Just get a new spinner for the top. I believe it's attached to the pig tail and it's probaly a good idea to replace that anyway if it's been a while. Another thing to think about is if that thing is binding that bad it may fall apart and you know what that means.

The jumping off haylard is easy to fix. Pull the pin that the shive pivots on and remove the shive. Use vise grips,vise or something similar, squeeze the outer shell of the block closed a bit then reassemble. Just like new.
