ZF 220 A oil service

[Bob Hruby]

I am about to change the oil on my transmissions:

1. SEA 30, per manual?
2. Where is the filter screen?
3. How do I clean it?
4. I understand that I want to change the oil within 2 minutes of running it?
5. Is there anything else I need to know?

Thanks.

Yes, SAE30 and 3 liters is the listed capacity.  I always check the level before draining and then measure what is removed and use that as a refill reference and then adjust slightly if needed.  See the attached documents for some additional info and diagram.  As to cleaning the screen, I wipe it clean, blow it out and then flush with new oil.  You can use something like mineral spirits if you feel the need but always finish your rinsing/cleaning  the new clean oil.  The 2 minutes you mentioned is for checking, not draining.  As to anything else, yes, removing the magnet/screen hex nut needs a little added attention over your usual drain plug.  The two issues are that it is TIGHT and it is very shallow.  See the below link as to modifying a 36mm socket to get a full bite on the hex.  I use a breaker bar with it.  And the drain plug is 22mm.
