Tech Question
Jayson Fleming, Roseville, MI, 1964 Dodge Dart GT 340
I recently removed this 340 due to lack of power.
During
inspecting I found the thrust face bearing was wiped out so bad that the
crank could travel about .040-.050 endplay. Could a bad convertor or flex
plate cause this kind of damage? The flex plate is a B&M and when placed on
a flat surface has maybe .010 rock when you push on one end. When I removed
the convertor screws the convertor spun freely before the engine was
removed.
Thanks for the help. Jayson
Jayson--
No. The beefy converter shell kind of "straightens" the flex plate when bolted up, and the real torque converter support comes from piloting directly in the crank's rear hub and the trans's front pump bushing.
I suspect too much thrust clearance to begin with. Probably, the crank is trash.
