eading of FO-20, indicates 0.395-0.397 inch for draft & 0.448-0.450 inch for Position ctrl. If I recall correctly, the exact surface measured to or reference is somewhat of a question, because of the retainer plate.(quoted from post at 14:18:19 05/01/13) Showcrop suggested that I check this forum for specs related to a Ford special tool NCA-502 used to adjust the control valve on the lift cover for a 1955 Ford 641. If someone knows the specs on the gauge I"ll make a few.
I have them all if anyone would like pictures and measurements.
(quoted from post at 20:38:28 05/01/13) I have them all if anyone would like pictures and measurements.I think I have all the Ford tractor tools from the N's through the 10 series,including 2 clutch fixtures and the 8N govenor fixture and some SOS tools. Many I have never used.I got them all when New Holland yanked the local dealership and the owner happened to be my friend.
was speaking of dimension regarding the two 503 tools. I see that you have the HC-100 for setting the 8N control rod position as well.....a rare critter! I can't read the word after 'finished' and before 'indicates'???(quoted from post at 13:13:35 05/03/13) Actually there are 3 fixtures- NCA-503 -N-503 and a HG 101. Take your pick.
(quoted from post at 18:31:34 05/02/13) Finally got around to hunting the guage and making a quick sketch.I also have a SW-508-A for the later tractors.I have all the tools that Dean mentioned but do not relly know how to get any accurate measurements on them. Any questions, just ask.
ou are absolutely correct! I shouldn't post so late at night! Get my "ups" & "downs" all mixed up!(quoted from post at 09:13:11 05/04/13) JMOR the 503 fixtures are exactly opposite of what you are thinking,if you clamp them down flat,the hole is down,not up,plus the distance from the top bolt hole to the center of the pin hole is critical, and the offset to the right is different on both.

Thanks welding man! That's exactly what I needed. The 502 tool will be very easy to reproduce. The 503 and the 503-B is a different animal. Thanks again!

(quoted from post at 22:09:54 04/11/22) I know this is an old subject but would like to find the SW-508A Tool or a suggested alternative to use something else.
hich Dexta model?(quoted from post at 13:34:23 04/18/22) Well, I'm lost, don't know what to measure and what to measure with! Hate to show my ignorance but is there someone out there that could explain in simple terms what is to be measured. A sketch showing where to measure from and to would be great. Next, guess I'll have to find someone that can come do it for me.
K, so I got mixed on what tractor you have. However, the Ford 3000 and Dexta are similar enough in this area that these two images should help you in where to apply the slip gauge (0.390 and 0.450) and what is being adjusted at that point of measurement.(quoted from post at 13:34:23 04/18/22) Well, I'm lost, don't know what to measure and what to measure with!
