| Subject: | Purging oil system / Coolant |
Hi! Eoin,
For your thermostat to work by sensing the oil temperature there must be a small
by pass to allow hot oil to begin to heat the THERMOSTAT for it to begin to
work and allow more hot oil through. Unfortunately the process of purging the
oil cooler matrix will take longer since a considerable amount of oil/air will
need to pass through the small orifice.
Yes the coolant will need purging but it relies on you starting the engine and
allowing it to cool a few times and topping up the reservoir to level ( assuming
that the cap seals are undamaged and appropriate poundage.)
I just used my small aircraft tyre inflater to pressure the top of the oil tank
to push the air out of the oil cooler but it surprised me how long the process
took to get the air to gurgle through back to the tank whilst turning the prop.
.... and that was after motoring (ignitions OFF ) with an ignition plug removed
from each cylinder on the starter . But there was no doubt the air was removed
by one hell of a gurgle !!!!
Best wishes
Bob Harrison G-PTAG

Subject: Europa-List: Purging oil system / Coolant
Hi all
Just after completing the 5 year hose replacement on our Europa and Im just wondering
does anyone have answers for the following :
1. My oil system has a thermostat in line, just wondering when purging as the oil
will be cold am I effectively only purging half the system as it,ll bypass
the oil coolers ? Or is there another method of doing it?
2. Do I need to purge the coolant system or once I fill with new fluid is that
me done ?
Kind Regards
Eoin

| Subject: | UNI cloth specs? |
As one of the many who were short changed by Mr. Wilson, I have inadequate UNI
for my project and would like to source locally (being in Ottawa, Canada).
Does anyone have the specs for the UNI cloth? Or must I ask the factory?
Many thanks,

Hi Pete
The original cloth was Interglas 92145 Unidirectional, 220 gm/sq m. The BID was
92125 2x2 twill, 280gm sq/m.
Have a look at http://www.streifly.de/shop%20reparatur-e.htm

Pete, How much do you think you need? I have a reasonable amount surplus
which I could spare you at bargain price - like 10% of 2000 retail
price! Regards, David Joyce, G-XSDJ
PS This is because I bought a complete abandoned (because builder died!)
kit to get the bits I needed for my repairs and have been happy to
distribute the surplus to all parts of the world. Condition
indistinguishable from new.

If David=99s cloth is not enough, I may be able to top it up.

| Subject: | I'm puzzled, again! |
This time it's the old topic of 912 ULS kick-backs on start up. After a couple
of days during which our group members pondered possible causes of this recent
phenomenon, following a long period of relatively trouble-free starting, we reached
the conclusion that the battery has become elderly. The gradual slowing
of cranking speed while engaging the starter, creeps up unnoticed over a period
of years.
A new battery fixed the problem most convincingly, whizzing the propeller around
with great enthusiasm. But one of my group members raised this question "Why
should there ever be any kick-backs at all, even with a tired battery, considering
that we have the latest CDI boxes in addition to all the other measures
recommended to prevent it? After all, the built-in temporary retardation of timing
to 3 degrees ATDC while starting, should guarantee that kick-back can't happen
even with an old battery!"
The only "explanation" I can conjure up is that when overall battery voltage reduces
with age and while it drops even lower during cranking, the built-in deliberate
delay in spark being triggered until after TDC while starting doesn't
function, or only works partially.
How's that for a half-baked theory?
