Just curious, did they see anything in the prop that gave them concern? What kind of grease was it?My prop is coming back today after reseal/repack. $1500. Prop was bought in 2016 and never installed. Lesson learned too late - donāt buy a prop until well into the build cycle. I am almost ready to,fly, so I will get some use out of it this time.
Or at least give guidance of what accelerates grease separation and seals drying out. Seems the grease separation is the larger of the 2 issues. Does the "environmental packaging" help the grease separation? Again, data would be helpful.How about packaging every prop in the āenvironment packagingā for shipping from the factory or at least have it as an option. Canāt hurt and might add some extra storage time.
Iām thinking the primary issue is the grease separating. If you have a prop in storage why not periodically, say once a year, pump a tube of the NYCO GN3058 grease through it?
The OP said his prop started slinging grease after 100 hours. Again it makes sense to pump more NYCO GN3058 through it before it starts slinging the grease.
Cycling the grease out to mitigate a potential problem seems more logical than mailing off a a perfectly good prop for ārecreational maintenanceā
The thing is - the hub Is not āfullā of grease, so pumping a boat-load of grease into it to flush the old stuff out is not a solution, it just creates other problems.Iām thinking the primary issue is the grease separating.

As the OP and having gone through the whole processā¦.buying the prop 2 years before flight, storing it in, at times, very warm garage and suffering the consequencesā¦ my advice is to NOT buy the prop until needed. BUT, if you do have the prop for an extended amount of time, keeping it cool may be worth the effort.I guess if you just put the prop in your walk-in freezer the grease will stay put until you are ready to fly. You do have a walk-in freezer in your house, right?![]()
If you have a pre 2020 hub. You can:The thing is - the hub Is not āfullā of grease, so pumping a boat-load of grease into it to flush the old stuff out is not a solution, it just creates other problems.
Nope. It was just the DAR requiring it before he would do the visit. The net effect is positive - apparently, the prop shop did some kind of hub mod. Iāll find out what that was when I pick it up today. The prop shop did tell me that the grease used 11 years ago solidifies with time.Just curious, did they see anything in the prop that gave them concern? What kind of grease was it?
