Guys
Is it possible to install the bottom half of the engine cowl (Vans stock) having
the propeller (standard 2-blade CS) already installed?
If yes, how is it done?
Thanks in advance

I am guessing that you really mean with a 3 bladed prop. AFAIK there is no
issue with a two blade prop, as you just put prop in horizontal position.
With 3 blade you have to modify the cowling to get clearance between the
nose gear leg(cowl bottom) and the prop blades(cowl top), and it still is a
PITA.
With any prop, spinner clearance with front of cowling is a factor that you
have to address when fitting the cowling to allow the cowling to go forward
just enough to clear the baffle seals from the front baffling.

It is indeed a 2-blade Hartzell stock prop.
But I think you already gave the answer I need: I have to rework the front l
ips of the cowl, near the aluminium baffles, to allow bigger clearance.
Is it?

Save yourself all the heartache and pain by cutting off the snorkle and maki
ng it removable. Much easier to fab cowling to aircraft and filter box trans
ition. Makes it WAY easier to remove the cowl. If wanted you could even do a
n oil change and service your fuel injector servo without removing the top o
r bottom cowl halves. If desired, you can now make the lower cowl 2 piece (s
plit down the middle) for simple one person removal/installation.

Method?
Draw the cut line.
Cut through outside with Dremel tool leaving 1/4" tabs / attached sections e
very foot or so.
On inside, scuff the cowl surface / put release on the snorkle surface. I us
ed PVA.
Lay up 3 layers of glass in strips that will become the flange. Let cure.
Drill #40 holes that will become the fastener locations.
On the outside, finish cutting the tabs that were left and pop off your remo
vable snout.
Clean up the edges providing the usual paint gap.
Install your favorite means of attachment. Nutplates work fine.
Enjoy the ease of a two piece lower cowl.

Yes it is a tight fit. Because of the small clearance behind the spinner, you must
keep the cowl near level while you raise it vertically. Working solo I use
a couple of 2x4s, supported by stools, sawhorses, etc., on either side of the
engine, to support the cowl. Then incrementally raise each end. It was still
hard until I did Kellys mod - I cut the cowl to extend the existing nose gear
cutout forward, about 6 inches. This lets you lower the cowl straight down. Not
sure about structural integrity, so I put the cutout piece back in, by epoxying
it to an oversize piece of aluminum, with nutplates around the edge. I attach
it to the cowling with screws. You still may need to carefully trim the rubber
snorkle pieces, the aluminum baffle ramps, etc. Just a note, on my first
test flights some RPM settings gave a strange vibration sound. I determined one
of those aluminum ramps was a 1/16 too long, and could vibrate against the lower
cowl lip. A little filing, noise went away.

With my 3 bladed MT prop, I find the only reasonable way to get the lower cowl
off is to remove the spinner. This gives an extra half inch or so of clearance
to the prop backplate so I can get the cowl on and off. With that said, the
modifications to the lower cowl suggested would seem to make things that much
easier.
