Why does my Flexplate keeps breaking?
Why does my Flexplate keeps breaking?
The following causes for cracked flexplate failures: 1) Out of balance engine or torque converter. 2) Bad starter drive can cause teeth or ring gear to wear rapidly or break off. Teeth can also break when engine is running and starter is engaged. 4) Some applications may require starter shims to be used.
What causes a flywheel to crack numerous times?
The most likely cause is a missing bushing in the back of the crankshaft. If the converter nose is smaller then the crankshaft pilot area, then the converter will not be centered and the flex plate is what assorbs the stress. Eventually the flex plate will crack. I have also seen…
How long does it take for a flexplate to crack?
More severe misalignment can break a flexplate in 15,000 to 30,000 miles. Excessive crankshaft flange run-out or end plate can also cause flexplate cracking. This may occur in worn engines or engine that have been poorly rebuilt. An engine, transmission or torque converter that has been dropped may also have damage that will cause misalignment.
What causes the flexplate of an engine to crack?
Excessive crankshaft flange run-out or end plate can also cause flexplate cracking. This may occur in worn engines or engine that have been poorly rebuilt. An engine, transmission or torque converter that has been dropped may also have damage that will cause misalignment. When a running engine ingest water or coolant, the crankshaft may be bent.
Where does the flexplate go on an automatic transmission?
The flexplate takes the place of the flywheel on automatic transmission vehicles. It bolts to the end of the crankshaft and attaches to the torque converter. There is also a large gear attached, used by the starter to crank the engine.
The most likely cause is a missing bushing in the back of the crankshaft. If the converter nose is smaller then the crankshaft pilot area, then the converter will not be centered and the flex plate is what assorbs the stress. Eventually the flex plate will crack. I have also seen…
What happens if you have a cracked flex plate?
If the alignment dowel pins are missing, the tremendous amount of torque placed on the components can and will cause a shift in the alignment of the engine and transmission. This can distort, twist, and eventually brake the flex plate; cracked flex plate.
Why is the flexplate on my van cracked?
Flexplate broke after I had the van for 20k miles. I bought “made in mexico” from Napa (the stamping to form it actually left die marks on the flexplate that were very suspicious of weakness. guess what,) then happened again after 7k miles of hard driving. This is the third van with cracked flexplate.
