I've removed the old rear sprocket, seperated the carrier flange from the sprocket and removed the cush drives.

Is it necessary to have a new flange bush machine pressed into the new rear sprocket? or can I remove the old one from the previous sprocket and reuse? (if so how?)

#7 in diagram below..

Also when I test fitted the cush drives in the new sprocket they slide right through is that normal? or should they be somewhat fitted? they were very tight on the old rear sprocket.

Thanks in advance.

Nothing need to be replaced, you can re-use the "old" stuff, just clean it of course.
The cush drives might have collected dirt etc over the time, thats why they were a bit tight in the old sprocket.
Would also change the front sprocket and chain and/or switching to a 520 set.
