82 300dt horrible re-occuring crank balancer issues

[willjohn123]

First, what are the two pieces of the balancer called? The large disk and the part that slips over the crank with the pins? I need the part that slips over the crank so I want to be asking for the right thing.

Here's the story: I have had a reoccuring problem the entire time I have owned this car. The crank pulley wobbles, which has sheared off the PS pump bolts on one road trip, alternator bolts on another, after that I tried a new pulley, worked for a while. Then the crank sheared off the pins for the balancer. Got new pins, but I must have not put the balancer on straight, so it hit the oil pan and instead of shearing the pins, they rolled and carved out the balancer, so now the balancer is stuck on good. If/when I get it off i will run it to make sure the crank is not bent, then I will try a new balancer and see how long that lasts.
