Use a pin to roll out the upper bearings from between
the crankshaft and cylinder block.
To make a pin, grind a 6mm capscrew to the
dimensions shown.
Install the pin into the oil hole in the crankshaft. Rotate
the crankshaft so the pin pushes against the end of the
bearing opposite the tang. Remove the bearing.
Follow this procedure to remove the other bearings.
Inspect all caps and main bearing crankshaft journals.
Determine the size of the bearing removed and obtain
the same size for installation.
Refer to page 5-188 for the dimensions of the standard
and undersize main bearing journals.
