Subject: | Mounting The Engine... |
Dear Listers,
I'm getting close to mounting the engine on the 'ol RV-8. I'd like to hold off
riveting the front top skin on until I'm sure all of the wiring and what not
works with the various engine sensors. Is it "safe" to mount the engine before
this skin is in place? Also, I have a QB and I noticed that none of the rivets
along the sides where the cowl hinges go are riveted save for a couple of
temporary pop rivets. Can the engine be mounted before these two areas are completely
riveted?
Thanks!

Hum, hadn't though about actually starting the motor without the skin on. I was
just thinking about whether it would hold the static weight. I guess to test
all the wiring, the engine would really need to be started.
So I guess I'll rephrase my question to "Could the engine be hung AND run without
the top skin and sides riveted?" ...?

Not sure how to respond other than why would you want to do this?
- There should be no wiring issue that cannot be resolved after the plane is
built. If your design does not support this objective, you may want to make
some changes. An easy thing to do is to make the panel fully removable
using Molex plugs. I have never had to do the upside down head under the
panel thing on my 8A.
- All engine temperature senders can be tested with a hot air gun. You can
draw a vacuum for MP. You can run the electric fuel pump to check flow rate
and such.
- Your first engine start essentially starts the timer to your first flight.
You could of course go back and re-pickle the engine for storage but there
is little to gain other scratching the itch to hear the engine (and believe
me this is a very strong itch).
- I would not recommend even fitting the cowl before the top skin is riveted
on. Remember however to take a piece of light aluminum angle across the
baggage door before you cut out the baggage door skin - cleckoing the angle
across what will be the open door area. This prevents the firewall from
flexing when you fit the cowl.
- I suspect you will find riveting of the cowl hinges to be harder after
mounting the engine.

I'm building an RV-8, also, and just hung-the engine a couple of weeks ag
o (IO-360-A1B6).- I don't think it would be good to run the engine withou
t the top skin on.- You need to have that skin in place before you instal
l the cowling.- Van says that you should have all your baffles and cowlin
g in place before running the engine in order to provide adequate cooling t
he the cylinders.=0A=0AI've got the side and top hinges clecoed in place-
around the firewall.- I don't have the top skin on yet, because I still h
ave some work to do underneath.- I wanted to install the baffles next, bu
t realized that the top cowl needs to be in place first.- Then I found th
at the prop needs to be on before the cowl is put on.- I am planning to p
ut the prop on in the next couple of days.- The top skin has to be rivete
d in place before the cowl is installed, because the-clecos will interfer
e - also to get the top of the firewall in the right place to fit the cowli
ng.- So it looks like I'm gonna have to go back to the panel and other st
uff right behind the firewall and get all that finished before I can go bac
k to the engine side.-I hope that hanging the engine will not affect-th
e fit of-the top skin.--=0A=0AA question I have is: how long is it ok
ay to have the engine exposed before it is run?- Also, what should I do t
o the engine before it's ready to run?- I think it might be six months be
fore I crank it up.- It was packed at the factory for long-term storage.
