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

Greg or Ken Holz owners.  Talk to one of them.

    Jerry,
    
    After 25 hours of ground runs my Barry 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 Barry
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
