The hardest part of the split job is finding the torque sequence numbers cast into the cases. The numbers are in assembly sequence, so when you're separating the cases, start with the high numbers (fasteners on the upper case half) first. If there are a few numbers you can't find, it's not a major problem--just be sure to relieve and apply torque in small increments, working opposite-to-opposite, outside-to-inside during breakdown, inside-to-outside during assembly.
