Crankshaft Counterweight Balance Weight Removal & Installation on
Mercedes 280 (110 Series) Engines
Removing the front balance plate from Mercedes Benz 110 engine series crankshafts can be quite difficult, especially since the balance plate is riveted to the crankshaft.
AERA members have developed a procedure that is safe and cost effective:
1) With a 3/8 end mill, remove the head of each of the four rivets that attach the plate to the counterweight.
2) Simultaneously drive all four rivets out of the crankshaft to prevent distortion of the plate.
3) Refinish the crankshaft as required.
4) Install the plate by pressing 4 new rivets, Mercedes Benz Part No. 000661 006013 through the counterweight and into the plate.
5) Hold the plate to the crankshaft counterweight by wedging a 5/8 or 3/4 bolt, cut to length, between the second counterweight and the plate. Position the cap screw end of each bolt right underneath the plate countersink. This will mushroom the end of the rivet, securing the plate.
