...new at offering anything on this website.
But as I go through my restoration, I have had to have several things remanufactured, machined, or re-fabricated when they are no longer available. These particular items are not available from any sources that I can find. 1. bearing bracket bushings, (4), used on 914 750 165 10 and 914 750 271 10. 2. 914 750 189 10, bearing sleeve, (4), used on headlight motor push rod. 3. pivot pin, (2), used on push rod, 914 750 185 11, left and right side. ![]() The material used on items 1 & 2 above is a black acetal resin (Delrin), the original was white. The material used on item 3 is bronze. I increased the root diameter of the threaded portion using a .250-28UNF-3A thread instead of a M6 Thread. I also increased the diameter of the thread relief just before the bearing surface that interfaces with the headlight mounting assembly. (When the M6 nut works it way loose, the part fails forward of the bearing surface on the narrow root diameter of the thread, then the headlight assembly imperceptively flops, but most notible, the headlight doesn't sit flush with the curve of the front trunk lid). The vendor cost of item 1, (4) is $ 8.00 a piece, 4*8=$ 32.00. The vendor cost of item 2, (4) is $ 8.00 a piece, 4*8=$ 32.00. The vendor cost of item 3, (2) is $20.00 a piece, 2*20.00= $ 40.00. (considering the size and weight, or lack there of, shipping is included). This is just what I paid for a one off deal. I'm sure the costs will drop with quantities. Anyone can leave me a personal msg or reply to this thread. Dave Estep, (dlestep). |

...the machinist will be in my office tomorrow at 1100 hrs. We will be going over tolerances and kit definition and quantities. I performed a tolerance study on each of the components and found two dimensional changes on the bushings.
The motor side bushing of the push rod needs an additional .00152 split on the ID and OD of the pivot pin bushing on the push rod needs an additional .00325., at least on my push rods. All of the components fit well, but the have 1 degree of play that I want to remove. With the rocking arc movement of the headlight stepper motor, I would like to limit the motion to one plane. I would like some cross data, if anyone has headlight push rods that are out of the car, I would appreciate 5 place decimal reads on the ID, so hopefully, a few reads from someone with a caliper would be good. (thanks in advance). I will be adding washers and .250-28UNF-3B Nylon Insert, Hex Nuts to the kit, for the pivot pin install, so everyone goes out clean. If anyone else wants to jump on this, I am arranging a short run of 10 sets. I will let everyone know, on the list, when they are ready. Now I have to arrange a paypal account or something and get everyone's mailing address. Dave (IMG:style_emoticons/default/type.gif) |
