Aeroshell 5 out of production?

[airguy]

It's significantly cheaper than that for just the hub check on the Whirlwind, I was quoted $1300 if I recall. If the blades are in good shape that's all you need.

I was quoted $2K this week for a blade strip/paint/teflons/reseal for a Hartzell so I suggest anyone shopping for a prop take this into account when making a purchase decision.

The Whirlwind 300 series is 5yr/500 hour teardowns. At least that's what my manual says

P.S.S. Thanks for the link to the grease a while back, I ended up just purchases a can from them.

I agree on both counts. I learn a lot from Joe’s posts, and his tip netted me a tube of Aeroshell 5&6. Thanks, Joe!

The most important thing I can tell you is that you need to poke the hole where the grease is to emerge with a piece of safety wire or a paper clip or something similar. The wax in the grease will make a temporary plug, so poke before you grease. You add 1 oz or until it emerges out the other side. That is all it gets until next year or 400 Hours, which ever is 1st.

Direction is given in Hartzell owners manual 115N

Here is a Hartzell Video:

Please call Hartzell or contact myself with any questions pertaining to greasing your prop.

The shot glass tip is a good one. My Hartzell manual has a note that 1 fluid oz. is approximately 6 pumps with a hand operated grease gun with no mention of gun differences. There are many different hand operated guns available that pump widely different amounts of grease per pump. The one that I have takes 56 pumps per 1oz.. I read this in the gun’s manual and then tested it in a shot glass. It came out pretty close.

Another interesting observation on my two blade prop was that one blade took the full 56 pumps with no grease exiting the lower open fitting, while the other blade took only 40 pumps until grease emerged from the lower open hole. So one blade took a full ounce and the other only took about a 1/2 ounce. Neither blade sheds grease in flight. Not sure what to conclude, but an interesting point.

I just bought 2 tubes of AS 5 this morning, so wanted to let the VAF world know Tiffen Aire still has some at the moment.

This seems like a HUGE number of pumps on a grease gun, at least any grease gun *I've* ever seen/used. If I pumped mine nearly 60 times, I'd have a veritable mountain of grease.

You *sure* it's 56 pumps?

Yep. I measured an ounce from the gun prior to servicing the prop and counted the pumps. It seemed off to me to, so I found the gun’s manual online and verified it. The gun looks no different from other guns I’ve owned, but it is definitely metered differently. That was the reason for my post, so others would know to check their grease guns if they aren’t sure how many pumps deliver an ounce.

Took 24 with my gun.
