Be aware, removal of the lSO setting ring is required to enable top cover removal. Unscrew the film rewind knob and remove the circlip.
In addition, there may be extraneous adhesive around the joint of the red stripe part to the top cover/body joint. Careful manipulation should release it.
Ensure no camera controls are displaced as problems will arise during reassembly.
I used this method to replace a broken aperture index ring, it's a bit tricky getting the spring back on, attaching both ends then easing the spring around the pulley, around 60 minutes of work. I also found the glue around the top front of the body a bit tricky too

Doesn't work for the 301, although it looks similar I can't find any way to remove the top or the front case
The F301 and N2000 are identical, so the guide should work. In this guide the top case isn't removed, as the film rewind knob is preventing it from coming off completely, and instead just lifted with the bit of leeway the popped up rewind knob provides.
Is there a way to remove the plasticzek top cover, as comment above says, the knobs prevents me from removing this part. My plastic cover is broken and I want to change it for a new one, is there a way?
The small metal post that was under the ring… where does this go? It moved as I lifted the ring and now for the life of me I can figure out where it’s meant to be… help. I opened it up because the black aperture ring was sticking and not springing back when I moved the aperture dial on the lens. My original problem is fixed but now I can’t reassemble my camera.
The only place I could imagine it fitting is inside the spring, just round from the screw at 2 o’clock… is that right?
