Thank you Q8 for the full documented explanation.

I am planing to change the oil on my 2012 3 wheeler tomorow. I realised that I did not find folowing intruction in the Morgan User booklet:
- volume of oil in the bevel box?
- what is the size of the drain plug? In your instruction, you mentioned plug #25, but I am not sure it was meant "item #25" or "size 25 socket".

Thanks guys in advance for your help and answers,

Cheers from Vienna, Austria
