after sitting down to think about what went wrong i took a look at the part number for the dmi u joint in my sprint car and the one in my midget and came to find out that there are the same u joint. no my question to anyone out there is how can you have the same size u joint when the torque tube on both cars (sprint and midget) are completely different.
good thing i had no where to go on the track except to stop because the u joint had started to melt from the begining of the splines back which i think is around 1200 degress. talk about possible hot feet
if anyone has had the same problem let me know obviously i wont be running a dmi u-joint in my midget from this point on.
Yeo just had the same thing happen. It started to melt the torque tube and welded the tube to the yoke, 8 laps from new on new engine warm up only
