Bobcat 331 Return to Tank

[TSXJ1197]

hey guys, first post here!

I've been wanting to get a flail mower attachment for our 331 but to my understanding it has 3 lines. supply, return, and case drain line but our machine doesn't have an aux case drain. I hear there is a kit but I'm unsure of where to plumb the aux drain to? Can i essentially get another filter assembly and plumb it in before the motor case drain filter or will this cause back pressure issues? I believe the 334 has an aux case drain and that they're essentially the same machine just has more power.

Any advice would be helpful!

Thanks,

Nate

Tee the case drain line into inlet end of the case drain filter, no extra filter needed. 334 is a 331 with a longer dipper arm no other differences if in same production era.
