I have had the instructions from the Service Bulletins for years in the repro books, but have NEVER been able to see the photos clearly as they are so dark-no detail is visible at all. I am going to be saving images of the documents that you posted. The KR Wilson instructions (for the later V126 with the Dwell Scale are interesting. These show the clip from the V126 connected directly to the contact on the inside of the distributor as opposed to the 2nd generation (earlier than the KR Wilson instructions) instructions from the Service Bulletins that say the coil must be in place (which in practice seems to be the case). The KR Wilson instructions also say not to bother with the feeler gauges because of the dwell scale (which makes perfect sense-in practice there is no need for the feeler gauges with this model V126). Thank you again for posting these! RAK402 12-01-2023 @ 3:31 PM reply profile send p.m. Member Posts: 430 Joined: Jul 2015 Carcheologist I finally found my Service Bulletin book for 1932-1937! Attached is a copy of the page with the KR Wilson Timing Fixture-it looks EXACTLY like yours (with the arm on the side to duplicate the coil contact). It also mentions that the long lines on the disc are the firing points (no mention of "F's"). Interesting to note that, the 1938-1940 books states that the Distributor Stroboscope is the "only fully approved method of timing the Ford V-8 and Lincoln Distributors," but that "a fairly accurate timing of these distributors can be made with the V126 Timing Fixture." The 1932-1937 book states that the V126 "obsoletes all timing instructions previously given. In the future all v-8 engines will be timed by means of this fixture to four degrees initial advance." I am looking through the book for the "instructions previously given." So it appears that, up until the advent of the Distributor Stroboscope, the V126 was the officially approved (by Ford) way to time a Ford V-8 distributor. As I stated early, I am sure the stroboscope, Sun Machine, etc. will yield better results, but it is interesting that early on this was the way to go (officially).

On this page (204), they instruct the user to remove the fiber post that has the contact for the points and replace it with a wire with an clip on the end of it. This because the contact on the post evidently did not exert enough downward force on the Breaker Plate (as the spring on a coil would). If it were mine, I would keep the fiber post as (and I am guessing here) there probably are not many that have not had that post removed.

The interesting thing about the side post with the pin is that the pin is spring loaded and can be adjusted inward to exert pressure on the point plate and then the holding screw is tightened to keep it there. I would think that it would adequately apply the required pressure to simulate the coil, but who knows? I have done 3 or 4 distributors so far and they seem to be responding satisfactorily using the fixture. I really enjoy using it. I'm at least more confident that I'm setting up the distributor timing as close as possible to the stated factory specifications.

So there are at least two of us using these successfully now-OUTSTANDING! https://youtu.be/-n1AThTxfxU?si=OgY-mVi0wxiHfLtR Carcheologist 12-06-2023 @ 7:11 PM reply profile send p.m. New Member Posts: 128 Joined: Jan 2016 Yes sir, thanks for all the photos and supporting information! RAK402 12-06-2023 @ 7:38 PM reply profile send p.m. Member Posts: 430 Joined: Jul 2015 Carcheologist, Could I trouble you (at some point) to post a short video of your V126 in operation with a timed distributor on it? One thing I have noticed, when the distributor is correctly timed, the point where the light first goes on (when the dwell is set correctly) is when the Firing Line on the disc is aligned with the left edge of the projection that supports the timing pin. This gives the precise 35 degrees of dwell that Ford recommended. Also, below is a video from 3rd Gen Automotive showing the timing of one of these distributors on a Sun Machine. What is very interesting is toward the end of the video, where he checks the timing on a KR Wilson V126. He then adjusts the timing based on the V126 results (correcting the Sun Machine results). He does mention that only the Sun Machine will test the advance and test the points for float. https://youtu.be/a1HktSGhBho?si=941e90YcUO384yjD This message was edited by RAK402 on 12-6-23 @ 7:41 PM Carcheologist 12-07-2023 @ 7:41 AM reply profile send p.m. New Member Posts: 128 Joined: Jan 2016 RAK402, I'll try to post a video in the next day or so. Thanks for your patience.

I don't understand that since it's only 32 seconds long. Anyway, I am able to text it to you if you like.
