Lehner 2240/6 water cooled..:(

[aqwut]

I had to remove a water cooling jacket off of a 2280, and it was "HELL". I drilled a hole on a 1/4" plate of steel, and drilled another 10mm hole on another 1/4" plate of steel. Then I used 2 big "C" clamps to remove. (Do it very slowly. Also used shock oil on the outside of the can, and some on the inside of the water jacket. I ended up damaging both of the o-rings on the water jacket.
