Thanks Mikey914 !!! (IMG:style_emoticons/default/beerchug.gif)
--------------------------- Is it me, or are these door lock seals impossible to find? I made a post last week about trying to find some of these fragile rubber seals, so that I could complete the rebuild of my door locks - and it appears NO one makes them (Yet!). Hopefully these photos of one will help someone (Mikey914 ??) make some as Aftermarket brand. This one is a bit dirty, but it is still in very good usable condition. So, they look like this in the door keylock assembly: approximate width is about .177 More to Come..... |

Finally done with these. I decided to look at these as "bushings" rather than seals. The reason these were not rubber was the rubber would "grab" at the two surfaces and would deteriorate in much less time as the torsonial worces would exceed the flexability of the rubber over a very short time. The rubber would also require additional torque to get the full range of motion and the stress on the key would fatigue the metal at a much higher rate than normal usage.
The solution is a bushing. If I were to make several hundred thousand of these. plastic injection molding is a cheap easy way to accomplish this probably at a part cost on .10 per unit (after tooling). Heavy up front tooling investment, but savings returned in the unit cost. The downside - plastic will become brittle and will wear over time, but should last at least 15 years. That was 30+ years ago. Over all, I'm suprised any good examples still exist. The solution I found was to machine an aluminum bushing to the correct dimensions. This took a bit of playing around to get everything just right, but these will outlast you and me. Installation is simular to the OEM part with the exception that you apply a marine grease to the lock mechanism install the bushing, and recoat the outside of the bushing to create a water resistant seal. Below are pictures of the installation and and key fitted in and working normally. I'll be cranking more of these out tomorrow, and will be filling orders this weekend. With that being said, I will also have a new introduction to the product line that I've been working on for the last 4 months. Those with the early cars will be interested in them. I will be unveiling the new product in a thread then. Attached thumbnail(s) |
