| Subject: | 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.

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.
Regards,

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.

temp went down =0Ato 170. When I climbed out and flew back home the temp w
as right on 180, then =0Awould move quickly up and down about ten degrees..
.varying from about 170 to =0A190. I have never seen changes that quick.=0A

Maybe more of an instrumentation problem? Check for intermittent
wiring connection, bad ground. Can you install another sensor and gauge
somewhere? Not cheap or easy, but neither is a new engine or airplane.
Do you have other temp gauges (oil, cyl, etc)?
