Tim,
If you go to my web page
http://homepages.together.net/~billvt/
under construction, engine mount crack, you will see photos of the failure of my
engine mount.
I had mine repaired and reinforced as Larry said and I now have over 600 hours
on the repaired mount with no further issues.
Regards,
Bill - N812BM - HDS - Stratus

I guess oil temp would be slower to change, and it could be a cylinder
problem vs a whole engine problem (or instrumentation). Can you add
egt's to see if it's fluctuating on one side and not the other?
Another idea is to get an infrared temperature gun and tie the plane up
and have somebody run it hard while you check each cylinder or keep it
on the same cylinder and see if the infrared tracks the gauge.

Bill,
Your crack is very similar to mine, I believe we have someone in my EAA
chapter that is a good welder, I would weld it myself but I not sure I
trust myself well enough.

Hi Don,
The oddity that this particular thermostat is suggests you call Mykal at
Stratus. Any really quick temp changes would seem to be sensor or possibly
gage
problems. Actual readings can move 10 to 15 degrees in the span of a couple
of minutes due to oil attitude in the pan, but quicker than that, I'd be
looking at replacing
the sensor and doubling the gage for comparison.

Subject: Stratus-List: Re: cooling
My temps are usually very stable. Last weekend I flew down on the deck over
a lake for about six miles, ambient temp about 75, and the engine temp went
down to 170. When I climbed out and flew back home the temp was right on
180, then would move quickly up and down about ten degrees...varying from
about 170 to 190. I have never seen changes that quick.
this afternoon I took off at 180 degrees. On climbout I looked down and the
engine temp was 150. When I leveled off it stabilized at 180. Then went down
on descent, but while I rolled out and taxied back to the hangar it went up
to 195. It was having a tendency to stay too cool while flying. I took off
the belt, spun the water pump and it feels smooth and is quiet. does this
sound like the thermostat? and have any of you replaced that thing or know
where to get one? don walkerhttp://www.matronics.com/Navigator?Stratus-L

| Subject: | Stratus engine mount |
The replacement I received originally had no changes, so I made one myself.
I think in retrospect, the best solution would be to grind and re-weld the
crack and add the cross bar reinforcement.
I donated the one I received to a friend that also had his crack at 65
hours. In weld repair, I'd suggest you get someone that has good skills at
TIG welding or oxyacetylene welding so as to not spread
too much heat into the part. This is a very safe repair if done carefully.

Larry,
I have been trying to contact Mykal for a couple of days, I thought I would
try a replacement before a repair. Do you know do the replacements have any
of the changes you mentioned.

Hi Tim,
The crack you mention is very common with that specific engine mount
adapter. I replaced mine much earlier. The fault lies with the length of
the gusset and the welder's failure to do a full weld around
The end of the gusset. The crack mostly begins at the end of the gusset
where the stress is highest and the abrupt end of the weld causes the
beginning of a crack. Some have welded a strap across the crack like a
bridge after welding the crack back together and that often seems to work .
I built a new adapter which has a longer gusset and it's been fine so far.
If you mention this to Mykal at Stratus, he'll send you a replacement.

Subject: Stratus-List: Stratus engine mount
Has anyone had any problems with the engine mounts supplied by Stratus in my
Zenith 601HD. During my annual I have discovered a crack in the upper right
(passenger side) engine mount. It runs from the front top near the weld
almost half way to the back. There are 140 hours on the engine and all other
mounts appear OK.
