Last year when we had grease leaking from one of our props, Maxwell
http://hcsweb.com/maxwell/ in Minneapolis was adimit about regreasing it
with a thicker grease than had previously been used. I think they went from
Aeroshell 6 to Aeroshell 5 because they've seen 6 ooze past the seals in hot
weather. Anyway, they had a pretty strong opinion about it and they're well
known as one of the best prop shops in the Midwest. They were also pretty
adimit about not over greasing the props. Infact Hartzell even changed
their recommended practices to specify that you only add up to a maximum of
one ounce of grease or until it flows freely from the open zirk opening,
which ever comes first.

Give Maxwell a call. Paul's Prop Delivery Service ships props at great
rates and with great care!

Is it oil or grease? Some people overgrease the
Hartzell props during maintenance and it slings a bit.

Well, we thought it was oil, at first, because of the streaking, but
when we looked closer at the "bugs" on our windshield, they looked like
tiny little flecks of grease.

There was a trace of oily coating on the back side of one of the prop
blades, which we *thought* was oil, but I suppose it could be greasy
residue, flung under centrifugal force? Dunno.

My A&P did grease the prop hub at our last annual, and the weather has
been pretty hot ever since. This leak appeared (I guess not
surprisingly) on a flight after our first "cold snap" of the year.

I've spoken with my mechanic, and he advised that we clean it up and
watch it closely, but take no action at this time.
