Gents, with 69 YAK-55 registered in the USA I am astounded by the posts on
the fuel tank issue. (welding, remove tank etc)
The fuel tank is a wet wing!!! The access panel is at the root end.
Depending where the leak is will dictate how you deal with it. It is
possible that you will need to remove the wing for comfort, even so this is
not a difficult job.

Hello Mark;
I believe you are correct. I have started all three - SU-26, 29, and
-31 They all have the same starter lever, as near as I can tell.
Ah, the Yak-55. It has a push button that essentially does the same as
the Sukhoi lever. It is totally different from the Yak 52 I had from
'96-'98. I understand your explanation of the -52. I have thought
(every now and then I have one 0:)..that the leaky -55 starter button
assembly manifold thingy could be replaced with a Sukhoi lever.
When you push the button on the -55, almost an inch of throw, you slide
magic stuff inside the manifold just behind the panel causing the air to
move through the lines to the engine. This also connects a micro switch
to initiate the "shower of sparks" (?) Pushing the button takes
somewhat more umph than the -52 - since I think you are pushing against
the air valve directly.
So, -55 like Sukhoi, I think.
Respectfully, Rick b
>>> BitterlichMG@cherrypoint.usmc.mil 12/7/2005 3:04:45 PM >>>
Hey Rick,
The cockpit starting system between a YAK-50/52 and a Sukhoi is in fact
very different... not sure about the 29, but I am darn sure about the
26 and 31. Both of them use a lever that is in fact the pneumatic valve
itself! As you push on this thing... it is actually a hinged LEVER, it
mechanically opens an air portal and air goes right to the engine.
There are air lines connected to the started lever itself! As you push
the lever down it also actuates a microswitch which turns on the shower
of sparks.
On the YAKS (never touched a YAK-55 by the way) you have an electrical
starter BUTTON in the cockpit. When you push this button, it completes
an electrical circuit. This circuit provides power to two things. 1.
The Shower of Sparks system 2. A remote controlled solenoid air
valve. This remote controlled solenoid air valve then sends the air to
the engine starter distributor. The electrically controlled valve is
what is totally missing on the Suke 26 and 31 (again, not sure about the
29 or the YAK-55).
Both starter valve types can be rebuilt... agreed.... but take totally
different parts to do so.
Neither of us is stupid. In fact, I have not talked to anyone stupid
on this list server yet. Some try to come across that way on purpose,
but are actually very poor actors. :-)
I STILL am not sure how the YAK-55 system works... is it the same as
the 52/50, or is it like the Suke 26/31 ?? Andres's description makes
it sound like a 26/31 system.

Subject: RE: Yak-List: hoses
Sirs;
I've been inside the starter unit to replace rubber "O" rings. It
appears to me similar - in physics - to my -29. Pushing the round
starter button (Yak 55 "longwing") opens the valve to send air to the
engine. At the same time pushing that same button allows for an
electrical connection to close, sending those cute little electron
thingys to the shower of sparks. Hence, if you keep pushing on the
button the engine will run without having the mags on and the air gets
depleted.
If I appear stupid...my Masters work really was in Genetics.

Hello Andres,
I just got back from a Thanksgiving trip and am getting ready to leave
on a Christmas trip, so I am sorry for not writing back sooner and sorry
too that I will not be around very long to help you.
I am not up to speed on the 55m and am not sure what type of starter
system is used. It SOUNDS like you have the same starter arrangement as
is used on a Sukhoi... is it like a LEVER that you PUSH to allow air
into the starter system, or is it some kind of electrical switch that
you push in the cockpit that actuates a REMOTE air valve?
Please describe in as much detail as you can how your system works...
by that I mean, a description of the parts.
Most YAKS use a starter push button... electrical ..... It sends
voltage to turn on the shower of sparks AND sends power over to a remote
air valve (electrically controlled) that then puts high pressure air up
to the starter distributor on the engine itself.
The Sukhoi's on the other hand, use a lever... and that lever is
actually part of the mechanical valve itself that allows air to go to
the starter. On that same lever is an electrical microswitch that puts
power to the shower of sparks.
Can you tell me what you have?
Mark

