I can't see how he could machine the bell housing?? If the bell face gets cut it will no longer be square with the trans internal center line?? If the problem is with the block,...... cutting the bell will solve nothing. Treblig
Exactly, if the problem is in the block machining, then you have to fix the block...
Altering the bell housing to accommodate the block will just throw off other things...
On the block line that I worked on, they had cast datums inside the outer cup plugs that our details would use to find the center of the casting, then we would machine datum holes on the oil pan surface... After that the machined datum holes were used for locating the block for all other details... Machining is more accurate than castings as there is more variation in castings that machining..
The first thing that we checked when something was off was the cast datums to the machine datum holes to make sure that they were correct... You should figure out where the machine datum holes are and measure from them to find if/where the problem is...
