[NSRCA-discussion] Neu Gearbox Grease Technique

[Scott Pavlock]

Hi All,

Just wondering if anyone has any advice about mow much grease I should pack
into the Neu gearbox when I do the re-grease?

A few weeks ago I did what I now realize was a light pack of grease. I felt
like the gearbox was getting more and more rough over the last couple of
flights, so I decided to do another re-grease last night. When I took it
apart, it was clear that there was not enough in there from the previous
time, so I decided to use quite a bit more grease this time.

After completing it, the gearbox was much smoother when turning the prop by
hand so I felt good about it. Then, after the first flight today, the
gearbox went back to the more rough feeling gear train when spinning by
hand. Is this normal, or should I expect the gear train to feel more smooth
for a longer period after greasing? Trying to gage how much grease I should
be using each time.

Also, is there a sound or feel that would identify that I need to
re-grease? Or is it just best to stick with proactively greasing every 30
flights or so?

Thanks,
Scott Pavlock
