Matty, I bet there is a (reasonably) easy way to do it. I remember the first time an Outdoorking member put new clutch facings on a Greenfield he had a difficult, ugly job to do, but he did it anyway. Since then each time a member has done the same job it was a lot easier, because of what had been learned.
Do you know a servicing agent who has done a lot of these? A five minute chat with their mechanic would make a world of difference.
