Binocular Rubber Eyecup Replacement

• Replacement Eyecups For Binoculars

I have a nice Nikon binocular that still have excellent optics and lens coatings. I purchased them the early '70's. However, over the decades, the rubber eye cups have eroded as shown in the attached picture. Does anyone know of a place I can purchase replacement eye cups. I sent an email to Nikon but never got a reply. Genuine Canon replacement left rubber eye cup for the 10×30 IS binoculars. Made by Canon Japan. Add to Wishlist Compare $ 16.28. Canon YA7-0662 Right Eyecup. Genuine Canon replacement right rubber eye cup for the 10×30 IS binoculars. Genuine Canon replacement left rubber eye cup for the 8X25 IS binoculars.

You’re good to go.The only issue now is that the new eye cup is considerably looser than the old one; it slides a bit too easily between the extended and the retracted positions. It’s not a big deal, but if you have any ideas how I can fix that, I’d love to hear it in the comments section below. EDIT Feb 2014: see Don’s comment below. There is a very small ball bearing that fits into a fairly obvious spot on the inside of the ring. It would be very easy to lose this piece in the process, which I did.Good luck. Thanks for the instructions.

My eye cup with the ball bearing poped off and I was lucky enough to retrieve it. It is tiny and re-installing it most difficult.

After several attempts the way that worked was to place the bearing in the circular indentation on the lens holder which you have placed in a level position with the indentation up. Then slip the cap on lining up the notched grove in the eye cup with the bearing which provides 3 clicks of adjustment by notches in the inside grove of the cup.
