Barry Mount Loading

Attached is the last thing that I have come across put in print about Barry Mont loading and “snubber clearances”…This came after the CMD Barry Mont notes from a few years before

Further to my earlier post, also keep in mind that upon changing out the mounts there is always a chance that there is something that will need attention as to the fastening to the engine bed or stringer, such as stripped holes, problematic fasteners or such. Again much easier to deal with the engines out. Here’s a 17 year old failing mount – basically zero as to marine age but the isolator is done.

15 years, if it were me there is no question there, change them out – the savings in the bloody knuckle labor amount of work to change them out in place versus the near zero work changing them out with the engine’s pulled is well worth the price of admission…

What are the clearances on the bottom rubber snubber? The snubber should be sitting about half way between the mount and the stringer… if it’s sitting lower or bottomed-out, then they will need to be replaced…

Got any good pictures?
