Sota Sapphire Question

Hello I have a version II with an issue. First the four bolts on the bottom edges how much doe those have to come out to release the suspension? I have released the platter screws.

Second, even without the bolts loosened I tried to see if the motor would spin. I turned the table on and nothing from the motor. I did check to see if the belt was around the motor cog and it was.

Do you think I have a bad motor? Or is the suspension bolts effecting the motor?

Any other ideas? How hard is it to replace a motor?

Thanks

Ken
