speedometer gear

The little seals are a pain to change, but like the post above you have to have the right numbers for your gear. If I remember right there are two seals inside.

Yep, and this is one of them held in by a little steel ring.
The other is an oring around the outside of the round housing.

Notice there is room for two of those little seals inside the center, and we used to double them for extra sealing.
