First check to insure that your mainshaft has not slipped down a bit. If it has, you will find that the head will move up and down slightly by pulling up and pushing down on the head while on the bench.

If the play is the result of wear, then you can get a better mesh by installing 5m x 7m x 0.5mm spacers between the front bearing in the front transmission housing and the tail drive gear.
