The Bobcat S650 and Bobcat T650 are far and wide. One is Bobcat’s vertical-lift skid steer. The opposite is the observe loader constructed at the similar platform. Hundreds of them are running these days, and maximum will installed a decade or extra prior to the overall drives want consideration.
When that day comes, here is what you want to understand.

Every facet of the system has its personal hydraulic ultimate force motor. Some are single-speed. Some are two-speed. That one element issues greater than you would be expecting. It adjustments how the system behaves when one thing is going mistaken, and it comes to a decision which alternative unit suits. If you do not know which you’ve gotten, in finding out prior to you order anything else.
Right here at Texas Ultimate Force, we troubleshoot, restore, and remanufacture ultimate drives from a wide variety of machines. The S-series does not fail in unique techniques. The disasters we see hint again to the similar 3 issues that take out Bobcat drives far and wide.
A clogged case drain filter out. That is the massive one. The case drain line is meant to be a low-pressure go back. When the filter out clogs, stress builds the place it should not. Seals fail. Hydraulic fluid and tool oil combine. Within the worst instances, the quilt plate cracks or worse. The repair prices virtually not anything — change the case drain filter out each time you change the opposite hydraulic filters. Many of the drives we see fail this manner by no means had to.

Tools oil overlook. Take a look at the tools oil about as soon as a month or each 100 hours, whichever comes first. Exchange it once or more a 12 months. If the oil comes out with glitter in it, prevent. That is steel, and it approach one thing inside of is already coming aside.
Leaks that get left out. Skinny, fast-leaking fluid issues to the hydraulic facet. Thicker fluid across the sprocket is generally tools oil from a worn face seal. Neither one fixes itself. If fluid can get out, dust can get in, and mud kills drives.
When a system is available in vulnerable, the primary query is inconspicuous: one facet or each?
One facet vulnerable issues at that facet’s circuit — the force, its brake, its two-speed valve, or its pump segment. Either side vulnerable issues on the shared stuff first: fee stress, hydraulic fluid, filters. Two ultimate drives infrequently fail on the similar time. If yours did, search for the typical purpose prior to you search for two new motors.

When a force is finished, you’ve gotten choices. A brand new aftermarket unit. A remanufactured unit. OEM from the broker. Every has trade-offs in price, lead time, and guaranty, and we have coated them intimately in other places in this weblog.
3 issues particular to those machines:
Know your pace. A single-speed unit and a two-speed unit aren’t interchangeable. Verify what is for your system prior to you store.
Your core has worth. A useless force continues to be price one thing as a reman core. Do not scrap it and do not let it disappear. Ask about core credit score whilst you get a quote.
Ask about pairs. Some Bobcat drives are serviced in pairs relatively than one after the other. Ask your provider about their coverage for your style prior to you devote, so the quote you get is the quantity you pay.
The S650 and T650 ultimate drives are stout. We see disasters from skipped upkeep way over vulnerable portions. Change the case drain filter out with the opposite filters. Take a look at the tools oil per 30 days. Care for leaks the week you in finding them. Do this, and the percentages are just right you’ll be able to by no means want the remainder of this text.
If you are already previous that time — one facet vulnerable, noise from the hub, glitter within the oil — name us prior to you order anything else. A 10-minute dialog can prevent from changing the mistaken section.
