The nose of the cocking lever where it meets the hammer tails to cock them is a fitted area. Metal has to be removed here until the lever just cocks the hammers, and no more. Did your new lever have extra metal in this area as compared to the original? If this area is not fitted it will put tremendous strain on the whole system and could be the culprit of your bent lever.

Hope this helps.
