My stealership is very far away, therefore, I prefer to order my fluids and filters online. However, there is a pretty tight lid on the cross reference in fluids and filters. The Amsoil site has a good start to the fluid cross reference. I bet it would be advantageous for the Brutus and 3650 owners to be able to cross reference the Fluids and Fliters to different brands.

Bobcat dealer-installed Donaldson P821575 air filter

I cannot find much on the Air Filter:
Bobcat Part numbers are - 7025283, 7027718
My Bobcat 3650 has a Donaldson RadialSeal™ P821575 air filter. Dimensions are slightly different from Fleetguard air filter AF25551, and the price is a little lower.

I did a bit of research on the hydraulic fluid and it appears that Mobile DTE 10 Excel 46 ought to work. It replaces Mobile DTE 15m, which I cross referenced to via looking up the MSDS from Polaris' hydraulic fluid (http://polaris.hs.llnwd.net/o40/common/pga/pdf/sds/11250_Brutus-Hydraulic-Fluid_05272015.pdf).

Unfortunately the MSDS for Mobile DTE 10 Excel 46 doesn't list the "ingredients" as does the MSDS for the Mobile DTE 15m. Pretty sure that when manufacturers bring out something new as a replacement that its backward compatible (this might be like the difference between UDT and Super UDT). Here's the specs on the Moble DTE 10 Excel 46:

Mobil DTE 10 Excel? Series

IF you can find this cheaper than what Polaris sells theirs for (in this case it looks like the price on Polaris' fluid is cheaper), perhaps from a local Mobil distributor, then it should be viable.

If someone's got a jug of the Polaris fluid around could you check to see if it's got any ISO numbers on it?

substitute for Polaris/Bobcat fuel/water separator (fuel filter)?

I cannot find much on the Fuel Filter either:
Bobcat - 6988961
I see several websites list the Donaldson P551099 as a direct replacement for the Polaris/Bobcat fuel filter? Looks identical.

I'm tempted to plumb a dedicated water separator in before the fuel filter, one of the small ones with a clear chamber, petcock, and barb to retain a drain hose.

I've been trying to get regular maintenance done on my Brutus. Got everything except the hydraulic fluid. Ordered everything through the local Polaris dealer only to be informed after nearly a month that Polaris won't ship them (and I'd already paid for it) the hydraulic fluid! Talking to one of the parts guys at the dealer I'd told him that if Polaris wasn't going to make it available then they better inform their customers what alternatives can be used. This guy, parts guy, was really good about beating on Polaris (other folks didn't put any real effort into it), he says that he was told that "SAE J300" is the equivalent.

I've popped up a few products that are spec'd "SAE J300" and I'm a bit baffled as they all seem to be more engine-biased than pump-biased. Anyone have any insights here?

Scary part is that Polaris could have just BS'd the parts guy knowing that there's almost no way they could be held liable for any damages that could be incurred.

Based on this episode I can state that I'll never buy a product from Polaris again.

Bobcat fluids

Bobcat lists these part numbers:
Hydraulic/Hydrostatic Fluid (1 Gal.)* *6904026
Synthetic Hydraulic Fluid (1 Gal.)* *6988778
Biodegradable Hydraulic Fluid (1 Gal.)* *6988777

The first fluid listed, #6904026, is the same as for their skid steer products.

Kevin, thanks for the reply.

Interestingly, looking up 6904026 I ran across this:

Alternative bobcat hydraulic oil? | Page 2 | Heavy Equipment ForumsAlternative bobcat hydraulic oil? | Page 2 | Heavy Equipment Forums

For what it's worth, I talked to a guy who had an older jug of the Bobcat oil, and he said it had Mobil DTE 15M on the label in small print as well. Mobil DTE 15M Has been replaced by Mobil DTE 10 Excel 46, which is an AW 46 hydraulic oil.
Based on all this I'd have to say that my earlier research appears to have dug up a viable candidate.

Hydraulic fluid in the service manual states:

For conditions +4C - +49C: VG 100, min VI 130
For conditions -40C - +27C: VG 46, min VI 150

The three Bobcat fluids mentioned here already are good for -40 - +120 apparently.

I just picked up a couple gallon bottles on ebay.

Anyone have the information on the filters for the 2016 and later models (new Kohler engine)? I failed to check that on this thread and got in to change the oil and I have the wrong filter. I can't read the model number on the filter that's there now, so just wondering if anyone had already run this down.


Thanks in advance!
