    Crank Won't Turn - Please Help

    I do not know what I screwed up. I am in the middle of a rebuild. I replaced all the bearings and reconnected the rod bolts to the crack. I can not rotate the crank anymore. What did I do wrong? I did torque per the manual and did lube all the bearings.

    If you are running CP pistons, or aftermarket, u must bend the oil squirter some to clear the piston skirt

    Did you get bearings for undersized crank by mistake? Loosen the rod bolt one by one to see when it frees up to find your problem. If still seized loosen mains one by one. Was the crank machined? Does it move at all and just stop at points, or is it seized completely?

    I have also seen that when someone had mix matched case halves.

    I found the issue. One of the rod assemblies was reversed. I corrected it and it turns fine. Thanks for the help.

    I've been able to clear the aftermarket pistons by turning and holding the block of the oiler clockwise - as far as it will go when tightening.
