Once the counterbalance weight is installed, install the crankshaft into the motor case.

Then, install the counterbalance weight shaft in the bottom of the motor. It seals with an o ring into the block, replace if necessary.
I just reassembled my engine yesterday. A trick I figured out is to not put the counterbalance shaft in until after you torque the rod cap bolts. Once you torque the top rod bolt, rotate the crank and swing the counterbalance down so you can get to the lower rod bolt. After that you can put the counterbalance shaft in.
