Late build

NOTE
Do not remove the oil rail end plugs or acoustic wave attenuator port fitting. Service parts are not available to support the components.

  1. Remove the bolts and the high-pressure oil rail.
    NOTE
    The rings on the crankcase-to-head tube are to be used to pry the tube assembly from the branch tube assembly or the oil rail assembly.
  2. Remove the crankcase-to-head tube assembly.
  3. Remove and discard the O-rings.
    WARNING
    Do not pull on the glow plug wire or damage may occur.

WARNING
Install new D-ring seals on the crankcase-to-head tube. It requires several hours after installation for the D-ring seals to relax back to their original size. If the tube assembly is installed before the D-ring seals have relaxed, damage to the D-ring seals can occur.

  1. Install new D-ring seals on each end of the crankcase to head tube assemblies.
    NOTE
    Use care to avoid scratching the blue compound on the cylinder head gasket.
