Having pulled ours apart at the weekend, this cracking (no.5, coupled with a poor
design) was the cause of our deadstick, not our original conclusion.
Richard, I presume the pipes for the M14P also fit the HS-6? I had a look at G-BVVG
the other day and they look to be the same as on G-YAKH.

I'm sorry to say, but I don't know! As I'm sure you know, the background was
that the Russians developed the AI 14 engine (260 hp) with Ivchenko, and the
design was then taken from them and given to the new design bureau of
Vedenyeev in Voronezh who developed the M 14 P family of engines. At the
same time the Russians gave the design of the AI 14 to the Chinese, who made
the HS-6 with 285 hp.
We have wanted to get into the business of overhauling the Chinese engines,
so obtained an old one, working on the assumption that it was going to be
almost identical to the AI 14 for which we have all the technology and a lot
of spares. However, in the event, it is a very different engine with many
parts that are unique, to the extent that we realised we simply could not
overhaul it!
I can say that the M 14 exhaust has a slightly larger diameter than the
HS-6, and this might well also be the case with the intake tubes, so I
suspect you would need to measure them to be sure.

The intake tubes of the Huosai 6A and the M14P are exactly the same dia.
However the cylinder adaptor has a slightly larger thread dia. and the
attaching nut has a corresponding larger thread dia. so they are not
interchangeable even though the same pin wrench fits both!

| Subject: | Prop won't slow below 70% |
To the brain tank:
I have a stock M-14P motor with a stock hub, Russian v530 paddle prop, and rebuilt
prop governor.
Prop is at 16 degrees per the book. In flight I am not able to get the RPM to
go below 70% even with the prop lever all the way back at the gate. I was advised
to increase the size of the spring in the prop governor but Jill suggested
that with all stock setup that should not be necessary.
Any ideas or thoughts?

The standard R-2 Russian governor will generate enough oil pressure for the
Russian V-530 prop, although you do need to install higher pressure springs
for MT and Whirlwind props.
But I would suggest that you are having a blockage of oil either into or out
of the governor. There are quite narrow oil ways, and a gauze filter
underneath the governor and if anything is blocked, clearly the governor
will not work correctly.

No; Just questions;
Is this M14P on a CJ?
Which book put the fine pitch setting at 16 degs.? That is the correct
setting for the Chinese prop. on the Huosai engine.
The book setting for the V530 with stock blades on the M14P is 14.5 degs.
However that is a different problem than what you describe which I suspect
is an incorrect governor set-up procedure. Have not read it for a while but
If I remember correctly the Russian procedure is poorly written and
confusing while the Chinese is simple and straightforward. Numbers of
course are different! But the basic process is the same.
I would not buy life insurance from whomever told you to replace the
"speeder" spring in the governor. Jill's advice here was most certainly
correct not to mention extremely polite.

The speeder spring was sold (by MT Propeller) to increase the pressure or
the Russian R2 governor for use on early MT9 propellers. Later MT design did
not require the speeder spring. Sometimes we simply added a 1/4 in washer
under the spring.

You should listen to Walt because he is right on the money.=C2- Besides
the incorrect blade angle setting, setting up the prop governor is probably
where your problem is.=C2-=C2- If you haven't set up an M14 prop gover
nor before, it would be best to find someone who has.=C2- Otherwise it tr
uly is hit and miss (mostly miss to be honest with you).
