Hah, you guys put too much faith in me; I have never measured those.
But I can tell you anther thing; I have never had to struggle to put those in!
And a third thing is I have never removed the circlip.
But the rollers do have to be perfectly parallel to the centerline. Which I just make happen as I feed the last on thru the slot.
Those rollers do so little work, I would not be afraid to reuse the old ones. The ones in mine are probably circa 1969.