Thanks Rick... that is EXACTLY the info I was looking for. Makes me wonder

Yes sir. That is what it was actually made for. On the EA-6B we inject it
into certain void spaces to stop leaks in wet wings. Externally.
I have treated four Russian tanks and have watched it used on 3 more with
small cracks. I am not recommending this procedure... but in one case the
tank was emptied and then a hose from the exhaust of a running engine was
put into the tank to get rid of the oxygen, and then the tank was ground
down to bare metal with a sanding disk that also sparked a lot.. hence the
hose into the tank.... the 8802 was/is applied right to the external surface
and extended a few inches all around the crack. One tank has the crack stop
drilled.... the one on my personal YAK-50 was not. On mine, it has been 5
years now with no sign of leakage at all. One guy put too thin a layer on
the leak and it started seeping out (fuel that is). He did not even take it
back down to bare metal, but instead just goobered some more 8802 on top and
POOF, no more leak.
I keep a supply of it on hand in the fridge 24/7. The stuff is amazing. As
long as you apply it to a clean and warm surface, it is going to work. You
do not want to apply it to cold metal in the winter time. At least not
without a heat lamp.

Walt, can you explain the difference to me someday when you have time?
Everyone I know always called it a shower of sparks. I just went along with
that term not knowing any better. I'd like to understand it completely and
it is obvious from your comment here that I do not.

Ben;
Assuming you have replaced the burnt high tension lead and conduit the next
step is to check the boost coil contact points for condition. Clean and
refurbish the points and, if necessary, adjust the point gap. If that fails
replace the boost coil.
BTW you describe the unit correctly. It is a simple boost coil system. It is
NOT a shower of sparks system.

I recently aquired a Yak 52 and have had a difficult starting it. After
reviewing manuals and opening the cowl, I discovered that the lead from the
booster coil to the left mag had burnt on the exhaust ring.....creating a
short. The booster coil is still energized when the start button is
depressed, but I'm only indicating approx. 200v going into the mag.
Has anyone had this problem or have any suggestions?
Thanks, Ben

Mark and Others,
I would recommend finding a good welder and having the crack stop drilled, and
welded. But if you can not find a welder then the next best procedure is:
stop drill the ends, to prevent the crack from continuing. Then put a patch
over the crack, prior to sealing it. The area should be taken back down to bare
metal and retreated to prevent corrosian.
Once the repair is complete, you should pressure check the tank to make sure
it will not leak again. If it does leak, you will need to conduct a leak path
analiss.
If you just put more sealant over the new leak, in a matter of time it will
return again. If you strip the old sealant, and reply you could cause anouther
leak.
The key to making a good repair is the preperation before hand. I am also a
welder and have succeded on repairs where others have failed, because I spend
a little time prepairing my welds beforehand.
Other repairs may work on a temp basis, but will eventually cause problems again.
I would be willing to bet that work hardning (small amounts of bending over
time. We as a group may want to look at ways to prevent that from happening
to our tanks, so we do not have to make repairs.
On Yak-52, this is probably cause by improper venting and expansion of the
tanks. The problem can easly be fixed with a better vent system, maybe something
like the CJ ar eusing to balance their tanks.

Subject: RE: Yak-List: hoses
Hello Mark;
I believe you are correct. I have started all three - SU-26, 29, and
-31 They all have the same starter lever, as near as I can tell.
Ah, the Yak-55. It has a push button that essentially does the same as
the Sukhoi lever. It is totally different from the Yak 52 I had from
'96-'98. I understand your explanation of the -52. I have thought
(every now and then I have one 0:)..that the leaky -55 starter button
assembly manifold thingy could be replaced with a Sukhoi lever.
When you push the button on the -55, almost an inch of throw, you slide
magic stuff inside the manifold just behind the panel causing the air to
move through the lines to the engine. This also connects a micro switch
to initiate the "shower of sparks" (?) Pushing the button takes
somewhat more umph than the -52 - since I think you are pushing against
the air valve directly.
So, -55 like Sukhoi, I think.
Respectfully, Rick b
>>> BitterlichMG@cherrypoint.usmc.mil 12/7/2005 3:04:45 PM >>>
Hey Rick,
The cockpit starting system between a YAK-50/52 and a Sukhoi is in fact
very different... not sure about the 29, but I am darn sure about the
26 and 31. Both of them use a lever that is in fact the pneumatic valve
itself! As you push on this thing... it is actually a hinged LEVER, it
mechanically opens an air portal and air goes right to the engine.
There are air lines connected to the started lever itself! As you push
the lever down it also actuates a microswitch which turns on the shower
of sparks.
On the YAKS (never touched a YAK-55 by the way) you have an electrical
starter BUTTON in the cockpit. When you push this button, it completes
an electrical circuit. This circuit provides power to two things. 1.
The Shower of Sparks system 2. A remote controlled solenoid air
valve. This remote controlled solenoid air valve then sends the air to
the engine starter distributor. The electrically controlled valve is
what is totally missing on the Suke 26 and 31 (again, not sure about the
29 or the YAK-55).
Both starter valve types can be rebuilt... agreed.... but take totally
different parts to do so.
Neither of us is stupid. In fact, I have not talked to anyone stupid
on this list server yet. Some try to come across that way on purpose,
but are actually very poor actors. :-)
I STILL am not sure how the YAK-55 system works... is it the same as
the 52/50, or is it like the Suke 26/31 ?? Andres's description makes
it sound like a 26/31 system.

