I discovered this thread in the archive:
Which has been very useful to me. We have suffered a CRB failure on our BE3 box, and I now think it could be because the lower bush is yellow and the top bush white. We have the 79mm arms, so I think they should both be yellow. I believe the part I am looking for is 2175 14.
I am struggling to find it for sale, any suggestions?
Also, what are the 'protectors' (item 4 in the diagram)?
