Mine came out after a little patience. The first pushed out with a 20 Ton Jack, second would not budge so had the Jack under full pressure until it was solid. I then heated the trunnions and it still wouldn’t budge. I gave up and left it all under pressure, went to do something else and 10 minutes later with a massive bang, lots of flying rust and debris, it popped out about 3/4”. I actually thought my Jack had exploded until I noticed the gap, the entire frame shuck and I had the fright of my life.
