#3909 handle spring: Where does it go, and to do what? Picture?
My January, 1925 parts book doesn't list a part number 3909. There are only four parts listed in the Starting Crank section:
3905 Starting Crank Pin 1909-1925
3906 Starting Crank Ratchet 1909-1925
3908 Starting Crank Spring 1909-1925
3910 Starting Crank Assembly 1909-1925
The 3908 spring is the one with the bent-down end that fits into the hole in the starting crank.
Hope this helps.
From the 8-5-28 parts book:
It's listed in the dealers' catalogues, but before I decide whether I want it I need to know whether I need it.
Interesting! I hope someone in the know will explain, now it's got me curious.
Apparently my 1925 parts book was later deemed to be incomplete and Ford published a more complete version in later years, I need to get one of the later ones like yours.
Inside the handle on the early crank, Bob
From past threads in this forum it seems that the 3909 spring is for 1915-22 cranks that have a small spring on the handle pin to keep the handle from rattling. Note that is does say HANDLE spring. I found no photos of it in place.
Mark, I think all the parts books are included with Bruce's encyclopedia on disk.
As Robert said. Early crank spools were spring loaded.
Steve, did it turn out that your 1915 runabout crank already had a 3909 spring installed, or are you going to have to get one and install it?
No, it's one of the later cranks that doesn't use it. Something else to watch for at swap meets. Installing the #3908 took a little detective work. I had to look at another crank to learn where the hole was.
Just for fun, if you cut a slot in the crank sleeve and install a 1/4 20 cap screw in the crank handle you will not need to buy a leather strap to hold the crank. With the cap screw installed the spring will pull the handle out farther in front and the crank handle will remain upright. The leather strap are about $20 and the cap screw costs 25 cents.
The web site will only let me post one picture today so I will show the crank in position on my next post.
Here is what the crank looks like when you install that 25 cent cap screw.
Frank - So you're saying that a screw keeps your crank up, huh?
