1976 Overhaul, 1100 Hours..Pass???/

Exactly why I offered the advice that I did. Namely, pulling a cylinder
is not what most think of as a "normal" prebuy operation. Also, the
suggestion may get a "smart" reply or outright laugh.

I agree that pulling one jug gives you a limited view. What are you
looking for? Well, how about a lobe that is ground off 30-50%? for
starters. If you catch a copy of Light Plane Maintenance, they have an
easier way to determine this on all the lobes by dial gauging the backs
of the tappets. Still requires some disassembly, but nowhere near as
radical as pulling a jug. Please don't mix up the pushrods.

Since Lycomings may run fine with a lobe seriously ground off, this may
be a better alternative.

Above all, as I said, chances are that any "unusual" requests (like
these) beyond the normal "once over lightly pre-buy" will likely be
rejected.

Sarcasm and anger noted below, although I'm not sure what I said to
provoke it.

Good Luck,
Mike


OK, let's say that you pull a jug for "inspection". Exactly what do you
expect to find by this? Where is this "rust" going to be? At BEST you will
see four camshaft lobes. That isn't going to tell you squat except for
those four lobes. If the engine has been run recently, all the splash hot
oil will have removed any rust particles you have a chance of seeing.

Now you've pulled the jug. New rings, a hone job on the cylinder, new
cylinder gasket kit, change oil to breakin oil, and for what? And who is
going to pay for it? Lemme TELL you who is going to pay for it, buy the
airplane or not. And if the airplane doesn't break in properly within a
couple of dozen hours, guess who gets to pay for the REdo. You do, redo and
all.

Airplanes are best sold on the "this is the price, no matter what your
mechanic finds" basis. You find some stuff that doesn't make you want to
buy, that's fine. No problem. See ya later.

. Others also balked about pulling

a jug for a prebuy. Normally, it is true that this is not done. There are
plenty of uninformed buyers with enough credit to buy a bird uninspected
and sight unseen. So, an unusual request like pulling a jug will no doubt
get you a firm "No F^@%!*G Way" of some kind of robust belly laugh.
