There is danger of pieces flying during the replacement

glasses and gloves.
Replace the teeth before they wear down as far as the adapter.

the bucket to prevent the bucket from coming down.

Put a rod (slightly narrower than the pin) in contact with the
hatched portion (either left or right) and tap pin (2) out to the
opposite side.

hand, then knock it in with a hammer.
