Maintenance Manual Bsa M21
Manuals, Services sheets and anything that has made my bikes run a little better and life a whole lot easier, it’s all here. If anyone feels that I’m violating any copyrights or stepping on anyone’s corns-just let me know. If anyone needs something in particular ping me back and let me know what you are looking for and if I have it, I’ll scan and put it up on here. What are O Ring and X Ring chains? There are three principal types of roller drive chains: O Ring less, O Ring and X Ring. The O Ring less types date back to the beginning of time and are still used a lot today. They are strong, light, cheap to produce and relatively friction free but they do not have internal lubrication, so they tend to wear out more quickly.
Chain design has had to improve with the technology of the motorcycle. With today’s bigger and more powerful bikes, normal O Ring less chains have lost out ‘O Ring’ and ‘X Ring’ chains. These two types of chains position a sealing ring between the inner and outer chain plates. Before riveting in the factory, the internal parts of the chain are filled with chain grease by vacuum. The sealing rings keep the internal lubrication in, and the dirt out, thus preserving the durability of the chain.
O rings are literally ‘O’ shaped. As the two plates push on either side of the O ring, it distorts to have two flat sides to its shape. This is great on sealing and but creates a lot of friction which saps the bike’s power. To reduce this friction ‘X Ring’ chains were developed. ‘X’ describes the shape of the ring. Instead of having an O shape it now has an X shape.
This means that when pressed between the chain plates, it has two smaller faces touching either plate in an X shape. This gives you the same great sealing and durability but now with very low friction.
