Thanks Chuck for the reply.

Well got the crank bolt off. Logged a screwdriver through a hole in the balancer to the block. It did not take 400 Nm to get it off at all, but with little effort. Must have been pretty loose. Happy I checked it now. Have a vision of the darn thing flying off and the damage it would have caused. The cup springs are about flattened, lost their cup(ness).

The bottom line is the balancer has its pins and are in the correct place. Looks like someone used a slege to get them in as they are pretty flat and gouged.

Well guess this has gone full circle now. Back to the timing chain.
