Can anyone tell me if a 2012 Bobcat T750 has a case drain filter? I can not find one on my machine. I'm talking about the kind thats in a little cylinder and made of bronze. On my machine all of the case drain lines come together to an aluminum manifold and from there goes into the side of the pump. I'm going to be changing a final drive motor and every shop/dealer has told me to change this filter. I've told them I can't find one on my machine and they all say it has to have one. I've looked at schematics on bobcats website and it does not show one there that I can see. Wondering if I'm looking in the wrong place? Any help would be appreciated.
