Neil,
Will your cushion drive be available to us in the US as a
retrofit item for our
RD1 (B or C) redrives ??
Kelly Troyer
Charlie,
Photo attached,. Should the rubber fail then the inner
drive
block will simply lock up on the outer square giving metal
to metal
which should last quite some time (hours) before wearing
either away.
The rubber is "engine mount" rubber so will only deteriorate
slowly and
not just explode and disappear completely. To test for wear
you simply
rock the prop and any more than 1 inch movement would
suggest a problem
as in deterioration in the rubber. I can only get a half
inch movement
which is in the gear drive train. The rubber can be
re-vulcanised if it
is ever necessary. I have now in excess of 50 hours with
the rubber
insert for no visible wear..
Neil Unger.
