Torque settings in alloy

[numenius]

I'm rebuilding a Volvo outdrive and have the full Seloc manual, but can find no suggestion as to torque settings when reassembling the actual body sections themselves. Given that they are alloy, you just know the risk of stripping - anyone suggest what might be a suitable setting for this sort of material?
As for what model it is, we've never discovered- the plate is missing and even with the diagrams and serial number no dealers have been able to help - Volvo Penta themselves of course just don't even bother to reply!

Yes great risk of stripping or even cracking the castings - particularly if you use a lubricant in the tapped hole as this can compress the air in the bottom of the hole and split down the side (I did this once in my youth but my mentor soon put me right!)

The settings could be for a 6mm screw as low as 12ft-lbs but don't rely upon that.

might give you info. I use them for other standards so they probably have torque setings if you do a search
