    Removing rear coupler

    I have the case split because both of my rear seals were blown out. Just wanted to ask the proper way to remove the coupler instead of learning the hard way. Is it right hand or left hand thread? What is the proper way to hold the crank still? It is still all together minus the head being off to be milled and the case being split. (Jugs, pistons, rods etc. are still together).

    Also where is the best place to buy the seals and whatever sealer I need to re seal the case?

    If you have the crank out I would sent it out to be trued and welded! This is your only chance to do so!!!!
    Its just a security measure but in my opinion worth the money but not technically needed.

    I haven't pulled the crank completely out. It is still in the case with the rods on it. I just removed the lower half of the case. Its an OEM crank that only has 7 hours on it. The whole engine was just rebuilt but apparently the shop did something wrong when installing the rear seals as it blew both of them out of the case already.

    That looks like the perfect tool for the job. Where do I purchase one of those? I am guessing sticking a hammer handle or something like that would damage it? Also what is the proper way of holding the crank still?
