New bearings

Hey guys I just recently got a yyf shutter and it’s great but after am hour or so of playing, the bearing started to become loud and it became responsive so I put some thick lube on it and the bearing still dosent work. I need help!

You need to clean out that thick lube you put in. A lubed bearing is responsive.

Thick lube will only make it more responsive, clean out again and use thin lube. I use less than drop, you put the lube on the point of a needle and then touch one side of your unshielded bearing. spin it on the point of a pencil with your fingers, re-shield and should be good to go.
