The most modern hydraulic motor designs include clearances that are much smaller than those of older models. These smaller clearances, while providing even better efficiency and performance, can cause their own share of problems. That’s the topic of this Shop Talk Blog -- as well as how to deal with the problems that result from reduced clearances.

In our continuing discussion on some of the worst final drive motors fails we’ve seen here at Texas Final Drive, allow us to present a very badly scarred radial piston hydraulic motor. This final drive was totaled -- there is just no coming back from this kind of damage.

In past blog posts, we’ve talked about when to flush your hydraulic system. As you probably know, there is a major difference between flushing a hydraulic system (which involves a great deal of time, quite a bit of hydraulic fluid, and multiple filter changes) and merely changing out the fluid. Still, it seems, there is some confusion about when to change out your hydraulic fluid, and manufacturer guidelines can be a bit misleading.

The effects of cavitation are usually pretty easy to identify -- it causes a metal surface to have a pitted, crater-like appearance. What happens when cavitation takes place, and how it actually causes damage to normally resistant metals, isn’t quite as well known. In this Shop Talk Blog post, we’ll be talking about what causes cavitation and why it can result in so much damage.

When you’re out in the field running drilling equipment, you can’t afford to have your hydraulic system break down. The best way to prevent a breakdown is preventative maintenance, and that includes your final drive motors, too. In this Shop Talk Blog post, we are going to talk about maintaining the hydraulic propel motors on your drilling equipment.

Here at Texas Final Drive, we work quite a bit with radial piston hydraulic motors and Geroler motors. These motors, like anything else mechanical, will eventually wear out. The most damaging wear affects the cam ring, and that’s the topic for this Shop Talk Blog post.

We see quite a few final drive hydraulic motors that have been severely damaged by abrasive contamination on the hydraulic side. In this Shop Talk Blog post, we discuss what abrasive contamination is, where it comes from, what it does to your final drive, and how it can be minimized.

Your final drive is just one of many components that make up the hydraulic system on your machine. All those components share the same hydraulic fluid. If contamination enters at one point in the system, you run the risk of it causing damage to other parts of the system. That’s why it is so critical to you do your best to prevent hydraulic contamination. In an ideal world, you would only open up the hydraulic system in a clean environment -- but we realize that isn’t always realistic. Here are some practical hints and tips to help you prevent hydraulic contamination.

Hydraulic fluid is the lifeblood of a hydraulic system, whether that hydraulic system is on a full-size excavator or a small skid steer loader. In this Shop Talk Blog post, we are going to discuss all things hydraulic -- hydraulic fluid, hydraulic contamination, hydraulic flushing, and hydraulic injection.

Hydraulic filters help to remove contaminants from your hydraulic fluid as it flows through the system. Many of these particles are so tiny they aren’t visible to the naked eye. But, that doesn’t mean they can’t wreak havoc on your hydraulic system, as well as your final drive motors. In this Shop Talk Blog post, our focus will be on reviewing the basics of hydraulic filters.
