Guys, I have noticed a heavy grease seeping from the propeller hub onto the blades of on my CJ6. I assume there is a seal that needs to be replaced. Any info would be greatly appreciated.

First determine if there is oil inside the hub when you pull the prop hum dome and piston. If there is, replace both the inner and outer seal on the piston.
Oil inside the hub will spew out on to the blade roots when the prop is spinning. Oil inside the hub is caused by a weak inner piston seal.
Check your log books for the last time the hub was disassembled, cleaned and all bearings and races regreased. If it hasn’t been done in the last 200 hours, it would be a good idea to do so.
Also check the log book to see if the collet seals have been replaced in the last 600-750 hours. Again, if there is no record of it being done, it would be recommended they be replaced as well.

If anyone is doing such prop work in the Pacific NW area in the future, I'd very much like to come and watch/assist... ?

Thanks Dennis, do the blades have to be removed to install the seals? My A&P has no idea.

If you're talking about the collet seals, yes. Then the blade angles have to be reset. If you're talking about the seals in the prop hub piston, no. To grease the bearings, you loosen the large castellated nuts on each side and remove the entire assembly from the hub. What remains in the hub is one flat bearing, one race and a slider. Each side is the same. The other flat bearing is on the assembly you removed.

I noticed that the castle nuts on my prop have rows of drilled & tapped holes, but no screws installed. Photo's of other Housai props show screws installed & safety wired. Is my CJ missing a prop piece? Thanks.

If you're talking about the collet seals, yes. Then the blade angles have to be reset. If you're talking about the seals in the prop hub piston, no. To grease the bearings, you loosen the large castellated nuts on each side and remove the entire assembly from the hub. What remains in the hub is one flat bearing, one race and a slider. Each side is the same. The other flat bearing is on the assembly you removed.

Thanks Dennis, do the blades have to be removed to install the seals? My A&P has no idea.

First determine if there is oil inside the hub when you pull the prop hum dome and piston. If there is, replace both the inner and outer seal on the piston.
Oil inside the hub will spew out on to the blade roots when the prop is spinning. Oil inside the hub is caused by a weak inner piston seal.Â
Check your log books for the last time the hub was disassembled, cleaned and all bearings and races regreased. If it hasn’t been done in the last 200 hours, it would be a good idea to do so.
Also check the log book to see if the collet seals have been replaced in the last 600-750 hours. Again, if there is no record of it being done, it would be recommended they be replaced as well.

Those "screws" hold balance weights. Best to start by leaving them off (unless you have an exact pic of how you took them off and marked the blades, etc.).
Then, get a prop balancer and go for it. It will likely take many tries to get it under .04ips, which is what my buddy shoots for...
