Sansui SC1110 replacing main belt
I have to replace the rubber belts (totaly 4 belts) in my old Sansui SC1110 deck. The replacing of 3 belts is finished already (and was easy), my problem is the replacing of the main belt now. I have seen that there is a plastic screw on the backside of the flywheel. Unfortunately I can't back out this screw otherwise it would be possible to slip the belt between the flywheel and the metal plate I think.
Any ideas how to solve the problem?
