  • 2N Hand Crank blueprint, dimensions.
  • Does anyone have the blueprint, dimensions of the 2n had crank with spring? Chris posted the other day looking for info on the spring and when I went back to look at his post it was gone. If anyone has this info could you please post it for me. I looked in the archives, in the how to section couldn't find it. Thanks

  • Thank you all for the great info on the crank, much appreciated. Tim, Chris, if you ever get someone to make the spring, I sure would take one or more, please keep us posted. Thanks again gentlemen.

  • I did find one close at MICHIGAN STEEL SPRING CO. but their price is about $40 for one piece, min order 10 pieces, and it is not a LH spiral. I found another one at CENTURY SPRIN0, p/n 289, that would work as well, but not a LH Spiral either and length is 12". You'd get 2-1/2 springs out of that.

  • When I restored our 1941 9N---I fabed the hole in the bumper to use the crank that had always been used with the tractor for the last fifty years. It's a little longer than most and will reach through the bumper and crank the tractor. Kirk-NJ gave me a heads up on how the crank was supposed to be mounted. Will be glad to get the measurements of the crank if you want, Dennis.

  • Make your own
  • My father has a little forge he uses to make springs in his shop for the old guns he works on. That blue print gives all the information needed to make a spring. Make or buy a little forge and a roll of wire and get busy. ;-)

  • Re: 2N Hand Crank blueprint, dimensions.
  • There's a How-To drawing of the hand crank for making your own but it has at least one incorrect dimension on it. The OEM 9N-17040, 2N-17040, and NAA-17040 Ford hand cranks were 11/16" diameter round stock, not 5/8" as shown on this drawing. The lengths shown on the DIY drawing are also wrong. In addition, the wood spinner handle was never on the original 9N or NAA hand crank, only on the 2N unit, and there was never an '8N' model/part. ALL 9N, 2N, and 8Ns used the 9N-17040 hand crank in the parts shipping kits. FWIW: The NAA-17040 hand crank, issued with the NAA Model, was identical to the 9N version except it now had a knuckle on the crank end. It is also important to know that hand cranks will not work if you have a grille guard (bumper) installed. Grille guard/bumpers were never factory installed parts -always dealer optional accessories.

    D-I-Y HAND CRANK -NOTE NOT TO OEM SPECS:

    Chris and I are working on finding a supplier of the spring. The drawing specifies the spring as:

    ID = .75 .010"
    Spring Wire Diameter = .062"
    Free Length = 4.75"
    19 Coils, 17 Free, Closed End, Ground, L.H. Spiral.

    Nobody stocks a standard one, and the LH spiral might have to be dropped in search criteria. I'd speculate that most want a crank for their wartime 2Ns mostly for show anyway. It is possible to get it custom made, and that is what we are waiting on now. As with anything, the more produced, the cost of manufacturing and selling it for will be reduced. That being said, there probably is not a big market for these. Doing the math, with a 3/4" ID and a wire diameter at 1/16" the OD calculates to be 7/8". Since the spring OD does not encroach into the crankshaft nut, the OD is not that critical. However Chris measured the grille access hole and said it is 1" so the spring OD cannot exceed that.

  • The spring is 2N-17042 and is made from oil tempered steel wire Type S (.063 DIA). 19 coils (17 free) with ends closed and ground. 4.75" free length. I.D. = .74/.76 After coiling heat to 600 degrees F for 30 min.

  • Re: 2N Hand Crank blueprint, dimensions.
  • Useful spring information would include wire Diameter and number of Turns... at least turns per inch.
