    Default Propeller grease

    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 EX3ís Iíve 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".
