Sony WM-DD series center gear fix

Hej everybody°

One more possibility to fix the klickklack center gear of the sony WM-DD early series (DDII/ DDIII/DC etc.) is to use a cold metal stick. It´s a material based on 2 components Epoxidkitt. You just cut of a piece and knead it for a while and then you have 5 min. to work with it before the stuff get hard like....metal!
You only need a tiny piece to fit in the gap. I made an offprint of the gear in a second piece of Epoxidkitt before and used it to generate the missing pieces in the gap.
The whole story shoudn´t be to thick otherwise the wheel will not move under the arm. I had to grind it on both sides a little bit. Then let it sit for an hour or more and put it back in the unit. Works fine!
The klickklack sound is gone and the rewind function comes back to life! Don´t forget to clean the part before you assemble everything!

Hi Folks


Should we start a request on Facebook and see if we can get some social networking site to help us convince SONY we need these replacement parts?

 

Just a thought and we pay fair money for the defective part clearly but we need their engineering help here?? There are hundreds of thousands of these Walkmans that need this fix


What do you think?

Petitioning Sony will not help there. They will likely have destroyed the molds and the machines responsible for creating the gear with metal insert must be long gone by now. Not to mention that all of the original people who worked on the DD Walkmans have likely moved on to something else or even left the company entirely.
