May I ask why?
The chain has been known to break the roller out of the frame, leaving a big hole in the frame. Although some argue it is ok to leave it on, I personally don't see the advantage.
There has been no problems ever reported (that I am aware of) from removing it. The general consensus is to just remove it and forget it.
Some with good fabricating skills have moved it to a different location.
