RE: Spring Starter Lubrication
I pull the bearing on my 40 off every once in a while and put wheel bearing grease in it. If it is good enough for cars to run years on, it ought work on a bearing that only works when the plane starts. The bearing on mine is more like a ratchet bearing. It only grabs the shaft when the prop is pulled backwards. Doesn't really rotate. I know because I had to press the old one out when the previous owner had pulled the prop back too far and broke the bearing. Only needs to move back about 1/2 to 3/4 of a turn to start a properly primed engine. The moving parts are sort of triangle shaped and rock out to grab the shaft when moved backwards. Then retract into the journal as the spring stops. BTW, Boca Bearing sells them.
