Kingsley is right. I did some research many years ago, I found that the Eur
opa supplied rubbers were much harder than the Rotax supplied ones (I was t
rying to reduce engine noise levels). Apparently Europa were supplied by a
differnet manufacturer and hardness was notthe same.
I used the softerones eventually and adjusted the engine alignment by using
washers between the engine mount and the fuselage frame. I remember that l
onger bolts were needed.Graham

Roland,
The purpose of the sleeve is to act as a spacer so that the rubbers are com
pressed to the correct amount and no more.
There is no need for the nuts to be torqued as such in this application.
Once the nut starts to lock up because of the spacer taking the load, turn
the nut only enough then to align the first castellation for the split pin.
In fact, depending on how it feels, it might be best to back off the nut t
o the first available castellation.

Kingsley in Oz.
