplier, you can get the job done right the first time. You can't afford to make the wrong decision when it comes to replacing your travel drives.
Gear oil is easy to overlook—until something goes wrong. A noisy final drive, worn planetary gears, or sudden power loss can all point to a single cause: lubricant failure.
Many don’t realize that gear oils are engineered fluids, not just oil. They’re packed with chemical additives that do far more than reduce friction—they help your equipment run cooler, cleaner, and longer. These additives reduce wear, prevent corrosion, fight sludge, and help the oil survive extreme pressure and temperature. Without them, even top-tier base oil won’t cut it.
This Shop Talk Blog post covers what gear oil additives do, how they work, and why they're essential for protecting your final drive motor gearbox. And whether you operate compact track loaders or full-sized excavators, knowing what’s in your oil helps extend service life and avoid costly repairs.
