Herb,
There are many M14's out there, typically Type 1's, that do not have the
access plate on the nose case that you speak of. Since there really
isn't a crankshaft per sae, I would be interested in knowing how "he
can see the position of the crank." and what he specifically looks for
"When the crank stops in the highest 12 o'clock position".

Anyone know where to get the case acess that goes on the right side of
the case when facing the engine? We had a discussion about oil in the
cylinders and fluid lock at OSH. Yeargis has a glass cover on the case
that if I understood correctly allows him to pull the prop through after
shutdown - while he can see the position of the crank. When the crank
stops in the highest 12 oclock position then no oil siphons down into
the case. Does anyone in the US know of this mod? It seems simple and
easy to install - 3 bolts unless you have a Yak 52TW with electric
starter - then this cover is used to mount the starter. It also solves
the problem of starting with no oil. I have never heard of it or seen
it discussed, yet there it was on Yeargis' Sukhoi and Sergei knew of it
too. Any Euro's on the list know of it?

Mark,
You are correct to point out a lack of 100% fool proof systems in
airplanes. I am not aware of a single 100% fool proof system of any
kind in an airplane including Yaks and Pitts Model 12s. Why? Pilots
are human and despite the best efforts of designers and component
developers, these flawed human pilots still find ways to misuse, not
use, and abuse systems.
Your 2 bulleted points are valid but it should be noted that an
oil shut off valve does not eliminate the oil pressure gauge which
should be checked at engine start with or without a clean kit system
being installed. Airplanes with throttle switches, buzzers, barber
poles, etc., still land gear up.
I am not aware of any M14 engine loss related to an oil shut off
valve and clean kit, ours or others. Maybe someone has specific data on
this to share. I am aware of many engine losses due to hydraulic lock.
The only real method we have today is the use of check lists and
forcing the pilot to be a creature of trained habit in using various
aircraft systems. I suppose this will have to do until airplanes have
full cognitive reasoning so that they will automatically latch the door
or canopy properly, set the power, retract and extend the gear at the
proper times, handle the flaps, switch fuel tanks, fill the tanks, make
sure the gas and oil caps are secure, the pilot cover is off and the
airplane is clear of the hangar door before the door is lowered. Of
course, then there is no need for the pilot, right?
We can't make everything perfect....only progressively less bad
with each iteration. Besides, once we humans get everything in the
world absolutely correct, there would be no work for engineers, pilots,
politicians, doctors, etc. Then what will I do to earn grocery money?
Airplanes will most likely be illegal by then anyway....
Shut off valves and scavenge systems do make the M14 engine more
user friendly and less messy. However, they have to be used properly in
order to be safe.

Dennis,
Yurgis had made a white mark on the gear underneath the cover at a point
when the master rod crank bearing was at the twelve o'clock position.
He would rotate the engine after shut down until he could see his mark.
Apparently, having the master rod crank bearing at the twelve o'clock
position prevents the posibility of siphoning out of the oil tank that
can occur occasionally when a piece of carbon or whatever prevents the
check valve from closing completely.

You are correct to point out a lack of 100% fool proof systems
in airplanes. I am not aware of a single 100% fool proof system of any
kind in an airplane including Yaks and Pitts Model 12s. Why? Pilots
are human and despite the best efforts of designers and component
developers, these flawed human pilots still find ways to misuse, not
use, and abuse systems.
Your 2 bulleted points are valid but it should be noted that
an oil shut off valve does not eliminate the oil pressure gauge which
should be checked at engine start with or without a clean kit system
being installed. Airplanes with throttle switches, buzzers, barber
poles, etc., still land gear up.
I am not aware of any M14 engine loss related to an oil shut
off valve and clean kit, ours or others. Maybe someone has specific
data on this to share. I am aware of many engine losses due to
hydraulic lock.
The only real method we have today is the use of check lists
and forcing the pilot to be a creature of trained habit in using various
aircraft systems. I suppose this will have to do until airplanes have
full cognitive reasoning so that they will automatically latch the door
or canopy properly, set the power, retract and extend the gear at the
proper times, handle the flaps, switch fuel tanks, fill the tanks, make
sure the gas and oil caps are secure, the pilot cover is off and the
airplane is clear of the hangar door before the door is lowered. Of
course, then there is no need for the pilot, right?
We can't make everything perfect....only progressively less
bad with each iteration. Besides, once we humans get everything in the
world absolutely correct, there would be no work for engineers, pilots,
politicians, doctors, etc. Then what will I do to earn grocery money?
Airplanes will most likely be illegal by then anyway....
Shut off valves and scavenge systems do make the M14 engine
more user friendly and less messy. However, they have to be used
properly in order to be safe.

