when i got my 400 the front wheel and carbs were in the basket. I
think I got the carbs back together but I'm having trouble what parts
come out of the basket and go on the front wheel. The books suck and
the parts fisk don't tell me what some things are made of. I have two
pairs of felt washers of different thicknesses and have a suspicion
where they go [drum break] but only kinda sorta. does anybody know
this stuff? HELLLP!!!

The felt washers probably have nothing to do with the brake or axle or
the speedo drive as mechanical spacers.
The only thing I can imagine they would do is act as a dust seal.
Buy maybe they are foreign parts that somehow wound up in the box with
everything else.

motogrid, yamaha 1981 xs400h front wheel, could parts 11 and 12 be
made of felt? has anybody assembled this wheel from that vintage?

#11 is a shim that would be made of steel. #12 is an oil seal that
would be steel covered with rubber.

I have assembled many wheels from that era and have never seen a felt
washer in any of them.
Like I said, it's possible that the washers are extra parts from some
other machine.

Others here may know this bike whereas I don't so I can't answer the
specific question but I do know that some drum brake assemblies have a
felt washer that goes around the brake cam immediately on the outside of
the drum and the service manuals will say to coat the felt with oil when
assembling. I guess some designs need it more than others to help keep
road dust and moisture out of the drum. But the parts manuals sometimes
call it a seal, not a washer, eg:
http://www.bikebandit.com/houseofmotorcycles/yamaha-motorcycle-xs400sh-1981/o/m8262
(see part number 20 from the rear wheel, doesn't seem the same bike as
the front wheel on this one would seem to have a disc.)
On the other hand, maybe those felt washers are meant to go on the floor
- I've seen a few there after watching people put hubs back together!
