Reinstalling the bottom bracket.



1/4 inch bearings required

The adjustable cup and lockring before cleaning and repacking

After cleaning

First layer of grease with 11 1/4 inch ball bearings packed in.

Another layer of grease on top

Drive side of spindle (I hope, this side was a little longer) with a layer of grease and the 11 1/4 inch bearings packed in 

Another layer of grease on top

Adjusting the adjustable cup was difficult because;
1. it has wrench flats instead of pin holes
2. the wrench flats are too large for any non-adjuctable wrench I own
3. the lockring notches are too small for any lockring tool i own.

The wrench flats are 1 1/8 inch (28.575mm). I ended up using an adjustable wrench, and since this is not put on tight at all, it worked fine.

After a lot of searching and trial and error, I found this VAR - 78 tool worked very well on the knurled edge of the lockring.

I haven't fully inserted the cotter pins yet, but wanted to see it look a bit more like a bike. Quite please with how the chainring/cranks have cleaned up with the evapo-rust. (the cotter pin nut and washer are in there now)
