Why would you want to knock it out?

But I am curious what that part of the engine is all  about..



Ned,
 
When I overhauled my 79, I knocked out the balls to make sure the  engine was 
clean throughout.  One end of the oil galleries has  threaded plugs and the 
other end has interference fit steel balls.  I think  there were 3 total.  I 
used a long piece of 1/2 inch round stock to do the  job.  The balls are not 
something you want to forget as they plug the end  of the engine in the bell 
housing area.
 
Regards.

Ned -
I don't have a 124 manual to check out, but generally the steel ball is used
to plug an oil passage after it is drilled. You can't always machine a dead
end hole, so they drill all the way through and then plug the openings that
should end up closed. When you are trying to clean out any accumulated
debis, you want to open the passages back up for access to get proper
cleaning and verification of cleanliness by inspection performed by looking
through the hole and/or blowing air through it.

I believe it provides a means to rod out and  clean oil passages.  I don't
think its done unless the block is out of the car.

Routinely done when the engine is rebuilt.
