Realign Idler Pulley and Chain

What happens here

The idler pulley is found to be off the chain and out of its proper position. Use a wrench to loosen the bolt securing the idler pulley. Slide the idler pulley back onto the chain and into the correct alignment. Tighten the bolt to secure the pulley in place, ensuring the chain has proper tension without being too tight.

Goal: Correct the misalignment of the idler pulley and chain.
