Propeller grease

[Andy]

My FX-3 propeller is placarded to use NYCO GN3058 grease. I was cautioned to use no other grease. Unfortunately, I have not been able to find a USA supplier and Hartzell didn't reply to my request for help locating one.

Can anyone point me to a US source for this grease?

Thanks,
Andy

Hi Andy,

All the propellers on the EX3’s I’ve had so far specific this on Page 6-12 of the Hartzell Propeller Owners Manual shows under item C all the approved lubricants. Aeroshell 6 being the one I use, but it lists Aeroshell 5, 6, 7, 22 and Royco 22CF.

It looks like they just came out in January with a new grease callout per this Service Letter https://hartzellprop.com/wp-content/...-366-R00-W.pdf

it says Aeroshell 6 was previously listed so you must have a propeller they manufactured after January.

I found this online for the NYCO GN3058 https://www.silmid.com/us/lubricants...-SAE-AMS-3058/ but not in the US (this from Belgium). Perhaps CC can point us in the right direction.

Hi Dave,

You seem to have walked in the footsteps I made when I researched this. I also have photos of my prop hub and the grease gun that was used when I observed my prop being serviced at Yakima.

8130-3 and inspection records are dated 3/3/2020.

Maybe CubCrafters will sell the grease but I didn't find it listed in their "store".
