Subject: JabiruEngine-List: loss of oil.
Has anyone experienced the loss of oil at the oil cooler adaptor
housing O ring? I'm new to flying with a Jabiru engine. My Indus
Thorepedo has only 30 hours on a 2200 engine. I experienced a loss of
oil due to a faulty or undersized O ring on the oil cooler adapter. In
addition I am a little concerned about how the whole oil filter assembly
is attached to the engine block. It seems to me that the entire assembly
is dependent on twisting the oil filter in place. It appears that the
force of the torque on the filter carries through the oil cooler
adaptor. It is the compressed O ring face against the block that holds
the oil cooler adaptor assembly in place. When the leak became evident
it was possible to hand twist the oil cooler adaptor about a 1/8 of a
turn at the engine block. Jabiru just sent me a replacement adaptor to
be installed and needless to say I'll be checking the attachment during
preflights and keeping a close watch on the gages in flight.

Hi! Arthur
In the absence of any other advices from anyone else to get you "on your
way" I can advise that I had a similar problem on a 3300 engine in that
the "o" ring was inclined to squeeze out so that when you removed the
cooler "dohnut" the "o" ring had some extrusion like marks. Firstly I
made sure that the "o" ring was lightly greased on fitment to ensure it
doesn't roll up as the filter canister is tightened. This did stop the
leaks generally but I was hesitant to over tighten the canister.
Latterly I redesigned the system entirely making the oil cooler
selectable and meterable. This utilised a slightly thicker "donut" to
enable the application of standard adapter screw in fittings with
doughty washers sealing them on spot facings on the "donut" perimeter.
This gave me the opportunity to slightly reduce the "o" ring groove
depth after that I never had a problem except I did tighten it more than
hand tight.
I would suggest (without liability!) that you have 0.005" skimmed off
that side of the "donut" and if that doesn't work another similar slice
but no more than 0.010" total. This will increase the nip on the "o"
ring.
Have fun !
Regards
Bob Harrison.

Dave,=0A=0AI have a 3300 that has been in the air for two years. I had the
same thing happen. The groove was too deep that holds the "O" ring.=0AI c
hucked the adaptor in a lathe and turned off about .010" from the back side
to increase the squish on the "O" ring. I have done this to a couple of o
thers also, and now they don't leak. I also put a hose clamp around the ba
se of the oil filter with the screw for the clamp to the front. I safety w
ire the screw to the clamp and then wire the clamp up to the oil press. sen

Dave,
I have over 190 hrs now on my Jab 3300A with no problems with the "O"
ring on the oil cooler adapter. Also, like others I safety the filter.
I put a band of rubber tape around the filter body (for chafe
protection) and then install a hose clamp on the filter. I
then safety wire the hose clamp to the oil press sender.
