quick question,

can a cracked bellhousing break an input shaft? reason i asked is because i slung my driveshaft awhile back and broke the transfer case housing and transfer case adapter, got everything back together and a few days later i snapped the input shaft in the 4l60. the bell housing has a couple ears broke off of the top and a hairline crack on the bottom. didn't think my setup would make enough power to break the input shaft, esspec with a stock converter.

 

The cracks could possibly alow the shaft to be stressed in a manor not intended, The shaft shaft is made to withstand a twisting force not a bending force so yes it is possible .Though there are several other possibilities to it could not be ruled out

 

I would have to agree with post number two about bending force stressing the ntegrity of the input shaft.

 

I would have to agree. This happened to a friend of mine, and we just had to change out his tranny.

 

thanks guys, going to an 80e, that should fix it