Subject: RE: Yak-List: hoses
Sirs;
I've been inside the starter unit to replace rubber "O" rings. It
appears to me similar - in physics - to my -29. Pushing the round
starter button (Yak 55 "longwing") opens the valve to send air to the
engine. At the same time pushing that same button allows for an
electrical connection to close, sending those cute little electron
thingys to the shower of sparks. Hence, if you keep pushing on the
button the engine will run without having the mags on and the air gets
depleted.
If I appear stupid...my Masters work really was in Genetics.
Respectfully, Rick b

Hello Andres,
I just got back from a Thanksgiving trip and am getting ready to leave
on a Christmas trip, so I am sorry for not writing back sooner and sorry
too that I will not be around very long to help you.
I am not up to speed on the 55m and am not sure what type of starter
system is used. It SOUNDS like you have the same starter arrangement as
is used on a Sukhoi... is it like a LEVER that you PUSH to allow air
into the starter system, or is it some kind of electrical switch that
you push in the cockpit that actuates a REMOTE air valve?
Please describe in as much detail as you can how your system works...
by that I mean, a description of the parts.
Most YAKS use a starter push button... electrical ..... It sends
voltage to turn on the shower of sparks AND sends power over to a remote
air valve (electrically controlled) that then puts high pressure air up
to the starter distributor on the engine itself.
The Sukhoi's on the other hand, use a lever... and that lever is
actually part of the mechanical valve itself that allows air to go to
the starter. On that same lever is an electrical microswitch that puts
power to the shower of sparks.
Can you tell me what you have?

hello mark: I have written to you in the past, I have
a yak 55m the main starter valve is shut, the seals
are all gone inside and the small ruber gasket has
disintegrated and sent pieces to the air manifold
luckily we retrieve them all but I am in need of a
starter valve, I have not been able to locate one here
in usa, would like to get another as spare, the parts
look rather flimsy, if not available is there an
alternative I heard swage lok makes a ball valve that
may replace that fitting, it is the electromechanic
part that sets the shower of sparks at the same time
that pressurizes the engine with compressedair

It is my understanding that the recaps are of a harder material than the
original tread. I also remember hearing something about natural rubber tires
being better able to withstand the rigors of extreme temperature changes, i.e.:
80 or 90 on the ground to below freezing at altitude. I would also guess
that the fast wear may have something to do with,
on landing, 0kph to 100 kph in an instant.

Coincidence? As a number of you know I live under a MOA with a active Restricted

my hangar door when they drop 2,000 pounders.
The Navy and Army helicopters have a low altitude (200') night route right over
our airpark that they use as a check point.
Just after midnight the unmistakable sound of rotors bashing at the air as two
Apaches may one circle of our place. They do this when they need to kill time
so as to arrive right on TOT.
Than around noon two FA-18 did some contorting overhead at about 5,000 or so.
It was enough racket to pull me from my computer problem and go out side and
watch.
Than I took stock of what day this was. And I said two prayers. One for those

Your computer does seem a little jaundiced. I hope it isn't contagious.

Coincidence? As a number of you know I live under a MOA with a active Restricted
area just 4 nm south and an active live bombing range 22.3 nm SE. It rattles
my hangar door when they drop 2,000 pounders.
The Navy and Army helicopters have a low altitude (200') night route right
over our airpark that they use as a check point.
Just after midnight the unmistakable sound of rotors bashing at the air as
two Apaches may one circle of our place. They do this when they need to kill
time so as to arrive right on TOT.
Than around noon two FA-18 did some contorting overhead at about 5,000 or so.
It was enough racket to pull me from my computer problem and go out side and
watch.
Than I took stock of what day this was. And I said two prayers. One for those
at Pearl Harbor and one for the pilots over head. And as I sign off this
stupid computer for the night, I'll say one for the "boots" overseas. Without
the likes of them, I wouldn't be living under the best spot of sky on God's
green earth - with the sounds of freedom all around me.
Sleep well my fellow countrymen.

