just bought a deck for my 12 and need to replace  a couple of spindle bearings.tried to get the pulley off first one and flatend it so before i try the next one thought i would check to see if anyone has found a better way to get them off . the set screw came out all right but would not break free even with heat

I think pretty highly of kano kroil and time. I had to pull a pulley at work, and I put a little tension on the puller and added kroil, the next day I applied a little more pressure and kroil, ect. On day 4 I came to work and it was freed...This pulley had been in place since 49' in a wet location.

 

Also a side tip for kroil...make a 50/50 mix of kroil and butch's bore shine to remove any copper/lead fouling from a rifle/pistol barrel, just cork 1 end, fill it up and let it work for a week or so, you would be surprised at the stuff that comes out of a "clean" barrel.

Sometimes they can just be stubborn.
Here is something you might try to keep the pulley from collapsing... Not 100%, still can damage them, but it does help.

Take an old belt and cut a section that will go all the way around the pulley. Then take a large hose clamp and squeeze the belt into the V a little (seen this done with wire and twisting on big pullies).

If memory serves me right, with the spindle bolted to the housing.

Remove the blade, and pulley set screws.

Use some kind of short pipe that fits over the bottom of the spindle to support, between a concrete floor and the deck.

Find a flat round punch big enough that fits on the top of the spindle shaft and inside the pulley.

Then use a 2lbs sledge hammer or air hammer and bash it down and out.

What ever breaks, bearings, clips can be replaced with new ones and the pulley can be reused, undamaged.

This is what I did on one of my decks

If you do end up destroying the rest, here is a good source for pulleys

and weld in hubs.
