Fixed or constant speed, what brand prop? Seems like my Hartzell came

with instructions on torque, but maybe it was in the Lycoming overhaul

manual as well.

My instruction manual said 60-65 ft-lb, clean and dry.  They put  

emphasis on the threads being dry, not lubricated.  If the threads  

are lubricated the proper torque would be lower, but I don't know how  

low.  This was for an Aerocomposites prop on an IO-540, but I believe  

the hubs and bolts are the same for all Lycomings with constant-speed  

props.

If you accidentally get some oil or grease in the threads you can wash it

out with a bit of MEK.

You know, sometimes these planes start to get complacated. Way too many details to keep track of for an old man.

Don,

 I0360 and O320 share the same prop.

 Assuming yours to be 3/8" bolt diameter, the torque is 24 to 25 lbf.ft.  

 Bolts must be dry, non lubricated.

 Got this piece of info from Sensenich themselves.

 Cheers,

Please double check this.  They usuallly do not share the same  prop.  Among other things, the bolt hole diameter in the O and IO-360's is  usually larger.

Jim,

 You are absolutely right!

 What I checked was 0320-150 hp and 0320-160hp (high compression)! Those two use the same prop.

 Maybe I got sidetracked by 160hp and 0360!

 I am sorry I fed the list a mistaken info and charged Sensenich for it!

 Must be one of those senior moments...

 Hope no damage was done.

None here.  I have more and more of those  senior moments myself.  Good to know I don't have a monopoly on  it.
