I believe that the specs were posted here one time in the past but do not have the information at hand.

I would be interested in one if you reproduce them.

Another tool that would be handy and, I believe, necessary for use with the NCA-502 gage is the lift arm positioning fixture (do not have the Nuday number here).

JMOR and others here is a sketch of the NCA-503 1955 and up. The N-503 is for Jub and NAA. I am not a draftsman,I hope you understand the drawing.

Looks good to me! I'm sure all will appreciate it. Any comments on the HC-101 sketch that I posted?

I have never used the HG-101. Most of my work on the N series tractors have been engine, clutch, and transmission related.I have not worked on too many with hydraulic problems.Most of my work is on the Blue Fords 1965 and up 3000 thru TW-5. I have these tools because I bought everything the old Ford dealer had, including the valve grinding equipment and rod bushing hone.

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.

Finding someone with these tools is great as they are becoming so rare. Pictures and measurements of the NCA-502 Gauge and the NCA-503-B Lift Arm Holding Fixture would be extremely helpful. My shop manual shows both of these tools so I know what they look like. I really need the specs so I can make them.

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.

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!

The important dimension for the 503 tool will be the vertical distance from the top cover gasket surface up to the center line of the pin going thru fixture & lift arm.

Actually there are 3 fixtures- NCA-503 -N-503 and a HG 101. Take your pick.

Quoting Removed, click Modern View to seeI 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'???

JMOR, I will try to figure out some way to get you some accurate measurements tomorrow. The writing on the HG 101 says (finished edge indicates center line of ball with an arrow pointing to a hole. The very end has 2 notches, one for draft and one for position.

That HG-101 is really intriguing! As for the other two, if you can clamp the bolted part down to a real flat surface & then measure from that surface up to center line of the hole for lift arm pin, I believe that defines the dimension it was intended to set. Some real neat items to own, for sure!

The HG-101 is probably like the attached sketch (can't see the full part in your picture).

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.
