The table below the schematic is the spare parts list for the CB550K '78 US.
The first column called "img#" is the reference to the item in the schematic.
The second column, called "quantity" tells you how many times a part is used in the image. The column "part" is a description of this item. Clicking the link, brings you to to the product detail page.
The "price" column always shows you the price per item. When the "Area" column is not empty, then it gives you valuable information for which geographical area the product was made for. Be sure this matches with you vehicle's area. The last column, called "Serial#" refers to your bike's serialnumber.
Before ordering a partnumber, please check carefully if the serialnumber corresponds with you vehicle's serial number.
Finally, you can also click the link "big image of..." to see the large version of the technical drawing in a new window. You should disable popup blockers to see it.
