NOTE: Please see if you can remove your old diaphragm first before you order. Watch the video and get slide in the condition shown here.
After removal of plastic ring and old rubber diaphragm, this shows what you should have after sanding, ready for gluing on the replacement diaphragm. The old plastic ring can be removed with an abrasive cut-off wheel in a Dremel or high speed die grinder if you use great care and have a steady hand. You might also try an electric hot knife to cut the plastic ring. We offer a video to show how we did it the first time we tried if you click HERE.
Dry-fit the diaphragm first to see how it will fit before you use any Cyanoacrylate "Super Glue". Be sure to only use fresh glue, as old glue may look fine, but will not hold well. Gel type glue can also be used, but use all glues very sparingly as the solvents can affect the rubber. Be very careful not to get glue on the plastic part where you don't want it.
