'How to' Fit a Classic Mini Rubber Diaphragm

'How to' Fit a Classic Mini Rubber Diaphragm

Replacing your Mini rubber base diaphragm really is the simplest of simple jobs!

All you need is a strong hook (can be proprietary or homemade) or when using stronger wire diaphragms with springs,a pair of pliers will do the trick.

Step 1) - Remove hooks from packaging and feed into the diaphragm as appropriate.

Step 2) - Hang the diaphragm in the frame using the wire hooks - starting at the back/top.

Step 3) - Pull the font wire hooks into position on the frame - slight tension will be felt.

Step 4) - Work around the sides slowly. The diaphragm will be flexible but taut in the frame, awaiting new foams and covers to completely refurbish!

    Hello from the deep south in convictralia. I have to replace the seat diaphragm in my 1965 Cooper S. The seat and vinyl are nearly perfect so I need to know if it possible to replace the diaphragm without removing the foam and vinyl?
    Is there a special tool that might help?
    Thanks Dave D
