The hydraulic filter on my Bobcat is heavy duty and expensive ($60). There are two.
I cut one open and it took a lot of grinding. My filter cutter would not touch it. When the "can" was off you can see a super heavy base and the can is made of thick enough metal that you cannot squish it with your hand (well my 60 yr old hands at least).
A XREF would be fine, but I would not just get one that fits.
