Hello all,
I am looking to see if you can guide me to the locations of the drain locations for oil on my rtv.

I got a rock stuck between the back plate and the yellow oil filter (I believe the hydraulic filter) and it is now leaking at that filter.


Does anyone have a manual that shows the drain locations. Also when changing that filter out do I need to do anything specific to get air out of the system?

Also it looks like I must use the Kubota super udt2 oil rather than a alternative oil? What is the other oil filter behind the yellow one?

Thanks for the help!

The air will work itself out, fill to the marks on the dip stick. Run the engine to fill the new filter then recheck dip stick level.
Use Super UDT2
"other oil filter"??? Pictures would help.

You can get the manual here:

I don't own an ATV so I'm taking an uneducated guess.
The smaller black one looks like it's for the engine oil.
The bigger yellow one looks like it's for the transmission.
The WSM should guide you.

Do you have the owners manual? 2nd hit on google has a free operators manual.

Edit. I stand corrected. Refer to the post below this

The operators (owners) manual has the filter/oil change info:

The black filter in your picture is the hydraulic oil suction filter. (Engine oil filter is on the engine block.)
Yellow is the transmission (HST) filter. They both filter the hydraulic oil.

See also my post on changing these filters out:

When changing the suction filter, the hydraulic oil will flow/drain out of the tank when its off.
Be ready with the new filter to minimize oil lost.
