I'm dropping the engine in my k9 gsxr 1000 and I've hit a wall at the very last step before freeing the engine. The two rear engine mounts have a bolt going from one side of the engine to the other side, the picture below shows the right side of the bolt and what's involved with removing it.

#28 is the engine mount nut. #29 is the thrust adjuster lock nut which requires a castle nut socket to remove. #30 is the thrust adjuster itself and is shown in the two pictures below.

I've removed the engine mount nut and the thrust adjuster lock nut, but for the life of me, I can not loosen the thrust adjuster, which is what will allow the engine to drop down. As can be seen in second picture, the head of the adjuster looks almost perfectly round, however the last picture shows that there are in fact very slight flat spots on it which would appear as though a socket can be used. All the gixxer forums say a 22mm socket is required, however my 22mm socket does not fit, and a 23mm is too big and spins, imperial sockets also do not fit.

My theory is that the 12 point 22mm socket I'm using can not fit over the relatively large corner sections of the thrust adjuster, I'm wondering if a 6 point 22mm socket would fit. I don't own one and don't know where I would get one, but regardless, I will certainly be able to do that tomorrow.

What I want to know, is if there is another way to loosen this thrust adjuster (without damaging it) without using as 6 point socket, purely because I would like to drop the engine and begin disassembling it tonight so that I can spend tomorrow inspecting damage and ordering parts, rather than spend tomorrow disassembling the engine.
