Confused Sturmey Archer Hub, Part 2 - Opening it up


I got it opened up today, i have only opened up a couple before this one, but i will say this, it was fun to see inside it.  The first time i did this to a single speed with a coaster brake, i never got it back together.  
I have been fast teaching myself things about internal hubs and lacing wheels. 
 I watched this video: http://www.youtube.com/watch?v=mIU6mi0K4Y4.  
It shows you how to lace a 36 spoke hole BMX bike wheel, but it's all the same just different size wheel.
As far as learning about internal hubs, I've been listening to Dan and Diane at the shop, as well as 
internet research. 

It took me about half an hour to open it up and close it back up, and here's what and how i did it:

First i took out the pin, then took off the nut, washer, lock bolt and the bearing cup.

after i took the bearing cup off, i took the spring out and the cog.

 what the spring does is pulls the pin into the hub by pushing on the gear, 
for when you shift from gear to gear.

I laid the parts out in order of how they came off, so i wouldn't get them mixed up.


That piece inside that looks like a "X" that is the gear.  
Really there is only one gear inside, and when you shift the gear, it catches on
lumps inside that make up 1st, 2nd, and 3rd gear.  
I tried to get a good picture of it but it didn't work real well.  
I got everything pulled out and looked inside,
and was able to see that it was a three speed hub.
These hubs are sometimes a pain to calibrate with the shifter, from what i have experienced.
I put some Phil Tenacious Oil into it and some Poly lube 1000 onto the bearings.
Phil Tenacious Oil is really good for internal hubs

After i oiled and greased it up, i started putting it back together, 
but when i started to do that i put the cog back on and then the bearing cup, but i forgot to 
include the spring on the axle under the bearing cup only after i got the cup half way down 
the axle.  i wasn't paying attention to what i was doing, i had gotten interrupted by a phone call.
It looks good now that i got it back together.  I am going to lace it into a 700c rim, but not sure what bike i'll
put it on. When i get it laced up, i'll blog about it, it probably won't be until sometime next week though.

Keep on Biking....
