offline_mail,
In your video I am unable to hear the "5th. click". Might be gummed up payout slides or 5th click lever.
Play the machine and pay attention to the following:
Pull the handle when reels are kicked (kicking noise) = 1st. click.
1st. reel stops (sound) = 2nd. click.
2nd. reel stops (sound) = 3rd. click.
3rd. reel stop (sound) = 4th. click.
Payout slides reset (sound) = 5th. click.
You can search this site for "5th. click" and you will find some posts to resolve that issue. Also, when doing any service on the machine Do Not Use WD-40.
