Installing the Vans engine mount to the Rotax 912ULS

[backcountry]

Looking for the correct torque for the 4 Allen screws that attach the Vans engine mount to the Rotax 912ULS. I’ve seen 30 ft lbs but also 44 ft lbs. Also using Loctite 243.

It’s 44 ft lbs for the 912iS. I’d think the ULS would be the same, but it should be in either the Line or Heavy Maintenance Manual.

It’s also 44 ft-lbs, 60 Nm, for the ULS.
