balancer

I split my cases to repair the notorious second gear issue. Since getting all my parts back from Sean today, I started reassembly and came to a snag in the process. My book (clymers) says there is supposed to be a timing mark on the main drive gear on the crank and a mark on the balancer shaft...

Can the ballencer on my 86 max give a two tone knock like a rod from the berings on either end of it got great oil pressure dosen't sound bad cold after warms up just sounds like a rod bering
