Ok, so Im having a problem with our water jet, I was running it the other day and hward a bad grinding sound, it turns out the cylinder closest to the electrical is no longer connected to the crank shafts but it's still in the case, at first the shafts would not make a full rotation until I applied a little pressure, I was able to get all the way up to actually take the crank case off, Im just stuck on how and where the shafts disconnects and how to take the crank case off to get inside, I was trained on an omax so have never did this for this pump, any help would be greatly appreciated.

Thank you
