6.4L vs 6.0L Flexplate
• The flexplate for the 6.4L automatic equipped engine
uses an 8 bolt torque converter bolt pattern.
• The flexplate for the 6.0L automatic equipped engine
uses a 6 bolt torque converter bolt pattern.
NOTE: Yellow circle added for bolt circle reference.
High Pressure Fuel Injection Pump &
Rear Geartrain
• The geartrain for the crankshaft, camshaft, and
the high pressure fuel injection pump are located
in the rear of the engine under the rear cover.
• This allows for the high pressure fuel pump to be
mounted inside the engine and also reduces noise.
• The high pressure fuel injection pump turns
at a ratio of 1:1 with crankshaft speed.
NOTE: The helical cut gears used on the 6.4L
differ from those used on the 6.0L.
Rocker Pedestal
• The rocker pedestal is secured independent of
the cylinder head bolts, which no longer need to
be removed to service the rocker arms.
Rocker Pedestal