| Subject: | Re: Booster Coil |
Hi Mark;
FWIW;
Boost coil system: An induction coil similar to an old automotive ignition coil
but with a set of contact points and usually mounted in a metal container for
radio shielding.
The primary circuit is energized by the start switch inducing a high tension in
the secondary circuit (15,000 - 20,000 Volts?). This is fed to one of the magnetos
through a shielded high tension lead which connects to a special, retarded
position, finger on the distributor rotor. This finger fires the spark plugs
at approx. TDC rather than the normal BTDC setting of the mag.
In operation it totally by-passes the magneto except for spark distribution.
It can be recognized by the existance of the high tension lead.
Shower of Sparks: Back in the '40's I think this was a trade name for a "new" start
system from Bendix. I understand that currently the name is used by other
manufacturers (Lamar?). Not really sure who or if the system is technically the
same as the original Bendix. Since I only somewhat understand old things the
following is Bendix: ------
This uses an induction vibrator which produces an increased voltage that is delivered
to the magneto PRIMARY circuit. When the points open this boosted primary
results in a boosted high tension from the magneto coil to significantly increase
the output of the slow turning magneto to the spark plugs. This output
continues until the points close resulting in a continuous "shower" of sparks
unlike the single spark at point opening when the primary is produced only by
the magneto.
Typically this produces a continuous spark from the mag. BTDC setting to TDC when
the start (& mag) circuit is energized. Since this utilizes the normal magneto
circuits and does not retard the spark the engine could start backwards. The
mags (or mag!) are not turned on until the engine is turning fast enough.
This system is recognized by the absence of the HT lead and the presence of a "black"
box in the primary circuit between the switch and the mags.
I'm sure there are other systems out there now that render these quaint and obsolete.
But still, the earliest of the above is on the CJ.
Here I must make a confession - I really have no idea of what is on the Yak 50,
54, 55 or any Sukhoi. Seems to me that Dennis and I discussed this some time
back and came to the conclusion that the 52 and CJ were the same. Do I remember
correctly Dennis?
Cheers;
Walt

Walt, can you explain the difference to me someday when you have time? Everyone
I know always called it a shower of sparks. I just went along with that
term not knowing any better. I'd like to understand it completely and it is obvious
from your comment here that I do not.

Ben;
Assuming you have replaced the burnt high tension lead and conduit the next
step is to check the boost coil contact points for condition. Clean and refurbish
the points and, if necessary, adjust the point gap. If that fails replace
the boost coil.
BTW you describe the unit correctly. It is a simple boost coil system. It
is NOT a shower of sparks system.

I recently aquired a Yak 52 and have had a difficult starting it. After
reviewing manuals and opening the cowl, I discovered that the lead from the
booster coil to the left mag had burnt on the exhaust ring.....creating a short.
The booster coil is still energized when the start button is depressed, but
I'm only indicating approx. 200v going into the mag.
Has anyone had this problem or have any suggestions?
Thanks, Ben

I think we did discuss this Walt. However, with the 52 as I'm sure you know, we
start the airplane with the mag switch off if we have the standard M9F mags.
All of the 80's models with M14P's have these mags. Once the engine fires from
the booster coil, we flip the mag switch on. The additional finger on the
mag rotor is as you say, designed to fire a couple of degrees after TDC. The
M9-35 mags as used on the TW and M14PF 400HP engines are started with the mag
switch in the 1+2 position. These mags do not use a booster coil as they are
centrifugal advance mags and timed to AFTER TDC depending on the stamped number
under the cover in the boss of the mag. Usually around 5 degrees after TDC.
If I'm not mistaken, the CJ is started with the mag switch on, just like the
TW and uses a mag that is also centrifugal advance.?

Right on Dennis, the CJ can be started with the mag switch on since, at the
start, it fires at approx. 7 degs. (crank) BTDC. Not as close as the TW to TDC
but close enough. The M14P with the fixed spark mag by comparison will fire
at 23 +/- 1 deg. (crank) at the start so there is a danger of reverse start. The
mags should be off until it starts on the booster.
Does the 52 have an HT lead from the start booster to one mag? Or a box in
the primary circuit?
Cheers;
Walt

Hi John,
Have you have ever had a gas tank leak on your Yak?
It looks like my plane is developing a gas leak along the seam on the bottom
of both wings.
It would be good to know of an efficient economical way to fix it.
If you have had this problem or know someone who has, would you refer me to
them?
Thanks in advance,
Mike
