I would like to know what years of distributors it will time, and what the adapter V-126-B is for?. I will need to buy the instructions for it be for I use it. Thanks, Randy. ford38v8 10-03-2009 @ 2:14 PM reply profile send p.m. Senior Posts: 2739 Joined: Oct 2009 Randy, The KRW Timing Fixture instructions begin on page 341 of the (reprint) 1938-1940 Ford V8 Service Bulletins. This is Subject No. 12127 Page 59 of the original Bulletins, dated April 15, 1938. You should note that even then, the instructions begin by saying that the Stroboscope method is preferred to the Timing Fixture. Don't throw it away, though... Sell it to me and I'll use it a wall hanger! Alan 42wagon 10-03-2009 @ 4:23 PM reply profile send p.m. Senior Posts: 584 Joined: Oct 2009 Randy I have a timing fixture although not a KR Wilson. It too has an adapter. I believe the fixture will time all distributors from 32 to 48. However there was a change in 41 from a three bolt mounting to a two bolt mounting. This is what the adapter is for. At least it is in mine.

I still would like to know what the adapter fits?. I have my distributors strobed too. Randy. RSS 10-03-2009 @ 4:46 PM reply profile send p.m. Member Posts: 37 Joined: Oct 2009 Thank you 42wagon. It took me so long to type the last reply that I did not see yours! I was told that the adapter V-126-B was also used on the Lincoln V12, I am wondering if that is right?.

I don't have the adapter but it should be for the later two-bolt distributors. If your instructions in the Service Bulletins are the same as mine, they're not what you need especially if your fixture has a degree scale. Most fixtures with the metal box have scales, but occasionally one shows up without the scale. My Service Bulletin instructions are for the wooden box ones with no scale. Unfortunately, the KR Wilson instructions are not well written even though they show the use of the degree scale. It's really simple but they make it sound complicated. (An A/P should have no trouble.)

I will buy the instructions for it from a parts vender next time I order parts from one of my cars. Randy supereal 10-04-2009 @ 9:22 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 As said above, the distributor machine is the best way to set up a distributor, in any case. The KRW fixture, and others of its kind, serve the purpose of adjusting the points in relationship to the position of the cam. We had one at the Ford garage where I worked, but almost never used it. If you have an ohmmeter, you can set the points just as well using a straight edge. The process is a bit long to quote here, but I can scan it for those who want it. The meter serves the same purpose as the light on the KRW. I've done it, then checked it on our Sun machine, and the results are very close. If you do have a fixture, be sure to accommodate any backlash in the distributor, or the setting will not be accurate. MTLott 10-04-2009 @ 12:12 PM reply profile send p.m. Member Posts: 38 Joined: Oct 2009 For clarification, with just a straight-edge you can only set the initial timing advance. You cannot set the dwell ... as with a KR Wilson fixture. In order to set the dwell you must be able to read the degrees that the points are open/closed ... or guess and set the gaps. The later KR Wilson is designed to do a good job of just that with the added Dwell Scale. The earlier model does OK but is not as versatile. An ohmmeter set on "beep" does work great. Strobe machines obviously have several advantages but one thing that's rarely mentioned is that they can require calibration. With a couple of guys in the country actively doing this work, Sun technicians are a bit hard to find. supereal 10-05-2009 @ 8:47 AM reply profile send p.m. Senior Posts: 6819 Joined: Oct 2009 There is a routine for calibration of the Sun machines, but we keep a known correct distributor to check ours when it appears they need attention. So far, we haven't had to adjust it. We sent a couple of the meters to Bob Masters in Tennessee to be repaired and calibrated. He sells machines and parts. For the KRW fixtures without the degree scale, the pin drops into the hole to signify when the points should open. As for setting dwell on a static machine, good luck, particularly with the poor quality of the repro points out there. One of the most prominent problems is point "bounce", due to weak springs, which only show up as the distributor is turning.
