  • Part number KL12174a

    Got home a little early today and decided to take a whack at making a few of those "washers". The piece of scrap I carved them out of was a little thinner than the original part but also seemed to be harder. With more time to look this weekend hopefully I can find a thicker piece to make a few closer to the original.

    The hole is offset slightly to the side away from the timing marks. I think the washer is supposed to be installed so the timing marks are on the side away from the cap clamp like this:

  • nice work Kevin. Your right about the washer placement. Most housing have a mark that lines up with the marks on the washers.

  • If you can't find them, that looks like a part I might have fun making for you. Shop time is quality time, grin.

  • Shouldn't be to hard to make. Don't realy need those timing marks unless you need to advance the timing for a sherman head or some crazy thing LOL.

  • I'll see if I can knock out a few this weekend. Timing marks can be punched before bending the plate/washer. Might even make a few a little longer in the opposite direction than I've been having to file the slot in the distributor body. That slot isn't long enough to accommodate some of the "almost fits" points sold today.

    Seems like the screw was a fairly standard pan head type.

  • Just some friendly machining advice: The timing marks are usually knurled, but I suspect these parts were stamped special after the radius was formed. They were probably stamped out by the thousands on a special stamping machine. If you put the marks on when it is flat, once the piece is bent, the marks will get deformed a bit and not necessarily true anymore. I can't say exactly how much they will deform, maybe not anything to be concerned with. Try a few samples and compare to an original. Like Dan said, not really used much anyway. I tried to use it once and ended up putting right back to where it was set. here's the deal. Somebody makes all of these parts. I don't know if new aftermarket units even have them. They just don't sell them all individually. Same with some carb parts. Kits don't have some of the finer brass jet screws and plugs but they are on new units.

  • Original screw was hex head but I'm not worried about them, should be easy to get from McMaster Carr or some where like that.

  • FWIW, the distributor side timing plate is listed in the MPC's under the distributor parts list. They call it "WASHER" and the part number is 91A-12174. The '91A' prefix denotes it was used on that previous module. There are a few more 9N front mount distributor parts also with that prefix, like the rotor, condenser, coil spring screw, coil gasket, and a few more.

  • The 91A part prefix indicates the part was designed for and used on a 1939 Ford car. The V8 engine distributors of 39,40,and 41 used that little plate. FWIW. SoS.
