If you want to put 24" loop style rims on your NAA, 600, 800, 601, 801, 4-cyl 2000, or 4-cyl 4000, Here's what you do. You find a set of C5NN1036H cast iron wheel centers off a 3000-series industrial from the mid sixties to the mid seventies. Make sure you get the lug nuts as they are special. More on that later. The dimensions are as follows: total depth of dish- 2-3/4", total diameter- 21-5/8", loop bolt circle- 6 on 20-1/4", loop bolt hole diameter- 5/8", lug bolt circle 8 on 6", lug bolt hole diameter 1" with a taper, center hole diameter- 4-1/4". The special lug nuts are for 5/8-18 threads and have a taper plus a shank that fills in the gap between the 5/8-18 threads and the 1" diameter lug holes in the wheel centers. The centers will clear the drums on NAA, 600, 800, 601, 801, 4-cyl 2000, or 4-cyl 4000, and of course most 3-cylinder industrial tractors. Take a drum with you when you go looking. Again, make sure you get the special lug nuts!
