In regards to the silver plating on the master rod journal, I believe there is
a lead coating that protects the silver. It is this lead coating that is attacked
by lead scavenging compounds in some aviation "flat engine" oils that does
the damage. AD oils designed for radials do not include same.
In automotive oils, compounds include zinc and sulphur additives meant to reduce
wear. These additives can erode the lead exposing the silver to acids. One day,
the whole mess just seizes up and stops turning. This has happened to large
radials, removed from long-term storage and filled up with modern "racing" oils.
I remember an Oshkosh seminar where X-rays of the crank journal where an
important part of the OH process.
Be careful what you dump into the oil.

My Yak 18T last flew when she was in Russia. Rather a shock for her to
face the Summer heat of Virginia this week - 100 to 105 F. We have had some
problems with high CHT when climbing and it has been hard to reach figures
below 200 C (orange sector). Has anybody ideas of how we can keep in the
green with these ambient temps. Thanks.

Use a larger MT type prop/spinner to duct the air better. GT propellers
just came out with a similar size spinner for the v530 prop that should
also do the trick. It will also allow a proper dynamic balance of this
prop.

You need to change the compensating jet in the carburettor.
I suspect that 80% of owners do not even know what this is,let alone how to
change it which is very simple-5 minutes only.
In fact it is a good idea to change between summer and winter,particularly
when there is a big temperature change between them.

Has anyone actually been able to purchase one of the GT propeller larger
spinners? I know they are being advertised. But no one has them and
from what I've been able to determine, no dealer has been able to get
them either.

200 degrees C is certainly not unusual during climb out when it's 100
degrees F outside and the M14 manual permits continuous operation at
that temperature. What temperature does it run at when in straight and
level cruise flight?
IF when you change the compensating jet you feel the engine hesitate or
cough when pushing the power up, (gets your attention, particularly on
short final), you will need to change to a smaller jet. If I'm not
mistaken, the smallest jet in the set is .9 mm and many times even
installing the .9 mm jet does not stop the hesitation on power up.
Richard is right though. It only takes 5 minutes to change the jet.
And 10 minutes to re-safety wire the plug. :-))

Thanks Dennis - any suggestions as to size I should start with and range
of jets I should have. When we got to 7000ft CHT just about got into green
and then we had to close oil cooler door partially to keep oil temp in range

The jets go from 0.9mm to 2.1mm.Of course most in use are between 1.2 and
1.9.
You can only try by checking what you have,then trying a jet 1 or 2 sizes
smaller.
Since they are compensating jets,a smaller jet give a richer mixture.

They have just become available in the last week or so. I have not seen
one yet, but have looked at the design. Same general size as large MT
spinner for MTV9. There must be at least 20 orders in place for them at
this time.

And if you ignore that advice and set the gap to around .032 like you
would do in your old Chevy, you can expect the aircraft to NOT START
when it gets hot. Ignore the gap advice from Dennis at your own risk.
My A&P helped me put those plugs in about 2 years ago and he gapped them
at .032 I worked for over 6 months trying to figure out why the
engine would not start once it got hot. Strangest problem I have worked
on in quite awhile.
Long story short, it turned out to be something so simple as spark plug
gap.

Steve,
If you are not experiencing any hesitation on power up when the engine
is at operating temperature, you could increase the jet size by .1mm.
Basically, you need to find out what size is in the carburetor first.
Then keep increasing the jet size by .1 mm while being cognizant of the
fact that you may begin to experience the hesitation I previously
mentioned when you push the power up quickly.
Another question would be, how do you know the instrument reading is
accurate? What cylinder is the temperature probe installed on?

200 degrees C is certainly not unusual during climb out when it's 100
degrees F outside and the M14 manual permits continuous operation at
that temperature. What temperature does it run at when in straight and
level cruise flight?
IF when you change the compensating jet you feel the engine hesitate
or cough when pushing the power up, (gets your attention, particularly
on short final), you will need to change to a smaller jet. If I'm not
mistaken, the smallest jet in the set is .9 mm and many times even
installing the .9 mm jet does not stop the hesitation on power up.
Richard is right though. It only takes 5 minutes to change the jet.
And 10 minutes to re-safety wire the plug. :-))

You need to change the compensating jet in the carburettor.
I suspect that 80% of owners do not even know what this is,let alone
how to change it which is very simple-5 minutes only.
In fact it is a good idea to change between summer and
winter,particularly when there is a big temperature change between them.

Is all this being based on a climb on a 90 degree (F) plus day, where
the cylinder head temps got into the yellow during a high power climb?
I mean heck.... If so, that is pretty much a normal indication in my
personal opinion.
Another factor is that we do not know what climb speed that was being
used! If someone was running high power on a super hot day and had the
speed down to Vx, or even Vy, then what the heck, the darn thing is
going to get HOT.
Consider pushing the nose over, and climbing at a higher speed.
Consider step climbing and reducing the power to cool off. Another
important tidbit that impacts engine temps during high power climbs is
the timing on the mags. It isn't always a fuel issue, it can also
easily be a timing issue.
I am not arguing against changing compensation jetting, but this
aircraft is being flown in Virginia with some of the highest
temperatures for that area in recorded HISTORY! I mean it! Today in
North Carolina, we are expecting to set a new temp. record for this date
and time. If the aircraft is being sold and moved to a different area,
I would strongly suggest not messing with the carb until it gets to it's
new home and this issue is looked at again.
Just my 2 cents for a reality check. Not to mention you are only
looking at one cylinder, and you also do not even know if the instrument
you are looking at is accurate! (As Dennis noted) Step back and look at
this again carefully Steve.
Mark

Try moving the temperature probe to the rear plug of #4 cylinder and see
what the reading is. The Yak 52's temperature probes are under the rear
spark plug of #4 cylinder. Although I have seen them at times on #2 and
#3 cylinders as well.

