Stuck Grohe faucet handle

[simon10]

I need to replace the hot and cold cartridges on a 15 year old Grohe Seabury faucet and can't remove one of the "cross" handles. Cold came off easily after removing the screw holding the handle on to the stem, but the hot is completely frozen.
After leaving WD40 soaking into the spines for a day I tried using a plumbers handle puller to no avail, it just keeps slipping even if the puller "arms" are held closed with vice grips, I feel like I'm going to break the tee bar if I wind the puller down any further.
Someone suggested soaking with "CRC Freeze Off", but no luck.

Just wondering any one has any suggestions before I attack it with a blow torch and potentially ruin the chrome finish or bring out the sawzall as a last resort. Either way I'll probably end up buying a new faucet.

Thanks.

Sometimes if you tap up from underneath or get a couple of wooden door stops a tap the in putting upward pressure on the handles

Wrap it with duct tape, a lot of tape.

Then grab it with channelocks and rock it back and forth.

If you need to break the stem off in the handle. Then with the splines broke off in the handle, put the handle screw back in and few turns and use a small hammer to hit the screw driving the broken splines out of the handle.

Thanks for your suggestions, but I had to resort to heat from a blow torch in addition to tapping and rocking the vice grips around the handle. Had to do the same to remove the conical trim. At least it was less messy than grinding, either way I'll still need to buy a replacement.
