To "Roadmarks", Thank you for your assistance, I am sure everyone who reads the entire post will appreciate it.
As I originally posted, the subject was "Modified nv4500". This referse to the elimination of the hydrolic throwout bearing.
1, boring out the hole in the bell housing would severly effect the structural integrity of the casting.
2, The throw out bearing/torque tube bolts to the input shaft bearing retainer. Trying to turn this down enough to fit in the hole in the bell housing would, in effect, remove the area where the bolts hold the bearing retainer to the transmission housing.
3, Due to the design of the bearing retainer/torque tube, the input shaft tip to case is longer, ie, the input shaft would have to be shortened if the bell housing was mounted directly to the case. Additionally, I personally would not want to drill into a transmission case blindly.
Hope this helps clarify the post.
