Hello Forum, having recently learned about case drains and filters on this forum, I realized this step was missing in my preventive maintenance program. So I was into the bobcat 873 f series and found them, opened them up and .....drum roll anticipation...found them with no debris, but changed them anyway. So, realizing I never looked for case drain filters on the 753, I pulled that machine in, opened side plates and cab, and found none filter canisters on the case drains. I see from the existing case drain lines and routing they would be easy to add with 3/8 JIC fittings. The question is, should I? The 753 has no drive issues, but I like the idea of the added protection to keep metal debris out of the hydraulic system should drive motors take a dump. Experience with this? If recommended to do so, should I put them in line at current case drain line terminal ends? Thank you in advance.

Reaper man, I followed the case drain hydraulic lines to the point they attached to other areas. The right side drains into what looks like a valve bank. The left side drains near the main hydraulic pump. There were no filter canisters in these lines. Are you suggesting they may be somewhere else, but not directly attached to the single case drain line coming from each motor drive? Thank you...

Let me take a photo of mine tomorrow and I'll put it up for you to see.
Following up on this, the bobcat parts manual shows my SN did not, would not have case drain filters in the lines. So does anyone here think that I should/should not add them? Any unintended consequences to be concerned about? The standard bobcat aluminum case drain cartridges could easily be added to existing case drain lines with correct hyd fittings. It seems to make sense to do it, as the protection afforded to the hydraulic/hydrostatic pumps is important. Bobcat added them after my SN series! thoughts?
