| Subject: | Exhaust manifold donut |
Yes I was simply interested in the dimensions in that a satisfactory seal
seems to have been made with an automotive exhaust gasket, and if that is
the normal "asbestos" with a thin copper sheet on each side, I suspect it is
probably only around 4 mm thick, whereas the standard exhaust "olives" that
we make for the M 14 engine are 10 mm thick, and for customers where the
cylinder head has become worn (through running the engine with the exhaust
nut loose), we sometimes make special order "olives" up to 15 mm thick!

For general information - these items are identical for the M14P, Huosai and
AI14R engines. The attaching nut is larger for the M14P cylinder but the
sealing area is the same.

I believe Doug Sapp has them in stock. If not, then we have them in stock.

Doing the annual on the CJ and found one of the exhaust manifold "donut"
gasket needing replacement. I used an automotive asbestos gasket years ago
to replace one but don't remember the part number. Any suggestions?

Hello Sam,
The M 14 B is a very straightforward derivative of the M 14 P, and in terms
of manuals there is virtually no difference.
Of course the "B" normally has a large hydraulic pump fitted to the rear
accessory case, although this will typically be removed if the engine is
used on, for example, a Yak. And it has a splined propeller shaft rather
than the flat plate of the "P". But again most people would tend to change
the gearbox in order to get an "P" propeller shaft.
But in any case we will send you the link to download the M 14 P manual and
parts list.

Any link for M14B?
Just thought I would ask.

I would be as sure as I can be that this is an absolutely "normal" magneto coil
problem, and the only solution is to change the coils.

Subject: Yak-List: Re: Mag Coils- again
I just started flying the plane and I have an issue that popped up with my mags.
Mag 2 is getting a 200 drop and the 1 is getting between 80-100. The plane ran
well on my checkout but on my first day to solo my run up had issues so I taxied
back.
My idle fluctuations were from 300-360 with the manifold pressure erratic as well.
The only thing I did was that I installed the longer spark plugs that were
BRPs. I wouldnt think that would matter but I cant really tell you how it ran
before because I swapped them prior to these flights. I am a new owner as you
might have guessed.
I was wondering what you think I should check and look for. I just want to take
a look at it and see if theres something that is obviously wrong. Could this
issue be related to mine. My new plugs were set at .020 could have been a hair
more beuse I only had the disc that went down to .020.
What are your thoughts?
SAM

Richard;
When you say 10 mm thick one envisions a solid piece of material. Though
I'm sure you are referring to the overall width which is approx. 10 mm it
could be confusing to those unfamiliar with these engines.
The only exhaust gaskets I have seen for these engines are formed from
steel, probably beginning in tubular form with a thickness of approx. 1 mm
(.04").
The sealing effect is obtained from the spring like resistance to further
deformation under tightening pressure of the nut.

I am no expert on the Nanchang, but the seal between exhaust pipe and
cylinder head can be a problem area with the Russian M 14 engine. We
actually call them "olives", but I'm surprised that an automotive gasket is
thick enough the standard size for the M 14 "olive" is actually 10 mm
thickness, and we produce oversize ones according to a customer's
requirement, and these have been up to 15 mm!
