Engine balancer assembly — removal and installation
1. Remove the engine.
2. Position the engine at TDC compression for cylinder No. 1 (see Top Dead Center (TDC) for number one piston — locating). Disconnect the negative battery cable (see Engine electrical systems).
3. Remove the engine oil pan (see Oil pan — removal and installation), then remove the oil strainer mounting bolts and remove the strainer.
4. Remove the oil baffle plate mounting bolts and remove the baffle plate. Then remove the balancer assembly mounting bolts and lift the assembly off of the lower crankcase.
5. Before installing the balancer assembly, check that the alignment line mark of the balance shaft damper cover and dot on the balance shaft driven gear are aligned.
6. If the alignment marks are not aligned, place a wrench on the rear cutout of the No. 2 balance shaft and hold the assembly.
7. Rotate the balance shaft gear of the No. 1 balance shaft counterclockwise to align the alignment dot of the balance shaft gear with the alignment mark line of the balance shaft damper cover. Make sure the balance shafts stay in this position until the assembly is installed.
8. Turn the crankshaft 270-degrees clock wise so the keyway is aligned with the bottom of the cylinder block (see illustration).

9. Check to make sure the cutouts at the rear ends of the shafts are facing each other (see illustration).

10. Install the engine balancer and tighten the bolts in the proper sequence (see illustration) to the torque listed in this Chapter’s Specifications.