Anyone know where to get the case acess that goes on the right side of
the case when facing the engine? We had a discussion about oil in the
cylinders and fluid lock at OSH. Yeargis has a glass cover on the case
that if I understood correctly allows him to pull the prop through after
shutdown - while he can see the position of the crank. When the crank
stops in the highest 12 oclock position then no oil siphons down into
the case. Does anyone in the US know of this mod? It seems simple and
easy to install - 3 bolts unless you have a Yak 52TW with electric
starter - then this cover is used to mount the starter. It also solves
the problem of starting with no oil. I have never heard of it or seen it
discussed, yet there it was on Yeargis' Sukhoi and Sergei knew of it
too. Any Euro's on the list know of it?

The rudder pedals on the 55m look to be adjustable in the fore/aft
postion. The way the pedal assembly mounts to the horizontal tube
(parallel to the longitudinal axis) looks like it's intended to slide
fore/aft on this tube. Is the adjustment as simple as removing bolt,
reposition pedal assembly, drill new hole, hope long legs fit better?
My seach of the archives didn't turn up any info.

I'm about to tackle the mysterious Yak-52 fuel feed problem. Figured I'd first
remove the caps and drain five or ten gallons to see if it was a blocked vent
problem. Then, if still a problem, I'd check the lines and one-way valve. Are
the fuel lines and valve easily accessable? I think there are inspection panels
on either side of the sump drain. Will these give me access to the one-way
valves and fuel lines? I've read in the archives about dimpling the flap
in the valve. Any other advice would be appreciated.

Dennis,
I have seen the kit on Jurgis' SU31. He assembled the airplane here at our
shop when it came into the US earlier this year. There are marks made on the
gears to help you align the crank to a certain position. In that position,
the valves and pistons on the lower jugs are set such that the amount of oil
that can get into the lowers is minimized. It doesn't really stop any flow
potential. He says it doesn't really do the trick as evident by the mess on
the floor.
He has some of our kits to install on his 3 airplanes this winter.

M14 oil/taps etc=0A

1.. The crank shaft position indicator concept came from Sergio Dallan in
Italy. For a while he sold a kit combining that with an oil tap, very sim
ilar to the Kimball's. In it's final version the access to the tap goes th
rough a small door on the side of the engine cowling, and an additional saf
ety factor was a "barbers pole" protruding through the top of the cowling,
when the tap is shut. =0A
2.. Vedeneyev themselves came up with an ingenious (and very simple) solu
tion to oil in the in-take tubes. It has similar drains, but rather than d
ripping outside or into cans, the system was fully automatic, draining inta
ke tube oil into a one litre container mounted as part of the engine. Af
ter start up, a separate pipe slowly took the oil from the tank through man
ifold vacuum and into the cylinders. An additional advantage is the extra
oil provided on start up. It had a series of small check valves which aut
omatically shut the system off during normal running. It worked well, but
Vedeneyev are desperately conservative, and would not sell it because it is
not certificated, and in Europe we cannot use stuff that is not. =0A

