xvii.

Place the Inlet Crankcase (2) in its correct position over the Shaft and Barrels (the oil

filler should be at the top between Barrels 'A' and 'H').

xviii.

Push the Inlet Crankcase (2) over the Barrels until the threads of Bolts (99) engage.

xix.

Tighten Bolts (99) until the Crankcase halves are completely together. Care should be
