Balancing Clutches
Even Ft. Wayne clutches need balancing.
The left clutch is the one I just took out of my car that was put in a couple of years ago when I had my entire engine balanced by the local racing machinist. He balanced the clutch with those dollops of weld on the two flanges, the left one ground off a bit after applying to get it perfectly balanced. The right one is the one I just got new from Ft. Wayne and also needed that washer welded on and some ground off on the opposite side to balance it.

Re: Balancing Clutches
Also had a racing machine shop balance the supposedly balanced rotating assembly from SCAT. The rotating assembly was pretty close but did take some adjustment. They also balanced the flywheel and pressure plate as an assembly; it took maybe half inch of 1/4" rod welded to clutch flange. They indexed the pressure plate to the flywheel so when the clutch disk was added, it went back together with the same alignment between flywheel and pressure plate. The engine is installed and running very well. There is a very slight vibration at idle, which is probably due to the Schneider 248f cam.

You can press some weights (photo below) into the holes above the spring area AND generally you also have the option of drilling directly into those holes down into the spring pads. They usually have fairly large cast-in bosses. (Add) There are balance plugs in both plates you show above already! Thanks, Gary in N.Y. P.S. You also have the option of balancing the flywheel AND the plate as an ass'y. This is "single-plane" balancing and no issues with this method, all the "correction" can be done on the wheel. In the event of changing to another clutch simply rebalance it also as an ass'y. Been doing it this way for over 45 years now. Before balancing as a single unit both components MUST be indexed however!

Re: Balancing Clutches
Is your new pressure plate actually for a tractor (9N, 2N, 8N)? It does not have the counterweights like your old one. It may have stiffer springs to make up for the lack of centrifugal force from the counterweights. How's the left leg?

But, this time, I was just working the transmission and didn't want to go through all of the machinations required to remove the flywheel to balance the new clutch. I actually got quite lucky. My machinist had some old flathead flywheels kicking around that my clutch would attach to. So, he first balanced one of those, then attached my new clutch and balanced that.

My opinion of Ft. Wayne Clutch is diminishing by the mistake. Last time it was the wrong clutch disc with too big of springs that rubbed on the flywheel bolts, this time it's the wrong pressure plate assembly arms.

Re: Balancing Clutches
Did you remove the rear-end completely, along with the driveshaft and transmission to get at the clutch this time around? The reason for asking is that I very well could have the same clutch problem, and my car is also a '47 fordor super deluxe.

Yes, all of that miserable mess.

Here are the instructions from the manual: Of course, you won't be removing the wheel brake stuff from the axle. This thread shows how I disconnect the springs from the axle without a spring spreader: https://www.fordbarn.com/forum/showthread.php?t=98748 While the hangers are disconnected from the axle I usually replace the rubber bushings that are usually pretty warn and need replacement. Likewise for the track bar rubber bushings. Just did all of the above last two nights.

Re: Balancing Clutches
No cent weights on the release fingers is something I sure don't feel comfy about.
If your beautiful FORDOR was mine it would have a 10" clutch with centrifugal weights on the release arms. I sincerely hope all works well for you. Charlie ny |
