The image BELOW is the OLD Shutter Side Grip that I HOPE to also replace in about 2-3 weeks. Takes about that long to get the part.
PART II ( This is the replacement of the SHUTTER BUTTON GRIP)
After doing the repair I described above, the camera looked weird, one half brand new, the other worn... so I opted to purchase the grip on the shutter button.
Here is the step by step of what I did....
Camera BEFORE and the "tools" needed....
Note, I am now using ZIPPO Lighter Fluid as Peter suggested. Worked like a charm removing old two sided tape gunk. See below.
First step, the FILM BACK has to be removed before you do anything. BE VERY CAREFUL as you now have the shutter mechanism exposed and you could easily damage it absentmindedly!! CAUTION HERE until you put it back on.
The next step requires a little care with the SCREWS. You have to remove a holding plate to get the grip off and to then secure the new grip after you put it back on. BE VERY CAREFUL WITH THE TINY SCREWS!! I dropped one and couldn't find it for a minute and almost had a heart attack! Good luck getting another one! Handle these with EXTREME CARE!
This is what it looks like when you peel the old grip off. All the two sided tape remains stuck on the camera body and has to be removed. I used Q-TIPS and ZIPPO Lighter Fluid to remove it.
With the ZIPPO Lighter Fluid, the glue and goop comes off very easy and looks brand new when you are done!
Peel the TAPE off the back of the new grip and start with the edge that goes under the bar you removed. Be careful to line up the grip so it fits properly at this end, and it will simply roll into place with a little bending as you come around the shutter button grip.
Press it in securely, especially around the edges and you are done. My brand new looking Nikon F100. Cost.... $30 total.
SPECIAL THANKS to PN member Peter L! Your patience having me over at your house to watch you change the seals on a Nikon camera and your guidance here was a huge help. This job went smooth as silk. Greatly appreciated.
