Make sure you buy, crank seals left and right, new crank bearings and the case gasket. Big old mallet will be your friend getting it out. When you are ready to install, put the bearings in the freezer overnight. Heat the case halves where the bearings go with a torch (install the seals after!!!) Then the frozen bearing will just slip in. Freeze the crank and repeat, heating the bearings. You'll have to put the case halves together pretty quick before the crank heats up, it's a bitch. When you have the case halves torqued up spin the crank and if it didn't e move freely tap it lightly left and right until there is no resistance spinning it.
