Engine mount washers

[Ian Comerford]

Years ago I picked up the ‘knowledge’ from somewhere that the washers on the engine mounts can fit either way depending upon what sort of effect you want them to have on the mounts.  Today is saw this on Pelican which shows that ‘knowledge’ was flawed, or maybe for earlier versions.  Interesting!

The stop plates primary job is to prevent the mount totally failing if the rubber bush fails - think of them as a audible rattle alarm to indicate a failed engine mount bush.

Over extended service life the stop plate can spread the weight of the engine over a larger surface of the rubber mount as the rubber begins to sag if used in the 'new' orientation as detailed above - also looks cooler

there is a talk on pelican on this the so called new position is in place already in the late 1980`s;-)))))Personally i always put them facing down and bottom up....for better stability of the engine..................

The 'old' configuration just looks wrong to me.

I've always gone with the 'new' configuration.

You do see a lot of IBs with the washers upwards, so it’s either choice or lack of awareness
