Turn both balancer shafts (1) until the flat part on each shaft is away from the oil pan plate. Install two 3/8"-16 NC bolts (2) 1 1/2" long through the oil pan plate and into the holes in the balancer shafts. This will prevent the shafts from turning. Tighten the bolts until they are against the bottoms of the holes in the shafts, then loosen the bolts 1/2 turn. 3. Put oil pump (3) in position on the cylinder block and install the locks and bolts that hold the oil pump in place. Connect the scavenge line to the oil pump. Make sure there is a new gasket between the oil pump and the scavenge line.4. Remove bolts (2). Check to see that the balancer shaft timing is correct. The balancer shaft timing is correct when the holes in the balancer shafts are in alignment with the holes in the oil pan plate and No. 1 piston is at the top center compression position.end by: a) install oil pan
