Thanks MiTasol! Thank you!!!!Manual
No, the RL-15 is the worst thing possible because it won't fit and is very expensive. It is possible that original UC-78 mount isolators are still available. Check with Air Repair and Radial Engines Ltd; they both have websites.Yes, we do plan to run the engine on the stand, so having some sort of isolator is important, but it will be a permanent run stand engine, so we have some liberty in what will work. The mount is secured between pieces of "L" angle bracketry, so the receiving side can be modified if needed; I am assuming the mount side has the isolators pressed in. So really, I think the most important dimension is the press fit into the mount, as I can widen the engine stand support if needed. Based on your info, looks like the RL-15-E is the mount needed. Does that make sense?
That may be rusted in place. If making a better pressing tool doesn't work, there's always the option of reaming it out to a thin shell that can be collapsed. You could also try dry ice on the bushing after heating the mount bracket. Where are you located?Got it! I will scope out the UC-78 option. Thank you!!! We did access the lower left mount isolator this morning. It was all but gone, leaving only the outer bushing, which we were not able to remove by heating and tapping out. See two recent photos. Any ideas on how to remove the outer bushing? (Note: we thought about simply leaving that bushing in place and pressing in a new isolator with a smaller outside diameter, but the inside diameter of the outer bushing is oblong, with a difference of 0.030 inches between minor and major diameter.)
