Carefully install the crankshaft into the block.

Make sure the bearings are clean and dry.

Do not rotate the crankshaft after it is installed.

Add a small length of Plastigauge to each bearing journal.

Carefully set the girdle onto the crankshaft. Line it up perfectly with the bearing journals on the block.

The girdle fits very tightly into the block and will not be fully seated until the next step.
