The Murphy Builders Site

Hi all,
I'm still looking at whether to buy a new clone engine or a mid-time. A
friend of mine sells used parts for a salvage yard and come across a 1998
Lycoming 0360A1A wide deck 180HP. It came out of a Glastar, has all acc on
it, dynofocal, 120 hr since new. The engine has had a prop strike and it
is bent. The engine is guaranteed to only have only a bad crank and other
components ok. I would do my own engine repairs with some assistance from
an IA friend. I have been in the engine rebuilding business all my life,
not aircraft though but an engine is an engine when it comes down to it.
Looking for any advice from the group. I don't know what wide deck means,
is that ok for the Elite?
Thanks,
Mike Betti

I'm by no means a Lycoming expert Mike, my aviation maintenance history is
on jets, and I'm only an 80 hour pilot... but most if that time is in a
Cherokee 180, and there's a tickling in the back of my mind that says the
A1A model has a hollow crank for constant speed props... and to go along
with that whether using the CS prop or not, there are some operating
limitations involved with this engine in certain RPM ranges due to
viabrations that are not there on the non-hollow crank engines.

What sticks in my mind about this was that the range to avoid was right
where I usually found myself cruising in the Cherokee, which thankfully did
not have this model engine, therefore did not have the limitation. I just
remember thinking it sure would suck not to be able to fly at what appeared
to be a real sweet spot for both the engine and airplane.

I don't know if you can use a different crank when you rebuild or not... but
I'm sure somebody here does.

Mike

Thanks,
MAM has used this model for their Elite as did Al H. There was a fixed pitch
prop on this one also. I've heard about the balance problem and that maybe you
can have it balanced during rebuild. I know some of the clone builders are doing
that, but I don't know what's involved. I just found out all later model
Lycomings are wide deck.

Mike,
The wide deck is fine. As for an engine is an engine, how many
automotive
engines have silk thread between the case halfs? Did you know if you
don't
install it, it will pinch the bearings?Are you aware of the various
crankshaft
AD"s? If your going to do your own, at least make a seminar or get an
experienced aircraft engine mechanic to guide you through the lower end.
The
cylinders are a breeze. IMHO
