Sony DSC-F828 loose lens turret - part 7

In this part we will inspect and repair the lens turret swivel mount.

Step 1:
Observe the detent mechanism and the three screws holding the retaining plate on the swivel.  If these screws have come loose then this may be the cause of your problem. Tighten each screw in small amount sequentially in order to apply even pressure to the swivel. The swivel should not be loose, and the amount of tension applied should be enough to require firm pressure to rotate the lens turret. Warning - ensure the plate is only tightened with the spring loaded detent in the slot provided, otherwise the detent will be trapped under the retaining plate and become distorted when you try to tighten the screws.

Step 2:
If the swivel retaining plate screws are not the cause of the problem, then remove the screws and the retaining plate and set safety to one side.

Step 3:
Carefully lift the washer out of the swivel mount bearing slot. Note the part has a grease lubricant. Be careful to not contaminate the grease or the bearing slot, or introduce grease by contact with other parts of the camera. With the washer out of the way, four screws will be revealed. These must be nipped down very tight and held in place with Lock Ace or similar.

This should now have addressed every possible cause for having a loose lens turret. In the next part we will quickly review the reassembly.

  1. When I got to this point is when it went downhill for me. Those three screws that hold the retaining plate on were already locktited in, and I could not get them loose. How did you break them free, or were they already loose when you got to them?
