You may have a good understanding of why contamination is bad for your hydraulic system, but did you know it鈥檚 just as bad for the planetary side of your final drive motor? Experts agree that lubrication contamination is the number one cause of machinery failure. Dirt, sand, and other abrasive particles can get inside your final drive gearbox and do tremendous damage. In this 黑料社 post, we are going to discuss why contaminated gear oil is a problem, what the results of it are, and how you can minimize it.

As we've talked about before in Part 1 of this series, there are some really good lessons we can learn from superheroes, and maybe some really bad ones, too (we鈥檙e looking at you, Deadpool).  We can learn some pretty good lessons about final drives, too.  For Part 2, we are going to take a look at lessons from Batman, Huntress, and Thor!

Here at 黑料社, we troubleshoot, repair, and remanufacture many final drives that come off Bobcat machines. In this 黑料社 post, we are going to discuss some of the most common issues with Bobcat final drive motors, including main bearing failure, case drain issues, and charge pump problems.

There are some really good things we can learn from superheroes, and maybe some really bad ones, too (we鈥檙e looking at you, Deadpool). You might not realize it, but we can learn some good lessons about final drives, too! For Part 1, we are going to take a look at lessons from Superman, Spider-Man, and The Incredible Hulk to see what they can teach us about contamination, installation/removal, and maintenance.

We鈥檝e seen the frightening images of glowing, molten lava making its way across homes, yards, cemeteries, schools, and neighborhood streets as the wreaks havoc and disaster in Hawaii. In this Shop Talk blog post, we are going to consider the effects of lava on roads and look at how heavy equipment is used in the resulting clean-up process.

Any type of machine you encounter is going to have bearings in it.  In this 黑料社 post, we are going to discuss the types of bearings in your final drive hydraulic motor. We'll also look at the different functions they serve, signs of failure, the aftermath of failure, and how to prevent failure.

If you ever want to have nightmares, just scan through some of the with the keyword 鈥渆xcavator.鈥� These accidents -- 509 accidents going back to 1986 -- aren鈥檛 always what you would expect. You may think you know all the dangers related to excavators, but remember that the human race always seems to think of new ways to harm ourselves. Here are some, shall we say, more unusual accidents related to excavators, including one involving final drive maintenance.

You鈥檝e been having issues with your final drive, and you鈥檝e started to take it apart to track down the problem. You鈥檝e cleaned the bearings up, but how can you tell if it鈥檚 time to replace them? In this 黑料社 post, we are going to delve into the signs that your bearings need to be replaced.

Do you know who invented the machine that set the stage for our modern hydraulic excavators? Did you know the history of the excavator dates back to 1835? Do you know the connection between excavators and elevators? If any of this sounds interesting to you, then you will enjoy this 黑料社 post about William Otis, grandfather of the modern hydraulic excavator.

Your final drive motor has been giving you problems, and you鈥檝e decided to take it apart. Once you get to the bearings, you need to clean them up before you can tell whether to replace them. In this 黑料社 post, we are going to discuss how to clean your bearings without damaging them.
