| Subject: | Re: Hydraulic lock? |
Nobody mentioned that when parking for a long time you'll loose less time and
sweat to drain all oil out of the motor. And when coming back before starting
warm the oil outside the plane before putting it back. Then you'll be sure that
there can't be oil in your lower cylinder?
Plus oil will be warm before starting
The best system may well be this pre oiler and heater but it does cost money. Ok
less than a bent rod!!!
Has anyone on the list experienced such way of doing?

down from the tank. Also, I noted that he only pulled one lot of plugs;
you can get oil in the intake tubes (but more likely with a tail wheel aircraft);
you can have oil stuck in the bottom of the inverted piston etc. After that
length of time, I would turn it through at least 50/60 blades with the plugs
removed. Also, it is a very good practice to make a note of the oil level on
shutting down, and leave that in the aircraft. When you come back, you will then
know how much oil has gone into the engine!

| Subject: | Re: Hydraulic Lock |
Group,
A lot of good comments this morning. I have a couple of items to add:
A link to an article that Carl wrote in 1995; which is relevant to any
radial engine owner: http://www.m-14p.com/hydraulic_lock_cwh_1995.pdf .
We recommend against replacement of a link rod in the field. The rod may
not be the only damage to the engine. Typically, the rear cheekplate on the
crank will turn. (This is secured with a pinch bolt.) If the engine is not
torn down with this existing condition, you will be flying with a wobble on
the front end of the crank. In turn, the cam drive gear will bind and the
teeth will shear. The dual drive gear also typically fails. You have now set
yourself up for a catastrophic engine failure. If you sell your airplane to
someone and do not reveal and perform a field repair of replacement of the
link rod only, you are putting them in harm's way. (My opinion.)
Besides overhauling the M-14P, we do a lot of hydraulic lock and prop strike
teardowns. We see more accessory shaft damage with hydraulic lock than with
a prop strike teardown.
I think pulling a prop through 50-60 times may be great aerobic exercise,
but unnecessary. Yes, fear is good motivator and insurance against
hydraulic lock. It does not take many blades on a 2- or 3-bladed prop to
make sure you do not have hydraulic lock. If the cylinders are full of oil,
of course, it will take more to clear them.

| Subject: | YAKETY YAK FUEL TANKS |
I have just purchased my 6th CJ. It has Yakety Yak fuel tanks installed
in the center section from the bottom. I am considering taking them
out. Does anyone have in information on these tanks? Good or bad.
Thanks Kelley Monroe

Are you sure they are Yakity-Yak fuel tanks. They could be Doug Sap's
tanks. Yakity Yak copied Doug's tanks with less than stellar results.

You could be right, it has been a long time. One other thing if the
tanks are full don't open the cap on the inboard tank, fuel will flow
out and into the center section. The original tank is higher than the
added tank.
