Lehner 2240/6 water cooled..:(

[captain harlock]

Hi all!

I got this Lehner 2240/6 HiAmp for a bargain ($275), but the problem is that it is installed with water cooling device, you know, that sleeve-like thingy that goes over the can with a very small golden plug coming out of it to be connected to a tube.

My question is,

How can I take the cooling device off the motor? That thing is sticking to the can like it was secured with cement. So hard to pull it out.

Any help would be most appreciated. It's very frustrating...:(

Yours,
