Cylinder Top and Bottom Covers: Parts 5, 6a & 6b

  • BOOK: The stud locations for the covers are not well dimensioned. Care needs to be taken as they can break into the ports. This is particularly likely to happen as the covers are drilled first and then spotted thru to the cylinders, and the clash is not obvious until it is too late…
  • BOOK: Similarly, the holes in the lower covers to attach the covers to the rear columns are not dimensioned at all! I concluded that the two outer ones should be 1.875″ from the cylinder centerline and the centre one 2″ from the cylinder centreline – this worked OK for me…
  • BOOK: Two of the cover bolt holes on the lower HP cylinder cover (and one on the upper HP valve chest cover) are shown as blind – this can’t be right!
