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.

X-ring_O-ring

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. The perfect chain-for now!

Burman transmission  (gearboxes and clutches)

Burman & Sons Limited, manufacturers of horse & barbers’ clippers, sheep shearers and steering gears also built gearboxes that many of our old bikes run on today.So here’s something on understanding those trannys and keeping them in good nick.

The ‘CP’ and  ‘GB’ aka the ‘B52’ gearbox was introduced in 1952 and were used on a number of machines are covered here:
