Removing the cooling tube

Posted by Dave Munger On 2013/1/17 22:56:08

I'm fighting the cooling tube, original brass . . .
trying various ways to pull it from block. It just won't
let go and its starting to damage the end, pliers,etc.

I'd really appreciate any further info. or ideas short of using dynamite. 15th series 120.
Thanks,
