A65 Taper Shaft Wood Prop Removal

[gusc]

I'm trying to remove the wood prop from my taper shaft A65 Cont but it won't budge.

I'm using the procedure I got from this forum and it worked well a few years ago.

I'm at the point of trying to do the 2-2 1/2 turns to pop the prop off but the amount of force I'm applying makes me nervous. I'm using a 4' pipe but it is only making a dent in the pipe by the 5/8" bolt, nothing is moving. I have the snap ring blocked so I'm just leaving it overnight with the pressure to see if that helps.

Any words of wisdom will be appreciated.

I was never able to get more than one turn on the nut up against the split ring. Even with a four foot pipe and tapping with a rubber hammer nothing budged. I've broken enough things to know when to stop!

I finally gave up and removed the prop nuts and prop to get the cowling off. Probably a good thing since the prop bolts and hub had a nice layer of white corrosion which I removed and treated everything with Corrosion-X.

I staked the exh valve but only managed to improve the compression by 10 psi up to 30 psi cold, next door cyl shows 50/70 cold so it is obviously not good. So, I guess it is time to remove the cyl to find out the problem. I tried my borescope but couldn't get a view of the valves.
