Also not mentioned before in this thread:
On our Yak-52; we have installed a shut off valve just below the oil tank.
This
valve is closed after each flight to prevent oil draining into the engine w
hen
parked. When closed it flicks a switch that disables the ignition system to
prevent starting. Not sure if this easy modification is common or will prev

all hyd lock issues caused by oil, but seems logical to me.

RE: our beloved M14 & Housani engines and their idiosyncrasies
Dear ALL
I have a standard M14 P in my Yak18T to which we have fitted the
intake drains.
We noted the sludging of oil previously mentioned in the list, particularly
in winter & observed the gradual clearing of fuel colour noted by Mark &
others on the list. This washing out of the intakes is now SOP. It also
seems to work better with a pilot(my wife) priming the engine whilst I turn
the blades, I'd guess the spinning supercharger impellor is helping??
We have recently fitted sump oil heaters to all 3 aircraft, M14P(sump & oil
tank), Lyc IO 360 & 0 320. Winter is not yet fully here but the results
have been thus far impressive.
Oil sits at about 30-35 deg C in all engines, cylinder temps between 25-35
deg C in all engines. We have cowl covers on all & overnight temps to date
are -1 de C
The oil drain from the M14 has been a little more obvious but the big
changes are no thick oil at all, rapid clearing of the intake drain to clea
r
avgas & oil temp to 40 deg C within 5-7 min at ambient of 0 to 7 degC. Prio
r
experience was that it took about 20 minutes to be ready for taxi. All
engines now warm very quickly, so far in less than 10 minutes all 3 are
ready to launch.
Will report mid winter, where we expect ambient to be below 0 deg C most
nights for 2-3 months.
I have a question re CHTs in the M14 P. We have fitted a digital cht gauge
,
expecting the worst but the results so far have been rather lower than
expected. At TO(95% & WOT) & climb(80% & 800mm MP) gills wide open, 105-7
kn, 500f/min cruise climb the top 2 cylinders run about 190 C, the lowest 2
run 160 deg C. At cruise setting to achieve 180 HP at 6000-10000 ft i have
to almost completely shut the gills, run the carby heat all the time
(ambient typically 5 to -5 deg C) but the lowest 2 run hottest, usually 160
with the top 2 only just staying at 130 deg C.I understood the spread was
from lean mix at the top but why the reverse at cruise?
So any explainations re chts??
Cheers

Subject: Yak-List: Another Hydraulic lock tip
With the prop stopped at or near TDC on #1 cylinder, all the lower pistons
(and
rings) are close to BDC while the upper cylinders are near the top of their
stroke.
Does not matter whether compression stroke or not.
This position works to minimize drain down for both short and especially lo
ng term
storage. All other precautions as described in the manuals should be taken
as well for longer term storage.
For the M-14P series I engines and Huosai engines, I would remove the front
plug
on #5 and then use a wooden or AL rod to find Bottom Dead Center on #5. Doi
ng
so means #1 will be Close to it's TDC position. For M-14P Series II engines
I have an quicker solution on my web site.
And as a note, I always pull through the primed cylinders (Mags off!) and o
pen
my intake drain kit before a start. My thought is that there may be a *lot
* of
engines out there with link pins that have been stressed at one time or ano
ther.
Doesn't mean that they are going to fail but perhaps some day during a star
t
when another slug of oil is in the wrong place at the wrong time.

Just a comment about bending a rod by hand-propping:
When I hand prop the M-14P, I am making that engine move through a compression
stroke FAR faster than the normal compressed air starter ever could.
Lever arm length (prop) with big guy on the end equals one heck of a lot of force.
Of course, I am rather "big".
Then we have to talk about being stupid. Let's say the prop is pulled through
by hand and then just stops because there is oil in the cylinder and the piston
now is in a hyd. lock condition. Which do you think would put more force on
a link rod at this point? Hitting the starter and putting compressed air into
the engine, or a 250 pound man hanging from the end of the prop?
I believe there is no question that a rod could be bent by "hand" (per se). I
believe the reason we don't see if happen that often (if at all) is because most
of us don't hand prop and are also educated enough not to do something quite
this dumb.
Of course with the engine in the Yak-52 where it happened here, the guy who was
flying it forgot to pull it through, so he asked someone else to do it for him.
When the gent pulling it through said: "Hey, the prop won't turn anymore",
the pilot said: "Stand Back, I'll clear it with the starter!".
Like I said, sometimes we have to talk about being stupid.

