Think final drive motors don鈥檛 need maintenance? Think again! While they鈥檙e built to last, ignoring routine care can lead to big problems down the road鈥攍ike leaks, breakdowns, or even total failure. The good news? A little maintenance goes a long way in keeping your equipment running smoothly, saving you time and money.
In this post, we鈥檙e busting common myths about final drive motors and sharing simple tips to keep them in top shape. Let鈥檚 dive in and set the record straight!

Reality: While final drive motors are durable, they must be regularly maintained. Maintenance includes:
Besides the obvious benefits of maintenance, it also ensures the life of your final drive, enhances efficiency, and helps promote excellent performance. If you don鈥檛 want to be stranded with a compact machine that won鈥檛 move or have to pay costly repair or replacement costs for your final drive, maintain your final drive motors. Neglecting maintenance can lead to decreased machine performance, increased fuel consumption, and even total machine failure.
Reality: Leaks don鈥檛 always signal that a final drive motor needs replacement. Often, the issue is due to worn seals, overfilled fluid, or other repairable problems. Taking the time to diagnose the source ASAP cause can save unnecessary repair expenses.
Some people think leaks are just part of owning equipment, but hydraulic fluid and gear oil leaks can be highly problematic for your final drive motors. Keep an eye out for leaks, such as puddles of oil under the machine or visible oil on the motor housing, and keep in mind that the more fluid there is, the more likely it is that the leak is on the hydraulic side of your final drive. Most leaks are as simple as replacing a seal or gasket.
Reality: Contamination is one of the leading causes of hydraulic motor failure. Dirt, water, or metal particles in the hydraulic fluid can damage components, reduce efficiency, and shorten the motor鈥檚 lifespan. Proper filtration and regular fluid changes are crucial.
In fact, we can鈥檛 emphasize this enough. If either the hydraulic fluid or gear oil in your drive motor ends up contaminated, it will create worse problems. Contamination issues either lead to further problems (e.g., air in the fluid and cavitation) or generate more contamination (e.g., more metal slivers and particles because abrasive contaminants are present).
Another source of problems with contamination is the case drain filter that is prevalent in Bobcat machines. The case drain is a low-pressure line from your final drive motor to the hydraulic reservoir. When that filter gets clogged, pressures will build up to the point that your final drive motor ends up totaled. Replace the case drain filter when you replace the other hydraulic filters on your machine.
Reality: Just because the motor seems to be working fine doesn鈥檛 mean there aren鈥檛 underlying issues. can help catch problems like wear, leaks, or contamination early, preventing costly downtime and breakdowns. Basically, if you wait until something breaks to inspect it, it is way too late.
Check for signs of leaks, regularly check the gear oil levels, and notice any changes in your final drives鈥� performance. Just because it works today doesn鈥檛 mean it will work tomorrow.
