Assembly
· Bare the end of the black wire that comes out near the #3 hole and solder it to the new Mount Spring (Pentax 27230-A105). As it is steel, be sure to use acid core solder NOT resin cored as you will not be able to solder.
· Screw the focus mode selection switch back on using the shortened screw.
· Using a cotton bud, apply a film of thin oil (household or sewing machine oil) to the body mount ring where it may come into contact with epoxy. The same goes for the threads of any screws (unless you want them stuck in permanently!).
· Position the Mount Spring and then the Mount Ring on the mirror box. For the holes that were damaged significantly and were not very deep (ie. there wasn’t much thread engagement even after drilling and tapping) – in this case hole numbers 2 & 5, I used a small amount of epoxy as a ‘filler’. I used a very fine flat blade screwdriver to place the epoxy into the holes. Then screw the appropriate length screws into their holes.
· After an appropriate time to allow the epoxy to set, remove the screws and gently rmove the Mount Ring to check the repair
(see photo. This shot shows #5 hole repaired with the new Mount Spring pin/locator above it.)
On reassembly and with some test shots, the repaired K-5IIs focusses and performs fine.
