Hi Carl,
I have in front of me some bumph from Warp Drive Inc. in which they state
that the 1/4" bolts have a setting of 100 to 120 inch pounds (9-10 foot
pounds) and the 5/16th bolts 175 inch pounds (14.5 ft. lbs).
This sheet deals with the hub assembly and It goes on to say that the bolts
should be re-torqued after 1hr operation and thereafter every 5 - 10 hours
as part of regular maintenance. It also,usefully, states that the airfoils
should face in the same direction. If you have a fax I can send this sheet
through to you.
Hope this helps.
Peter

Subject: Europa-List: Prop torque settings
Since we are on the subject of prop bolt settings, does anyone know what the
torque settings for the standard warp drive prop (Rotax 912 engine).
Could also do with the torque settings for the prop hub bolts (these are
something like M6 but probably imperial)
I am currently using 20nm for the main prop attachment bolts but I suspect
this is way too high. None of my manuals gives a figure for the prop bolts
but 20 nm seems to be the setting for most of the other M8 bolts used by
Rotax.