Is the Russian one basically the same as the Chinese one in the CJ?
My friend's CJ has a "lazy" attitude indicator in the front... gets confuse

Thanks Mark you are right as usual. We have 105 F advisory today and is
probably hotter out here in the sticks. No flying today. New owner will no
doubt sort it when back in Washington State. Steve

Is all this being based on a climb on a 90 degree (F) plus day, where
the cylinder head temps got into the yellow during a high power climb?
I mean heck.... If so, that is pretty much a normal indication in my
personal opinion.
Another factor is that we do not know what climb speed that was being
used! If someone was running high power on a super hot day and had the
speed down to Vx, or even Vy, then what the heck, the darn thing is
going to get HOT.
Consider pushing the nose over, and climbing at a higher speed.
Consider step climbing and reducing the power to cool off. Another
important tidbit that impacts engine temps during high power climbs is
the timing on the mags. It isn't always a fuel issue, it can also
easily be a timing issue.
I am not arguing against changing compensation jetting, but this
aircraft is being flown in Virginia with some of the highest
temperatures for that area in recorded HISTORY! I mean it! Today in
North Carolina, we are expecting to set a new temp. record for this date
and time. If the aircraft is being sold and moved to a different area,
I would strongly suggest not messing with the carb until it gets to it's
new home and this issue is looked at again.
Just my 2 cents for a reality check. Not to mention you are only
looking at one cylinder, and you also do not even know if the instrument
you are looking at is accurate! (As Dennis noted) Step back and look at
this again carefully Steve.

Steve,
If you are not experiencing any hesitation on power up when the engine
is at operating temperature, you could increase the jet size by .1mm.
Basically, you need to find out what size is in the carburetor first.
Then keep increasing the jet size by .1 mm while being cognizant of the
fact that you may begin to experience the hesitation I previously
mentioned when you push the power up quickly.
Another question would be, how do you know the instrument reading is
accurate? What cylinder is the temperature probe installed on?

200 degrees C is certainly not unusual during climb out when
it's 100 degrees F outside and the M14 manual permits continuous
operation at that temperature. What temperature does it run at when in
straight and level cruise flight?
IF when you change the compensating jet you feel the engine
hesitate or cough when pushing the power up, (gets your attention,
particularly on short final), you will need to change to a smaller jet.
If I'm not mistaken, the smallest jet in the set is .9 mm and many times
even installing the .9 mm jet does not stop the hesitation on power up.
Richard is right though. It only takes 5 minutes to change the
jet. And 10 minutes to re-safety wire the plug. :-))

You need to change the compensating jet in the
carburettor.
I suspect that 80% of owners do not even know what this
is,let alone how to change it which is very simple-5 minutes only.
In fact it is a good idea to change between summer and
winter,particularly when there is a big temperature change between them.
Alfonz at wlac has sets of the jets.

Jon,
It could be one of two things. It's not getting enough power (inverter
going TU) or it's bearings are shot or needing lube. Most likely it's the
bearings, after 20 to 30+ years they are needing attention I'm sure. I have
one CJ A/H new in the sealed can in stock if needed. Also have 3 of
the earlier units which fit Yak 18, 18A, also new sealed in the original tin
cans.
Best,
Doug

Try the FAA TSO'd RC Allen. After hard acro they will sometimes lose thems
elves but they re-erect automatically and are certified. They require no
pitot static inputs like the Dynon units and are thus not susceptible to
erroneous indications if a pitot or static is in error. One of our team
lost input to his unit at bad point in the flight and was down to a turn
coordinator. That sucks in a yak!

G'Day Dennis.
I sell GT props here in Australia.
The prop is, without doubt, a far smoother prop and does offer more
performance, in the climb, in the cruise and is a very noticeable
improvement in aerobatics.
But I cannot lay my hands on one of these spinners.
I have customers for them and cannot yet supply.
I this morning have send GT Propellers an email, in red, Asking for
update on the spinners.
I shall post the reply.
Cheers,
Chris.

Use a larger MT type prop/spinner to duct the air better. GT
propellers just came out with a similar size spinner for the v530 prop
that should also do the trick. It will also allow a proper dynamic

Doc, I believe the SAE60 part of the range (viscosity at high temps) would

equivalent to 50 weight oil (very thin). A great thing if it works right,

Phillips X/C 25W60 is not semi-synthetic. The only aviation semi-synthetic
that I know of is Aeroshell 15W50.
The Precision Engines letter was excellent in that it explained in detail
the reason for the caution notes in the P&W SB.
I totally agree that 15W50 and 20W50 should not be used in radial engines
(and I would include the smaller ones). 25W60 on the other hand is probably
OK for the small radials. It is nominally equivalent to 120 at higher
temperatures (60 SAE = 120 SUS) though this is probably degraded by the
ashless dispersant and viscosity modifier additives. Maybe the end result
puts it closer to 100 SUS ? Don't know for sure but the P&W SB does
recommend the use of a higher number with additives.
The only disappointment in the Precision letter was no reference to the
performance of 25W60.

Attention Florida RPA guys.
Like to get volunteers for a 3 or 4 ship formation set for opening ceremon
y on Saturday July 3rd. 1100hrs.
This is for a Tea Party ralley and Independence Day celebration over the
Palatka Water Front Band Shell (5nm ESE of 28J).
Suggest either Flagler or 28J as departure point. 28J (Kay Larkin) would
be better since we would not have to put up with a tower, plus the fuel
is always cheaper.
Thisis for the opening ceremony, which should be a very short flight but
a chance to brush/training up on formation.
Details on contacting me off list.
