hey guys i need the tailshaft or housing torque specs for the bolts that hold it to the case. thanks

 

Should be around 40-45 ft-lbs

 

ok thanks, i have that at 30 now so u will give it a little more to 40

 

I know this is an old Post but I can't have misinformation out there the tail housing to main body is 23ft.lbs

 

M10 x 1.50 steel bolts into alum. die castings will be fine at 23lb-ft or 40lb-ft. I go 30. On an application where you're assembling, then shimming bearings and reassembling, just keep your torque consistent throughout the build.

 

I usually Heli-Coil em and use the torque appropriate to that size hardware (10mm)... which as stated above is in the 40 - 45 ft-lb range.

 

Borg Warner and tremec both say 23-25 ft.lbs otherwise you'll push out all the sealant

 

You can't accomplish that at double any of the torque measurements mentioned in this thread. The (relatively) rough machined surfaces of the main case and extension housing allow for RTV to fill in small gaps. And the torque levels I'm referencing are not able to compress an aluminum case surface sufficient to prevent that from happening.

Aluminum has a different coefficient of expansion than steel. A case that will expand and contract a bit with heating and cooling needs a conservative clamping force; nothing more. In the case of the T5, the case assembly is more than adequately retained with the bolts. What you would accomplish were you to grossly overtorque the extension housing bolts is stripping thread, or cracking case castings.
