Replaced the tail shaft bushing on my trans and I cannot for the life of me find the torque specs for the long 12mm case bolts. The manuals are strangely absent of this info as is the search on the internet. I can't find a definitive answer.


Thanks,

There are charts for bolt torque specs according to diameter and grade. You should be able to find them. It may not be the end all but it is a starting point.

Maybe a bolt supplier like Best or Hollowchrome would have a chart.

 

Its 12-17 ft pounds.

Also found a complete assemble/disassemble manual online.