Just to address the hyd lock issue that happened here. You win the bet
Doc. There appears to be strong proof that the pilot didn't even
bother to pull the prop through at all. The 52 did not belong to him,
but in fact to two other fellas. They being "Good ole Boys" allowed
this guy to fly their 52. The pilot just hopped in and cranked the
thing right up. Apparently he had been doing this for some time... the
first time by accident.... but when nothing happened THAT time, he
decided that it was all a waste of time anyway. He actually got away
with it longer than any of us might imagine. On the day in question,
there was oil blown back 10 feet in a spray pattern from the exhaust
from the initial start. Imagine that. 10 minutes after takeoff the
engine started shaking... rather violently. He managed to get back to
the airport safely. Piston rod broken, damage all over the place... too
much for any chance of repair.
Wait.. it gets better.
This same gent wrecked a Pitts S-1 when he took it up on his first
flight after purchase (without any kind of checkout what-so-ever) and
then tried to land it with an 18 knot crosswind. He slid off the
runway, then tried to take it around, hit a runway marker, then
cartwheeled down the runway. He walked away with a few scratches.
Pitts was totalled. By the way, there was another runway facing
directly into the wind, but his girlfriend would not have been able to
watch him land on THAT runway. He had never flown a Pitts before, and
his last tailwheel time was 2 years earlier... in a Skybolt.
Of course, then he was violated from the tower for doing aerobatics
within the Class D.
He still has his ticket, and he still is flying... a twin now.
All this in less than one year.
Truth is more bizarre than fiction folks.

Saying all that, it still seems the Russians pretty well thought of
everything with the oil shut off valve in the oil pump. Had to clean
mine about two years ago and have not had any problems with it since. I
realize the Kimballs have some good stuff. Their intake drain being one.
I have noticed that my drain valve on the 50 does leak some after the
valve is close and have seen it doing it after engine shut down. Yes it
is fully closed too. So nothing is perfect. It is up to us the pilot in
charge to make sure our steads are airworthy.
10 to 1 the hydraulic lock occured because some one shorted the pull
through. 8 blades being the minimum. I prefer 14. If there is oil
draining from the intake or and exhaust stack, I pull more. If there is
resistance to pulling the blade forward, I do not pull any farther. If
it is solid, then rocking the blade back slightly will usually open a
valve and the oil will puke out. If it is not moving, the off comes the
cowling and the spark plugs are pulled. Since I already have a drain kit
I do not pull the intake plugs.
Early on I asked why there was not a manual oil cutoff valve to prevent
an overflow that occures when the check valve is grunged up and allowing
oil to overflow. After seeing that the check valve that the Russians
invented was so efficient at keeping oil in my tank (particularly, I a
little preventative maintenance was done regularly), I decided not to
break a system that was not broke. If it is broke, then fix it.

--> Yak-List message posted by: "A. Dennis Savarese" <dsavarese@elmore.rr.com>
Scooter,
The uneven fuel feed is perfectly normal in the 52. Most feed from the left
tank first down to about 40-45 liters and then the right starts to come
down. First try flying the airplane with your feet off the rudder pedals
and see if the airplane is yawing left or right. First correct the yaw
problem before you go digging into any fuel feed problem. BTW, the
inspection panels under the wing root panels will not give you access to the
fuel valves. They are under the front seat in the junction where the fuel
lines from the left and right tanks come together. The fuel lines coming
into this junction connect directly to the main fuel tanks. You'll have to
remove the lower wing panels to get to these fittings.
You can easily check the vent lines by removing the fuel cap on one tank and
blowing hard into the fuel vent line under the fuselage or you can use
regular shop air. Have someone listen at the tank opening. They should
hear the air bubbling through the tank. Repeat the procedure for the other
tank.
As I said earlier, unequal fuel feeding is very common and it is because we
tend to use a lot of left rudder. So please don't overreact to the unequal
fuel feed. Now if it goes down to 20 liters on one side before the other
side starts to feed, you may want to inspect the valves at the junction
under the seat.
Hope this helps.
Dennis

Scooter,
I would agree with what Dennis said but add that it is worthwhile to level the
airplane side-to-side on the jacks with a level across the canopy rails. Once
that is done, tweek the adjustable ball levels on the T&B and AH. Helps to know
whether the error is out-of-rig or just misadjusted guages. I admit to finding
skid/slip balls out of whack on my airplane, causing me to hold some rudder.
Happens often after periods of acro.

initial start. Imagine that. 10 minutes after takeoff the engine started shaking...
rather violently. He managed to get back to the airport safely. Piston
rod broken, damage all over the place... too much for any chance of repair.
Wait.. it gets better.
This same gent wrecked a Pitts S-1 when he took it up on his first flight after
purchase (without any kind of checkout what-so-ever) and then tried to land it
with an 18 knot crosswind. He slid off the runway, then tried to take it around,
hit a runway marker, then cartwheeled down the runway. He walked away with
a few scratches. Pitts was totalled. By the way, there was another runway
facing directly into the wind, but his girlfriend would not have been able to
watch him land on THAT runway. He had never flown a Pitts before, and his last
tailwheel time was 2 years earlier... in a Skybolt.
Of course, then he was violated from the tower for doing aerobatics within the
Class D.
He still has his ticket, and he still is flying... a twin now.
All this in less than one year.
Truth is more bizarre than fiction folks.

