Subject: | Re: 912 oil pressure help |
I have always been a bit puzzled by the Rotax instruction re: oil
temperature.
The rpm are not supposed to exceed 2500 until oil temp reaches 50+. Now
this can take quite a while, even in summer and in winter a good 10 mins or so,
using up a great amount of fuel (not so important to you guys across the pond
with the cheap stuff).
In addition my voltage reg - and I have tried a couple - will generally not
cut in until revs exceed about 3000 initially, so the battery is taking the
whole load and in winter can get so run down, especially if a start up follows
a longish period of nil usage, that the excitement of the regulator does not
take place and no charge results, even with high revs.
This is not always the case but frequent enough to pose some questions.
Any answers out there please?
Patrick

Anyone know where I can find the installation (and wiring) diagram for
the Icom IC-A200 transceiver? The operating instructions are on their
website but not the wiring detail.
Thanks
Peter

Mike, all i have done is constuct a simple relay PCB similar
to Peters Flap Relay PCB that allows a STICK Elevator Trim
to be used in conjunction with a PANEL Trim - the AUTO Cancel
simply means that you can press trim down on the panel
at the same time as pressing trim up on the stick -or vice
versa, the trim motor will follow the first button pressed.
The Flap Actuation is exactly the same principle.
if you want a copy of the Scematic diagam i can forward
it on to you- it wont be as professional as Peters drawing ,
my will be a photo of my diagram with a simple explanation,

> I recentlty purchased a differential pressure guage to measure pressure in the
cylinders. I have read the directions and am looking for those of you experts
out ther that have experience and that might give a step by step on the use
for our rotax engines. Like pressures to set the guauge that has pressure delivered
to via the outside pressure and what to look for in the other guage . What
noises if any when the pressre in clyn. reaches it max and what gauges are
doing etc. I guess i'm looking for a step by step.
Pressure in is 80 PSI; pressure on the other dial is your reading. If readings
good, say above 70 PSI, what and where you hear anything doesnt matter. I think
both Continental specify 60 as fail.
The trick is to get an accurate reading if really important, as you pull the piston
up to TDC and stop it at perceived TDC. Its easy to cheat a reading, and
you can also change the seating of the rings giving a false, low reading. Never
done it on a Rotax, but working the prop (safety first in working that prop
if she should get away!) through a reduction gearbox + backlash may be interesting.
If elusive to you, maybe you can practice on somebodys direct-drive Lycoming
or Continental. Or ask a maintenance shop when they might do this task
and just watch.
If you're working alone, I recommend you reduce regulated 80 PSI in a bunch, before
disconnecting the tester. Theres hair-trigger pressure on that prop, more
so Id guess through a redux drive in reverse.
However, whether a reading you get, verses an experienced aircraft repairman may
get, is 72, or 78 really doesnt matter. Engine should be at least warm when
you do this, though not always mattering that much. Fly one hour off and upon
landing, repeat test and even get some other significantly different reading.
Im surprised Rotax specifies a direct compression test primarily. Ditto for my
newer Toyota Solara, rather fancy engineering. Not precise, and too much noise
going on for even a helper to detect by sound at appropriate ports a leak past
rings, intake valve, or exhaust valve. Have fun!

Will,
If your oil level was very low, the pump might be sucking air while cold oil
slowly drains from the places it pumps to. After it warms and loses
viscosity, it returns to the pump more quickly, raising the pressure again.
Just a thought.
Donald

Hi Steve,
Thanks....yes, I would like a pix of your diagram. I'm into wiring my panel
at the present time and I have been thinking about how to do the flap circuit.
