Changing the Fork Oil, first time

[mrcasual666]

I'm changing the oil in my forks ('92 K75S) for the first time. Pretty basic question:

The shop manual recommends changing the sealing washers on both the fork drain plug and filler plug. Makes sense. But I can't figure out which parts to order.

I assume #7 is the drain plug washer. But I can't figure out where the filler plug washer is. Am I missing something?

The slider shown in the drawing is from a Fichtel & Sachs, if you have a -92 you have a Showa fork.
The drain gasket is identical, but just mention it...if you later on gonna order other fork parts.
On the filler plug a o-ring is used, part #31 42 2 312 714, shown in the diagram together with the stanchion.

Those drain plugs are notorious for getting stripped.  Be exceedingly careful when replacing it.

I stripped my drain threads the first time I changed the fork oil. I was able to use a longer screw and Locktite to put it back together 50k miles ago.

Ever since then I've drained the fork oil through the hole in the very bottom of the fork (#12 in first post).

suspension fluud getts real nasty real quick... dirty fluid drains better when its hott... so the best time to drain it is right after a long ride when its still hott...

Another trick for draining oil is to heat things up with a radiant space heater.  Takes a while, but I have used it successfully to heat the oil pan for an engine oil change in a sub freezing garage.  For the oil pan, it would have been even better to use an electric hot plate.

Thanks for all the feedback, I'll let you know how it goes.
