How do these come apart?
S-53 and S-52 Williams Superratchet,  The 53 is stiff the 52 is OK but would like to clean and lubricate.

This thread goes through it. Depends on how far down you want to take it. Getting the main drive out is easy the segmented ring on the top is the retainer nut. Taking it apart further is a bit fussy but can be done.

They are great ratchets and worth doing.