Jill, you said:
"We see more accessory shaft damage with hydraulic lock than with a prop
strike teardown."
Are you sure you did not mean it the other way around? When the engine
is turning over during a start process it is turning over very slowly.
If there is too much oil in a cylinder, you end up with the piston being
between a rock and a hard place, meaning that the link rod is pushing
it, and it simply can't move any further "up" because the oil cannot
compress, so something has to "give", and that typically is the piston
rod, and it BENDS. There does not have to be any sudden change in
rotation speed during this process. With no sudden change in rotation
of the crankshaft, I fail to see how the accessory shaft would be
damaged at all.
On the other hand, during a hard prop strike, there is a lot of MASS
moving at high speed and any sudden change in crankshaft RPM will most
certainly damage the accessory shaft. In fact, the first inspection
that should ever be done on an engine that suffered a prop strike is to
see if the timing of the MAGS has shifted. It timing has changed, then
most certainly the accessory shaft has been twisted, and a complete
engine tear-down is mandatory.
Of course, every once in awhile a hydraulic lock situation will result
in the rod being bent enough where the bottom piston ring drops out of
the cylinder itself and "jams" the engine. In this one specific case, I
could see where stress would be imposed on the accessory shaft, but
again nowhere near as much as would be the case in a sudden change in
engine RPM caused by a Prop Strike, or sudden engine stoppage at speed.
Energy = mass times speed. The accessory shaft bends as a function of
the spinning mass it is driving versus the change in speed of the force
driving IT. If the speed of the driving force changes very suddenly,
the output mass energy will cause the shaft to twist.
The short version is this is: The faster the RPM of the engine when it
has a sudden change in speed, the more likely the accessory shaft will
twist.
You're saying that bending a piston rod will cause this (twisting the
accessory shaft) more often at starting RPM, than a prop strike
occurring with the engine developing power at running speeds? If you
say so OK, but it is hard to fathom.

Subject: Yak-List: Re: Hydraulic Lock
Group,
A lot of good comments this morning. I have a couple of items to add:
A link to an article that Carl wrote in 1995; which is relevant to any
radial engine owner: http://www.m-14p.com/hydraulic_lock_cwh_1995.pdf .
We recommend against replacement of a link rod in the field. The rod
may
not be the only damage to the engine. Typically, the rear cheekplate on
the
crank will turn. (This is secured with a pinch bolt.) If the engine is
not
torn down with this existing condition, you will be flying with a wobble
on
the front end of the crank. In turn, the cam drive gear will bind and
the
teeth will shear. The dual drive gear also typically fails. You have now
set
yourself up for a catastrophic engine failure. If you sell your
airplane to
someone and do not reveal and perform a field repair of replacement of
the
link rod only, you are putting them in harm's way. (My opinion.)
Besides overhauling the M-14P, we do a lot of hydraulic lock and prop
strike
teardowns. We see more accessory shaft damage with hydraulic lock than
with
a prop strike teardown.
I think pulling a prop through 50-60 times may be great aerobic
exercise,
but unnecessary. Yes, fear is good motivator and insurance against
hydraulic lock. It does not take many blades on a 2- or 3-bladed prop
to
make sure you do not have hydraulic lock. If the cylinders are full of
oil,
of course, it will take more to clear them.

Didier,
I've put an electric heater on the oil tank itself, and have seen them mounted
on the sump as well. These are typically "EZ-Heat" type devices:
http://e-zheat.com/shop/
My oil cooler has also been changed "back" to having a veratherm (basically a thermostat)
internal to the oil cooler itself. This serves two purposes, first
it allows the oil to warm up must faster, and two ... it helps to prevent an
over-pressure situation in the cooler when the engine is started under very cold
conditions without pre-heat. There was actually a change in the YAK-50 design
that pulled these things OUT of the oil cooler at one time. I'm not sure
why, maybe Richard Goode might know. In any case, mine works very well.

Nobody mentioned that when parking for a long time you'll loose less time and
sweat to drain all oil out of the motor. And when coming back before starting
warm the oil outside the plane before putting it back. Then you'll be sure that
there can't be oil in your lower cylinder?
Plus oil will be warm before starting
The best system may well be this pre oiler and heater but it does cost money. Ok
less than a bent rod!!!
Has anyone on the list experienced such way of doing?

shutting down, and leave that in the aircraft. When you come back, you will then
know how much oil has gone into the engine!

Interesting.
I also did put on my main tank EZ Heat systems. Two pads and on the oil
sump one pad.
A very very good aftersales service.
One of my pas did not work and without any question they sent me a
replacement.
Since now 3 years I am using them and it works perfectly fine.
Works very well. When temperature is below minus 5 you must also use an air
heater to warm cylinders and it take about 40mn to warm up to 10 degres oil
and 15 degres cyl temp.
That's really great to start warm
Good to share experience on that

Particularly when the temps get below 0 C it is a VERY good idea to have
a heat pad on the oil cooler or use some sort of heater to warm the oil
in the oil cooler.
I know of one that literally blew apart in the very cold winter weather
when the oil tank and sump and engine compartment were heated, but the
oil cooler wasn't.

Thanks for your order! Our kit is made to fit both motors. We just need to know
if you have the carb heat horns installed on your aircraft as that changes
the length of one hose. Our kit is made from braided hose, is simple to install,
and easy to access.
Please contact me directly for more information at info (at) worldwidewarbirds.com
Happy Flying!

I do Rico. The problem is that it is one the maintenance posters that I go
t from West London Aeroclub. They are at the hanger so it will be tomorrow b
efore I can get a pix of it. If memory serves George Coy's website has the Y
AK 52 parts manual among others on it. There is a blow up of the compressor i
n the parts manual.sorry man, that is about the only thing on the M-14 that I
have not torn apart. ;^))
