Normally, I move my plane around by the tailwheel with a tow bar. This weekend, I was visiting my brother and mostly moved it around by the prop. I was surprised to find that I have some play, fore and aft, in the crankshaft. I've searched and read about this extensively already (VAF and elsewhere) so I know some play is normal. But, it sure makes me nervous!
I get an audible and tactile "thump" when I push / pull on the prop. So, my first question is - is that normal?
Second question, I read a lot about endplay limits and such but it's not clear to me exactly how to measure the end play (case to starter gear?) and I definitely don't know what excess endplay means to me as an operator. Does too much (whatever that is) mean I"m grounded? Or, do I just check for leaks more carefully? Any help / advice will be much appreciated
