Very rarely is the problem with the instrument. I would go for the oil
pressure transducer. Most of the time the oil pressure transducer is
painted brown. It will look like the fuel pressure transducer which,
most of the time, will be painted yellow. If need be, trace the oil
pressure flexible hose from the oil pump back to the firewall. It is
the small hose from the left side of the oil pump (pilot's view left).

I would like to remove my fwd and aft sliding canopies for inspection and R&R of
bearing cartridges, felt trim and polish glass. Requesting a quick briefing
on removal of above parts.
The Yak List is great. I'm learning from all the Q and As.

Good morning/evening, I am new to this forum, new to Yaks and new to flying so
please forgive my lack of forum manners.
I own a Yak18t, I have a million questions but the most pressing at this stage
is the red illumination bulbs which fold down above instruments do not operate.
On the switch panel on the right hand side is a instrument lighting switch and
a variable Pot which I assume operate the lighting. My question; is there a
common problem with the instrument lighting I should look at first before I go
hunting around at all the other possibilities? Is there a fuse anywhere?
Also while doing the 100 Hr I discovered a very large electrical piece of equipment
under the rear seats on the right hand side with plugs and switches on it,
all appeared off, anyone know what this is?
Thank you all in advance
Andrew Park

| Subject: | Re: M14P Oil Check Valve |
Hello,
recently had the oil pump removed to check seals - in the fuel pump as well. The
check valve was an easy push fit, so this was not correct ? Yes, the oil tank
leaks into the engine somewhat, no problem, have fitted a shut-off ball valve
in the feed hose to the pump. What worried me more was the wear on the flats
of the fuel pump drive shaft because this was assembled dry in the past - with
steel dust collecting in the space between pumps - not great for the seals.
So I filled the space with PTFE/teflon grease.
Does anyone have an idea what the pipe connection on the fuel pump is for ? This
leads between the two seals to this groove with holes. I utilized this access
to fill up the space with grease in order to lube the seals : Gasoline is not
great for shaft seals.
Cheers
Vic

OK it was a cheap fix. There was a loose nut floating around in the
instrument. We took the instrument apart, found the nut and re-attached
it.....problem solved. It must have become lodged and shorted something
out. It is fine now. Thank you for the help.

| Subject: | Need Fuel System Parts for TechoAvia SP55 |
Sorting through multiple fuel indication and low fuel warning issues on my TechnoAvia
SP55M.
Going to have to replace the cheap westach guage with one that I can calibrate
to the voltage output of my fuel senders. Anyone have any experience with Aerospace
Logic programmable fuel level gauges?
Also looking for a part. See attached photo. This is a switch that activates
the right fuel tank low light. It is magnetically activated. Could not get any
continuity between the posts. The switch part is glued into the back of this
piece. Would this be a common part with any of the other Yaks or CJ's? I
need one.
Also need a float for the left fuel low indication light. Looked in the tank and
my float don't float.
So if anyone is familiar with TechnoAvia fuel system parts and where to buy some,
please send me the info.
Thanks

| Subject: | Re: M14P Oil Check Valve |
Vic;
I suspect you are looking at the cavity drain line connection. Should be
one on each side of the fuel pump (1/8" NPT). One is used with a fitting
and pipeline to overboard which is checked periodically for any fuel flow
indicating pump seal leakage. The other should be plugged.
