Welding Thrust on Cast Crank?

Some of the reasons you get Thrust bearing wear or failure is due to Converter ballooning . Two things to check ,one is the pull up on the converter and two, the maximum line pressure the transmission makes . If the converter does not have enough pull up and the shell balloons , the converter neck can bottom out on the pump gears and force the crank forward . Also if the converter charge pressure is high , this causes a force at the converter neck , the bigger diameter the neck is the greater the force .
