RE: ASP/MAGNUM FS400AR Rebuild/Overhaul
My ASP 400 radial engine powered CMP Zero is now ready for engine break-in runs. I pre-oiled the engine well. First I removed the valve rocker covers on all five cylinders and oiled the valve train well. I also placed oil in the crankcase vent and hung the engine nose down. Oil was seeping from the front prop bearing and the valve push rod tubes. I rotated the engine frequently to insure that oil was distributed through out the engine. I sure hope that the engine is now well lubed and I don't have any premature faliures due to lack of lubrication. I noticed that the valve train was quite dry so I'm sure it was wise to do the pre-lube. I still have a problem with one of the ESM electric retracts though. The motor runs continously and nothing happens. There does not appear to be any way to disassemble the retract so I guess I will have to return it to TBM.
Best wishes and good safe flying.
