Apparently static sitting has very little impact on the mounts, which in my case are Lords, it's the flying loads that have the effect, heat and torque loads etc. My local AP (approved person) has said to me that it's much better visually to have the spinner sitting high in relation to the top cowl than the other way around, but as has been said even after some time flying, if you need to "pick up-even out " the set of the spinner to cowls the mounts themselves can be packed with spacers. It's way above my pay scale as well to work any formula for that one, it just goes to show its an art not a science.

That just gave me another .025" gap at the top rear and lowered the front another 1/16". I ended up with top of cowl 3/16" lower. I had engine hanging very little before fitting cowl. The relative position has not changed, but the cowl hinge eyelets do wear hence the black streaks found after flying occasionally. So I think my cowl has dropped slightly in 88 hours and engine has sagged the same. If everyones stock cowl fits like mine the bottom sticks out below. If I was doing it over, I would keep top rear cowl gap tight with no clearance during fitting. I also would provide 1/4" clearance between spinner back plate and fwd cowl to make removal easier. 1/8" is just too close. I would also cut slot for nose gear leg fairing 2" deeper with removaable piece/nutplates. -------- Wayne Gillispie Read this topic online here: http://forums.matronics.com/viewtopic.php?p=386043#386043 ________________________________ Message 3 _____________________________________ Time: 03:54:06 PM PST US Subject: Re: RV10-List: Re: Engine Mount Slump From: Rob Kochman +1 on the spinner/cowl clearance and the larger slot for the gear leg. I did the latter before paint, but the spinner/cowl gap would have been too much work to fix. -Rob On Fri, Oct 26, 2012 at 8:37 AM, rv10flyer wrote: > > Van's instructions say after all of the fitting to install the smaller > diameter pins in the top rear hinges.
