Those of you who have had that happen know what Im talking about. I continued flying it with the prop pitch fixed. How much trouble is it to replace the bearing? Can someone share the experience? Thanks, Sonja ________________________________ Message 2 _____________________________________ Time: 08:39:28 AM PST US From: "Keith Dawson-Palmer" Subject: RE: Pulsar-List: GSC in-flight adjustable prop bearing failure Hi, I had one of the original GSC i/f props, bought while I was building, and on hearing the news of bearings collapsing, I got hold of GSC, because I had planned a long over water flight and couldn't have the prop going to fine half way. They said they had up graded the I/F prop bearings and I think it was strengthened shaft for the 100hp. Rotax. They offered to service my unused prop and supplied an upgraded prop for a reasonable price, that meant I would always have a spare. Unfortunately the new set up does not fit the original design. When I last spoke to them it had changed hands and they had stopped making the I/F which was originally made for the Pulsar. They have retained the jigs etc in case of an increase in demand on the I/F. One of the original builders repaired his I/F with a double race bearing don't know any more, I think the problem was that they used an standard bearing which did not support the side load. Hope this helps.

I will try to find the photos I made of the modified push rod and bearing cup. It is actually very easy to do. I have hundreds of hours on the same bearing. Use a INA DL12 bearing. Barry, did I send any pics to you that you can send to Sonja?
