12 blades with the 2 blade prop. 18 blades on the 3 blade prop. The
gear
ratio on the M14P is .658 to 1 (prop to crank).

Hi,
I always does 24 turns, first 6 very slow to let possible oil in
cylinders a
chance to sip out. And the first 12 with a light hand, after 12 turns I
prime 5 times and let the prime fuel help us flush away the last oil.
Then I
do the rest of our pre flight. Just before entering the cockpit I prime
new
5 and another 6 turns light handed DO NOT USE FORCE. I jump into cockpit
and
strap my self in and let the primed fuel get between 2-4 min rest, then
prime 1 for each 10 Celsius below 100 celsius EGT. Pump fuel pressure
and
hit the start button. With this procedure I have had no miss starts and
the
engine has not taken any damage. But remember that overpriming can cause
hyd
lock as well, so it is important to wait the 2-4 min and let the fuel
wapour.
Best Regards
Havard Dale

True.....but......crank turing around 6 times is not completely
true....don't forget the prop makes less turns than the crankshaft (1,54
if
I'm not mistaking...)...i.e. the crank makes only about 4 turns.....
Fly safe!

I believe Ron is ASSUMING you have a 2 blade prop. If you have installed
a 3
blade prop that changes things a bit.

How many blades?
Since any 4 stroke cycle engine cylinder requires 720 Deg. of
crankshaft rotation to complete a cycle then the basic MINIMUM
requirement is two revolutions of the crankshaft. This applies whether
there is one cylinder or nine.
The nine cyl. radial has an 80 deg. cycle interval (720/9). In two
revolutions of the crank all cylinders
have completed a cycle. Two complete cycles are recommended to clear
the cylinders. Therefore with a direct drive engine the theoretical
minimum is 8 blades for a two blade and 12 for a three blade. The actual
minimum recommended is 9 blades for a two blade prop.
For the Huosai engine with a gear ratio of 0.787 the requirement for
prop rotation would be 720 X 0.787 = 566.6 degs or 1.57 turns per
cycle. Two complete cycles would take 3.15 revolutions or 7 blades (for
a two blade)
For the M14P it would be 720 X 0.658 = 474 degs. or 1.32 turns per
cycle. Two cycles would need 2.63 revolutions or 6 blades (for a two
blade) or 9 for a three blade.
More won't hurt but is really not necessary.
What is necessary is that the prop be turned VERY SLOWLY so that at
the first sign of oil from the exhaust turning is stopped (and maybe
slightly backed up) so that cylinder can be completely drained before
continuing.
Cheers;
Walt

Not to be a pain, but how about almost none....
Once I put the oil shut off valve and the oil scavage pump sold by
Kimball http://www.jimkimballenterprises.com/web/m14p.php it has
eliminated the issue for me. Now, I do pull the blades through 6 times
at the start of the day and and 12 (3 bladed prop) after it has been
sitting for more than a day. However, I have never had a lock issue
since installation. Also, i have almost completely eliminated any oil
coming from the exhaust or the intake drains even after weeks of shut
down. Down to just a few drops. I have 300 hours on the system and my
M14P.
I can't recommend the system any higher. Also the folks at Jim Kimball
Enterprises have always been great to work with.

requirement is two revolutions of the crankshaft. This applies whether
there is one cylinder or nine.
The nine cyl. radial has an 80 deg. cycle interval (720/9). In two
revolutions of the crank all cylinders
have completed a cycle. Two complete cycles are recommended to
clear the cylinders. Therefore with a direct drive engine the
theoretical minimum is 8 blades for a two blade and 12 for a three
blade. The actual minimum recommended is 9 blades for a two blade prop.
For the Huosai engine with a gear ratio of 0.787 the requirement
for prop rotation would be 720 X 0.787 = 566.6 degs or 1.57 turns per
cycle. Two complete cycles would take 3.15 revolutions or 7 blades (for
a two blade)
For the M14P it would be 720 X 0.658 = 474 degs. or 1.32 turns
per cycle. Two cycles would need 2.63 revolutions or 6 blades (for a
two blade) or 9 for a three blade.
More won't hurt but is really not necessary.
What is necessary is that the prop be turned VERY SLOWLY so that
at the first sign of oil from the exhaust turning is stopped (and maybe
slightly backed up) so that cylinder can be completely drained before
continuing.
Cheers;
Walt

How many blades does it take to ensure that you've cleared all
the cylinders?
I've heard to pull 6, 9, and 12.

Actually, I do pull the blades through by hand. I was just having a bit of
humor with all the emails about "How many Blades" That is why I mentioned
that it was an "very exciting method" and a "complete understanding of how
well the clean kit is working"
Anyway, how about if we all simply start pulling 20 blades? That way we are
safe from hydraulic lock, and consider the extra blades, getting OUR blood
flowing (or in some cases pass out) before we go on our exciting round
engine flight..........

.....and what happens if it hydraulic locks while you are using the air
start to rotate the prop? Dead stop!!?? Then it's too late. Does your
"shower of sparks" work? You're taking a big risk Kregg. If you pull the
blades by hand, at least you can feel a hydraulic lock.

I usually just leave the mags off and use the "start" button to move the
blades. This way it usually passes well beyond 12 or 18 blades..... This
is an very exciting method, however it will give you a complete
understanding of how well your clean kit is working..............

Hi Dennis;
I am referring to blades. 6 blades is 3 revolutions of the Propellor which
(in the case of the M14) is 4.5 complete revolutions of the engine or 2+
complete cycles of the engine.

Walt,
Please correct me if I am wrong. When you say 6 blades and 9 blades (2
blade prop and 3 blade prop), I interpret what you wrote as 6 and 9 complete
rotations or as I wrote in my reply 12 single blades and 18 single blades.
