Putting in main bearings into a 1986 Chrysler LeBaron Town & Country Wagon (before they assigned Town & Country to the minivans). Big ol' cast iron unit that is chain driven with two counter-rotating shafts. Only information I can find is that they are 'balance shafts'? What is the purpose of this unit, and does it have to be timed? (person already removed it from car).
