@Jodi Looks like a one way bearing. Amazon is the place to get it. Make sure that when you install the new one, that the letters on the bearing are facing towards you (away from the engine). We replaced the whole wet clutch system and ours now works great. There is a great video on youtube on how to do it. Took about 4 hours with me and the kids. Here is a link to the part we used. https://www.amazon.com/dp/B07DNQMT9L?ref=fed_asin_title Also here is a link to the sheave that we also replaced while doing this. https://www.amazon.com/dp/B0C1JLSX2C?ref=fed_asin_title Here is a link to the belt that we used. https://www.amazon.com/dp/B092YZ69T5?ref=fed_asin_title Ours is a Cub Cadet challenger 700. They are all the same for the most part.

Which way does the air filter go with the hole at the top or bottom?

The air filter should be installed with the correct orientation by aligning it with the air filter door. The air filter door has an unlock and lock position, and installation requires turning it one quarter turn to lock. The specific position of the hole (top or bottom) is not stated.
