View Full Version : Is that noise what I think it is conclusion......

Been awhile on this topic hasn't it? Seemed like 11 months ago, lol. We had joy we had fun we had seasons in the sun....oh right...

As many of you know, last December I parked the Lark as it had a heavy clanging noise coming from the back of the engine. It was not knock, or valve tap as I could tune the distributor, carburetor, and the timing and the noise wouldn't disappear. It was suggested that it was flexplate, and on inspection in the inspection hole in the bellhousing, there was a split looking at the edge of the flexplate. This indicated that the flexplate had flexed a little too much, and had split, which necessitated a laborious but necessary repair.

Well this week the car went to one of our reputable chapter shops that specialized in restoration and repair of Studebakers(and had a lift and the necessary equipment, hurrah ]:)]). The flexplate was replaced, the kickdown was adjusted to spec, the front seal in the yoke was replaced(been in there since day one so it needed to get an oxy/acytelene treatment), and had both passenger tranny mounts replaced.

Here was the end result of the old flexplate. I should add this was found through the sound within about the period of a week, so I advise if the sound is found out, that it really shouldn't be shuffled aside :).




The end result, is now I have my daily back for the time being. The Lark has its old get up and go, moreso since its now gotten cold. The sound is gone, with the exception of a little valve tap, and I now have my greater asset in time for the Christmas mall traffic. [8D] :D[:o)]

As Paul Harvey would say, and now you know the rest of the story.........

We talk about that on this forum all the time. However, the pictures speak a lot louder than all of our words. Thanks for the post.

I hope that you checked the centering of the bell housing to the engine as per the shop manual before installing another flex plate. A dial-in will probably prevent the same problem from happening again.

The trans was dialed in, the runout was spot on, and he checked the flexplate after it was bead blasted to assure there was no cracks present. We gave him a couple to use, and one was returned because it had minute cracks and it was unusuable.

I have seen excessive crankshaft end play cause this too, just FWIW...
