So I pulled the crankshaft this morning

Seems that you can just remove crankshaft and leave the piston assembly in situ....(I may buy a ring compresor and push pistons out anyhow). The blocks of wood were to stop the pistons sliding down and dmaging the heads/valves.... they stayed in place though.

If you look at the crankshaft and on the centre journal where the balance rod locates you can clearly see its damaged. Looks like a new crank is needed! :(

Running out of room on the bench now!

I have tried to phone BMW this morning and am waiting on a phone back. The bike has full service history and only covered 14/15k miles. In my eyes I don't think the engine should be having a major failure like this. Am goingto try and get them to pay for the spares and rebuild kit (gaskets etc).... they havnt had to pay for the labour as Ive done it and will be rebuilding myself.... will let you all know how i get on.

Parts now required list:
  • Oil and Filter
  • Antifreeze
  • Alternator (Right hand side) gasket
  • Clutch (Left hand side) gasket
  • Rocker Cover Gasket
  • Crankshaft
  • Balancing Rod connector bearing shells
  • Balancing Rod connector bolts (stretch bolts)
  • Main bearing bearing shells
  • Main beraing connector bolts (stretch bolts)
  • Piston con rod bearing shells (two sets)
  • Piston con rod bolts (two sets - stretch bolts)
  • Crankcasing 4 off stretch bolts.
  • and....inner clutch basket (clutch driver dog) as I broke my one trying to remove bolt...oooops
