Gidday,
I have a second hand engine mount for a Rotax with the old rubbers and
washers. On closer inspection 7 of the 8 silver "rubber mount" washers are
of a thin gauge, and one is quite thick, possibly twice as thick at about
3-4mm. It is also about twice the weight. This mount was exposed to
significant force and has had to be rebuilt, and recertified, however it
stood up well, however the poor washers didn't. I want to get some new ones
and am wondering if anyone might know why the 2 separate grades of
thickness, and whether the thinner gauge ones were never the correct ones,
or vica versa? Thanks in anticipation.
