just putting friends drivetrain back together on his 03 mviper and see that the keyway is sloppy in the jackshaft.when the disk is installed there is about 1/4 " rotating play.the keyway is also loose in the brake disk.i had no idea that this could be a normal wear part. or is it?should it all mesh together tightly?
 
1/4 inch is not bad mine had almost an inch. no way that i know of to get rid of the play. buy a new key maybe but even then sometimes the play is in the shafts keyway cutout.
 
Yes normal wear! My fix is to get some jv weld clean the slot in the jackshaft and the keyway and glue the worn side of the keyway to the jackshaft.Clamp it down with a vise or grips so you know it is seated and smooth the weld around the area.Allow to dry and away you go.
