Fuji GS645S Wide 60: Shutter Hanging Open and Rangefinder Fault

Servicing a Fuji GS645S Wide 60 Professional. The issue was that the shutter would hang open and the rangefinder did not work. On opening the shutter, I noticed that the pallet control pin was quite bent (photo four) and that there were metal shavings on the main cam (photo five). Also, quite a bit of over lubrication with moly lube (some technicians belong to the school of Lubricate Until It Works. I am not one of those). Not good signs. Found that the blade opening ring was sticking. After some troubleshooting, I removed the shutter and found that the mechanism plate was around nine thousandths out of parallel (photos six and seven ) and this would be caused by an impact. Best solution was to replace the shutter mechanism plates and housing. Surprising that the shutter could get so damaged even with the “crash bar” that Fuji provides on the front of the camera.

This particular camera wins the award for most problems found on one camera this week: damaged shutter, damaged rangefinder and fungus in both front and rear lens groups. Shutter housing replaced, rangefinder repaired and both lens elements replaced as the fungus had damaged the glass beyond cleaning.
