When a final drive starts acting up, the instinct is to jump straight to "I need a new one." Sometimes that's true. Often it isn't. A weak charge pump, a clogged case drain filter, tracks set too tight, or a machine stuck in high-speed mode can all mimic final drive failure perfectly. And if you replace the drive without finding the real cause, you'll be back in the same spot in a few hundred hours, except now you're out the cost of a motor too.

This guide pulls together everything we've learned diagnosing final drives at Texas Final Drive. From the questions to ask before you even open a toolbox, to symptom-by-symptom troubleshooting, to the tests our techs actually run in the shop, you can find information here. Whether you're running a single skid steer or managing a fleet, the goal is the same: figure out what's really wrong before you spend a dollar fixing it.

You’re wrapping up a long day when you notice something small, like sluggish travel speed, uneven tracks, or a dark spot under your machine. It’s easy to ignore, right? And doesn’t seem to be a big deal. It can wait a few days. But far too often, a few days turn into weeks and months, and minor issues turn into significant problems fast. And keep this in mind: Every minute of downtime, every drop of leaking fluid, and every bit of neglect quietly eats into your bottom line.

In this Shop Talk Blog post, we’re going to look at five ways your mini excavator might be draining your wallet and what you can do about it.

Ignoring Track Tension

If you don’t keep the tracks on your compact excavator at the proper tension, there’s going to be some problems. If you keep them too tight, you’re going to see excessive wear on critical components like the sprockets and rollers -- and your final drive motors. On the other hand, if the tracks aren’t kept tight enough, the tracks are more likely to slip and risk derailing in the middle of a job. 

Have you ever had a skid steer or excavator break down in the middle of a big job?

In this Shop Talk Blog, we’re going to discuss how reliability is built, not something to take for granted. It starts with good habits, regular checks, and a strong maintenance culture.

What is a final drive motor?

A final drive motor is a hydraulic motor that converts hydraulic pressure into mechanical torque. It drives the tracks or wheels of both heavy and compact equipment like excavators, compact track loaders, and skid steer loaders. A final drive motor combines a hydraulic motor with a gear reduction system to provide the necessary force for movement.

As an owner or operator of compact and heavy equipment, you play a crucial role in maintaining your final drive motor. Your efforts in this area improve your equipment's performance and help avoid costly repairs and downtime. 

We know how essential maintenance is to your equipment's performance and value, so here’s a guide to final drive motor maintenance. This Shop Talk Blog post focuses on industry best practices to keep your motors in top shape.

We know that it’s vital to keep your skid steers rolling year-round and that the key to their reliability and performance lies in maintenance.
