Here is the page from the shop manual and parts catalog; carefully inspect, clean, and grease as necessary. As others have said, pay particular attention to the pawl assembly. There is a left and right version, and they are not interchangeable.
You can buy a paper copy of the shop manual from Honda's store on ebay or amazon; free shipping and updates for three years. Here are the links:
