Camera body 503CW | Auxillary shutter & Mirror |
Remount the mirror frame and the upper shutter flap by holding the frame in position and aligning the upper shutter flap to the bearing holes.
Push in both bearing hubs and centralise the mirror and shutter flap side movement by using shim washers. These come in two thicknesses 0.10 and 0.20 mm (810503) and (810505) respectively.
Tighten up both screws (825661) and secure with safety lacquer.
Fit a washer (810503) on each side of the lower shutter flap shaft and mount in the same way as the upper one.
Check that the shutter flaps and the mirror frame move freely and that the flaps are central to the rear plate inner frame.

Check that the foam plastic dampers (13397) are in place and glued to the rear plate where the flaps meet.
Assemble the lever, spring and spring retainer. Locate the spring so the three items are together.
Connect the three items to the shutter shaft and secure it with pin (811108).

The lower shutter is completed in the same manner but note that a weaker spring is used, (816804).
