New Barnett clutch plates arrived today and were soaked in engine oil prior to fitting.
I drilled an extra oil feed hole closer to the face of the hub to improve oil flow to the first plate which I believe was the cause of the original clutch failure.
This photo shows the position of the original oil feed hole which was not far enough over to align with the first plate.
I also tried my twelve point socket on the clutch nut and it fitted without having to be ground down. What is all this nonsense about having to grind down a socket?
With the clutch basket in position I managed to undo the lower bolt of the oil pump drive chain tensioner and eased the tensioner over slighty to reduce the slap of the chain which appeared to me to be rather excessive.
I'm not a fan of the BMW Club although I used to be the Chairman of the London Section many years ago. I know that the BMW Club has a selection of tools although probably not for the K1200S.
Sometimes I find that BMW uses strange methods to complete some tasks necessitating the use of some weird special tools. For instance the procedure and tools required to adjust the oil pump drive chain are a joke.
