Posted: Fri Jun 23, 2006 7:05 pm Post subject: 601/ Stratus Engine Mount

Yesterday I tried to hang the Stratus EA81 on my  Zodiac 601. Three of the four mount bolts went in smoothly, but the lower left  hand mount bolt misses the hole in the mount by almost the whole diameter of the  bolt.  No way can I shift things around or deflect the legs of the mount to  get the bolt in.  Another local builder had the same problem, but was able  to force a fit.   Has anyone else on the list had this  problem?

  

 I bought my firewall-forward kit, including the  engine mount, in 2000.  The mount mated up with the firewall, no  sweat.  In response to other builder's reports of cracking lugs on the  firewall end of the mount, I had gussets added to those lugs.  Since  three of the engine mounts line up, I doubt that welding induced enough  distortion to create my current problem.   I did modify the  mount, so I'm reluctant to throw the blame on the factory, although  I suspect that's where it belongs.  

  

 Thanks in advance for any helpful  suggestions.

Hi George,

I had something similar, not quite off half a hole diameter, same place, 

but I made it closely to Zenith provided drawings.  Could be that the 

Stratus mounts have us out of position by a small amount?  It still is 

not the fit I'd like either, but it just does and one day I'll pull the 

engine and reweld the hole and drill it down where it should be.

Or remake the Stratus mount to get the adjustment.  I've already made a 

new right upper Stratus mount and it fits fine.

I've never mounted an engine to an airframe, but I remember some 

correspondence on this list some 2 or so years ago where builders forced a 

fit and later cracks were discovered in the supporting frame due to the 

stressed condition.  Just a thought to be concerned about.  Robert

My engine mount was way off too...But to the fireall not the engine. 



I would call Zac and ask 'em to sort it out. You paid a lot of money for

that mount and it really has to be right.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Mine, too, which I received in 1997. Just about 1/8th inch off. I enlarged  a hole a bit and made it fit...390 hours ago. All seems okay.  don  walker
