REFLECTOR: Engine Mount Connection

[Randy Wharton]

Darrel, How did shimming the engine so it centered in the hole affect the
thrust line of the engine with respect to the plane? I'm certainly not
anywhere near the point in construction that you are, but it would seem that
having the correct thrust line would be more important than centering the
crank in the cowl. The cowl can be modified....

Keith,
 
3 of the 5 bolts that came with the engine install kit were the wrong
length.  Part of this was my own fault because I mounted the engine too low
and I had to make shims under the engine mount pads to "tilt" the engine up
to get the crank centered in the cowling hole.  But I think some of the
bolts would have been too long anyway.

Bob,
 
What you said is subject to misinterpretation.  There are also significant
triax buildups on the non-engine side of the firewall as well, which extend
onto the fuselage.  These add a lot of the strength of the engine
mount-to-fuselage joint.
 
When I went to bolt my mount to the firewall, I found that the bolts that
came with the kit for this purpose are considerably (more than 1/4 inch) too
long.  It makes me wonder if I have left something out!  Has anyone else had
to get shorter bolts for the mount-to-firewall connection?

On my XL the hardpoints are built up of Triax on the engine side of the
firewall. There are no "hardpoints" included in the kit, they are built of
Triax. One is top center and the others are spaced to fit the mount. Each
are several plies of glass (Three I think) about 4"x4" applied directly to
the firewall.
 
The IO540 mount fits on the rear of the firewall and the attaching points
are around the sides, near the edges of it.
