View Full Version : The engine is finally back!

December 21st 05, 03:43 AM
After sending my Lycoming AEIO-540 to the factory for a mandatory repair it
has finally returned. At Oshkosh this year the people at the Lycoming booth
swore it would take only two weeks, but when the actual paperwork arrived
everything said one month in the shop. It ended up taking a little over a
month, from the day it was crated by my mechanic to the day it was returned.

Lycoming says they will pay for the costs of removing and remounting the
engine, along with the shipping as well as the repairs. Mine only had a
little over 300TT. I guess they figure the costs of the new crankshafts as
well as the repairs for all of the engines would be a lot cheaper than
series of very expensive product liability lawsuits!

Anyway, it looks like it'll need mineral oil for a while, and then there's
also the risk of something else working loose or breaking after the removal
and install- we'll have to wait and see in this regard. I may take it and
run it hard for a few hours, and then take it back to the mechanic to pull
the cowling and make sure everything stayed tight.

I've heard a lot of different advice on breaking in a new engine- run at
full power, don't run at any power for a long period of time, vary the power
settings (MP and prop), etc. Any advice? When do you switch back to regular
detergent oil?

Lycoming should have sent a copy of their recommended procedure with
the engine. If not, I'd get on them to give you a set of guidelines so
that if there is a failure during the breakin period they can't tell
you that you used the incorrect procedure.

As others have said, follow the Lycoming recommendations to the letter.
It will involve high power settings until the rings seat (assuming you
have new rings) and you will use mineral oil until that happens. The
event will declare itself with lower CHT and reduced oil consumption.

I did my first 30 minutes orbiting the airport with tower permission.

Glad you got it back! Hopefully it will be a smooth install and no future
problems.

Google "Lycoming engine break in " and you'll get several hits directly from
Lycoming's site regarding break in. If there is any warranty remaining, I
would call Lycoming and ask them directly, then document the call and their
advise. (just in case) :)

Congrats. Glad you got it back.

I'll echo that... we did an overhaul by a local shop. Piper Pawnee
O-540-235HP with STC to 250HP

He did his normal run at the shop.. then once installed.. it was a quick
(short) static run (mag check) to check oil pressures and leaks.. then shut
down inspect...

Then it was start and go.. no ground time.. it was 100F out and we did not
want to overheat on the ground... FULL Power climb to 10,000MSL where the
outside temps were cooler and we could run it full throttle at cruise.
Stayed there for 1+30 monitoring oil temp and pressure (no CHT available).

A few more flights at altitude to accumulate about 5 hours total before
putting it to work, glider tow.

Over 55 hours on the engine now and just swapped from Mineral to regular AD.
All appears well.

Before starting the last engine I put together, I borrowed a oil pressure
pot to fill the galleys.
Attached at the oil pressure takeoff and pushed oil in by air pressure
before the first start.
Used a quart or so. It not only fills the galleys but also pumps up the
lifters.
Engine fired on the 2 blade and ran smooth!

I did something similar when I replaced the engine in a van I owned long ago. I
scavenged an empty freon tank, removed the valve, and poured four quarts of oil
into it with a funnel (seemed to take forever). Then I put the valve back in and
hooked it up to an air compressor. Once I got it pressurized, I turned it upside
down, hooked it up to the hole for the oil pressure sending unit, and opened the
valve.

Coffee is only a way of stealing time that should by rights belong to

I don't know that he was lied to. You got to figure it took a week to get
from him to them and then a week from them to him. That means the work took
2 weeks.

BT,
Can I ask how much the OH cost at your local shop? I'm always interested
for when the day comes we'll have to OH one of ours.
Thanks

When I was member of a local club full of old pilots, they had a cilinder
crack on a 0-300 form a C172B. They pulled the cilinders, topped it and
then proceeded to 'break it in' by insisting on reduced power for the next
100hours...

I quit that club and joined another.

They actually told me two weeks total- from the day it was shipped to the
day it was returned.

I'd have to check with the treasurer... but I think the shop price came
close to $19K.. plus we did out own "in house" labor for the R&R, plus new
braided oil lines..

Well they were idiots for saying that and you have every right to be ****ed.
I assume you or they didn't ship the engine one or two day air. They really
should quote "time in the shop". It's not like they can control how long it
takes to ship.

Well, glad to hear it's still doing OK, but in a normally aspirated
engine, you're not gonna' make the higher power settings you need for a
good breakin at 10,000msl. You're prolly not going to be able to make
much more than 55% power, even *at* full throttle.

Would have been better to stay lower where you could make 65-75% power
with that engine during those critical, first break-in hours.
