Hydraulic contamination is a major source of problems for any type of hydraulic system, but especially for hydraulic motors and final drives -- which means that it is very important to be well informed on the subject. In this Shop Talk Blog post, we are going to talk about the types and sources of contamination, as well as how to avoid contamination. This information is important for all types of hydraulic construction equipment, from a Terex CTL to a Bobcat skid steer.

Floating Face Seals and Track Drive Maintenance

The floating face seal is a vital part of your travel motor or final drive, whether its on a John Deere skid steer or an ASV compact track loader. It rests against the hub, holding in the gear oil on the planetary side and preventing contaminants from getting in where they can damage bearings and gear. If this seal begins to leak, your travel drive motor will suffer damage. In this Shop Talk Blog post, we are going to talk about 5 things you should know about floating face seals and track drive maintenance.

Love for Machinery

No technician with any love for machinery wants to open up a final drive for evaluation and find it caked in dried mud, debris, and rust. In this article, we are going to go over our procedure for cleaning a final drive before its disassembly.

The final drives that we receive for evaluation, repair, or re-manufacturing are definitely not in like-new condition. In fact, most of them look like this Rexroth final drive from a Bobcat T140/T180/T190.
