Its the amount of movement between mating teeth that is free play. There has to be some free play there but there is a maximum amount allowed.

You may be best to get your guy to crack it open and see if its something not helping like a collapsed bearing. It may be possible to get it re-shimmed to improve the backlash problem out but it depends if its wear or damage. He should be able to tell by cracking it open.
