The Crankcase Bolts were undone in reverse order to that shown in the Service Manual in 2-3 steps. The Bolts were then cleaned and placed in a Cardboard template ready for later assembly (Don’t laugh, said I got a memory like a sieve and yes I am being a very pernickety but, will save me time sorting out which Bolt is which when assembling LOL).
Following NSR WORLD’s advice in their Rebuilld Section https://archive.nsr-world.com/ and using a soft block of wood, the bond between the 2 halves of the Crankcase were split by applying some leverage to the underside of the inlet manifold, and on the lower cylinder, by tapping the casing upwards.
As stated previously the offending Crankshaft was removed and sent away for a total rebuild (little did I know at the time what had actually gone so terrible wrong with the Centre Seal & Bearing. Please see images in above posts).
