  1. Lubricate the camshaft lobes and camshaft bearing journals and insert the camshaft (1). NOTE: Ensure that the plate is installed on the correct side. The fasteners are flat head fasteners so the top of the head of the fastener should not stick above the front face of the plate after they are torqued. The plate has chamfered fastener holes and the chamfered side should be facing forward to ensure the fasteners are flush or below the front surface.
  2. Install the camshaft thrust plate (1).
