wildbird Posted July 25, 2009 Share Posted July 25, 2009 I bought a conical engine mount for an O-235 from the Cozy girls. It uses a different rubber bushing than called out for in the plans. The plans call for a 3/8 bolt and it has a 1/2 inch steel sleve that is inside the rubber bushing, and requires 220-320 inch pounds of torque. The engine mount I have uses 1/2 inch bolts and has no rubber sleve inside the rubber bushings. A Cessna 152 has a similar set up and the tourque reqirements are 450-500 inch pounds. With out the sleve it seems like it would crush the rubber bushings to oblivian. Any help would be appreciated. Wild Bird Quote Link to comment Share on other sites More sharing options...
