I have the engine out of the car and I had to remove the harmonic balancer, I did not have the proper puller and for some reason I used a wooden piece and a rubber mallet to tap the balancer off the crankshaft. I was then able to pull it off by hand. I am now wondering if I have caused damage to internal components? (thrust bearings)
EDIT: Mercedes M103 engine from a 1991 w124 300E The balancer is held by a bolt (torqued to 400nm) and a woodruff key.
