I did that once a long time ago (maybe 2007 or 8), thinking that my understanding was better than the manuals logic. Eventually, I ended up having grease sling out of the hub, and I had the prop re-sealed, which cost I think $860. So, those that doubt the manual can test the theory and see if they have the same problem. That way I won't be alone in the boat. If it happens to a few dozen of us who didn't believe the manual, then we'll know that the manual is smarter, right? But, if nobody else has the problem, then we can know that our vast pool of a couple dozen anecdotal cases are better than the stuff Hartzel tells us. :) I know me, I'm going to follow it to the letter from now on.

Stopped at the hartzell booth to ask them their thoughts. They were very Responsive and concerned. I was then introduced to Scott Foster. Talked to him he got my contact info And called me the week after Oshkosh. They wanted to inspect my prop. Scott came up the next week and we removed the spinner Looked for leaks and determined a zerk fitting was a little loose. And leaking. Tighten it up Then we discussed the amount of grease. I had told him I pumped until Some came out. He said that 2-3 pumps no more. I pumped way more than that. The good news my prop was ok and he Said everything looked great for almost 500 hrs. But he did say no more than 2 pumps and told me not to grease mine at the next annual. Great customer service and Scott is great. Then I took him for a ride in the RV-10. He was impressed with the performance and loved the RV-10. He was drinking the the RV-10 koolaid and loving it.

However, I appreciate this thread and will stick to the manual moving forward. I always worried that I didnt have enough grease, seems that that is normal and not to worry about!

If that's too much and they are recommending something different, shouldn't Hartzell update the procedure in the manual? Then we have the issue of does my gun pump the same volume as somebody else's? It seems like it's still using a bit of magic and luck, since there is no effective method to measure the actual volume of grease until you pump too much and it oozes out the back.

The WAG part: if there's sufficient grease to coat the blade seal to keep it flexible and offer some lubrication to the hub ... it's sufficient.
