I had a NOS Anderson timer I wanted install this morning. The first problem I had when I installed the timer shield, it would not let the rotor go on all the way to install the cap pin. I took the shield off and installed the rotor. Next problem the brush cap will not fit over the rotor. The way the rotor is designed it will not let the cap fit over the pin. Has anyone had this problem? You can push the flapper down and put the cap on but then the flapper will not work. Thanks for any help.
Do you have an aftermarket timing gear that is thicker than the original Ford gear, pushing the flapper too far forward?
Or maybe the parts were defective or mismatched when new, causing it to remain unused on a shelf - that's a problem with many NOS parts.. A picture would probably help explain the problem?
First off, repro timer shields can vary in thickness, so you might have that issue.
Second, don't know if your NOS has all its parts, or a mix of Ford? The new Anderson has flapper made with a c-clip instead of rivet on the flapper axle.
Original Anderson flapper
With the c-clip design and the flapper on the new ones, a special cup is needed to retain the pin and fit to the flapper, that cup is notched to clear the flapper flip action.
You might want to get the new repro parts to secure your original flapper, or at least modify the cup by grinding away in that one area.
If you use a modern cam seal, you don't need the shield.
Back when Frank Fenton had the Anderson business, his instructions said to remove the brass shield and felt, and to replace with a modern seal. I haven't gotten one from Hutch, so I don't know whether the instructions still say that.
Also, Frank had a narrower flapper assembly to work with thicker timing gears. I assume Hutch has those as well.
What I do get the modern seal for the cam shaft and don't run a shield.
And leave it alone
Thanks to all and MTFCA, Dan, I did modify the retainer cup, did away with the shield and had already installed a new seal. Everything works fine, the mod on the cup was the problem.
