Share This Post

Alright guys, here it is, the most requested video! This 4 hour long video walks you through complete disassembly and reassembly of your Honda CB bottom end.

Year, Make, Models Covered

The video 100% covers all CB550’s. The CB500 has a different trans and clutch setup, however I think this video will get you 90% of what you need. This video will also pertain to CB400 & CB350 models.

Part Restoration

This engine looked terrible when I bought it. After everything was disassembled, I degreased parts in my solvent tank,  and then soda blasted the cases and covers. The soda cleaned them up nice, however did not restore the finish. I decided to get the parts vapor blasted by Vapor-Shine in Naperville, IL. They came out looking brand new! And for the covers, I decided to polish them, so make sure to check out that video here.

Parts

I bought OEM Honda parts from Rocky MTN ATV if they were available. Searching the part number on ebay helped out since there are NOS (new old stock) of some parts still available. Ebay was a great help for buying used parts as well. I must of placed a dozen orders on ebay since there were a lot of parts that needed replacing.
