Just replaced the 'O' ring oil seal on my Ba's dizzy. Used the instructions from a previous post by Mark T and smotter. Any how the seal cost a mere £1.83 from Mazda but if you want to source your own the diamentions are,

Internal bore 38mm
External diameter 44mm
Thickness of the seal (looking edge on) 4mm
Thickness of the seal (looking at it from the front ) 3mm

The whole job took no more that 30mins.

Thanks Stuart.

You're best off getting the Mazda one as there are so many different materials for O'rings. You'd have to know your onions to get the right one otherwise

Not wrong mate. There not rubber any more. (Hmmm rubber) . Had a look on a few site that sell seals and 'O' rings. As you say best to spend the £1.83 and save the hassel.
