I have a rebuilt 8BA flathead with a three speed toploader. The flywheel was resurfaced and new clutch, pilot and throwout bearing. Bad clutch chatter. After driving for a short time with no change I removed the clutch and flywheel. The flywheel had chatter marks on one third to one half of one side. At this point I thought the clutch may be bad (Chinese) and the used flywheel had too many divets from ballancing. So I bought a new flywheel and clutch pressure plate. After installing and driving a short time I still have the chatter. When I removed the Flywheel and clutch a second time, the new flywheel had the same chatter marks on one third to one half of the flywheel as before. Could this be from the bellhousing being out of alignment?
If the chatter marks keep showing up on just one half of more than one flywheel, I'd suspect a crank flange out of true or burrs keeping it from seating properly.
Seems like that could certainly cause that. I would say that maybe the flywheel was ground crooked but, since you put a new one on, that probably wasn't the problem. Could the flywheel not be seated fully against the crank flange or, the crank flange be bent(hopefully not)?? Ron. Oops, landseaandair beat me to the punch
I have this same problem with my truck ever since installing the T-5.....have narrowed it down to the cheaply made chinese clutch disk.
Thanks for the suggestions. I plan on checking the crankshaft flange and the bellhousing and trans housing. Any other suggestions?
