What is the proper installation of balancer

Hi to all
Anyone who can assist me with my problem? I am having a camry car that having a problem on timing mark for balancer shaft, I would like to pinpoint the exsact location of pin mark before procceding with the installation, in either for me to make it sure that I install the parts properly.

Thanks to anybody who can advice in regard to this matter.

Well Joel, This should help, but you didn't say what year so I took a stab. There are spacers, or I like to call shims between the block and the BS housing.
This properly sets the backlash. Re use those just as it came apart and all should be OK.
