Important:
^ On vehicles equipped with RPO HP2, the rotor and flexplate of the electric drive unit MUST be installed to the rear of the engine prior to crankshaft balancer installation.
^ The crankshaft balancer installation and bolt tightening involves a four stage tightening process. The first pass ensures that the crankshaft balancer is completely installed onto the crankshaft. The second, third and fourth passes tighten the new bolt to the proper torque.
^ The used crankshaft balancer bolt is used only during the first pass of the balancer installation procedure. Install a NEW crankshaft balancer bolt and tighten as described in the second, third and fourth passes of the balancer bolt tightening procedure.
Install the J 46093 (1) and bolts. The flange of the tool should locate into the hole in the flexplate. Use two M10 - 1.5 x 40 mm bolts for proper tool operation.
^ Tighten the bolts to 50 Nm (37 ft. lbs.).
