Maybe stupid question, I never thought much about prop hubs, other than the plastic strips fall off, they just work.
Went to change props last night, and the prop came off but hub stuck, not really uncommon, but this time I pull the HB off and the plastic insert that rides on the smooth part of the shaft is sticking out of the hub about 3/8 of a inch, and is chewed up. It was riding inside the red aluminum ring that houses the seal on the imco lower. The seal doesn’t appear to be damaged,(no oil leaking out). The plastic insert from the hub doesn’t really fit in there, thus a bit chewed.
So my question is, why did it move out? My insert as you can see in the pics, comes out with a couple taps from a screw driver.
Are they usually in there real tight? Since I have never removed it, I don’t know.
Should I just put it back in and run it? I don’t know what pushed it out in the first place so afraid it could waste the propshaft seal allow water intrusion, thus fucking up my new SCX and rebuilt lower.(has like 25 hours on it)
Haven’t bought a hub in forever , damn things are $140. Not a big deal if I need one, but don’t want to buy one if 1, you can buy just the insert , or 2 get a new one , and you can tap the inserts out like I did here and I have not really solved anything.
I have ran Thai setup over 100mph many many times, check drive oil a lot, so have removed prop every couple of trips, have never seen this.