Saying all that, it still seems the Russians pretty well thought of everything
with the oil shut off valve in the oil pump. Had to clean mine about two years
ago and have not had any problems with it since. I realize the Kimballs have
some good stuff. Their intake drain being one. I have noticed that my drain valve
on the 50 does leak some after the valve is close and have seen it doing it
after engine shut down. Yes it is fully closed too. So nothing is perfect.
It is up to us the pilot in charge to make sure our steads are airworthy.
10 to 1 the hydraulic lock occured because some one shorted the pull through.
8 blades being the minimum. I prefer 14. If there is oil draining from the intake
or and exhaust stack, I pull more. If there is resistance to pulling the blade
forward, I do not pull any farther. If it is solid, then rocking the blade
back slightly will usually open a valve and the oil will puke out. If it is
not moving, the off comes the cowling and the spark plugs are pulled. Since I
already have a drain kit I do not pull the intake plugs.
Early on I asked why there was not a manual oil cutoff valve to prevent an overflow
that occures when the check valve is grunged up and allowing oil to overflow.
After seeing that the check valve that the Russians invented was so efficient
at keeping oil in my tank (particularly, I a little preventative maintenance
was done regularly), I decided not to break a system that was not broke. If
it is broke, then fix it.

Kevin, you are absolutely correct and I agree with every word you have said. I
believe in your system(s), and plan on purchasing them, or at least some of them,
myself.
That said, I am sure that if every M-14 equipped aircraft had the shut off valve,
sooner or later some yahoo would manage to start one with the valve off. Right
now, the ones equipped with the valve are a very small minority.
If after this discourse, anyone has any doubt at all, let me make one thing perfectly
clear: I believe that Kevin Kimball and his associates produce some of
the finest parts and come up with some of the best ideas (relating to just about
anything and everything) that I have ever come across. I recommend his aircraft,
his products and his accessories without doubt or question. If this sounds
like a commercial.... sorry, but I believe when someone deserves praise,
they ought to get it, just as when someone is a crook, the world needs to know
THAT... no punches pulled. I am a strong advocate and supporter of every single
thing Kevin's company stands for, has made, or has on the drawing board.
We're lucky to have someone like him around.

Mark,
You are correct to point out a lack of 100% fool proof systems in airplanes. I
am not aware of a single 100% fool proof system of any kind in an airplane including
Yaks and Pitts Model 12s. Why? Pilots are human and despite the best
efforts of designers and component developers, these flawed human pilots still
find ways to misuse, not use, and abuse systems.
Your 2 bulleted points are valid but it should be noted that an oil shut off valve
does not eliminate the oil pressure gauge which should be checked at engine
start with or without a clean kit system being installed. Airplanes with throttle
switches, buzzers, barber poles, etc., still land gear up.
I am not aware of any M14 engine loss related to an oil shut off valve and clean
kit, ours or others. Maybe someone has specific data on this to share. I am
aware of many engine losses due to hydraulic lock.
The only real method we have today is the use of check lists and forcing the pilot
to be a creature of trained habit in using various aircraft systems. I suppose
this will have to do until airplanes have full cognitive reasoning so that
they will automatically latch the door or canopy properly, set the power, retract
and extend the gear at the proper times, handle the flaps, switch fuel
tanks, fill the tanks, make sure the gas and oil caps are secure, the pilot cover
is off and the airplane is clear of the hangar door before the door is lowered.
Of course, then there is no need for the pilot, right?
We can't make everything perfect....only progressively less bad with each iteration.
Besides, once we humans get everything in the world absolutely correct,
there would be no work for engineers, pilots, politicians, doctors, etc. Then
what will I do to earn grocery money? Airplanes will most likely be illegal
by then anyway....
Shut off valves and scavenge systems do make the M14 engine more user friendly
and less messy. However, they have to be used properly in order to be safe.
