□ Install fan stator using OEM nuts.
□ Remove the 4 OEM crank pulley balancer bolts and discard.
Install VMAC crank pulley on inside of OEM balancer. Ensure
center-locating boss goes in OEM balancer and install the 4
supplied M12 crank pulley bolts. Torque to 22 lb. ft. (will tighten
an additional 90 degrees in step to follow).
Some concerns have been raised regarding the OEM 2011
Ford 6.7 harmonic balancer. The concern is related to the
flatness of the balancer surface which the VMAC crank
pulley is mounted to. When the pulley is installed on the
balancer and the engine is running there may be a front to
back wobble of the VMAC crank pulley which can cause
damage to the driveline components.
If you are experiencing this issue please contact VMAC
technical support at 1-888-241-2289.
□ Tension OEM belt and ensure belt seated properly on all pulleys,
(Figure 3.13 – OEM Belt Routing).
