1/8th.
i was surprised the shaft wouldn't come out the handle no matter what i did.
i was gonna jb weld it in iffen it came out.
someone was in it before and messed with the half ball area of the handle trying to get a roll pin installed. i'm not sure how the stem was held in the handle from the factory.
hope it works for u.
