Helibilly Posted September 3, 2023 Share Posted September 3, 2023 (edited) I am looking to replace the high speed bearings on the main-shaft and the starter/clutch shaft along with the 4 in the tail unit. Does any one have a source I can purchase these from in the UK? With the original shielded bearings, is it possible to re-oil/grease them. If so, what is the best way to do it?

Paul De Tourtoulon Posted September 4, 2023 Share Posted September 4, 2023 All helicopters have these clutches, you could always modify a car one. Quote Link to comment Share on other sites More sharing options...
