Berg will balance the crank, flywheel, pressure plate, fan, pulley 
and even the driven disk. The pistons are matched for weight and 
the rods are matched end-for-end for weight.

Even the factory parts are balanced somewhat. Cranks, flywheels, 
and pressure plates when new, had their heavy sides marked and 
when assembled at the factory they were careful to put them 
together with the marks spread around and not all on the same 
side. Thus, when disassembling a "virgin" engine, it is a good idea 
to keep all the parts in their original orientation.
