95 to 115 ft lbs IIRC, I don't have a manual at the present, so someone else please verify-

This has been discussed before on one of the BBs and I think the answer was that this is the pre-torque before turning the fastener xx degrees to achieve final torque.

In the Allsion manual that I had, it just had the torque setting for the bolts. It wasnt a two step process.

My manual says 96-115 ft.lbs.

This is for an HT 748, but should be the same.
