It seems to me that there is a oil screen in the front pump somewhere under a plug. I'm not sure which plug though. I believe it may be under one of the piston plugs. Should be able to access from under the tractor. Not sure though as tis been a long long while since I have messed with a pump like those.
Maybe someone else can chime in.
