Hope one of you engine savvy guys knows how to solve this problem.
I was trying to remove the prop from my RV-4 due to a cracked spinner bulkhead. One bolt didn't want to come out.
At first it would back out a half turn, then get tighter. I used a lot of penetrating oil, wiggling, and gradually moved the bolt in and out until it was about 1/4" out. Heard a pop at this point. I think this was the 5/8" bushing coming loose between the crank and prop spacer. You can see that the bushing turns now, when you turn the bolt. (Looking thru the space you get when you pull the prop forward 1/4".)
Sensenich aluminum prop, 4" of spacers and 3/8" prop bolts about 8" long.
Thanks in advance for your advice.
