4718 Removing hydraulic pump filter for cleaning

Hi, this relates to the screen filter attached to the pump in the rear drive housing. I am wondering how to get at the screen filter. I know I need to remove the bottom cover. Does the pump and filter come down with this cover or remain in the housing. If they come away, is refitting easy, do I need any new seals etc. Any info would be great.

HI
Pump and filter comes down whit the plate, you need new gasket for the cover and two O-rings for the conectorpipe.
