REFLECTOR: Lord Mounts

[Terry Miles]

Dave, Steve,

 

In another note, Steve Korney said I should have castle nuts and cotter pins
on the engine mounts.  I think I would have used what came in the Velo
engine kit, and I have metal locking nuts on these bolts.  I am checking
with the factory on that today.

 

My question is about torque setting now.  Would it be 38 ft lbs with the
metal lock nuts or with castle nuts?  Would the different hardware change
the torque value?  Thank you both for this input.  I want to learn, and I
appreciate your help to me.

 

Terry

When it comes to engine mounts I have always torque the 7/16" bolts to 38ft
lbs and have had very good success with them.  It looks like your mount bolt
is not torque correctly.  But may be just fine.  Just torque them to 38lbs
and they should be OK. Make sure you bolts are not bottomed out.  Like being
to long.  Also that the spacer is also installed. 

 

Remember also that most rubber products get harder with age.  In the
environment that our engines run in I wouldn't keep them more then eight
years.  Even less it they start cracking.  

 

Believe me there is a difference between manufactures of mounts as well.
You get what you pay for. 

 

Also keep solvents and oils away from them and keep them clean.  The harder
they get the less effective they are and so being more damage is done to the
rest of the plane. Don't take rubber mounts lightly. They do a lot more then
just hold the engine in place.
