First put the crank bearings into the case halves. Heating the case with a hair dryer or heat gun and putting the bearings in the freezer for an hour makes the bearings almost fall into place and no press required. Then install the crank into the case halves and use the case bolts (no special tool required) to evenly pull the halves together keeping cases parallel. Tap the crankshaft ends with a plastic/rubber hammer while tightening the bolts to prevent sticking. Once together, make sure the crank is centered between the cases and rotates freely.
