In some cases where the OEM balancer has been replaced this locating feature cannot be used. VMAC has developed 3 adaptor kits to address this issue on the various VMAC systems and vehicle models: A900014, A900015 and A900016.   Resolution: Installing the VMAC Crank Pulley: □ Place the OEM crank pulley on the front of the crankshaft and rotate it to align it with the locating pin. Route the belt as per (Figure 1.1) but leave the belt loose. Note: Do not tension the OEM belt before the OEM crank pulley bolts are torqued. □ Place the VR pulley in front of the OEM crank pulley and align it with the locating pin. Ensure the OEM belt is routed around the OEM crank pulley before installing the VMAC crank pulley. Figure 1.1 – Belt routing □ Apply Loctite to the four supplied bolts and flat washers and install them through the two pulleys into the crankshaft. Torque the crank pulley bolts to 69 ft-lbs. □ Check the OEM belt routing diagram for the correct installation (Figure 1.1). □ From this stage forward continue with the steps in your installation manual
