2002 Bobcat 863 Oil Cooler

[Chrislrod863]

Hello Fellow skid steer owners. This is my first time on this site, and my first time owning a skid steer. I’m about to do all the routine maintenance, and oil changes on my bobcat. I wanna know how I can drain the oil from the cooler to replace all oils and freshen up all oil in my system?Another question is how many quarts of oil does the bobcat take.

Hi and welcome to the forum!
When changing the hydraulic oil, it is very difficult to get every last drop of oil out of the system, and for the most part nobody bothers, unless you have had a catastrophic failure of a pump or a motor. Not only will there be some oil in your cooler, the cylinders and hydrostatic drive will also have some in them too.
What some people do is connect a hose to one of the aux. ports and run the machine at idle while actuating the aux. control, allowing the machine to pump itself out into a bucket. When the flow begins to spit air, shut the machine off and refill with fresh fluid.
More importantly, change the hydraulic filter.
With respect to how much fluid your system holds, somebody else will have to chime in on that. I know our 773 takes nearly a whole 5 gallon / 20 liter pail to refill it. I am thinking yours is probably near the same.
Hope this helps - SR

Thanks for the info. I was wondering about the oil cooling system that’s on top of the motor. I read a lot about oil changes and oil turning black right away because of the oil in the cooling system. Is there a way to drain the oil from the radiator that is oil cooled? Thanks in advance.

I second that: welcome to the forum! The 863 uses the Deutz engine which is oil cooled. There are two oil coolers ("radiators") above the engine. The top one cools the hydraulic oil, and the lower cools the engine oil. I believe most if not all of the engine oil drains back into the oil pan when the engine's off. I just drain the engine oil pan, then refill with about 11 qts of oil. --- SkidRoe described changing the hyd oil. There are differing opinions about how to drain it. I drain the chain case oil first, then rig up a hyd hose to the aux hyd connector (lower I believe) then turn on the hyd oil to the aux connector, with the other end of the hose stuffed in the chain case fill port. When it's essentially out of hyd oil, the line will start to sputter, and I turn off the aux hyd pump at that point. That puts several gallons of fairly good oil into the chain case at no cost. I will point out that our guru Tazza takes the top chain case cover off and mops out the bottom of the chain case. ---Bobbie-G

my first time here have run skid steers for 40 years but owning and maintaining them I'm a semi rookie just sold a case 1840uniloader I am bobcat and like th foot action I hear my 863 can be foot or hand controlled and no water coolant system only oil cooled? I also recently got an antique skid steer a raider RAIDER mfg by mill corp in Minnesota they are no longer in service hoping parts will be not too hard to find has 17 hp Kubota
