	the crankshaft above the pump pulley
	must face the engine.
	The hub collar of the pulley (5) must face
	downwards.

	isolators (22) in the engine bed (small
	diameter end in the engine bed hole).
3.	Check that the clutch tie down (10) is not
	deformed (straighten if necessary) and
	lower the engine into position. The
	engine weighs 40.5 kg.
