cutting prop off

Anyone ever have to cut a prop off? Mine is stuck and i am running out of ideas. I have been rotating the puller, tapping the side of the hub, hitting the back of the hub, heating the hub, spraying WD40 in the keyway and around the hub. The thing hasnt budged.

I know it seems drastic, but not sure what else to do. I have the puller on there snugged up and am going to leave it over night.

With the puller tensioned as tight as you can, I have had to hit one with a 2 pound ball pen hammer. It popped off. I hit right on the puller bolt head.
My next step would also be with it fully under tension add a little heat on the prop, not the shaft.   They can be pretty stubborn. Heat should grow the prop and help it pop.
Can you see if the keyway is intact or did it shear and spin?

I am using a 2 jaw puller. Checked it this morning and it will still on there. I am going to give it another go after work today.

I will check the key and make sure that it is good. The prop is still lined up with the keyway, so i wouldnt expect that i sheered it.

How much heat are people applying? I wrapped a wet towel around the the strut to protect the bearing and heated the hub hot to the touch, but i could still check it without burning my hand. Do you need to apply tons of heat? To the point where you cant even touch the hub?

How hard is it to drop the entire shaft? I know i would need to pull the rudder and disco it from the trans. After that does the flange that connect to the trans come off easy and it just slips out? I have to repack the packing nut so not worried about that part. Figure then i could put it in a press. Guessing 20 tons would get it pulled

Yeah mo heat than that, It can take it.

Consider icing the shaft for a spell to then hit the hub with MAP gas for a quick heatup with the puller cranked. Keep your hands and face away.

Mine let go a few minutes later after walking away.

It is eating at me so i am going to leave work a little early so i have more time. I will put some ice packs on the shaft and wrap wet towels around that and the strut. Then put the puller on tight and heat the hell out of it. If that doesnt do it i am getting out the angle grinder tomorrow and will cut it off.

If it doesn't work with your 2 jaw puller, let it keep eatin' at you and get something actually built for pulling props.

You might see quite a difference in how it works compared to what I'm imagining is a universal type puller you have right now with slop in every pivot point and hard to keep everything centered to give a straight pull

And....................... you'll have it for next time you need one

Brant,
Congratulations on getting that prop off! Even though the puller worked, I'd suggest looking into a prop puller.


Hopefully you did lap the new prop onto the shaft.
