Paul,  I can refer Bobby to stiffer Barry Mounts but maybe this is
something you would like to consider from an engineering point of
view.


Bobby,  Your Barry Mounts are 22002-12.  They have an axial load
rating of 175 lbs. There are four stiffer versions:
22002-13 axial load 240 lbs
22002-14 axial load  380 lbs
22002-15 axial load 630 lbs

There are other Barry Mounts but they will not fit your
installation.  Only order the ones above.

Order from AEK Technology
818-686-1445
Greg or Ken Holz owners.  Talk to one of them.


Jerry,

After 25 hours of ground runs my Berry Mounts failed. I think I
need stiffer mounts. Can you tell me which ones to order?  This is
not a heat issue. But the mounts are in slight compression with the
engine in an almost zero degree up / down thrust line. I actually
have about 1 degree of up thrust to take some of the compression
off the Berry mounts. I was hoping for first flight this weekend.

Thanks,


Bobby

Others with the CCI mount are also having a problem. I think Fred
used 22002-11. They are being replaced with the -14 and seem to be
holding up. I will try the -14's.

Thanks,

Bobby


Bobby,  would it be possible to make a tapered shim to line up the
Barry Mount perfectly?  Jerry

How much boost are you running Bobby? I am concerned.
First Barry mount failure we have had.
