Yes the crank is in 2 part joined in the centre with Allen bolt on a taper. The crank case covers come off either side. Very easy to strip. I made a puller to draw off the crank covers.

Hi There.

Well done so far, a fantastic restoration. A previous nieghbour of mine had an Ariel Leader ( is that the 250c version ) Looked pretty nippy too. He once told me you could completely strip down the engine of all major components, without removing the engine from the frame. True or false.

look forward seeing the finished item.....


The Leader was always a 250cc and the Arrow was up till the last year and a bit of Ariel production when they introduced a slightly cheaper 200cc model to get into a lower road tax and insurance bracket. Total of 854 200s made. The engine is weird in that I bolted the bare crankcases into the frame and built the bike off the engine! Crank is a 2 part thing where a half threads in from each side and has a cover with oil seal on each side. Gearbox is like a cassette box in that the whole box slides in on the outer cover. I'll stick a video of it running when I get there. This one is being a pig due to it being badly stored. Just off to repair the speedo next.


Cheers Col
